摘要/Abstract

摘要： 采用热敏电阻法对瓜实蝇1日龄幼虫、5日龄幼虫、1日龄蛹、3日龄蛹、5日龄蛹、1日龄雌成虫、1日龄雄成虫、5日龄雌成虫、5日龄雄成虫进行过冷却点和结冰点的测定。结果表明：各虫态以5日龄蛹的过冷却点和3日龄蛹的结冰点最低，分别为（-16.72±0.23）℃和（-13.14±0.55）℃；以5日龄幼虫的过冷却点和结冰点最高，分别为（-14.32±0.45）℃和（-5.52±0.47）℃；各虫态的过冷却点由低到高的顺序为：5日龄蛹＜3日龄蛹＜5日龄雄成虫＜1日龄雄成虫＜1日龄蛹＜5日龄雌成虫＜1日龄幼虫＜1日龄雌成虫＜5日龄幼虫。

Abstract: Thermistor method were conducted to examine the super-cooling point and freezing point for adult, larva and pupa of Bactrocera（Zeugodacus）cucurbitae（Coquillett）. Results showed that the super-cooling point of 5 day-old pupa and freezing point of 3 day-old pupa were the lowest, which was（-16.72±0.23）℃ and（-13.14±0.55）℃, respectively. The super-cooling point and freezing point of the 5th instar larvae were the highest, which was（-14.32±0.45）℃ and（-5.52±0.47）℃, respectively. The sequence of super-cooling point from low to high is 5 day-old pupa＜3 day-old pupa＜5 day-old male adult＜1 day-old male adult＜1 day-old pupa＜5 day-old female adult＜the 1st instar larvae＜1 day-old female adult＜the 5th instar larvae.

Key words: Bactrocera（Zeugodacus）cucurbitae（Coquillett）, Super-cooling point, Freezing point
