摘要: 为提升蝉拟青霉对扶桑绵粉蚧的防治效果,本研究将其与6种不同类型的农药进行混配,系统评估菌药混用的相容性及其协同增效性。结果表明,苦参碱、呋虫胺和烯啶虫胺在稀释浓度下对蝉拟青霉孢子萌发具有促进作用。六种供试农药对蝉拟青霉菌落生长均有抑制作用,但其抑制作用随浓度的降低而减弱。呋虫胺稀释10倍后对蝉拟青霉菌产孢促进作用最显著。综上,烟碱类杀虫剂呋虫胺与蝉拟青霉具有较好的相容性。除松脂酸钠外,稀释5倍或10倍的苦参碱、印楝素、呋虫胺、烯啶虫胺及高效氯氰菊酯与蝉拟青霉孢子悬浮液联用均表现出增效或相加作用。蝉拟青霉与稀释10倍的呋虫胺或稀释5倍的苦参碱混用可显著增强对扶桑绵粉蚧的防治效果,同时有效减少农药用量,对农业生产实践具有重要的指导意义。

Abstract: To enhance the control efficiency of Paecilomyces cicadae against Phenacoccus solenopsis, P. cicadae combined with six different pesticides were systematically evaluated for compatibility and synergistic effects. The results showed that matrine, dinotefuran, and nitenpyram at diluted concentrations promoted the spore germination of P. cicadae. All six tested pesticides inhibited the colony growth of P. cicadae, but this inhibitory effect weakened as the concentration decreased. Dinotefuran at a 10-fold dilution exhibited the most significant promotion effect on the sporulation of P. cicadae, indicating the neonicotinoid insecticide dinotefuran of best compatibility with P. cicadae. Except for sodium pimaric acid, the combination of P. cicadae with 5-fold or 10-fold diluted matrine, azadirachtin, dinotefuran, nitenpyram, and beta-cypermethrin all showed synergistic or additive effects. The mixture of P. cicadae and 10-fold diluted dinotefuran or 5-fold diluted matrine significantly enhanced the control efficiency against P. solenopsis while effectively reducing pesticide use, providing important guidance for agricultural practical production.
