We studied the effect of Trichogramma brassicae Bezdenko (Hymenoptera: Trichogrammatidae) parasitism of Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) eggs on the foraging behavior of Nabis pseudoferus Remane (Hemiptera: Nabidae) feeding on T. absoluta eggs of different ages. Older parasitized eggs (48–72 h old) were rejected after probing with the probosis. A separate experiment showed that probing did not harm developing parasitoids. Bugs greatly reduced their feeding times on older parasitized eggs and spent more time grooming and probing eggs and leaves. Predators exhibited a type III functional response to 24 h-old eggs, but a type II response to older eggs, whether parasitized or not. 24 h-old eggs suffered higher attack rates, and required less handling time than older eggs. Although the predatory efficiency of N. pseudoferus was reduced in the presence of parasitized eggs, the partial refuge enjoyed by T. brassicae in older eggs may permit an additive impact on the pest, and should facilitate the joint augmentation of both species against T. absoluta.

我们研究的影响赤眼蜂甘蓝Bezdenko（膜翅目：赤眼蜂科）的寄生番茄斑潜蝇蛾（鳞翅目：麦蛾科）上的觅食行为鸡蛋姬pseudoferus Remane（半翅目：Nabidae）喂养T. absoluta不同年龄的鸡蛋。探测到该病后，拒绝了较大的寄生卵（48-72 h）。一个单独的实验表明，探测并不会损害正在形成的寄生虫。虫子大大减少了对寄生虫卵的取食时间，并花费了更多的时间修饰和探测卵和叶。捕食者对24小时大的卵表现出III型功能性反应，但对年龄较大的卵表现出II型功能性反应，无论是否被寄生。与旧鸡蛋相比，24小时大的鸡蛋遭受更高的侵袭率，并且需要的处理时间更少。虽然N的掠夺效率。pseudoferus在寄生鸡蛋的存在下还原，部分避难所享有由T.甘蓝年龄较大的卵中的卵可以允许对害虫的累加影响，并应促进两种对付绝对黑穗病菌的联合繁殖。
