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。
Black Kidneys Volumeter Pteroptera oculata Moore is a leaf-eating pest in the Dalbergia odorifera plantation area, a valuable tree species in southern China. 【OBJECTIVE】 To study the morphological characteristics, biological characteristics and life history of Daphnia magna 【Method】 Through the indoor observation and field investigation, the data accurate measurement and statistics, the morphology, biological characteristics and other issues of the black kidney roll moth were summarized and analyzed. 【Result】 The results showed that the age of 6 generations of the black moth larvae of Spodoptera litura was 41.64 ± 1.59 days, and the survival rate of rearing indoors was 61.37% ± 0.80% The developmental duration was (7.53 ± 0.40) d, the hatching rate was (86.67% ± 1.43)%, the larvae developmental period was (18.42 ± 0.41) d, the survival rate was 61.30% ± 1.21% and the pupal stage was (8.67 ± 0.58) d, the emergence rate was 75.55% ± 1.14%, the adult life span was (7.02 ± 0.78) days and the survival rate was 74.44% ± 1.12%. The insect could occur in Guangdong area for 7-8 generations in one year, . 【Conclusion】 By understanding the biological characteristics of the insect, provide a theoretical basis for the practical prevention and treatment of black kidney roll moth.
