Wheat fertilization affects oviposition preference of wheat midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae)

Pest Management Science, EarlyView.
Wheat fertilization increased plant growth, nitrogen and protein levels, influencing the wheat volatile profile and affecting female wheat midge choice to lay eggs. This could partly result from the observed changes in the VOC profile. Abstract BACKGROUND In Canada, the orange wheat blossom midge (hereafter called wheat midge), Sitodiplosis mosellana ...

Host phenology‐driven infestation patterns of the carob moth (Ectomyelois ceratoniae) in Mediterranean walnut orchards: insights from comparison with codling moth (Cydia pomonella)

Pest Management Science, EarlyView.
In Mediterranean walnut orchards, Ectomyelois ceratoniae replaces Cydia pomonella as the primary pest. Capture peaks between packing tissue brown (PTB) stage and husk dehiscence define a critical window for monitoring and early harvest to prevent kernel infestation.

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

Pest 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 [

Leaf penetration by endophytic Metarhizium brunneum enables infection of Phthorimaea absoluta in tomato mines while inducing the crop defense system

Pest Management Science, EarlyView.
Spraying Metarhizium brunneum on tomato plants controls heterogeneous and upcoming Phthorimaea absoluta populations by infecting larvae within mines and priming plant induced systemic defences. Abstract BACKGROUND The endophytic entomopathogenic fungus Metarhizium brunneum Petch EAMa 01/58‐Su shows strong potential for managing Phthorimaea absoluta, a ...
