Interpretive Summary:

Technical Abstract: The Asian citrus psyllid, Diaphorina citri Kuwayama, is a vector of huanglongbing (citrus greening disease). We investigated heat tolerance of adults from a laboratory colony maintained at 28 degrees C by exposing them for various periods of time to temperatures ranging from 43 to 60 degrees C. When adult Asian Citrus Psyllid (ACP) were exposed to 43 degrees C, 99 percent died after an exposure period of 130 minutes (2.2 hours) and 100 percent died after an exposure period of 140 minutes (2.3 hours). No ACP died when exposed to 43 degrees C for 10 minutes. At 60 degrees C, 100 percent adult ACP were killed following an exposure period of six minutes. An average of 7.5 percent ACP was killed following 0.5 minutes (30 seconds) of exposure to this temperature. A model was generated for relating percentage mortality of psyllids exposed to different heat treatments.
