The codling moth Cydia pomonella (L.) is a worldwide pest of pome fruit. A better understanding of oviposition site selection by this insect would help management of this pest in orchards. Oviposition site selection of codling moth was assessed by manipulative experiments and field survey. In addition, the temperatures of different sites were recorded. Neonate infestation and egg hatching were tested to evaluate the consequences of oviposition site selection. The percentage of eggs laid on the shady side of apple clusters was significantly higher than on the sunny side. How.ever, this was not influenced by leaf surface turning. Percentage of eggs on upper and lower leaf surfaces was significantly influenced by leaf surface turning. Percentage of eggs on the lower leaf surface was significantly higher than turned lower leaf surface (∼41.1% higher) and significantly higher (∼35.5%) on the turned upper leaf surface on than upper leaf surfaces. There was no significant difference in neonate infestation between leaves and fruit, as well as between the upper and lower leaf surfaces. Number of eggs hatching on the shady side of clusters was significantly higher than on the sunny side (56.3% higher). In both the manipulative experiment and field survey, codling moths did not choose the sites with the highest mean temperature, but chose sites suitable for egg development and hatching. This indicates that in the field codling moth, oviposition site selection is not strictly thermophilous, but they look for the lower leaf surface on the shady side, which benefits the offspring.
苹果蠹蛾Cydia pomonella (L.)是一种危害全球梨果类水果的害虫。更好地了解这种昆虫的产卵位点选择有助于果园中该害虫的防治。通过操纵实验和田间调查评估了苹果蠹蛾的产卵位点选择。此外，记录了不同位点的温度。通过测试初孵幼虫侵染情况和卵孵化情况来评估产卵位点选择的后果。产在苹果果簇阴面的卵的百分比显著高于阳面。然而，这不受叶片表面翻转的影响。叶片上下表面的卵的百分比受叶片表面翻转的显著影响。下叶表面的卵的百分比显著高于翻转后的下叶表面（约高41.1%），且在翻转后的上叶表面显著高于上叶表面（约高35.5%）。叶片和果实之间以及叶片上下表面之间的初孵幼虫侵染情况没有显著差异。果簇阴面孵化出的卵的数量显著高于阳面（高56.3%）。在操纵实验和田间调查中，苹果蠹蛾都没有选择平均温度最高的位点，而是选择了适合卵发育和孵化的位点。这表明在田间苹果蠹蛾中，产卵位点选择并非严格嗜热，而是会寻找阴面的下叶表面，这对后代有益。
