Abstract
The black vine weevil, Brachyrhinus sulcatus (F.), a parthenogenetic species, has been present as a minor pest of strawberry in the Pacific northwest for many years (Treherne, 1914; Downes, 1924; Wilcox, Mote and Childs, 1934). Recently Andison (1953) reported that the species has increased rapidly in numbers during the past several years. In this area B. sulcatus is now as important as, if not more important than, the serious pest of strawberry, the strawberry root weevil, Brachyrhinus ovatus (L.). Since most of the damage is done by the larvae, which feed on the strawberry roots, it is necessary to control the adults before they commence oviposition, especially on soils that have not been treated with insecticides. The adults emerge and feed on the strawberry foliage during the first week of harvest. Studies at the Victoria laboratory have shown that most or all of the crop is harvested before oviposition becomes general. Hence, an insecticide can be applied before oviposition becomes general if this date can be predicted by examining the reproductive system. Also, it is important to know the stage of development of the ovaries of those adults that overwinter and are found in the strawberry fields in late March and April, so that control measures can be applied before oviposition again becomes general.
