| Abstract: | Results of the field studies conducted in two counties of Shaanxi Province during 1988 to 1989 revealed differences in parasitization of imported cabbage worm, Pieris rapae by different species or strains of Trichogramma. Among two species, Trichogramma evanescens and T. chilonis arid different strains of the former, three strains of T. evanescens (LG-46, DH-9, and DG-11) produced egg parasitization of over 63%, which was significantly higher than that by other strains of the species and by T. chilonis. |
