Abstract: This paper deals with the influence of the mixed biocide GCSC-BtA on the pupal and adult stages of Apanteles plutellae Kurd. (Hym., Braconidae) and its host, Plutella xylostella (L.) (Lep., Plutellidae). The results show that mortalities of the pupae of P. xylostella in the direct-dip bioassay were 84.67 %, that of the adults in the residue bioassay at 1.2500 mg/ml concentration of GCSC-BtA were 78.00 % which were significantly higher than the mortality values for the pupae with 54.62 % and adults with 48.13 % of A. plutellae. In contrast, cypermethrin showed extremely high toxicity to the pupae with 94.58 % and adults with 86.00 % mortality values of A. plutellae as compared to the low mortality values of 42.14 % for the pupae and 32.11 % for the adults of P. xylostella, with the same concentrations and bioassay methods. The LC50 values of GCSC-BtA were 0.3402, 0.5516 and 1.2405, 1.9480 mg/ml for the pupae and adults of P. xylostella and A. plutellae, respectively, while the LC50 values for cypermethrin were 1.5652, 2.3471 and 0.1096, 0.1152 mg/ml, respectively. GCSC-BtA was found more toxic to the pupae and adults of P. xylostella and safer to the pupae and adults of A. plutellae than cypermethrin. The possibilty of using GCSC-BtA against P. xylostella under partial control by A. plutellae in vegetable fields is discussed.
