Pupa- parasitoid

Study on conservation and application of beneficial insects is one of the most important approach in the biological control, which is considered by many to be the most important phase of applied control to redue a pest's populations and avoidance a toxicity of pesticides. The Ichneumon wasps are one of the most important parasitic species in the role to regulate number of pest's populations belong to scale caterpillar (Lepidoptera)(Kasparyan, 1981). One of them, a large part belong to subfamily Ichneumoninae, tribe Pimplini etc. are specially parasite the pupa of caterpillars. There were some of the pupa-parasited ichneumon wasps have been studied and applied effectively in the insect pests control (Weseloh, Anderson, 1982; Guerdoux, 1982; Greenblatt, Barbosa, 1982 etc.). At present (1990) the system of Ichneumon wasps (Ichneumonidae) is not completed reason by a numerous species of it (Kasparyan, 1981). Several model (Laurence , 1988, Lotka ,1932, Nicholson&, Baily ,1935, Watt. 1959,Watt.1961) have described the relationships between parasites and their host, one of them is Thompson's predator- prey model (Varley, Gradual,Hassell. 1978, ).
