[目的]优化黄脊竹蝗引诱剂配方,更好地实现黄脊竹蝗的有效控制。[方法]配制不同的引诱剂,通过林间诱杀试验测定不同配方毒饵对黄脊竹蝗的诱杀效果。[结果]Na Cl 2%+NH_4HCO_3 10%+Indole 5‰配方所制成毒饵诱杀黄脊竹蝗效果最好,24 h内的诱杀量可达639.4±48.14头·诱捕器-1,其次是2%Na Cl+10%NH_4HCO_3 配方,平均诱杀量达580.8±40.36头·诱捕器-1,与发酵人尿的诱杀量差异不显著(P〉0.05),应用时间显著影响各配方的诱杀效果。Na Cl和NH_4HCO_3 是人尿引诱黄脊竹蝗的关键物质,挥发物Indole对诱杀具有增效作用。[结论]应用人工配制的引诱剂诱杀黄脊竹蝗能显著降低林间成虫的种群数量,且能杀死大量雌虫,可用于林间黄脊竹蝗防治。
[Objective]To develop effective toxic attractants for the control of yellow-spined bamboo locust,Ceracris kiangsu. [Methods]The attractants for C. kiangsu adults were examined by field screening,and the effects of various toxic attractant baits were tested in bamboo forest of Hu'nan Province. [Results]The attractant,NaCl 2% +NH_4HCO_3 10% + Indole 5‰( 639. 4 ± 48. 14 adults killed per bait) was the most effective to kill C. kiangsu adults among all the attractants tested,followed by NaCl 2% + NH_4HCO_310%( 580. 8 ± 40. 36 adults killed per bait). The trapping effect of different attractants was influenced significantly by the duration of application in field.Sodium chloride and ammonium bicarbonate were the key chemicals attracting C. kiangsu adults,and Indole could enhance the attractiveness of the attractants. [Conclusion]Trapping and killing C. kiangsu adults with the attractants blended with different chemicals and toxic pesticide could decrease the population of the yellow-spined bamboo locusts,and the number of females killed was much more than the number of males.
