abstract
The insect order Lepidoptera is one of the most important insect orders in terms of both species and agriculture point of view. Majority of these are the serious pest of most agricultural crops. Insects-pests are mostly management by using insecticides which are not only ineffective but also resulted in environmental pollution and diseases’ outbreak. All these problems solution lies on the implementation of best IPM package. Biological control is one of the best options of Integrated Pest Management. Utilization of bio agent can easily be combined with other management techniques for having best IPM package. Parasitoids in this connection play a very important role in their management. These parasitoids attack the egg, larval or pupal stages of the host insects. In the present review the importance of parasitoids in controlling the different lepidopteron pests was discussed. The two major insect parasitoids orders hymenoptera with four families namely braconidae, ichneumonidae, chalcidae and trichogrammatidae and diptera with one family namely tachinidae in relation to biocontrol of selected lepidopteron pests have been studied. In addition the role of plant volatiles that play an important role in searching and locating their host and effect of temperature on the parasitoid performance has also been reviewed.
