Influene of extreme high temperature on the biology of vegetable leafminer liri- omyza sativae (diptera: agromyzidae)

摘要

Indoor experiments were conducted to test the influence of extreme high temperature (EHT) on the biology of Liriomyza sativae Blanchard. The LD_50 of EHT on egg, first instar larva, second instar larva, third instar larva, pupa and adult were 51.4, 51.1, 52.2, 53.5, 41.1 and 43.9 deg. C, respectively. The mortality of each stage increased with the prolongation of duration (in hours) of EHT. The quadratic Regression equations gave a good estimate of the mortality of the leafminer influenced by durations of EHTs.
