查询词典 instar

Epicauta chinensis Laporte was raised in our lab and the results indicate that the adults like to eat the leaves of clover, soybean, sugar beet and potato. The best way to serving foods to the adults is inserting the plants into bottles full of water. While the larvae like eating the ovum dollops of L. migratoria manilensis and it will be easier for the first instar larvae to find and eat with top of the ovum dollops slightly out of soil.

室内人工养殖中华豆芫菁 Epicauta chinensis Laporte 的结果表明：成虫喜食苜蓿、大豆叶，也取食甜菜和马铃薯的叶；最适宜的投食方式是将植物插入盛水的瓶内；幼虫喜食东亚飞蝗卵块，尤其是顶端微露于土表的卵块最易被中华豆芫菁1龄幼虫找到并取食。

The research of antifeedant toxicity of bitter almond oil against 3th instar larve of Mythimna separata Walke showed that under the higher concentration, the antifeedant rates are above 95.78% at the test time, but under the lower concentration, the antifeedant rates are decreased with prolonging the treatment time.

苦杏仁精油对粘虫的拒食活性结果表明在高浓度下，精油对粘虫的拒食率达95.78%以上，而低浓度精油随着处理时间的延长，对粘虫的拒食活性逐渐降低。

Methods iv instar larve of cx.pipiens pallenswere treated with propoxur at the dose of lc 50 in each generation and remaining survival larrae were fed under laboratory conditions.who bioassay was employed for detection of resistance of mosquitoes.

在实验室条件下，用残杀威以lc 50 的剂量处理iv龄幼虫，选育残杀威抗性品系。按照who生物测定法，测定抗残杀威品系对多种杀虫剂的敏感性。

Temperature also affected, to some extent, the trend of the abundance of mycetocytes following the development of aphids. The abundance of mycetocytes increased with the development from nymph to adult before larviposition in the aphid at 15℃, 20℃ and 25℃, but culminated at the 3rd instar and thereafter declined at higher temperatures (30℃ and 35℃).
