Would the date stone beetle Coccotrypes dactyliperda (Coleoptera Curculionidae: Scolytinae) infest almond (Prunus dulcis) crops?

Research output: Contribution to journalArticlepeer-review

Abstract

Isolated nineteenth and early twentieth century observations found that date stone beetles, Coccotrypes dactyliperda Fabricius would feed on and breed in almonds. As spermatophagus C. dactyliperda could pose a threat to the almond industry, beetles were offered four different almond varieties in a controlled feeding experiment. The almonds were universally rejected, seemingly contradicting previous observations. Directions for further research are suggested, examining lineage-based gustatory preferences and whether almonds packaged for human consumption are vulnerable while natural and freshly shelled almonds are not.
