4.Abstract: Based on an investigation about the naturalenemy biological resources current situation was made at Qufu Konglin,and some concrete measures for the rational development,usage and protection of naturalenemy biological resources was set forth.
5.Through investigating,plant feeding habits pests surpassing the naturalenemy insect far away in quantity. The relative fecundity of the pests and enemies is 10.19% and 1.38% respectively.
6.Anagyrus daclylopii (Howard) belongs to family Encyrtidae (Hymenoptera: Chcidoidae). It is an important endoparasitic naturalenemy of Nipaecoccus vastator (Maskell) by means of mono-parasitic or multiparasitic ways.
7.The species of naturalenemy was quite abundance,which included 7 orders,15 families and 24 species. There were 12 species of spiders in the organic litchi orchard.
8.Neodiprion sertifer Geoffroy could be controlled by its naturalenemy Misumena tricuspidata Fabricius and Araneo ventricosa L. Koch which could eat 50—90 and 90—120 espectively.
9.Key Factors Affecting Long-term Forecast of lst Asian Cosrn Borer(Ostrinia nubilalis)Emergency Size in Jiling Province──Ⅰ. Relation of Emergency Size with NaturalEnemy and Overwinter Population Size
10.Paederus Fuscipes Curtis is the naturalenemy of Agricultural and Forestrial pest insects and feeds on them. 2～3 generations of it are produced in Anhui Province every year.
