摘 要：
为探索乌蔹莓鹿蛾的人工饲养条件,就幼虫饲养密度(每瓶1头、3头、5头、7头、9头)和温度(25℃、28℃、31℃)对乌蔹莓鹿蛾的发育历期、存活率和取食等进行了研究。结果显示,与群体饲养相比,单头饲养的乌蔹莓鹿蛾幼虫的发育历期长,成活率低,取食量较大。在25～31℃的环境温度下,乌蔹莓鹿蛾幼虫的发育历期随温度升高而缩短,28～31℃较有利于幼虫生长发育,28℃的存活率最高(79.47%),31℃时幼虫取食量最大(2.45 g.头-1)。在人工饲养条件下,初龄幼虫以3～5头群体饲养为宜,3龄以后以单头饲养为宜,饲养温度以28～31℃为宜。

摘 要：
Artificial breeding conditions were used to investigate the effects of population density(1,3,5,7 and 9 heads in one culture bottle) and temperature(25 oC,28 oC,and 31 oC) on the development duration,survival percentage and feeding amount of Amata sp larvae.Compared with group breeding,single-head breeding prolonged the development time,lowered survival percentage and increased feeding amount.The development duration shortened with increased temperature at breeding temperature of 25～31 oC.A temperature range of 28～31 oC was beneficial to the growth and development of Amata sp.The highest survival percentage(79.47%) was obtained at a temperature of 28 oC,and the highest feeding amount per head(2.45 g) was obtained at 31 oC.The optimum artificial breeding conditions about population density were 3～5 heads per culture bottle at the first instar larval stage,and 1 head per culture bottle after the third larval instar stage.The breeding temperature range was 28～31 oC.
