Mutualism between insects and symbiotic bacteria drives insect evolution, insecticide resistance is affected by bacteria, increasing the complexity of pest resistance. This study evaluated sublethal transgenerational effects neonicotinoid nitenpyram on population dynamics Acyrthosiphon gossypii measured its impact bacterial community. The results showed that LC20 (2.49 mg·L−1) significantly reduced fecundity lifespan parent G0 generation A. gossypii, had similar inhibitory G1 G2 generations. Compared with those control group, parameters λ (finite rate increase), R0 (net reproductive rate), r (intrinsic increase rate) were reduced, but mean time (T) was increased. Nitenpyram treatment biological traits also changed relative abundance Buchnera Sphingomonas in three consecutive generations G0-G2. Under treatment, decreased G0, while increased G2, decreased. Our findings may provide a new perspective for evaluating potential pesticides aphids.
