Identification of Volatile Compounds Involved in Host Location by Anthonomus grandis (Coleoptera: Curculionidae)

Frontiers in Ecology and Evolution, 2018
Phytophagous insects rely on plant volatiles to locate suitable hosts upon which to feed or oviposit. The boll weevil, Anthonomus grandis, is the main pest on cotton crops in the Neotropical region and is attracted to host plant volatiles, especially ...

From flower buds to bolls: how cotton reproductive structures shape boll weevil development, reproduction and survival

Pest Management Science, EarlyView.
Female boll weevils feeding on flower buds promote reproduction regardless of their immature diet, whereas boll feeding increases lipid reserves and lifespan, revealing a nutrition‐driven trade‐off that sustains survival and reproduction in tropical boll weevil populations.
