Exorista sorbillans Wiedemann,Insecta, Diptera,Tachinidae, Exorista Meigen, which is the complete metamorphosis insect, and a larval parasitoid of Bombyx mori silkworm and other defoliators."meicanying"is used to kill Exorista sorbillans in the Sericulture production. However, as a result of long-time using, Exorista sorbillans have had a resistance to ."miecanying". Therefore, to find new drugs and new control methods is urgently needed. To carry out control research of new technologies, we must first fully understand the ecological factors and the related ecological conditions during the ujifly growing and developmenting, and master the parasitism regularity. In the basis of summing up the results of previous studies, the research about Exorista sorbillans ecological factors and parasitic behavior are carried out by taking production site investigation, rearing Exorista sorbillans in the Laboratory and doing ecological experiment . The theory and methods of insect ecology and insect biology are used in this article.This article consists of four parts. The first part (Chapter 1): first clarify the purpose and significance, while introduce the relevant research progress, research methods at home and abroad, as well as innovation thesis. The second part (Chapter 2 to Chapter 5): study the influence of ecological conditions, including the light factor in the pupal stage, pupal stage in soil habitats, adult nutrition and adding exogenous substances "miecanying" to the growth and development of Exorista sorbillans. The third part (Chapter 6) to introduces the parasitic regularity and harm of Exorista sorbillans. The fourth part (Chapter 7 to Chapter 8) discuss the control methods of Exorista sorbillans , detailed analyse the research results, made conclusions and future studies.Preliminary findings show that: all the various ecological conditions above-mentioned could influence Exorista sorbillans during pupa stage, adult growth. Exorista sorbillans has been significant resistance to "miecanying", the indoor activities and parasitic behavior of Exorista sorbillans seems regularity. The results revealed that a theoretical basis and experimental evidence for control Exorista sorbillans.
