The following is the cony of the essay: ESSAY ON THE CURCULIO. Mr. President ; Ladies and Genile- men of the Association—At your request I will present the knowledge I have ob- tained during the last two years, concer- ning a little darkish, suouted beetle, known by practical fruit growers as the “cureulio.” ‘This little insect, which des- troys such a large portion of fruit in the United States, resembles in shape when curled up, a grape or raisin seed ; it looks very much like a dead plum or peach bud, and is from a fourth to a sixth of an inch in length, varying much in size. This is the insect which practical fruit growers have to contend with. By prac- tical, I mean those who are aware of the destructive habits of this insect enemy of our fruits, and who diligently apply all known remedies to its destruction. It is known, or called usually by unpractical fruit growers, who learnedly talk of its habits, its mode of operation, and of many kinds of preventives, as the ‘ kurkuloo.” Most of these persons never saw one, nor could tell the insect if shown them. An individual of this class, (and a prominent man of Berrien county,) came to me last summer to tell me a secret he had found out about the “kurkuloo.” He said a little fly, the bees, or something laid an egg in the blossom, and when the fruit grew, it covered it up, so that it hatched a worm which destroyed the fruit. Won- derful discovery! Like many of the preventives iu voruc. ‘ Another class of persons write fine scientific descriptions of the cureulio, give it high sounding names in Latin, describe its species, genera, order and habits to some extent. Riley calls it “ Contrach- zlusnenupher.” Faber cails it “ Rhyncha- enus nenupher.” They tell many things useful, and many that practical fruit grow- ers have no faith or confidence in. In fact very many things said only serve to lead us estray. These savans give too much théory and not enough of their own experience and practical knowledge. Hor- ticultural and agricultural papers are full of the silliest remedies and preventiyes imaginable. The consequence is, we look to remedies as preventives instead of talk- ing the book of nature, open daily in our orchards to study their natural habits, and thereby discover the ‘easy and natural mode of their destruction. Of all the modes yet discovered to save our fruit, none is found efficient but Alling the beetles and larvae. So far as offen- sive odors are concerned, either on, around, or under the trees, saving the fruit, we may just as well whistle “ Yan- kee Doodle,” or “ Hail Columbia.” ‘The quicker we discard all preventives but death, the sooner will we come to the practical safeguard to our fruit. The en- tire extinction of the species is not at ‘once to be thought of; but what I call practical fruit growers, can and will keep the cureulio in check so as to be rewarded for their labor and diligence in using those means which are now known to capture and destroy them, That there will be a class of drones, who will leave this work undone, we may expect; but this should not lessen our efforts. It should increase them. ° The different methods for curculio des- traction embrace, First, that of trapping under small pieces of bark, blocks, or anything flat with a surface of from. two to four inches placed around the collar of the tree, after making the ground clean and smooth, so that the curculio can find no other covert near the tree. Most. of you practiced this mode of destruction last year to a considerable extent, with satisfactory results. Your experience was such as to disprove the entomologist’s. as- sertion, that “they could only be taken in limited numbers, when the nights were cool, and before the trees were in bloom and foliage.” Althongh the curculio were not all taken in this way, it has been said to me by intelligent fruit growers, that more were killed last year in this way (notwithstanding the lateness of its discovery), than all that had ever been killed in this fruit region from the first, by all other means. Second, the jarring process, wherein a large sheet is held or spread under a tree, then, striking the limbs with a rubber mallet of two or three pounds weight, the eurculio are jarred down and afterwards killed. Some have the sheet stretched ou a frame, to be carried and struck against the tree; and another mode of jarring is a kind of umbrella frame covered with cloth, and run on awheel against. tree. This is known as Dr. Hull’s machine.— Gen. Ward, of Benton Harbor, has a cur- euho catcher, which is said to be far su- perior to Dr. Hull’s. Although these ma- ehines will catch great numbers of the insects, there are many objections to them. First, the expense of using them; second, the danger of marring the trees in order to use them efficiently in jarring the curculio off; third, with any amount of force in striking the trunk of the tree, only a portion of the cureulio will be jarred off, as I have tested by using a mallet on the limbs immednately after striking the tree with a bumping catcher. I caught almost twice as many. The only other mode is by thoroughly destroying the larvae by picking up the fallen wormy fruit, or letting hogs run in the orchard and make pork or trichina of them before they get to be hard shells or get “their back up.” This method will be effective in destroying thousands a year before they can do us any damage. The curculio are quite-continuous in feeding. Beginning immediately after emerging from the ground, about the las} of July, the curculio commence feeding and continue even as late as October.