The hormetic effect may cause disease control measures to fail due to inadequate treatment of human disease vectors such as houseflies. Age-stage, two-sex life table is used for accurate estimation of the hermetic impacts on insects as it allows to study sub-lethal or transgenerational effects. Pyrethroids insecticides are primarily used for the management of houseflies. This study used lambda-cyhalothrin (a pyrethroid insecticide) to quantify its transgenerational impacts on houseflies. Life table parameters of a progeny of adult houseflies exposed to LC, LC and LC of lambda-cyhalothrin were computed. Statistically higher fecundity (71.31 per female) was observed in control treatment, while it was the adults exposed to LC recorded the lowest progeny. Significantly higher values for intrinsic rate of growth (r), limiting rate of growth (λ), and net reproductive rate (R) (0.16, 1.16, and 31.38 per day, respectively) were recorded for the control treatment of the study. Contrarily, lower values for λ, R and r were (0.10, 1.10, and 9.24 per day, respectively) were noted in the LC treatment. Decreased population parameters suggest that lambda-cyhalothrin can be successfully used in indoor environments to control houseflies.
由于未能充分处理家蝇等人类疾病媒介，激效作用可能导致疾病控制措施失败。年龄-阶段-两性生命表可用于准确估计对昆虫的激效影响，因为它可以研究亚致死或跨代效应。拟除虫菊酯类杀虫剂主要用于防治家蝇。本研究使用氯氟氰菊酯（一种拟除虫菊酯类杀虫剂）来量化其对家蝇的跨代影响。计算了接触 LC、LC 和 LC 氯氟氰菊酯的成年家蝇后代的生命表参数。在对照处理中观察到的雌蝇生育力（71.31 只）明显较高，而接触 LC 的成虫则记录到的后代最少。对照处理的内禀增长率（r）、限制增长率（λ）和净生殖率（R）（分别为 0.16、1.16 和 31.38 天）的记录值显著更高。相反，LC 处理的 λ、R 和 r 的值较低（分别为 0.10、1.10 和 9.24 天）。种群参数的降低表明氯氟氰菊酯可以成功地在室内环境中用于控制家蝇。
