摘要: 比较了朱砂叶螨Tetranychus cinnabarinus (Boiduval)敏感品系(S)、阿维菌素抗性品系(AR)和甲氰菊酯抗性品系(FR)在不同温度下的发育和繁殖情况,用王-兰-丁模型拟合了各品系发育速率与温度的关系。结果表明,在36℃下,S品系和FR品系卵均不能孵化,而AR品系却能完成世代发育。15℃下,AR和FR品系的世代历期分别比S品系延长8.0和6.2天,产卵前期均比S品系缩短约2.0天。在20~28℃下,S品系繁殖力大于抗性品系; 在34℃下, AR品系的产卵量显著大于S和FR品系。S、FR和AR品系发育临界高温分别为36.0℃、36.1℃和42.4℃。结果提示AR品系对高温的适应能力较S和FR品系明显增强。

Abstract: For understanding the changing of biological characteristics of Tetranychus cinnabarinus  (Boiduval) which had developed resistance to acaricides, the biological characteristics of the susceptible strain (S), the abamectin-resistant strain (AR) and the fenpropathrin-resistant strain (FR) at different temperatures were assayed and compared. The relationship between temperature and growth speed of the three strains was simulated using the Wang-Lan-Ding Models. The results showed the eggs of the S and FR strains did not hatch at the high temperature of 36℃ while that of the AR strain could complete generation development. Compared to the S strain, the AR and FR strains extended generation developmental time 7.98 and 6.15 days, respectively, and shortened the pre-oviposition duration about 2 days at  the low temperature of 15℃. The fecundity of the S strain was higher than that of the two resistant strains within the temperature range of 20℃-28℃ while lower than that of the AR strain at 34℃. The maximum boundary temperatures of S, FR and AR strains were 36.0℃, 36.1℃and 42.4℃, respectively. The results suggest that the AR strain has stronger tolerance  to high temperature than the other two strains.
