摘要: Laboratory and greenhouse studies were conducted on Oomyzus sokolowskii Kurdjumov, a parasite of the crucifer pest Plutella xylostella ( L.). O. preferred 3rd 4th instar P. larvae over fresh pupae for parasitization. It is thus larval parasite. Within range 10‡C to 35‡C, parasitism was positively correlated with temperature. High at temperatures 30‡C 35‡C indicates that this insect suitable control in tropical lowlands. In no- choice test where only Cotesia plutellae another potentially competing xylostella, offered, failed parasitize C. plutellae. parasitized larvae. This parasite, therefore, not hyperparasite xylostella. When plutellae-ovvposited offered intervals, sokolowskii, freshly oviposited host The longer period elapsed after oviposition larvae, lesser these by sokolowski.
