Studies on Host Finding by Parasitic Wasps

寄生蜂的寻找寄主行为包括6个步骤：1.羽化后的随机运动；2.羽化后的随机运动；在寄主昆虫栖息地的搜寻，III。寄主昆虫识别，iv。寄主昆虫孵化，V.寄主昆虫接受VI。产卵。我们的研究主要是在第二步和第三步中进行的。它们分别是介壳虫Ceroplastes rubens和天牛APhytis yanonensis产卵刺激物的鉴定，以及刺激物对褐飞虱寻找寄主行为的刺激，寄主植物的挥发物也刺激了寄主寻找行为。被寄主昆虫侵染的植物比未被寄生的植物更能吸引寄生蜂。粘虫幼虫上的产卵刺激剂必须通过人工介质和产卵膜来研究。由于凯隆酮喷雾到粘虫栖息地提高了粘虫的寄生率，将利它隆用于害虫管理是近期的一个重要课题。

The host-finding behavior by parasitoid wasps consists of the following 6 steps: i. Random movement after emergence, ii. Searhing in host insect habitat, iii. Host insect recognition, iv. Host insect foinding, v. Host insect acceptance vi. Oviposition. Our research mainly conducted in the study of the steps ii and iii. They are identification of oviposition stimulants in scale insects, Ceroplastes rubens and Aphytis yanonensis and stimulants in host searching behavior of Apanteles kariyai.Host searching behavior is also stimulated with volatiles from the host plants of the host insects. The infested plants by host insects attract parasitoid wasps more than uninfested plants.Oviposition stimulants present on the armyworm larvae have to be studied through artificial media and membranes for oviposition.Kairomone use in insect pest management is an important subject in the near future as the kairomone spray to armyworm habitate raised parasitization rate of Apanteles kariyai.
