Effect of temperature on development and reproduction of Proprioseiopsis asetus (Acari: Phytoseiidae) fed on asparagus thrips, Thrips tabaci.

Thrips tabaci Lindeman (Thysanoptera: Thripidae) is one of the most important pests of asparagus in China. In this study the effects of five constant temperatures (15, 20, 25, 30 and 35 °C) on the growth, survivorship and reproduction of Proprioseiopsis asetus (Chant) (Acari: Phytoseiidae) fed on T. tabaci was examined under laboratory conditions.

[Control efficacy of Trichogramma japonicum against Chilo suppressalis and Chilaraea auricilia].

In order to understand the relationships of the population increase capacities between egg parasitoid Trichogramma japonicum Ashmead (Hymenoptera: Trichogrammatidae) and two rice borers Chilo suppressalis Walker and Chilaraea auricilia Dudgeon (Lepidoptera: Pyralidae), and to evaluate the control efficacy of T. japonicum against C. suppressalis and C.
