Quantitative exploration of population differentiation will benefit the utilization and improvement of wasp breeding; in-depth studies on the capability of avoiding superparasitism, host selection and adaptability of Trichogramma populations collected from different localities and hosts can produce some conclusions significant to Trichogramma application; studies on ovipositional behaviors are important for breeding improvement; co-parasitism is a common behavior among egg-parasitoids, and also an important factor affecting artificial rearing and field release; observations on inter-specific competition are helpful for choosing the most competitive natural enemies. This dissertation treated of the pragmatic aspects of the diagnostic system, i.
