两种温度下异长足漠甲(鞘翅目：长足漠甲族)幼期生长发育比较

Growth and development of immature Adesima anomala dejeani Gebl( Tenebrionidae: Adesmini) under two temperatures

本研究首次报道温度对异长足漠甲Adesima anomala dejeani Gebl生长发育的影响。异长足漠甲的整个变态过程饲养使用矿泉水瓶法,并优化了此方法,避免过度失水,进行加水并同时观察。随着温度的升高,发育历期缩短,30℃饲养条件下异长足漠甲的总发育历期为117.4 d,33℃的总发育历期为90.99 d;2龄期、5龄期幼虫的头壳长和宽,前胸长和宽,体长,在33℃饲养条件下显著高于30℃;7龄期幼虫的头壳长和宽,前胸宽,体长,在33℃饲养条件下显著高于30℃;5龄期幼虫,温度30℃时的体重为(0.0634±0.021)g,33℃时的体重为(0.0906±0.0313)g,差异显著;6龄期幼虫,蛹期、孵化成虫在温度30℃时存活率高于33℃。

The effects of two different temperatures on the growth and development of Adesima anomala dejeani Gebl was investigated under laboratory conditions. The method of using a mineral water bottle for feeding throughout metamorphosis was optimized. At 30℃ , the larvae period was 117.4 days compared to 90.99 days at 33℃. The cephalic capsule length and width, elytra length and width of the second and fifth instars were significantly greater at 33 ℃ than at 30℃. There was a significant difference in body weight of the fifth instar at 30℃ （0. 0634±0. 021 ） g and 33℃ （0. 0906±0. 0313） g. Survival rates of the sixth instar, prepupa and teneral adults were higher at 30℃ than at 33℃.
