The strawberry weevil in Minnesota, Anthonomus signatus, S. Marcovitch 

 {Rpt. State Ent. Minn., 16 {1915-16), pp. 109-134, flffs. ^).— This report of in- 

 vestigations, commenced in 1914, is summarized by the author as follows : 



" In Minnesota the adult weevils make their appearance the latter part of 

 April or early in May, feeding on the underside of the leaves until the pollen is 

 mature. The buds are first cut as soon as the first blossom shows and the fruit 

 pedicels are about 2 in. high. Fields with from 40 to 95 per cent of the buds 

 cut were not uncommon. The new brood emerges soon after picking, eating 

 small holes on the underside of leaves. Hibernation began the latter part of 

 August in 1915, among the dead leaves in the strawberry patch. The weevils 

 pass the winter in the strawberry beds and not in the woods, at least in Minne- 

 sota. Old beds are more severely infested than younger ones. The natural 

 enemies reared were five species of chalcids and one cecidomyid. The indications 

 are that the weevils are not able to emerge when plowed under or covered 

 with soil during cultivation. 



" Since the weevils hibernate within the fields, the one-crop system will pre- 

 vent severe injury. Badly infested fields should be plowed under immediately 

 after the berries are picked. Where the two-crop system is practiced the beds 

 should be burned over and thoroughly cultivated. Old, neglected patches should 

 not be tolerated. The weevil will probably not be serious on the Everbearing 

 strawberry. Covering the beds with muslin or spraying with poisonous arsenl- 

 cals was not satisfactory." 



A 4-page bibliography is included.
