枣和酸枣桃蛀果蛾生物学特性异于苹果桃蛀果蛾。在适宜温湿度下,枣和酸枣桃蛀果蛾越冬幼虫出土始期和高峰期分别比苹果桃蛀果蛾晚8d和20多d,田间成虫发生期也晚约20d。恒温条件下,前两者的前蛹期+蛹期也均比后者短。桃蛀果蛾多产卵于枣果临近的叶背基部和酸枣梗洼处。幼虫在酸枣中需生活40～50d,一年发生1代。提出了桃蛀果蛾不同的“寄主生物型”概念。 Jujube and jujube peach moth biological characteristics different from apple peach fruit moths. Under appropriate temperature and humidity, jujube and jujube peach moth overwintering larvae were earlier and peaked 8 days and 20 days later than the apple peach moth, respectively, and adults in the field also occurred about 20 days later. Under the condition of constant temperature, the anterior pupal stage and pupal stage of the former two are also shorter than the latter. Peach moths lay eggs in the jujube fruit near the base of the leaves and jujube stems depression. Larvae need to live in jujube 40 ~ 50d, 1 generation a year. Proposed the peach moth different “host biological type” concept.
