Felt (E. P.). The European Corn Borer in New York State. — //. 



Econ. Ent., Geneva, N. Y., xv, no. 3, June 1922. pp. 236-238. 



Nearly 5,000 square miles are infested by the European corn borer 

 [Pyrausta nubilalis, Hb.] in New York. In this State under present 

 conditions breeding in weeds, etc. is apparently restricted to the 

 vicinity of maize. The possibility of furtlier spread and increased 

 infestation is pointed out [R.A.E., A, x, 211].

Most of the literature with regard to Tenebroides mauritanicits, L., 

 indicates that, as a rule, its life-cycle requires one year. Recent 

 observations indicate the possibility of a much longer Hfe-cycle, the 

 larval period alone lasting from 628 to 1,248 days, with an average 

 of 822 days for 11 larvae. Although the conditions under which 

 these larvae were reared vary somewhat from those occurring in nature, 

 they are not considered sufficient to account for the difference in the 

 length of the larval period. 



These observations, though not very extensive, indicate the import- 

 ance of undertaking further study in connection with this beetle. 



Marcomtch (S.). The Strawberry Weevil cutting Apple, Tomato and 

 Cotton Buds in Tennessee. — //. Econ. Ent., Geneva, N. Y., xv, 

 ■ no. 3, June 1922, pp. 244-245. 



Anthonomiis signatus, Say, is recorded as breeding in the buds of 

 apple in Tennessee. The infested trees were adjacent to a strawberry 

 patch that harboured the weevils, but whether this pest will continue 

 to breed only in apple buds that are near infested strawberries is 

 uncertain. Buds of tomato and cotton were found girdled, but in no 

 instance were any eggs seen on these plants. This was conhrmed in 

 the laboratory with newly emerged weevils ; these are unable to 

 oviposit until the following season. Under natural conditions the old 

 weevils have probably disappeared by the time the cotton squares are 

 put out.

According to Aldrich, Cryptochaetum monophlebi, Skuse [R.A.E., 

 A, ii, 307 ; v, 11] is a sjmonym of C. iceryae, Williston, both Skuse 

 and Knab having been mislead by a mistake in the figure accompanying 

 Williston's original description of this Agromyzid. 



SxAPP (O. I.). U.S. Bur. Ent. Arsenate of Lead Spray for Plum. 

 Curculio kills Grasshoppers. — //. Econ. Ent., Geneva, N. Y., xv, 

 no. 3, June 1922, p. 247. 



Owing to the unusual abundance of Schistocerca americana, Scud., 

 during the latter part of April in peach orchards in Georgia, poisoned 

 bran bait had to be resorted to in some cases. Most of the feeding 

 was done before the third lead arsenate treatment for the plum 

 curculio [Conotrachelus nenuphar, Hbst.] was carried out, but when 

 the spray, which contained 4 lb. powdered lead arsenate to a 200 U.S. 

 gal. tank, was applied, it proved equally effective against the locusts, 

 causing practically a hundred per cent, mortality.
