Studies On The Influence Of Exogenous Substances To Exorista Sorbillans And Ecological Control To Exorista Sorbillans

Exorista sorbillans Wiedemann,belong to Insecta, Diptera,Tachinidae, Exorista Meigen,.It Widely distributed.It's host range is Wide and higher parasitism."Mei Can Ying"is used to kill Exorista sorbillans in the Sericulture production from 1963. However, as a result of long-time using, Exorista sorbillans have had a resistance to"Mie Can Ying". It's Control effect has been decreasing, causing environmental pollution. Sustainable development requires us to develop biorational pesticides or environment acceptable pesticides, and develop integrated pest management. Therefore, to find ecological control control methods is urgently needed.In particular, it's profound significance in the agricultural forestry development that finding out insecticidal active material in the plant. The theory and methods of insect ecology and are used in this article. In the basis of summing up the results of previous studies, the researchs are carried out by taking laboratory research combined field survey, population of breeding flies and mathematical statistics method. In order to control Exorista sorbillans in the sericulture and control farming and forestry pests using Exorista sorbillans,the research about relations of Exorista sorbillans,host bombyx mori,bombyx mori exterior ecological factor, attraction and oviposition deterrence of exogenous substance on Exorista sorbillans and the effect of"Mie Can Ying"affecting Exorista sorbillans are carried out.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): study the parasitic behavior influence of host conditions on the Exorista sorbillans. The third part (Chapter 3 to Chapter 4): study and investigate attraction and oviposition deterrence of exogenous substance on Exorista sorbillans. The fourth part (Chapter 5) discuss killing effect of fly control material - "Mie Can Ying" on the Exorista sorbillans. The fifth part (Chapter 6 to Chapter 7) study the ecological control methods of Exorista sorbillans , detailed analyse the research results, made conclusions and future studies.Preliminary findings show that: Host conditions have some effect on the parasitic behavior of Exorista sorbillans; Sweet orange oils, tulip oils and honey have strong attraction on Exorista sorbillans adult flies; Allium sativum has strong oviposition deterrence on Exorista sorbillans adult flies; Silkworm has a strong antidote capacity to " Mie Can Ying", so it become the umbrella of resisting "Mie Can Ying" to Exorista sorbillans.
