摘要
斑翅果蝇(SWD)、铃木果蝇(Matsumura,1931 年)(双翅目:果蝇科)会给外果皮薄的水果造成产量损失和重要的经济影响。在本研究中,分析了硫磺粉与天敌/寄生虫结合防治 SWD 的效果。首先,评估了动力硫磺与受侵染草莓果实上的 Anthocoris nemoralis(半翅目:Anthocoridae)和 SWD 蛹上的 Trichropia drosophilae(膜翅目:Diapriidae)之间的相互作用。其次,还评估了捕食者/寄生虫接触草莓叶片与硫磺粉的情况。此外,还研究了硫磺粉对嗜水蝇寄生的亚致死效应。结果表明,硫磺粉不会干扰蚜蝇的活动,并能显著减少果实虫害。与此相反,硫磺影响了 T. drosophilae 的活性,当两种药剂结合使用时,寄生率降低。直接接触硫磺粉不会导致花叶蓟马和嗜果蝇大量死亡。最后,在寄生率和性别比例方面,之前接触过硫磺对 T. drosophilae 没有影响。根据本文得出的结果,硫磺和嗜酸芋螺(T. drosophilae)分别施用时会对不同阶段的 SWD 产生影响。不过,在对 SWD 采取综合防治策略时,应考虑到硫磺对 T. drosophilae 的影响。
Compatibility of powdered sulphur and natural enemies for the control of Drosophila suzukii (Diptera: Drosophilidae): Effects on Anthocoris nemoralis (Hemiptera: Anthocoridae) and Trichopria drosophilae (Hymenoptera: Diapriidae) activity
Spotted-wing drosophila (SWD), Drosophila suzukii (Matsumura, 1931) (Diptera: Drosophilidae) cause yield losses and important economic impacts in fruits with thin epicarp. In the present study, the combination of powdered sulphur and predators/parasitoids for the control of SWD was analysed. First, the interaction of powered sulphur with Anthocoris nemoralis (Hemiptera: Anthocoridae) on infested strawberry fruits and Trichropia drosophilae (Hymenoptera: Diapriidae) on SWD pupae was evaluated. Second, exposure of predators/parasitoids to strawberry leaves with powdered sulphur was also assessed. Additionally, sublethal effects of powdered sulphur on T. drosophilae parasitism were examined. The results show powdered sulphur did not interfere with the activity of A. nemoralis and caused a significant reduction in fruit infestation. In contrast, sulphur affected the activity of T. drosophilae, reducing parasitism when the two agents were combined. Direct exposure to powdered sulphur did not cause significant mortality of A. nemoralis and T. drosophilae. Finally, previous exposure to sulphur did not affect T. drosophilae in terms of parasitism rates and sex ratio. Based on the results obtained herein, sulphur and T. drosophilae impacts on different stages of SWD when they are applied separately. However, the effects of sulphur on T. drosophilae should be taken into account in combination control strategies of SWD.
