82 INSECTS OF ECONOMIC IMPORTANCE 



The STRAWBERRY WEEVIL ^"^ (AnfJiouoinus signa- 



His) 

 Order — Coleoptera 



This is a small beetle about one-tenth of an inch 

 long- with a rather long proboscis ; it is usually more 

 injurious farther south and in the southeastern part 

 of New York State. 



The weevils emerge from their winter quarters 

 early and the females deposit their eggs within the 

 buds of strawberries; the beetle then cuts off the 

 flower-stem and the bud soon falls to the ground; 

 the grub lives inside of the bud on the poilen and 

 changes to a pupa from which the beetle emerges 

 later ; evidently but one brood a year. 



Control — ^If possible plant mostly pistillate va- 

 rieties with just enough staminate varieties to cross- 

 fertilize them; plant early-blooming staminate va- 

 rieties as trap crops ; cover beds with muslin ; place 

 beds in open fields away from fences, hedgerows, 

 etc. ; practice clean culture ; dust plants with a mix- 

 ture of sulphur 5 parts, and powdered arsenate of 

 lead I part; begin dusting as soon as weevils are 

 seen and make two applications one week apart. 



The strawberry leaf-roller ^^ (Ancylis comp- 



fana) 

 Order — Lepidoptera 



Moths appear in early May in New Jersey; lay 

 pale green eggs mostly on the undersides of leaves ; 

 these hatch in about one week; the young larva 

 feeds a day or two on upper side of the leaf but 

 soon folds the halves of the leaf together, tying it 

 securely with silk and lives within fully protected 

 from insecticides; becomes full-grown in about one
