ANNOUNCEMENT. 



Wo liercby announce, by (ho inutujil consont of 

 l)i)lli imblisliers and editors, that tlic Amkuk.an 

 ICntomoi.ogist and Botanist will be sus])L'nded 

 iliiiinif the year 1871. It is unnecessary to give 

 the several reasons which have induced us to 

 adopt this course. Few i)crsons are aware of 

 the l;il)or required to conscientiously manatee a 

 JDurMMl of this character, and (lie health of llie 

 cntonioioji'ical editor has been so poor of late, 

 and his other duties are so pressing, that he will 

 be glad of the respite which this suspension will, 

 in i)art, atl'ord. 



The suspension of a JourM;il is generally looked 

 u|)on as i)ortending failure and discontinuan<'c; 

 but in (he prcstnit casc^ it has no such meaning. 

 One more miniber, which will completer Volume 

 1 1, will be issued before the end of the year, and, 

 nothing pnsventing, Volume III will connnence 

 with (he Mar 1S7l'. All those who receive this 

 aimounccmeiil witli regret, and who intend to 

 renew their subscriptions in 1872, will do well 

 to signUy such liilention to the i)nblishers.

Aftci' a series of experiments, inslilulcd the 

 past, Slimmer, we have proved that, after all, the' 

 hay-band around the trunk of the tree is a more 

 cll'ectual trai) for the Apple-worm than the rags 

 placed in the fork of the tree. There is no superi- 

 ority in the r.ngs over the hay-band, uidess the 

 former are made to encircle the treeasthorougly 

 as the latter. Where rags arc placed sinijily in 

 the lorks.niany of the worms i)ass down the tree 

 from the outside of the branches. If the rag is 

 tied around tlic trunk, it will impede almost 



every worm that crawls down tla^ tree from the 

 fruit which hangs on, or that crawls nii the trunk 

 from the fruit wliii^h falls; and it then lias a 

 decided advantage over tlu; hay-band, because 

 itcaiHiitherbe passed thi'ougha roller or scaldi'd, 

 and used again. 



II has been very generally accepted in tliis 

 coiinlry (hat the Codling Moth is double-brooded, 

 aiul in all our writings on the subject we havi! 

 stated it to be so, (hough no one, so far as we are 

 aware, ever i>roved such to be the case beyond a 

 doubt. Mr. P. C. Zeller, of Stettin, Prussia, 

 informed us last wilder (hat it is only single- 

 brooded in (hat part of the world, and Harris 

 gives it as his opinion (hat- it is mostly so. 

 Now, such may no( improbably be tlu^ case 

 in nordicrii Prussia, an<l the more northern 

 of the United States, though we incline to 

 lieliex'e otherwise. At all events, this insect is 

 invariably double-brooded in (he latitude of .St. 

 Louis, and its uatuial history maybe briedy told 

 as follows: Th(!firs( modis appear, and begin to 

 la>- their eggs, soon after the y(ning iipi)les begin 

 (o form. The grea( bulk of (he worms which 

 hatch from these eggs Icavi? the fruit from the 

 middle of May to the middle of June. These 

 spin up, and in from two to three weeks produce 

 moths, whii-h jiair and in their turn connnence, 

 in a few days, (o lay eggs again. The worms 

 (second brood) from (hese eggs leave the frui(, 

 sonn^ of (bem as early as the lirst of September, 

 others as late as Christmas. In either case they 

 spin (heir (cocoons .as soon .as they have left (he 

 apples, but do not assume the pupa stat(^ till to- 

 wards spring— the moths from the late matured 

 worms apiicaring almost as early as those from 

 the earlier maturcil ones. The (wo broods inter- 

 lock, so that in -Inly worms of bodi maybe found 

 in the frui( of om^ and the same tree. We have 

 re|)ea(cdly (aken worms of (he (irst brood, bred 

 (he modis froiu (hem, and obtained from these 

 moths (h(! second brood of worms; and we have 

 done this bodi on enclose<l fruit hanging on (lie 

 (ree in the open air, and on plucked fruit in- 

 doors. In (lie latter (experiments (he modis 

 would often cover an appli' with eggs, so (hat 

 when the worms hatched thev would enter from
