吡虫啉与蝉拟青霉的相容性及增效作用研究
Compatibility of Imidacloprid and Paecilomyces cicadae and Synergism against Aphids
摘要
Abstract
The effects of imidacloprid on colony growth, conidial sporulation and germination of Paecilomyces cicadae were tested. The results showed that the lethal dose (1:3 000) imidacloprid inhibited mycelium growth and sporulation to a certain degree,but the sublethal dose (1 : 15 000) and low sublethal dose (1:30 000) of imidacloprid had no apparent effect on mycelium growth,conidial sporulation and germination. Their inhibition rates were 2. 53% and 0. 73% on colony growth,and 1. 02% and -0. 35% on conidial germination. These indicated that the sublethal dose and low sublethal dose of imidacloprid had compatibility with P. Cicadae. The result of a bioassay showed obvious synergism against aphids when P. Cicadae was mixed with the sublethal dose and low sublethal dose of imidacloprid, with LT50 0. 37 days and 0. 26 days earlier and the corrected mortality rate higher than that of P. Cicadae alone.关键词
