Resistance of adults in Leptocybe invasa Fisher & La Salle to extreme temperatures

In order to understand the resistance of adults in Leptocybe invasa to extreme temperatures, exposure experiment and cold acclimation experiment were used to test the resistance ability of adults from different seasons to extreme temperatures. The results showed that, L. invasa adults had both certain basal tolerance and induced tolerance to extreme temperatures, and compared with autumn, summer bodies had higher heat resistance but lower cold resistance, autumn bodies were contrary. Besides, cold acclimation experiment proved that long-term exposure under non-lethal low temperature may cause chilling injure to insects.
