Study on host acceptance behavior of Tetrastichus nigricoxae Yang(Hymenoptera:Eulophidae)

Threshold temperature and effective accumulated temperature of Tetrastichus septentrionalis;

A new species, Tetrastichus septentrionalis sp.

Experiment of Developmental Threshold Temperature and Effective Accumulated Temperature of Chouioia cunea;

Safety Testing of Dimilin Ⅲ on Chouioia cunea;

Forest Releasing Techniques of Chouioia cunea;

Artificial Breeding of Chouioia cunea Yang with Tussah Pupa;

Chouioia cunea Yang,an extensively applied natural enemy,is the important parasitoid of Hyphantria cunea.

It was revealed by internal anatomy that the female of Chouioia cunea Yang has a pair of ovaries.

Ability of host discrimination and interspecific competition of Oomyzus sokolowskii (Kurdjumov).;

Interspecific interactions between Cotesia plutellae and Oomyzus sokolowskii,two major parasitoids of diamondback moth,Plutella xylostella;

Interspecific Competition Between Two Parasitoids Diadegma semiclausum and Oomyzus sokolowskii in Plutella xylostella;

, the control effectiveness of Trichogramma confusum, Oomyzus sokolowsakii and Cotesia plutellae on DBM were simulated and evaluated by using state space equation and addition analysis method of population control.
