基徵草蛉幼蟲集體飼育技術改進

本文為大量繁殖基徵草蛉及其他具自殘習性捕食性天敵，所發展出集體飼育其幼蟲之方法，具有降低操做工時、簡化流程之優點。在1.1公升之飼育盒中接種50隻初孵化幼蟲之密度下，以瓦楞紙卷為隱避場所者可以增加28%之成蟲獲得率。提供保麗龍屑或衛生紙屑為背負物者可以增加14%成蟲率。食物均勻灑佈餵食者可以提高9%成蟲率。將隱避場所、背負物、給食均勻等三因子複合可以得到約90%之成蟲獲得率。進一步試驗得知，在相同飼育盒中飼養100隻幼蟲，同時加入0.4g外米綴蛾卵及2.5ml保麗龍屑；每三天餵食1.4g飼料卵一次，均勻灑佈之，共二次。平均可以得到80%之成蟲率。草蛉幼蟲集體飼育方法應可予以肯定。

An improved, simplified, and labour-saving technique for group-rearing larvae of green lacewing, Mallada basalis, was developed. Using corrugated strip paper rolls and scratched polystyrofoam powder as shelter and debris decreased the larval cannibalism and produced 28% and 14% more adults than control, respectively. An evenly distributed food supply increased the rate of adult emergence 9%. The method including all these factors increased by 90% in total the lacewing larvae as adults. In a plastic box of size 14x 11.2x 7 cm, three rolls of corrugated strip paper of width 1.5 cm and length 185 cm were piled in three layers, and scratched polystyrofoam powder 2.5 ml mixed with frozen-sterilized Corcyra cephalonica eggs 0.4g were evenly distributed in the box. Then, 100 neonates of green lacewing were inoculated. The container was covered with polyethylene fine wrap and placed in a growth chamber at temperature 28±0.5℃, humidity 75±5% and photoperiod 14L:10D. Additional Corcyra eggs 1.4g were supplied on days 4 and 7 after inoculation. An average rate 80% of adult harvest was obtained. This effective rearing technique was established successfully.
