植物化感物质是植物产生的一组次生代谢产物，用于防御植食性天敌。采用取食法研究了单宁酸和棉酚两种植物化感物质对棉蚜（Aphis gossypii格洛弗）的死亡率，并采用年龄阶段两性生命表法研究了其亚致死效应。单宁酸和棉酚对A.随着浓度的增加，棉蚜的死亡率增加。生活史特征分析表明，A.亚致死浓度单宁酸（20 mg/L）和棉酚（50 mg/L）对棉蚜各若虫期发育历期、寿命、产卵天数、成虫前期存活率和成虫前期产卵期无显著影响，但对种群参数（r、λ和R 0）有显著影响。鞣酸能延长成虫前期历期和TPOP，但降低了成虫的繁殖力。与对照组和棉酚处理组相比，这些结果有助于全面认识植物化感物质对拟南芥的影响。棉。
Plant allelochemicals are a group of secondary metabolites produced by plants to defend against herbivore. The mortality of two plant allelochemicals (tannic acid and gossypol) on the cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), were investigated using feeding assays and the sublethal effects were evaluated using the age-stage, two-sex life table approach. Tannic acid and gossypol have deleterious effects on A. gossypii, and as the concentrations increased, the mortality of cotton aphid increased. The life history traits of A. gossypii including the developmental duration of each nymph stage, the longevity, oviposition days, total preadult survival rate and adult pre-oviposition period were not significantly affected by sublethal concentration of tannic acid (20 mg/L) and gossypol (50 mg/L), while the population parameters (r, λ and R0) were significantly affected by these two plant allelochemicals. Furthermore, tannic acid can increase the pre-adult duration time and TPOP but reduce the fecundity of A. gossypii significantly compared to the control and gossypol treatment groups. These results are helpful for comprehensively understanding the effects of plant allelochemicals on A. gossypii.
