本文研究了桃小食心虫的生物学和生态学特性。结果表明:桃小食心虫在四川西部1年发生1代;越冬幼虫出土数量与前旬降雨量呈正相关;幼虫出土至羽化的历期与温度呈负相关。并推导出了成虫初见日与5月份温雨系数的直线回归方程式。幻虫在果内的成活率随果实膨大而增加。幼虫危害苹果的空间分布型属典型的聚集分布。其聚集强度是:低密度,高聚集;高密度,低聚集。本文还研究了防治桃小食心虫的方法。
In this paper, the biological and ecological characteristics of peach moth were studied. The results showed that peach moth occurred in the first year in the west of Sichuan Province. The number of overwintering larvae was positively correlated with the rainfall in the first ten days of the year. The duration of emergence of the larvae to emergence was negatively correlated with the temperature. And deduced the linear regression equation between adult first sighting date and May rainy season coefficient. The survival rate of the phantom in the fruit increases with the fruit enlargement. The larvae endanger the spatial distribution of apple is a typical aggregation distribution. Its aggregation intensity is: low density, high concentration; high density, low aggregation. This article also studied the method of controlling peach moth.