— They will feed on peaches, blackberries, quinces, and probably any kind of fruit during the latter part of the season. One, or all of these modes combined, will be the price paid in a short time for all the fruit ripened where the curculio has gained in numbers as in this region, in Southern Illinois, and in many other places. Iam told that-at Cleveland it is wearly impossible to raise a cherry, free from this well-known Turkish erescent mark. Every fruit grower who neglects, 2 in this fruit raising vicinity, to destroy this insect thoroughly, is doing a wrong to others, and should be branded with the crescent mark on his forehead which Cain had on his, and he should be driven out to feed like one of old on the grass of the field like the ox, and his lips should never touch our luscious fruits. To my mind some or all of these methods are necessary to success in savy- ing our fruits from this little black snouted cuss, (I do not speak profanely of him, but reverently), 1 mean accursed, as the flaming sword was to guard the fruit of Eden. It is said by persons who have lived in the St. Joseph fruit region from the time the first peach trees were plant- ed, that the apricot, necterine, plum and all stone fruits grown here then, were fair and free from the puncture of the curculio as the fruit of Paradise. Now, with all our efforts, it is thought by good judges (and I have asked the opinion of many competent fruit growers) that we lose from one half to two-thirds of our fruit crop when the season favors anything less than a full general crop. A gentleman rzmarked to me a few days ago, that last year he noticed many oreh- ards which set a fair crop, but the fruit kept disappearing like the summer dews, till there was none left. If we were more thorough in cureulio destruction, it would save Chicago the expense of sending her proposed mission- aries among us, to cenvert us from send- ing them early, ‘“Hale’s early,” that are “somewhat peculiar.” Let us attend to this missionary labor among ourselves, and Chicago go forth with her exuberant feeling of love to the poor “ heathen Chi- nee.” Mr. Elliot tells us, whea he published his book on fruit in 1854, that the eurcu- lio had not been known in the west but a few years; while now its numbers are legion. It swarms on our fruit almost like the lneusts of Egypt. For the past fifty years horticulturists have been look- ing for a preventive to their ravages. Po- mologists have inquired for varieties of fruit which eureulio would not touch, er some application to the tree to make it offensive to them, so as to compel them to leave the fruit in disgust. Notwithstand- ing the curevlio have a preference for fruit of particular varieties and kinds, they are not remarkably fastidious. Their snout was made to drill fruit and it must do it. It must work at some kind of fruit if not as agreeable to them as others.— They cannot be idle. Having read everything my eye ever lit upon about the cureulio, for the last thirty years, it is absolutely astonishing how much has been written on the sub- ject and to hew little purpose. Hx cepg the three methods I have spok- en of as means of destroying them, nothing better ever has been discovered. The many recipes, preventives and meth- ods to save our fruit are innumerable.— An old preventive was to cut down the trees, with the remark “I never get any fruit.” This, instead of killing the de- stroyer, killed the tree. This was effect- ual. Ido not believe anything but death will stop that horny snout from piercing into our young stone fruits. Itis amus- ing to see what is written as successes in saving a crop of fruit, the many recipes given are supremely ridiculous. For instance, sprinkling Paris green under and on the trees; sprinkling dust, lime, sulphur, salt, in the trees ; throwing with a syringe whale oil soap on the trees; liquid manure, etc., ete.; bags of salt put in the forks of the trees ; tobacco water ; sweet elder branches hung in the trees; assafcetida; phosphorus ; tar around the trees ; tarred shingles hung in the branch- es, cotton batting tied around the body of the trees to prevent their crawling up; as though their wings were made for orna- ments and not for use. Some have re- commended plowing them in; spading tnem in; piling large piles of stone around the trees ; paving under the trees, ete.