    Effects of temperature on the growth and development in Aiolocaria hexaspilota (Coleoptera: Coccinellinae)

    • 摘要: 为探讨温度对六斑异瓢虫生长发育的影响,分别在15、20、25和28 ℃条件下,对六斑异瓢虫各发育阶段的发育历期、发育速率、发育起点温度、有效积温、存活率及幼虫体长进行了研究。结果表明:六斑异瓢虫在15~28 ℃的温度范围内,发育历期均随温度的升高显著缩短,发育速率随温度的升高而加快,采用线性回归模型对六斑异瓢虫各发育阶段的发育速率进行模拟分析,模型拟合度较高,P值均小于0.05,达到显著水平。温度对1~3龄幼虫体长无显著性差异;4龄时,15 ℃下的4龄幼虫体长只有11.48 mm,显著短于其他温度。温度对六斑异瓢虫存活有一定的影响,随着温度的升高,总存活率呈下降趋势,28 ℃时最低,只有54.53%。综合各指标,适宜六斑异瓢虫生长的环境温度为15~20 ℃,六斑异瓢虫卵、1龄、2龄、3龄、4龄、蛹和总历期的发育起点温度分别为9.84、10.42、11.67、10.21、9.91、10.51、10.37 ℃,有效积温分别为54.49、26.77、19.32、27.35、54.73、73.37、269.77 ℃·d。

       

      Abstract: In order to explore the effects of temperature on the growth and development of Aiolocaria hexaspilota, the development duration in each development stage, development rate, development threshold temperature, effective accumulative temperature, survival rate, and larva body length were studied under the temperature of 15, 20, 25 and 28 ℃. Results showed that: within the temperature range of 15-28 ℃, all development duration shortened significantly, while the development rate speeded up with the rise of temperature. Using linear regression model to simulate the growth rate of each development stage of A. hexaspilota, the fitness was high and all the P value was less than 0.05, reached significant level. There was no significant difference in body length among 1-3 instar larvae under different temperatures. Whereas for 4th instar larva, the larva body length at 15 ℃ was obviously shorter than other temperature, only 11.48 mm. The results also showed that the survival rate of A. hexaspilota was influenced by temperature. With the increase of temperature, total survival rate trended down. At 28 ℃, survival rate reached the lowest value, only 54.53 %. In conclusion, the optimum temperature for A. hexaspilota growing was 15-20 ℃. The development threshold temperatures of A. hexaspilota from egg, 1-4 instar larvae to adults, and total duration were 9.84, 10.42, 11.67, 10.21, 9.91, 10.51 and 10.37 ℃, respectively. And the effective accumulated temperatures of above stages were 54.49, 26.77, 19.32, 27.35, 54.73, 73.37 and 269.77 ℃·day, respectively.
