Abstract
Walnut husk fly (WHF), Rhagoletis complete Cresson, is a serious insect pest of walnuts in California.
Control of WHF relies on repeated applications of broad-spectrum insecticides combined with a feeding stimulant to suppress adult flies before oviposition.
Initiation of control measures relies on monitoring emergence of adult flies with yellow sticky traps with ammonium carbonate lures.
Research reported here shows that there was a significant difference among commercially available traps and lures in WHF captures.
The difference appears to be the result of ammonia release rate among commercial lures and not the trap design or sticky surface.
