NOXIOUS INSECTS 



ISrOTES OF THE YEJ^E/. 



[Under this head 1 here coutuiue the brief notes and observations of the year on 

 such insects as have been ah-eady treated of— observations not recorded in the previous 

 reports, to whicli tlieyare supplementary.] 



THE CODLING* MOTH. 



The first larva^. were obtained under bands, in 1873, on the 23d of 

 June. The first moths were noticed on the 8th of July. 



In most parts of the State the apple crop was, compared with the 

 average yield, a failure. The trees were profuse with blossom, but 

 the late cold, wet weather caused the young apples either to fail to 

 set or to wither and fall soon after setting. With a short supply to 

 work on, the efi;ects of the Codling Moth were all the more apparent, 

 where no means were taken to prevent them, though the insect was 

 less numerous than usual. What with its injuries and those of the 

 Plum Curculio, which, for almost total lack of stone fruit, worked more 

 than usual upon pip fruit, the few apples harvested were of inferior

Respecting the kind of bandage best to use, last summer's experi- 

 ence confirms that given a year ago. 



The leading article in Dr. LeBaron's Report for 1873, as State En- 

 tomologist of Illinois, is upon this insect. In said article are detailed 

 a number of interesting experiments and observations which fully 

 corroborate what was already on record of the insect. It is well 

 known that a certain proportion of infested apples remain on the tree 

 after the worm has left them. The proportion will depend very much 

 on the variety of apple, and on the time of year that the worm ma-
