【摘要】 以含1%氟虫腈、植物淀粉、引诱物质及粘附剂等自制的红蚁净(Pyragne)粉剂,在室内测定红火蚁Solenopsis invicta Buren各虫态的毒力。结果显示:红蚁净粉剂对红火蚁工蚁LT50=20.106h、LT90=23.78h,对有翅繁殖蚁LT50=20.951h、LT90=25.64h;工蚁能将红蚁净传递给蛹和卵引起中毒死亡。更多还原

【Abstract】 The effect of the pesticide—powder of Pyragne in controlling adults and immature stages of red fire ants Solenopsis invicta Buren was investigated in the laboratory. Pyragne is composed of Fipronil,plant starch,attractants and adhesives. Results showed that LT_ 50 and LT_ 90 on workers by the powder of Pyragne with 0.1% Fipronil as the main constituent were 20.106 h and 23.78 h, on winged productive ants were 20.95 1 h and 25.64 h, respectively; and Pyragne could result in the death of ant pupae and eggs by the trophallaxis of workers.更多还原
