Otiorhynchus sulcatus as an enemy of the vine in the lie d'Oleron, M.

 Inst. Agr. [Romel, Mo. Bui. Agr. Intel, and Plant Diseases, 5 (1914),- No. 11, 

 pp. 1533, 1534). — This weevil appeared for the first time in 1913 as an enemy 

 of the vine in the Jle d'Oleron, France. 



The adult weevil devours the buds and shoots of the vines, and the larva 

 feeds on the roots of this and other plants, including the strawberry, raspberry, 

 peach, etc. " Of the various methods of control, the simplest and most effica- 

 cious consists in collecting the adults in traps consisting of tufts of grass, moss, 

 or dried leaves, exposed at the base of the vines and inspected daily. A local 

 syndicate collected as many as 90 lbs. of insects in two weeks by this method, 

 and it requires about 7,000 insects to weigh 1 lb."
