An evaluation of several insecticides, namely, 0.01% fipronil, 0.05% indoxacarb, and 2% boric acid in liquid bait formulations were carried out against field populations of the longlegged ant, Anoplolepis gracilipes (Fr. Smith) (Hymenoptera: Formicidae). The baits were formulated in brown cane sugar solution (50%, wt:wt) and placed in an experimental bait station. Each bait was evaluated against populations of A. gracilipes at four buildings. Fipronil, indoxacarb, and boric acid were effective against A. gracilipes, with > 90% reduction of workers within 3 d posttreatment. Total reduction (100%) was achieved within 7 d for fipronil, 14 d for indoxacarb, and 56 d for boric acid. The performance of fipronil and indoxacarb baits did not differ significantly (P > 0.05) in all postbaiting sampling intervals. Reduction of A. gracilipes resulted in an increase in other ant species [Monomorium pharaonis (L.), Monomorium floricola (Jerdon), Monomorium orientale Mayr, Monomorium destructor (Jerdon), Tapinoma indicum Forel, Pheidole sp., and Camponotus sp.] at the baited locations.
对几种杀虫剂进行了评估，即0.01%氟虫腈、0.05%茚虫威和2%硼酸的液体诱饵制剂，用于防治长足蚁（Anoplolepis gracilipes (Fr. Smith)，膜翅目：蚁科）的野外种群。诱饵制剂于红糖溶液（50%，重量比）中，并放置在实验诱饵站中。每种诱饵在四栋建筑物中针对长足蚁种群进行了评估。氟虫腈、茚虫威和硼酸对长足蚁有效，处理后3天内工蚁数量减少>90%。氟虫腈在7天内实现了完全减少（100%），茚虫威在14天内实现了完全减少，硼酸在56天内实现了完全减少。在所有诱饵投放后的采样间隔中，氟虫腈和茚虫威诱饵的效果没有显著差异（P>0.05）。长足蚁数量的减少导致诱饵投放地点其他蚂蚁物种[法老小家蚁（Monomorium pharaonis (L.)）、花翅小家蚁（Monomorium floricola (Jerdon)）、东方小家蚁（Monomorium orientale Mayr）、破坏小家蚁（Monomorium destructor (Jerdon)）、印度扁胸切叶蚁（Tapinoma indicum Forel）、大头蚁属（Pheidole sp.）和弓背蚁属（Camponotus sp.）]数量增加。
