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.

枣核甲虫 Coccotrypes dactyliperda（鞘翅目：Curculionidae：Scolytinae）会侵扰杏仁（Prunus dulcis）作物吗？

摘要

19 世纪和 20 世纪初的独立观察发现，枣核甲虫Coccotrypes dactyliperda Fabricius 会以杏仁为食并在其中繁殖。由于食精虫 C. dactyliperda可能对杏仁产业构成威胁，因此在受控喂养实验中向甲虫提供了四种不同的杏仁品种。杏仁被普遍拒绝，似乎与之前的观察相矛盾。建议进一步研究的方向，检查基于谱系的味觉偏好，以及包装供人类食用的杏仁是否易受伤害，而天然和新鲜去壳的杏仁则不然。
