A spider mite control method using night-time ultraviolet (UV)-B irradiation was recently developed for strawberry greenhouses (UV method). The control effect of this UV method is negatively affected by increasing temperature. Tetranychus urticae eggs are more resistant to a single dose of UV-B irradiation than Neoseiulus californicus eggs. By contrast, N. californicus can better survive nightly UV-B irradiation with the UV method compared with T. urticae. To elucidate the mechanism underlying these phenomena, we explored the hypotheses that higher temperature promotes photoenzymatic repair (PER) and that mortality is determined by UV-B susceptibility in the embryonic stage exposed to UV-B.

温度和 UV-B 对红蜘蛛和植绥螨卵孵化的影响和相互作用的机制

最近为草莓温室开发了一种使用夜间紫外线 (UV)-B 照射的红蜘蛛防治方法（紫外线方法）。这种UV方法的控制效果受到温度升高的负面影响。Tetranychus urticae卵比Neoseiulus californicus卵更能抵抗单剂量的 UV-B 辐射。相比之下，与T. urticae相比，使用 UV 方法的N. californicus可以更好地在夜间 UV-B 照射下存活。为了阐明这些现象背后的机制，我们探索了更高温度促进光酶修复 (PER) 的假设，并且死亡率由暴露于 UV-B 的胚胎阶段的 UV-B 易感性决定。
