摘要 本文明確了桃蛀螟的雌性生殖系统由1对卵巢、1对侧输卵管、1根中输卵管、1个交配囊和1个受精囊组成。依据雌性生殖系统发育的典型特征,即卵巢小管形态、卵粒的成熟度、脂肪体的多少及形态,将卵巢发育过程分为乳白透明期(Ⅰ级)、卵黄沉积期(Ⅱ级)、成熟待产期(Ⅲ级)、产卵盛期(Ⅳ级)及产卵末期(Ⅴ级)5个发育时期。在温度为20、25℃和30℃下,桃蛀螟初羽化成虫完成卵巢发育的全部过程(Ⅰ级~Ⅴ级)所需时间分别为11.43、938、8.62 d。经推算,桃蛀螟卵巢各级(Ⅰ级~Ⅴ级)的发育起点温度分别为22.88、21.1、16.55、18.44、1119℃,有效积温分别为0.37、4.45、23.22、35.10日·度和125.91 日·度。根据不同温度下卵巢发育的速度,建立了卵巢发育速率的预测模型,这为桃蛀螟的短期精准预报提供了科学依据。