— A hundred of such remedies I might con- tinue to mention, of equal sense and of equal value. While all these panaceas only delude the experimenter and keep him from efficient means of destruction, the curculio enjoys them as a perfumery offered only to his highest sense of en- jOyment as a co-worker in the perfumery art, in its elevating and refining influence upon his race. Nothing short of the flam- ing sword of death, severing the joints and the marrow of them is of any utility, or efficiency. Ladmit that cultivating and passing around the trees frequently, putting chicken coops under the trees or moving around the trees often disturbs them in a measure, and may to some extent save a portion of the fruit. Hens roosting in the trees is perhaps as good as anything but death on them, from the fact the eur- culio operate almost exclusively by night. Fowls only disturb, but do not destroy them, by roosting on the trees. Some one has proposed to raise trees on little islands so the fruit stung would fall inthe water. This only would destroy the larvae, and the same could be done by picking up the fallen fruit; though it is claimed they will not attack the fruit thus exposed to the water because instinct governs them to preserve their larvae ; but this practice of planting trees would be-wholly impracticable to any extent. It is known that the peach, containing the larvae, put into barrels of water will re- main weeks without destroying them, be- cause when afterwards emptied they be- come active and enter the ground, The custom was to pick up the fallen wormy fruit and empty it in the river.— But observation discovered the fact that the peaches lined the shore of the river and lake, where many of the larvae un- doubtedly enter the ground, and come forth transformed to prey the next year on our fruit. I put some apples in a breed- ing jar last summer to let the larvae ma- ture, in order to breed them to the perfect beetle. The apples decayed some where cut. and discharged some liquid in the bottom of the jar with the sweat of the apples. Two larvae came out and I let them lie in the liquid a week or two till apparently dead, bleached white. One day I took them and put them on some earth, and after some time they became somewhat dry aud very soon went freely into the ground. I put some into a jar Sept. 21st, and Sept. 29th the larvae had his wing process developed; Oct. 16th wings and legs were formed, the beetle colored and quite hard, but not come out of the cavity where he transformed. I will here say that a!l the curcnlio I bred from apples were the common plum eur- culio. I do not know of haviny ever seen any of Dr. Hull’s “anthonomus quadri- gibbus,” or apple curculio. We have never carefully and thorough- ly enough studied the natural habits and rules of international law of this Turkish Mahamedan emperor. We know we pay tribute as a Christian people to his ma- jesty. A tribute more excessive than is paid to any monarch on the globe. Yet; 4 we pay—pay—PaAy year after year, with careless supineness of theorizing reme- dies. He takes of our wealth asking no questions for conscience sake, (if con- science a “Turk” has), with a Mahame- dan’s rights, over a Christian people ;:and the most we say or dois, when we are gathered together in full numbers as to- day, and out of his presence ;—‘‘the little AT 9 ad We now want tc marshal our forces, learn all his habits and rules of warfare, and toa man compel his surrender.— Proclaim our rights to our domain—say, “millions for defense but not one peach for tribute.” . It is known in this community that I made the New discovery last year of trap- ping them under small pieces of bark, blocks, bits of boards, lath, chips, stones, pieces of bricks, bunches of matted leaves, corn cobs, or anything with a flat- tish surface from two to four inches square placed around the collar of the trees on the ground after making it level and smooth to the distance of three or four feet from the tree; or if smoothand clean for a larger distance, so much the better. The object of making the groand clean and smooth is, that they may find no hid- ing place but the traps ov coverts pre- pared for them. The curculio is principally a noc- turnal insect in). its’ Habit “Tor feeding and depositing its eggs. They move | comparatively but little during the day except to crawl on the ground, and when in the orchard, under its rubbish, will crawl toward the trees during the day ; especially when disturbed by working the orchard. They crawl with great rapidity and when they reach the tree during the day, until just at evening—very few will ascend the tree if they ean find a hiding place near it. This mode of capturing them the past!was their profession. season was highly satisfactory to persons who properly prepared the ground and traps, except to a tew savans who have spent years in instructing us on their hab- its and the mode of destroying them.