在恒温条件下,观察了21～33℃范围内甘蔗红尾白螟蛹的发育历期,并测定了其发育起点温度和有效积温。结果表明,红尾白螟蛹发育历期与温度呈负相关,蛹的发育起点温度为(14.129±0.529)℃,有效积温为(191.003±7.461)℃,发育历期预测式为N=(191.003±7.461)/T-(14.129±0.529),可用于成虫发生期和防治适期的预测。
Under the condition of constant temperature, the developmental duration of pupal pupae was examined in the range of 21 ~ 33 ℃, and the developmental starting temperature and effective accumulated temperature were measured. The results showed that the developmental duration of pupal pupae was negatively correlated with temperature. The onset temperature of pupae was (14.129 ± 0.529) ℃, the effective accumulated temperature was (191.003 ± 7.461) ℃, the predictive value of developmental duration was N = (191.003 ± 7.461) / T- (14.129 ± 0.529), which can be used to predict the occurrence and control of adult worms.
