ANAPHES SORDIDATUS (GIRAULT) (HYMENOPTERA: MYMARIDAE), AN EGG PARASITE OF THE CARROT WEEVIL, LISTRONOTUS OREGONENSIS (LE CONTE)

Abstract

The carrot weevil, Listronotus oregonensis (Le Conte), is an important pest of carrot and celery in eastern Canada (Stevenson 1985). In Quebec, it is univoltine and overwinters as adults (Boivin 1985). At present, the only way to control this pest is with chemical insecticides applied either as granules at seeding time to control the larvae or as foliar sprays to control the adults before they start to oviposit. If integrated pest management (IPM) programs are to be applied to crops attacked by the carrot weevil, additional control methods are needed.