— The only crotchetin their mind that I am able to perceive, is that the most efficient way to destroy the curculio was discover- ed by a fruit. grower, and not by a pro- fessional ; and Iam bold to t, not- withstanding the warning uotes of these savans, that this mode will, if followed, asser upse destroy more curculio than any other yet discovered. There are many here to-day who have used all other means, that can bear testimony to its efficiency and sue- cess. Entomologists I highly appreciate as men, and their general benefit as c¢o-as- asistants to horticulturists ; but to pro- claim the futility of this mode of destroy- ing the curctlios in the face ef facts in this vicinity, weakens the faith of plebian horticulturists in scientific entomologists. Thousands, and perhaps millions, of cur- culios were destroyed by this simple way last year, and we hope billions will per- ish in the same way the coming year if there are as many in Berrien county. My friend, Dr. Hull, who came here after the first discovery and saw these in- sects taken from under the traps in large numbers, weut home and made a few ex- periments, and then wrote several col- umns to show that the traps were of little value, contrasting the result of his curen- lo catcher and his traps set. He drew the conclusion that the sheet or catcher must be used, and if used at all, the fruit grower might as well wait and catch them all at once. ‘This reminds me of the man who had his wife cook his supper, break- fast and dinner for the next day, at even- ing, and let him eat it at supper, so as not to be bothered the next day. I shall only further say of the exhaustive article of the Deetor, which considers the trap- ping process as labor lost ; that thousands can be killed before the catcher would be used and this multitude be destroyed be- fore they can do any damage at all. We did not expect success in Dr. Hull jor my friend Riley, (though I think highly of them), for this process of catching curculio with traps was new to them, and they were not expected to be ‘‘experts.” This was practical entomology; science Dr. Hull said when here examining the discovery, that he or no one else ever heard of curculio being destroyed by such means. But with due deference to my friend Prof. Riley, who says that they could only be caught in my traps “early in the spring before the trees were in bloom, when the nights were cool and the days warm :’ I would earnestly say, that we, here in Michigan respect- fully dissent from such hasty conclusion. Such advice and theory is disproved here, as much as his claiming that fruit grow- ers “were under lasting obligation’ to me for the discovery, while still attributing it to Mrs. Wiers,who accidentally found some eurculio gathered under lumber placed in the vicinity of some plum trees, (we are not told how near, nor of any preparation ef the ground,) and in the course of two weeks caught the enormous number ot 161, which a small toad could eatch and swallow in fifteen minutes, and_ still sit and wink for his lunch. But we catch with little bits of bark, ete., two to four inches square, in two or three hours, thousands. Now, how can Prof. Riley claim for Mrs. Wiers the discovery of this process, while she only related the fact of finding them under the boards without stating how near the trees, not even suggesting | the putting of the boards, (we may sup- pose 12 feetlong and a foot Se wide) near the tree or preparing the ground. she simply put it in the vicinity, hi: wing occasion to use it. It is, and always has been known, that Mrs. Wiers’ suggestion was no practical discovery, or like our method of trapping them ; and what she found in regard to catching never suggested anything but a lumber pile, and that new boards. This was before the trees were in bloom. No- body heard any more of it until our dis- covery, then Prof. Riley brought it up— In his exhaustive report to the Missouri and Illinois Horticultural Socicties, as to the wltima thule of curculio destruction, he not only discarded it, but all methods except jarring, hogs, and picking up the fallen wormy fruit. Here we join issue. Michigan may use all of these, but not solely ; we will use the traps whatever else we use. Last year I used nothing but traps, and proved to my satisfaction their superiority over the jarring Bese But there is uo objection to using traps, catchers, sheets, any and ali means that will destroy a single curculio. Let all these be used! Do not discard any meaus that kills a sin- gle curculio ! Tnis method of trapping was published from east to west, from north to south over as Union—in two weeks time, and tried us an experiment in all parisers Where the EyBEarAION was proper and not too late in the season, persons de- stroyed the beetles in large snumbers. In this vicinity it was very satisfactory. I | have received the highest testimony of its success, while Mrs. Wiers’ discovery was still-born, and buried without a christen- ing ceremony or name. It.was only resur- rected to take fromvaspiring entomologists the cloud of surprise that all horticultu- rists expressed, that they had not before discovered so simple a remedy. Prot. Riley’s experiment was no better than Dr. Hull’s with traps; from his experience and practice he warns all his Michigan friends. against any confidence in them. This is oratuitous advice. It would be goodiftrue! We have, however, learned by practice, to put