摘要
[目的]明确暗黑鳃金龟成虫产卵量的影响因素,为人工饲养暗黑鳃金龟提供参考.[方法]采用不同食物、不同性比、不同饲养密度、不同土壤类型以及不同根际土等条件处理暗黑鳃金龟成虫,研究其对暗黑鳃金龟成虫产卵量的影响.[结果]喂食榆树叶成虫的产卵量最高,喂食槐树叶成虫的产卵量最低;不同性比条件下,雌虫的比例大产卵量高,雌雄比例为3∶1时产卵量最高,雌雄比例为1∶1时最早达到产卵高峰期;不同密度下,暗黑鳃金龟成虫单位面积产卵量随成虫数量增加而增大,但单雌产卵量随密度增大而降低;单箱饲养密度在200头左右最佳;黏土为最适宜成虫产卵的土壤环境;成虫在种植小麦的根际土中的产卵量最高.[结论]在暗黑鳃金龟的室内人工饲养中,暗黑鳃金龟成虫的产卵量受食物、性比、饲养密度、土壤等多种因素的影响.
Abstract
[Objective] Influencing factors on fecundity of Holotrichia parallcla Motschulsky were cleared to provide reference for artificial feeding of Holotrichia parallcla Motschulsky.[Method] We treated Holotrichia parallcla by different conditions of food, sex ratio, stocking density and soil, and studied the effect on fecundity of Holotrichia parallcla Motschulsky.[Result] The number of the adult eggs was highest by feeding elm leaves and lowest by feeding Ash leaves;Under the condition of different sex ratio, a larger proportion of female was useful to female lay eggs, the highest fecundity by the proportion of male and female 1∶3, the first to reach spawning peak ratio was 1∶1;the fecundity per unit area of Holotrichia parallcla was increased with the number of adults, but egg number per female was decrease with density increases;the best stocking density was about 200;clay soil was the most suitable environment for laying eggs;adult fecundity was highest in the wheat plant soil.[Conclusion] In artificial rearing of Holotrichia parallcla, the fecundity of adult was influenced by factors, such as food, sex ratio, stocking density, soil and so on.
