试验结果表明:利氏才女虫幼虫对盐度的适应能力与原栖所的盐度有关,来源于较高盐度的利氏才女虫对高盐度的适应能力较强,来源于较低盐度的对低盐度适应能力较强,盐度驯化能增强利氏才女虫幼虫对盐度的适应。在试验温度17℃、盐度19.5的条件下,茶籽饼对利氏才女虫幼虫的存活有显著的影响,茶籽饼对利氏才女虫幼虫的24 hLC50和48 hLC50值及其95%置信区间分别是:4.81(4.10~5.64)mg/L、3.85(3.42~4.34)mg/L。
The results showed that the adaptability of the larvae of Litter to the salinity was related to the salinity of the habitat. The larvae with higher salinity had stronger ability to adapt to high salinity, which was derived from lower salt The degree of adaptability to low salinity is strong, salinity acclimation can enhance the female Riceni larvae to adapt to the salinity. At the test temperature of 17 ℃ and the salinity of 19.5, the tea seed cake had a significant effect on the survival of larvae of the female. The 24 hLC50 and 48 hLC50 value of the tea seed cake and its 95% confidence level The intervals were: 4.81 (4.10 ~ 5.64) mg / L and 3.85 (3.42 ~ 4.34) mg / L, respectively.
