Greenhouse and field evaluations of entomopathogenic nematodes (Nematoda:Heterorhabditidae and Steinernematidae) for control of cabbage maggot (Diptera:Anthomyiidae) on cabbage.

Entomopathogenic nematodes--Heterorhabditis bacteriophora Poinar (Oswego strain), Steinernema carpocapsae (Weiser) (NY001 strain), Steinernema carpocapsae (25 strain), Steinernema feltiae Filipjev (= Neoaplectana carpocapsae Weiser) (369 strain), Steinernema feltiae (27 strain), and Steinernema riobravus Cabanillas and Poinar (355 strain)--were examined for pathogenicity against cabbage maggot, Delia radicum (L.), larvae in the greenhouse and field. Applications (per plant) of 3,000 and 4,000 infective juveniles of S.