faith in curculio traps. Sincerity or pride might have prompted this advice to destroy our confidence in this successful mode of capture. Last fyear curculios were killed by thousands and hundreds of thousands, yet. the major- ity who used the traps began late in the season. My curculio crop amounted to over 40,000 by actual count, and mostly from 400 trees. It was thousht gener- ally a better year for curculio than peaches. In 1868 the crop of endlias shipped from. this port was about 525,000 bask- ets. In 1869 about 7 50,000. In 1870 about 157,000. In 1868 and 1869, T jarred the trees, using a sheet as others did. In 1870 I used nothing hut the “Ransom method,” as my friend Riley terms it. Now compare the number of baskets of 1870 with those of 1869, and the erop will be seen to be from one-sixth to one-sev- enth; but my crop last year, 1870. fell only a little short of half as many as in 1869, and was as large as in 1868, (when T used a sheet,) into 102 baskets ; while the ratio of 1868 to 1869 was about five- sevenths as many. [ had about half. as many in 1870, when there was only about one-seventh as many as in 1869, and’ my Late Crawfords bore well. In 1870 the freeze of April 16th, we all know, killed most of the early and late Crawfords, so that I had no Crawfords to raise the re- lative proportion of the two years. Now, why was my crop about half as large in 1870 as the year before, with a full crop of. Crawfords, while the general last year’s crop averaged only about one- seventh? I know of no reason except the faithful attention I gave. from about May Ist to July, in trapping the curculio. From the faith T had in the efficiency of 6 this method, and the want of faith among some prominent horticulturists, and the discouraging manner they spoke and wrote of it, I raised my back a la curculio to fully test its efficiency. To show the result of this confidence, and to put all theorizing at rest, I wiil here state my most careful investigations and experience as to the loss of my last year’s crop by the curculio. From previ- ous statements it will be seen that my crop of 1870 bore about fifty per cent. ratio to the large crop of 1869, while the general ratio of last year was only about one-seventh of 1869. I carefully picked from the ground and from the trees during the entire season, all wormy and blasted fruit. I cut this fruit carefully by hundreds to form as accurate an estimate as possible of the per cent of the wormy to blasted peaches. I counted at different times the number of these peaches in a basket. I estimated that for the season an average of 2,400 of these small peaches filled a basket. I picked the very smallest. I found the basket averaged about one half wormy and one-half blasted. Reducing all of thuse picked up to baskets, gave me the number of peaches destroyed by the cur- culio. Allowing 125 good fair ripe peach es as the average of a basket, gave me the number of baskets lost by curculio. The result was, (making estimates large enough) 257 baskets. In this estimate I was exceedingly careful, and I think I fully covered the loss, which I think was tribute enough to the curculio ; 257 bask- ets at one dollar per basket is $257. That was my last year’s tax collected by his Mahamedan highness. I will leave others to figure up and take their receipts for custom dues to his im- perial majesty. I have asked a large number of fruit growers what per cent. of last year’s peach crop they thought was destroyed by the curculio. None say less than halt, many, very many, two-thirds.— With these estimates I agree as to the general crop. Some, however, lost all their peaches by the curculio. The peaches were saved in the ratio of the diligence used in destroying the eurculio. Now if half the crop was destroyed by them in 1870, and peaches brought $1 per basket, they destroyed $157,000 worth of peaches. If two-thirds were destroyed, this fruit region paid tribute to ‘in Kansas. them last year of $314,000. I simply ask can we afford to pay it? I answer no. If there is any way to redress this evil, let us do it. I am not speaking of any curculio but the one that attacks our cherries, peach- es, and plums, and, so far as 1 know, the same one attacks our apples; for I have bred several from apples the past year, and they are all conotrachaelus, and not ef the quadrigibbus species. ‘There are a hundred kindred species of snout beetles that are puncturing all fruits and nuts.