摘要未成熟的昆虫在植物结构中发育完全取决于它们的父母选择合适的寄主。在果树果实中生长的象鼻虫就是这种情况的一个明显例子。我们研究了产卵选择的黑核桃象鼻虫，Conotrachelus retentus（说），在核桃种植园设置10年，专注于集群大小对产卵的影响。坚果集群与curculio产卵的百分比没有显着差异集群大小之间，虽然个别坚果被破坏的百分比显着低于单坚果相比，两个坚果集群。我们的数据支持的假设，curculio的行为，好像坚果集群是产卵的生态单位，其他象鼻虫，如山核桃象鼻虫。
Abstract Immature insects that develop within plant structures entirely of their parent’s choosing are dependent on those parents to select suitable hosts. Weevils that develop within tree fruits are an obvious example of this situation. We examined oviposition choice by the black walnut curculio, Conotrachelus retentus (Say), in a walnut plantation setting for 10 yr, focusing on the effects of cluster size on oviposition. The percentage of nut clusters with curculio oviposition did not differ significantly among cluster sizes, although the percentage of individual nuts destroyed was significantly lower in single nuts compared with two-nut clusters. Our data support the hypothesis that the curculio behaves as though the nut cluster was the ecological unit for oviposition, as do other weevils such as the pecan weevil.
