摘要

Honeybees are essential global pollinators and key model organisms for studying insect social behavior. Genetic manipulation is crucial for understanding honeybee biology, but current methods rely on microinjecting early-stage embryos, which is technically challenging, inefficient, and often results in high embryo mortality. In this study, we identified AcQP, an ovary-targeting peptide from the Asian honeybee (Apis cerana), capable of delivering DNA specifically to ovarian cells and transmitting it to progeny via the laying queen. Notably, AcQP also targets the ovaries of Apis mellifera and other non-Apis species, including silkworms and mosquitoes. By integrating AcQP with the Gal4- upstream activation sequences system, we successfully introduced exogenous DNA into queen bee ovarian cells via abdominal spiracle injection. This study established an efficient ovary–targeted DNA delivery method, representing a significant advancement in honeybee genetic engineering.