— One species last year destroyed all the black walnuts on the rivers and streams Every species has its pre- dilection for fruit. Last year, the first and second days of May were warm, and brought the curculio from their hibernating places. Being on the watch for them, I began to study their habits, and gained apointinadvance of what I learned the previous year. I ex- amined in the cracks and crevices of the ground near the trees, and found them hid away. I then searched under leaves, sticks, and lumps of dirt. There I found them. This gaye me the hint to save them the trouble of looking up a lodging place for themselves, so I smoothed down the ground and put down traps of various kinds and sizes until I found traps » suc- cess. I will here again say, that to sue- ceed, the ground must be made smooth and clean, so as to give them no hiding place near the tree but the traps. The majority do not fly after enteriug the or- chard, but remain on the ground during the early part of the season, except as they ascend the trees on warm nights to feed, and descend for shelter in the morn- ing. During this part of the season, I dis- covered no difference in any kind of traps if properly put around the tree. After the weather became warm. but few were found under stones or pieces of briek. I have used everything for a trap as an ex- periment, I like pieces of old dead black oak bark, from two to four inches square. Take that which has fallen off and worn the ross and little fibrous bark off, so as to have no cracks in it for the eurculio to hide in. One side is concave, the edges are generally uneven, so that when put up to the iree they give holes for the beetle . to crawl under next to the tree whenidesc- ending. ‘This hollow in the inner side ‘of the bark, when placed on the smooth ground, gives a sufficient vacuum for them to attach themselves to the bark and just clear the ground, which they seem to prefer. The traps want but a small space beneath, say a quarter of an inch, and all the edges close to the ground, only just so that a curculio ean crawl under in several places. I prefer bark because it has a concave side, and does not warp with the sun, while most other traps warp and leave the edges too high and the cen- tre toe close to the ground. Lath, blocks, chips, bits of boards, (unless of the size we may suppose Mrs. Weirs’ were, viz: building lumber), are either eonvex or warp with the sun and raise tke edges, thus bringing the centre to the ground.— Observation and experience will teach any one tosucceed. The traps must all be set over after a rain, as it closes the edges with dirt washed up around them. I followed the traps daily from the first of May to the first of July. There were but few days that I did not catch curculio steadily. On June 23d, 24th and 25th, I caught about as many as any days after the first week’s trapping, and more than on any but three or four days. On the 23d, 298; on the 24th, 361. The ther- mometer ranged from 96° to 104°. These curculio [am sure were not that year’s brood. Some things I think I settled definitely about their habits. On their first appearance in the spring they are active, nightly feeders, if it is sufficiently warm. They ap- pear in the orchard as soon as it is warm enough to start the leaves and fruit buds. They feed voraciously on warm nights*on the tender starting leaves.— When it is eold they do not feed. They ascend the trees just at evening and descend in the morning to find hiding places on the ground. «A tew will be found on the underside of the lateral limbs. They will principally hide under the nearest covert to the tree, Very few remain on the tree. When the trees are in full foliage cur- culios will not all descend every day; but they travel a good deal except when the female is laying eggs fast and is sluggish. When not found under the traps daily, go through the orchard with a rubber mallet | and jar the trees thoroughly as with a sheet, and let the heetles fall on the lof July. most of them under the traps. To test the matter whether they feed nights only, and went down in the morning, which I had observed them doing frequently, the sun half an hour or so high. I went thro’ the orchard to about a hundred trees, at 6 o’clock P. M., and found from five to ten to the traps of each tree. Then again about dusk I took my lantern and went to rows of trees alongside of those where I found them before sundown, and exam- ined about the same number of traps and found only one curculio. Then the next morning at sunrise, I went to the same trees I visited with the lantern and found from five to ten under the traps of each tree. To see if lights would attract them I spent several warm nights until 10 or 11 o'clock burning bright fires with small brush ; most other insects were attracted, but not a eurculio, not one! They probabty, when under the traps, remain there during the day, so that per- haps it is well to examine them in the afternoon, and especially later in the season when if may be best to jar the trees in the morning, and then give them time to crawl under before examining the traps. The curculio began here last year to deposit their eggs in about three weeks from their first appearance, or from May 20th to the 22d. The first peaches I found from which the larvae had escaped was from June 26th to the 26th. I put the Jarvae into a breeding jar June 26th; they immediately entered the ground.