Abstract The ectoparasitoids, Cirrospilus ingenuus and Pnigalio sp. approved to be the main mortality factor on Phyllocnistis citrella populations. So, it could be used in IPM program for this pest. The entomopathogenic bacterium Bacillus sp. promise to be a good biological control agent against the tested pest (CLM). The host plant had an effective role on the predators (Chrysoperla carnea and Orius sp.) searching characteristics. Estimation of parasitoid percentage as parasitized hosts % gave an accurate value to CLM parasitoid activity. For the success of IPM program it is essential to know several information concerning the biology of the pest and their natural enemies such as net reproductive rate (Ro), mean generation time (T) and the intrinsic rate of natural increase(rm). |
