稻纵卷叶螟对不同植物的产卵趋性与取食选择
Oviposition and Feeding Preference of Cnaphalocrocis medinalis (Guenée) for Four Different Plants
摘要
Abstract
[Objective]The rice leaffolder(RLF) [Cnaphalocrocis medinalis (Guenée)] is a kind of pests that bring serious harm to rice. The RLF can complete life cycle on a variety of gramineous plants, but almost only exclusively in rice in the field even in the outbreak years. Our aim is to recover the mechanism of oviposition and feeding preference of the RLF for rice and other host plants.[Method]We compared the oviposition and feeding preference of the RLF for four different plants: Zea mays L., Oryza sativa L., Echinochloa crus-galli (L.) Beauv and Setaria glauca (L.) Beauv. We also analyzed the influence of feeding experience on oviposition preference. [Result]The results showed that the female adults of the RLF have obvious oviposition preference, 49.08% of eggs were laid on rice in rearing cages, significantly higher than other plants. The development duration of larvae fed on rice was 17.29d, significantly shorter than that on Zea mays and Setaria glauca. The oviposition preference of the female fed on rice and maize had no significant difference. The old larvae showed significant feeding preference. The feeding preference of the 3rd- and 4th-instar larvae fedon Oryza sativa followed the trend of Setaria glauca> Oryza sativa, Echinochloa crus-galli > Zea mays, while for the young larvae fed on Zea mays, the preference followed the tendency of Setaria glauca> Zea mays > Oryza sativa, Echinochloa crus-galli.[Conclusion]These results suggest that rice had the highest number of eggs, but the oviposition preference was not positively related to larval feeding selectivity. The larval growth and development was the best on rice, and the feeding experience may change the feeding preference of larvae partially.关键词
