MONOTERPENE OVIPOSITION DETERRENTS FOR CABBAGE MAGGOTS, DELIA RADICUM (L.) (DIPTERA: ANTHOMYIIDAE)

Extract
The cabbage maggot, Delia radicum (L.), is a major root-infesting pest of cruciferous crops (Davidson and Lyon 1979). Current control methods include soil drenches with fensulfothion, carbofuran, and chlopyrifos (Matthews-Geringer and Hough-Goldstein 1988). Partial deterrency of oviposition by cabbage maggots was achieved using turpentinesoaked stakes (Havukkala 1982), and 3,5-dimethoxy-4-hydroxycinnamica cid, produced in the frass of a lepidopteran pest of cabbage (Jones et al. 1988). A blend of three monoterpenes (3-carene, limonene, and p-cymene) was found by Ntiamoah et al. (1996) to be the major oviposition deterrent for the onion maggot, Delia antiqua (Meigen), in a commercial pine oil, Norpine 65 (Northwest Petrochemicals, Annacortes, Washington). Our objectives were to evaluate this blend, and a more complex blend containing three additional constituents, as oviposition deterrents in the laboratory for the cabbage maggot.
