中文摘要:
【目的】 棉露尾甲Haptoncus luteolus Erichson是棉花和番荔枝科等植物上重要的传粉昆虫,研究其室内人工饲养技术对于开发其传粉价值和以其为对象进行转基因棉花安全性评价等方面具有重要意义。【方法】 利用筛选的人工饲料和油菜花粉2种潜在的人工饲料,同时以天然饲料丝瓜花为对照,观察比较棉露尾甲初孵幼虫在3种饲料上的生长发育及羽化为成虫后的繁殖力差异。【结果】 棉露尾甲初孵幼虫在3种饲料上发育至成虫的生存曲线无显著差异;与丝瓜花和油菜花粉相比,人工饲料饲养棉露尾甲的幼虫期缩短,蛹期延长;人工饲料饲养的雌成虫羽化后20 d内累计产卵量显著高于丝瓜花和油菜花粉处理,且可以维持较长时间的单日高产卵量,从而显著提高繁殖力。【结论】 人工饲料饲养的棉露尾甲生物学特征与丝瓜花饲养的相似,但繁殖力显著提高,可以利用人工饲料结合配套的饲养技术进行棉露尾甲的室内长期大量饲养。
英文摘要:
[Objectives] To develop an artificial
feeding technology for Haptoncus luteolus,
an important pollinator of cotton and annonaceous crops, in order will
facilitate exploiting the pollination services of this species and assess its
vulnerability to transgenic Bt cotton. [Methods] The growth,
development of newly hatched larvae and adult fecundity of H. luteolus reared on artificial feed, rape pollen or luffa flower
were measured and compared. [Results] Survival curves of H. luteolus on these three diets were essentially the same.
Compared to those fed on rape pollen and luffa flower, H. luteolus reared on artificial feed had a shorter larval period
and longer pupal period. The cumulative number of eggs laid over 20 days by
females reared on the artificial feed was higher than that of females reared on
the other two diets. Females reared on artificial feed also maintained higher
fecundity for longer than those reared on the other foods. [Conclusion] With the
exception of higher fecundity, the biological
characteristics of H. luteolus reared
on artificial feed are essentially the same as when these insects are reared on
luffa flower. Using this artificial feed and related artificial breeding
technology could allow the long-term and large-scale feeding H. luteolus under laboratory conditions.
