本文测定了7种常用化学杀虫剂高效氯氰菊酯、高氯甲维盐、辛硫磷、高效氯氟氰菊酯、阿维菌素、阿维杀虫单、虫酰肼对球孢白僵菌TST05菌株菌丝生长及孢子萌发、生长及产孢的影响,以研究化学药剂与球孢白僵菌TST05菌株的相容性,为化学杀虫剂和白僵菌制剂混合应用提供依据。结果表明,在田间常用浓度下,7种杀虫剂对该菌株的菌丝生长抑制率为27.93%～38.74%。虫酰肼组的孢子萌发率为33.19%,几乎不形成菌落,产孢量仅为0.05×106个/mL;而其余6种杀虫剂组的孢子萌发率为50.34%～70.62%,能形成较致密的菌落,产孢量为(2.51～3.58)×106个/mL。杀虫剂对该菌株的抑制作用随着浓度的降低而减小,田间浓度再稀释5倍后,各处理组孢子萌发率升高到72.08%～84.92%;产孢量为(3.01～9.61)×106个/mL。在田间浓度下,虫酰肼与该菌株不相容;其余6种杀虫剂的相容性较好。并且相容性随着杀虫剂浓度的降低而提高。
In this paper, the determination of seven commonly used chemical insecticide beta-cypermethrin, metoclopramide, phoxim, lambda-cyhalothrin, avermectin, Avian insecticide, tebufenozide Beauveria bassiana TST05 strain mycelial growth and spore germination, growth and sporulation in order to study the chemical compatibility with Beauveria bassiana TST05 strains compatibility for chemical pesticides and Beauveria bassiana formulations provide a basis for mixed applications. The results showed that the mycelial growth inhibition rate of the seven insecticides against the strain was 27.93% ~ 38.74% under the common concentrations in the field. The spore germination rate was 33.19% in the tebufenozide group, almost no colonies were formed, and the sporulation rate was only 0.05 × 106 / mL. The spore germination rate was 50.34% ~ 70.62% in the other six pesticide groups, which could form More dense colonies, sporulation volume (2.51 ~ 3.58) × 106 / mL. The inhibitory effect of insecticides on the strain decreased with the decrease of concentration. After spore dilution was further increased by 5 times in the field, the spore germination rate increased to 72.08% -84.92% in each treatment group. The sporulation amount was (3.01 ~ 9.61) × 106 / mL. In the field concentration, tebufenozide and the strain is incompatible; the other six insecticides compatibility better. And the compatibility increases with decreasing insecticide concentration.
