| description | <i>Aphis gossypii</i> Glover, a widespread insect, presents a substantial danger to global agriculture. Lambda-cyhalothrin is a pyrethroid insecticide that has been widely studied for its effects on arthropods. Studies have reported that sublethal doses of insecticides can produce various consequences on arthropod reproduction. Hence, the objective of this research was to examine the potential effects of a sublethal dose of lambda-cyhalothrin (LC<sub>30</sub>, 1.15 mg/L) on <i>A. gossypii</i>, for which we created life tables and conducted qPCR analysis. Adult longevity, fecundity, net reproductive rate (<i>R</i><sub>0</sub>), body length, width, weight, and the expression of vitellogenin (<i>Vg</i>) and vitellogenin receptor (<i>VgR</i>) genes were not significantly altered by lambda-cyhalothrin treatment at LC<sub>30</sub> concentration in the F<sub>0</sub> generation of <i>A. gossypii</i> adults. The intrinsic rate of increase (<i>r</i>) and finite rates of increase (<i>λ</i>) decreased significantly, while the mean generation time (<i>T</i>) increased. In addition, <i>Vg</i> and <i>VgR</i> gene expression levels were significantly higher in the F<sub>1</sub> and F<sub>2</sub> generations, whereas body length, width, and weight were notably reduced. The developmental duration, longevity, <i>r,</i> and <i>λ</i> did not differ significantly from those of the control group. Thus, the sublethal and intergenerational stimulatory effects of lambda-cyhalothrin were observed in <i>A. gossypii</i>, and the alterations in <i>Vg</i> and <i>VgR</i> in <i>A. gossypii</i> were strongly associated with sublethal effects. The results of this research offer valuable knowledge regarding the indirect impacts of lambda-cyhalothrin on <i>A. gossypii</i>, which can be utilized as a theoretical foundation for the prudent utilization of insecticides to combat this pest and devise strategies for managing resistance. |
