摘要
黑肾卷裙夜蛾Plecoptera oculata Moore是我国南方珍贵树种降香黄檀Dalbergia odorifera种植区的一种食叶性害虫。【目的】初步研究黑肾卷裙夜蛾的形态特征、生物学特性以及生活史等问题。【方法】通过室内观察和野外调查,数据精确测量与统计,总结与分析了黑肾卷裙夜蛾的形态、生物学特性等问题。【结果】黑肾卷裙夜蛾幼虫6龄,黑肾卷裙夜蛾一个世代发育需要（41.64±1.59）d,越冬代约为120 d,室内饲养存活率为61.37%±0.80%,其中卵发育历期（7.53±0.40）d,孵化率为（86.67%±1.43）%,幼虫发育历期为（18.42±0.41）d,存活率为61.30%±1.21%,蛹期为（8.67±0.58）d,羽化率为75.55%±1.14%,成虫寿命为（7.02±0.78）d,存活率为74.44%±1.12%,该虫在广东地区一年发生可以发生7~8代,且具有世代重叠现象。【结论】通过了解该虫的生物学特性,为切实可行的防控黑肾卷裙夜蛾提供理论依据。
Plecoptera oculata Moore is a serious defoliator of Dalbergia odorifera forests. ]Objectives] To investigate the morphology, biological characteristics and life cycle ofP oculata. [Methods] Laboratory observation and field investigation. [Results] The larvae of P oculata had 6 instars. The duration of a whole generation was （41.64±1.59）d, and the over-wintering stage lasted three months. The egg stage lasted for （7.53±0.40）d, and the ratio of egg fertility was about 86.67%±1.43%. The larval stage lasted for （18.42±0.41）d and the pupal stage （8.67±0.58）d. The life span of adults was （7.02±0.78）d. There are 7 or 8 generations per year in Guangdong and generations overlap. [Conclusion] Biological characteristics ofP oculata provide both a practical and theoretical basis for the control and prevention of this pest.
