Examines how cotton reproductive structures affect boll weevil development, reproduction, and survival, suggesting improved pest management strategies.

Key Points

The study aims to understand how cotton reproductive structures impact boll weevil survival and reproduction through nutritional pathways.
Examined host usage and physiological pathways in boll weevils
Compared effects of different food sources on larval and adult development, survival, and reproduction
Analyzed vitellogenin expression in relation to diet
Larvae fed on bolls had longer developmental times and larger body sizes
Adult boll weevils accumulated more lipid reserves but experienced reduced fecundity
Flower bud-fed females showed higher protein content and increased egg production
Vitellogenin expression was 2.5-fold higher in bud-fed compared to boll-fed females
