摘  要：
【背景】椰子织蛾是新入侵我国海南岛的棕榈害虫,昆虫不育技术是控制该害虫的潜在措施。【方法】通过研究椰子织蛾生殖、发育、存活等特性,探讨椰子织蛾不育技术的生物学基础。【结果】在(28±2)℃、(70±10)%RH、以椰子老叶饲养的条件下,每雌产卵量约170粒,净增值率约55.4,倍增时间约9.6 d,表明椰子织蛾可在室内大量饲养,为辐射不育提供虫源。椰子织蛾雌雄比为1∶1.04,雄虫先熟,产卵前期短,产卵期集中,表明该害虫交配行为相对简单,有利于不育雄虫发挥效能。雌蛹显著重于雄蛹,有利于不育过程中雌雄虫的分离。发育起点温度11.5℃,有效积温996.9日度,在海南岛每年发生4~5代,这些数据可用来预测椰子织蛾种群动态,便于释放不育雄虫。【结论与意义】本研究从生物学角度表明椰子织蛾可用昆虫不育技术进行防控,为其进一步的不育技术研发提供相关信息。

摘  要：
【Background】The coconut black-headed caterpillar,Opisina arenosella Walker,is one of the significant pests of palm plants. We investigated the biological basis for the sterile insect technique( SIT) of O. arenosella as a potential measure to control this pest. 【Method】O. arenosella fecundity,development and survival rates were studied under controlled conditions of( 28±2) ℃and( 70±10) % relative humidity and fed with mature coconut Cocos nucifera leaves. 【Result】During the experiment,O. arenosella laid about 170 eggs per female,with a net reproductive rate of 55.4,and doubling time of 9.6 days. These results indicated that O.arenosella could be massively reared in lab conditions,hence become an insect resource for SIT. O. arenosella exhibited protandry with sex ratio of 1 ∶ 1. 04. Preoviposition and oviposition were short indicating that mating might be simple,thus facilitating male sterilisation. Female pupa was larger than male,which was helpful to separate male and female during SIT. The estimated developmental threshold temperature was 11.5 ℃,and estimated effective accumulated temperature was 996.9 degree days. The predicted number of generations per year in Hainan was 4 ~ 5. This ecological information provided more realistic estimates of O. arenosella population and sterile moth ratios needed for desired levels of control.【Conclusion and significance】This paper showed the potential for SIT of O. arenosella and provided information for further development of a SIT program.
