| 摘 要： | 目的]探明非寄主植物挥发物对井上蛀果斑螟成虫寿命和繁殖力的影响,为该虫的综合治理提供科学依据.方法]在实验室条件下,选择八角、花椒、生姜、小米辣、薄荷和草果等6种井上蛀果斑螟非寄主芳香植物,采用生物测定法研究不同非寄主植物挥发物对井上蛀果斑螟成虫寿命、产卵前期、产卵期、产卵量和卵孵化率等生物学指标的影响.结果]6种非寄主植物挥发物对井上蛀果斑螟成虫的寿命和繁殖力有显著影响(P<0.05,下同).小米辣挥发物对井上蛀果斑螟的产卵前期影响最大,产卵前期较对照(1.03 d)延长2.03 d;八角挥发物对井上蛀果斑螟的产卵期影响最大,产卵期较对照(9.20 d)缩短6.62 d;八角挥发物对井上蛀果斑螟雌、雄成虫的寿命影响最大,八角挥发物处理下雌、雄成虫寿命仅为4.79和6.02 d,较对照分别减少11.64和8.79 d.八角挥发物处理下井上蛀果斑螟成虫无产卵高峰期出现,其余处理产卵高峰期仅为1d.各处理单雌平均日产卵量均显著下降.八角挥发物处理的单雌平均产卵量和子代卵的孵化率最低,产卵抑制率达86.21%,子代卵孵化率较对照减少83.19%.结论]八角挥发物对井上蛀果斑螟成虫寿命和繁殖力有较强的抑制作用,可用于针对该虫的生态控制和植物源农药开发研究.

| Abstract: | Objective]Effects of non-host plant volatiles on the longevity and fecundity of Assara inouei Yamanaka adults were studied to provide scientific basis for comprehensive control of the pest.Method]The effects of six non-host aromatic plant volatiles,such as Illicium verum,Zanthoxylum bungeanum,Capsicum frutescens,Zingiber officinale, Mentha haplocalyx and Amomum tsaoko,on longevity of adult,pre-oviposition period,oviposition period,number of eggs laid per female and egg hatching rate of A.inouei were observed respectively using bioassay methods under the labo-ratory conditions.Result]Volatiles of six non-host plants had significant inhibitory effects on longevity and fecundity of A.inouei(P<0.05,the same below).The volatiles of C.frutescens showed the maximum impact on the adult at pre-ovipo-sition period,pre-oviposition period was 2.03 d longer than that of the control(1.03 d).The volatiles of I.verum showed the maximum impact on oviposition period,and the oviposition period was shortened by 6.62 d compared with the control (9.20 d).I.verum volatiles had the largest effects on longevity of male and female adults.The longevity of female and male adults under such treatment was only 4.79 and 6.02 d respectively,which was shortened by 11.64 and 8.79 d respec-tively compared with the control.There was no peak oviposition period for female adults in I.verum volatiles treatment.In other treatments,the peak period only lasted 1 d.Average number of eggs laid per female per day in each treatment were significantly decreased compared with the control.Average number of eggs laid per female and egg hatching rate of off-spring were the lowest in I.verum volatiles treatment,the oviposition inhibition rate was 86.21%,and the egg hatching rate of the offspring decreased by 83.19% compared with the control.Conclusion]The volatiles of I.verum show strong inhibitory effects on longevity and fecundity of A.inouei adults,and it can be used for ecological control of the pest and development of plant-derived pesticides. |
