| Abstract: | This paper used the method of main factor analysis to analysis the complex ecosystem of leafminers Liriomyza and natural enemies in the field of broad bean as an example. And this method was used to identify the insect populations of effecting complex ecosystem.And evaluation functions were established to compare the complex system in each period.These results could guide the management of pest Liriomyza. |