-— Between July 20th and 26th the beetles began to come out. They usually pass from twenty to thirty days in the ground ; the majority from twenty to twenty-five days. It thus stands very nearly: May 20th they begin depositing their eggs; June 20th the larvae begin entering the ground ; July 20th the first beetles begin to come out of the ground. Last year but few if any peaches were punetured by the curculio after the first Not later than July 6th I am sure, if really as late as that. The only ripe peaches we find many worms in are Hale’s Harly, which began to ripen Au- gust Ist, and there are no peaches found with worms in of conseqnences after a week or ten days’ picking, and these con- tain larvae nearly mature. This, allow- ing four weeks for them to mature in the ground. In the afternoon you will have |peach, shows they do not deposit eggs “ much if any after July Ist. Then, the more succulent and ripe the peach, the longer they remain in it, and the larger the larvae grows. This settles beyond all doubt to my mind that we are cursed with only one good healthy, active working crop of cur- eulio a year. Ihave no doubt but all curculio larvae perfect the beetle state and leave the ground the same year, no matter what time they enter the ground. I know it is thought the majority remain in the ground till the next spring. I be- lieve every one transforms the same sea- son. I kept them as late as Sept. 21st, before letting them enter the ground, and Oct. 16th an examination showed the perfect beetle, black but not yet emerged from the transforming cavity. About June 25th I put dry hard little peaches containing larvae in a jar without dirt or moisture. They will not die for a long time. ‘They will not transform except in the earth. Many ofthese I kept ull into September. During the summer I took Jarvae at different. times from this jar and examined them, and put them in earth, from which as usual they went through the transformation in’ 20 to 30 days. All the old horticultural works, as well as many horticulturists, now think they remain in the ground until the next spring. This is disproved beyond a doubt to my mind, The number of eges a single female will deposit in one season remains unknown so ‘ar as my knowledge goes, As to their hibernating locality, or place they have the mastery of me. I have prepared what I supposed were attractive places in my orchard for them, and day after day examined them with care, and also other places, late last fall and this winter, but am yet ignorant ef where the beetles pass the winter, except what oth ers Say; of which Iam very distrustful. From the testimony of many it seems that they gather in numbers in old stumps, logs, and under the bark of trees or tim- ber. tigation. er clue to their future destruction. Perhaps I should speak of Prof. Ril parasites of which he has wriitep. I S ’ ry is feast ona good fat curculio ege, fram which he turned continuously, as much as But this thing needs further inves- | If true it may give some furth- | have | seen them and tried hours to have cne! rad to say: No, [thank you sir. And as to his selling Illinois fruit growers next year a parasite that destroys the mature lar- vae, I fear he has stolen my thunder.— When he was here in Jast June, I showed him the parasite larvae, which was new to him, and he requested me to breed some. I can furnish him a pair now to go into their propagation in advance of waiting until next summer to supply Hlinois horti- culturists at $1 or $2 a pair. Michigan will keep under her curculios with the Ransom traps if we attend to it as we should. Ihave here in this vial some of the perfect fly of this new “Michigan” parasite, so that when Prof. Riley begins to sell, you may all know it in advance of his sending them forth to the world claim- ing its discovery. Thishttle wasp-like fly as you will see its ovipositor can reaoh the enrculio larvae in the peach and de- posit an egg on it, which grow together until the parasite larvae kills the curculio larvae, and then furnishes itself a cocoon and transforms in the same peach. I bred large numbers last year. If they should increase much, they will be of some use to usin killing the curculio larvae ; unless we export them to Missouri, HIlinois or somewhere else so ,as to have ashort supply here. There are many things remaining of much importance, which I have not time to present; as I have already trespassed long on your pa- tience. Discoveries remain tobe made as to their natural habits. Do they live oa from yearto year? How many eggs does a single femalelay? What lenethof time ‘is consumed in laying? where do they hibernate? Let these be fully settled. is it known certainly that birds eat the beetles? Do hens or chickens eat the ‘beetles? Lthink toads do, although I }am not positive. We all need to study fur- |ther the habit cf this little insect. Let the name cureulio, which sounds from Maine to Iiorida, from the Atlantie coast |to the Rocky mountains: which echoes from the valley, from the plain, and from the mountain tops, be the tocsin note in | ithe ears ofevery fruit crower, to arise like ithe angel of death and swear that his crescent mark, shall be the insignia of his a coh doom ; that the cureuho shall be no more. That our fair fruits shall blush in the sun ‘beams without his unhallowed touch. L * 4 yNeAg TS WGN
