摘要
在室内利用不同颜色的饲养容器,对异色瓢虫Harmonia axyridis(Pallas)生长发育、体长体重变化及繁殖能力进行了比较研究。结果显示:不同环境颜色条件对异色瓢虫幼虫各龄历期均有显著影响;尽管蛹期受不同颜色影响显著,但其总胚后发育期在各处理间差异不显著。异色瓢虫1龄和2龄幼虫体长增量在不同颜色处理间无显著差异,但3龄幼虫在红色条件下体长增量显著小于其余各处理。不同环境颜色条件下异色瓢虫各虫期体重增量均有显著差异,而4龄幼虫体重增量在各处理中均显著大于其余各虫期,并占总胚后发育期体重增量的50%以上。异色瓢虫成虫的交配持续时间在各处理间无显著差异,但其产卵前期在黄色及绿色条件下显著小于其余各处理。其首堆产卵量在各处理间无显著差异,但在红色及自然光下的48h累计产卵量均显著小于其余处理。
In laboratory conditions, the effects of environment color on development, variation of body length and weight gain, and reproduction capability of Harmonia axyridis （Pallas） were investigated through rearing the beetle with differently colored containers. The results showed significant effects of different environment colors on the developmental duration of H. axyridis larvae in each instar. The total duration of postovarian development, however, was not significantly different among different color treatments although the effect of environment color on the pupal duration was significant. The different color treatments showed no significant effects on body length increase in 1st and 2nd instar, but the body length increase in 3rd instar in red color treatment was significantly less than in other color treatments. We also found significant effect of environment color on body weight gain. Especially, the weight gain in 4th instar was significantly greater than in other instars in each colored treatment and accounted for over 50 % weight gain in the duration of total postovarian development. Although the mating duration of H. axyridis was not significantly different among different color treatments, the pre-oviposition duration was significantly shorter in yellow and green treatments than in other treatments. In addition, the observation results of fecundity showed that the accumulated amount of eggs in 48 h was significantly less in red and natural light treatments than in other treatments.
