不同植物浸液对白纹伊蚊的产卵引诱作用

应用孕卵蚊虫粘捕法现场测试不同植物浸液对白纹伊蚊Aedes albopictus(Skuse)的产卵引诱作用,发现樟树叶、黄杨叶、狗尾草、绊根草、玉兰叶和竹叶的浸液现场诱蚊效果与自来水对照没有显著的差异;竹叶、玉兰叶、狗尾草和绊根草室内发酵21、30和45d的现场诱蚊效果没有显著的差异,而应用诱卵器法显示:竹叶、玉兰、狗尾草、绊根草植物浸液和自来水对照的诱卵数却差异显著。现场试验发现自来水、室外积水和蚊虫饲养水对白纹伊蚊的引诱效果没有显著的差异。

Oviposition responses of Aedes albopictus to the organic infusions from several plants

Responses of Aedes albopictus (Skuse)females to the organic infusions from several plants were evaluated with sticky ovi-traps in the field. No significant difference in the mean number of A. albopictus collected was found between the sticky ovitrap baited with the organic infusions from camphor leaf, boxtree leaf, green bristle grass leaf, Bermuda grass, Magnolia grandiflora leaf, and bamboo leaf, and that with tap water. The organic infusions from bamboo leaf, Magnolia grandiflora leaf, green bristle grass and Bermuda grass fermented for 21 days or 30 days or 45 days showed no significant difference. When eggs collecting traps were used, significant differences were found between the organic infusions and the dilutions from bamboo leaf, Magnolia grandiflora leaf, green bristle grass and Bermuda grass, and that from tap water. There was no significant difference among tap water, standing water outdoors, and larvae rearing water.
