3-甲基吲哚（粪臭素）是一种在实验室试验中显示为致倦库蚊产卵引诱剂/刺激剂的化合物，其被评价为对野外自然蚊子种群的作用。在实验中使用成对的黑色塑料桶，含有水处理的引诱剂溶液含有3-甲基吲哚，4-甲基苯酚，4-乙基苯酚，苯酚和吲哚的混合物或仅含有自来水，引诱剂诱饵陷阱收到显着更多的Cx。与未经处理的自来水相比，致倦鸡卵排的存活率更高。用引诱剂溶液诱捕的妊娠雌性诱捕器收集到的Cx显着更多。quinquefasciatus女性比陷阱只含有自来水。Cx的数量无显著差异。与仅含有3-甲基吲哚的水的诱捕器相比，在用引诱剂溶液诱捕的诱捕器中收集的致倦犬，表明3-甲基吲哚单独负责引诱。在实验池塘中进行的重复实验中，用3-甲基吲哚处理的池塘收到了显着更多的Cx。quinquefasciatus，Cx. tarsalis和Cx.比未经处理的池塘。用0.12和0.6 mg/L的3-甲基吲哚处理的实验池塘对产卵的Cx具有同样的吸引力。致倦肌这是首次发现3-甲基吲哚对Cx具有引诱/刺激作用。stigmatosoma和Cx.在野外或实验室条件下的跗跖。
3-Methylindole (skatole), a compound shown to be an oviposition attractant/stimulant for Culex quinquefasciatus in laboratory tests, was evaluated against natural populations of mosquitoes in the field. In experiments using paired black plastic tubs that contained water treated with an attractant solution containing a mixture of 3-methylindole, 4-methylphenol, 4-ethylphenol, phenol, and indole or that contained only tap water, the attractant-baited traps received significantly more Cx. quinquefasciatus egg rafts than did the untreated tap water. Gravid female traps that were baited with attractant solution collected significantly more Cx. quinquefasciatus females than did traps containing only tap water. There was no significant difference in number of Cx. quinquefasciatus collected in the traps baited with the attractant solution compared to the traps that contained water with 3-methylindole alone, indicating that 3-methylindole was solely responsible for the attraction. In replicated experiments conducted in experimental ponds, ponds that were treated with 3-methylindole received significantly more Cx. quinquefasciatus, Cx. tarsalis, and Cx. stigmatosoma egg rafts than did untreated ponds. Experimental ponds treated with 3-methylindole at two levels (0.12 and 0.6 mg/liter) were equally attractive to ovipositing Cx. quinquefasciatus. This is the first record of 3-methylindole showing attractancy/stimulation to ovipositing Cx. stigmatosoma and Cx. tarsalis under field or laboratory conditions.
