黄色光对黏虫成虫产卵和寿命的影响

摘要

The effects of yellow light on the oviposition and adult longevity of Mythimna separata were investiga-ted indoors.The results showed that the pre-oviposition period of M.separata exposed to yellow light was pro-longed 1.2 d (P = 0.002)and the oviposition quantity reduced 27% (P = 0.001).Meanwhile,the longevity of M.separata treated in continuous yellow light was prolonged 2.3 d.This study showed that exposure of yellow light at night had some effect on the biological habit of M.separata .%室内条件下研究黄色光源对黏虫成虫产卵和寿命的影响。结果表明，夜间施加黄色光照射能够使黏虫的产卵前期延长1．2 d （P＝0．002），产卵量减少27％（P ＝0．001），成虫寿命延长2．3 d。可见，夜间施加黄色光照射对黏虫成虫的生物学习性有一定的影响。
