Synergistic attraction: Development and field evaluation of a multicomponent lure for Zeugodacus cucurbitae based on host‐plant volatiles and gut bacterium‐derived volatiles

open access: yesPest Management Science, EarlyView.
The newly developed ternary blend was validated in field trials and proved highly effective in attracting both male and female Zeugodacus cucurbitae. Abstract BACKGROUND Zeugodacus cucurbitae is a global quarantine pest. Management of this pest relies heavily on chemical insecticides, which impose substantial environmental burdens. Male‐specific lures [
