| 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。

| Abstract: | 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. |
