摘      要：Insect quantity is an important index for determining the degree of damage to *** brown planthopper(BPH),Nilaparvata lugens(Stal),is one of the most important rice pests in ***,we used two genotypes of BPH,a highfecundity genotype(HFG)and a low-fecundity genotype(LFG),to measure their ecological fitness and to explore possible causes for genotype differentiation by transcriptome *** results showed that there were significant differences in body weight,egg hatching rate and honeydew secretion between the HFG and LFG,particularly,the number of eggs laid per female was more *** analysis showed that a total of 1966 differentially expressed genes(DEGs)were mainly involved in energy metabolism,carbohydrate and lipid syn thesis,in sect horm one syn thesis and fecun dity-related ***,we found that the phosphorylation levels of AMPK,AKT and FoxO and the synthesis of ecdysone were different between the two genotypes of *** findings may partially explain the differenee in the ecological fitness between HFG and *** study is the first to compare the differences between two genotypes of BPH and to provide transcriptomic evidenee to further understand the fecundity of BPH.
