Abstract
Laboratory studies were conducted to determine the effects of three wheat cultivars, “Knox 62” “CaldwelI” and “Monon”, on the Hessian fly Mayetiola destructor (Say) and its parasitoid Platygaster hiemalis Forbes. The number of Hessian flies that survived from egg to flaxseed stage, the number of Hessian flies parasitized by P. hiemalis, and the average number of parasitoids produced within each parasitized pupa were used to determine the cultivar and the interaction effects on the Hessian fly as well as on the parasitoid. The fewest Hessian fly survived, and the smallest parasitism was found on Knox 62 and were significantly different from those on other cultivars. Results showed that a cultivar with highly antibiosis against the Hessian fly could also reduce the effectiveness of this parasitoid. However, resistant cultivars and parasitoid complemented each other in reducing the numbers of the Hessian fly.
室內測定Knox 62、Caldwell及Monon三種小麥品種與寄生蜂Platyaster hiemalis Forbes及二者之交感作用對小麥癭蚊存活數、被寄生數及自被寄生癭蚊蛹羽化之P. hiemaIis蜂數等之影響，結果顯示Knox 62品種上，癭蚊之存活率與被寄生率均最低且與其他品種者差異顯著，此說明具高度抗生作用之小麥品種可減低瘦蚊密度但亦能影響該種蜂之寄生效果，雖然如此，一般而言，抗蟲小麥品種與P. hiemalis寄生蜂二者可相輔相成，合力降低小麥癭蚊之族群密度。
