环xaprid是一种新型顺式新烟碱类杀虫剂，对多种害虫有效，包括对传统新烟碱类具有抗性的害虫。本研究采用生命表参数评价环xaprid对棉蚜的亚致死效应。结果表明，环xaprid LC20 （0.81 mg a.i. L−1）可显著缩短首代成虫的产卵前期。此外，F1代成年人的预期寿命缩短。然而，在F1个体的内在增长率（ri）、有限增长率（λ）、净繁殖率（R0）和平均世代时间(T)方面没有观察到显著差异。因此，低浓度环磷酰胺可能不会引起棉蚜种群的死灰复燃。此外，解毒酶的反应表明，环xaprid在LC20处抑制细胞色素P450单加氧酶（P450）和谷胱甘肽s -转移酶（GST）活性，暴露后6 h。这种抑制P450和GST活性的作用可导致环xaprid代谢降低，从而提高环xaprid的疗效。因此，我们的研究结果有助于评估环xaprid对棉蚜的整体效果。
Cycloxaprid is a novel cis-configuration neonicotinoid insecticide that is effective against a wide range of insect pests, including those that are resistant to conventional neonicotinoids. In this study, life table parameters were applied to estimate the cycloxaprid-induced sublethal effects on Aphis gossypii. The results indicated that the LC20 (0.81 mg a.i. L−1) of cycloxaprid significantly decreased the pre-oviposition period in first-progeny adults. Additionally, the life expectancy of F1 generation adults was reduced. However, no significant differences were observed for the intrinsic rate of increase (ri), finite rate of increase (λ), net reproductive rate (R0), or mean generation time (T) of F1 individuals. Therefore, resurgence in the A. gossypii population induced by a low concentration of cycloxaprid might not occur. Additionally, the response of the detoxification enzymes showed that cycloxaprid at the LC20 inhibited cytochrome P450 monooxygenase (P450) and glutathione S-transferase (GST) activities at 6 h after exposure. Such inhibition of P450 and GST activities could lead to a decrease in the metabolism of cycloxaprid, which would increase the efficacy of cycloxaprid. Therefore, our results contribute to the assessment of the overall effects of cycloxaprid on A. gossypii.
