椰子木蛾的产卵节律及其对寄主植物的产卵选择性
Oviposition rhythms of Opisina arenosella and its oviposition preferences on different host plants
摘要
Abstract
[Background] Opisina arenosella Walker is new invasive pest on palm plants that invaded China in recent years. Study on its oviposition can provide reference for monitoring and controlling this pest. [Method] The oviposition rhythms of O. arenosella fe-male adults and its oviposition preferences to different host plants were observed under indoor conditions. [Result] The highest daily fecundity was 34.4 eggs/individual, and most eggs were laid in the 4 days after adult emergence, accounting for 54.1% of the total number of eggs laid. Females mainly laid eggs at night, between 23:00 and 8:00. There were no significant differences in fecundity on host plants Cocos nucifera, Livistona chinensis, Roystonea regia, Areca catechu and Chrysalidocarpus lutescens, from 89.3 eggs/ind. to 147.7 eggs/ind. We detected differences on the preferred egg sites on various host plants. [Conclusion and significance] The adults of O. arenosella have a greater reproduction capacity and a stronger oviposition rhythms, and there is no obvious oviposition preference on different host plants.关键词
