【摘要】 瞬时极端高温、一天内极端高温持续时间对美洲斑潜蝇各虫态死亡率及极端高温的持续天数对蛹存活和成虫寿命及产卵量影响的研究表明：卵、１龄、２龄、３龄幼虫、蛹及成虫的半数致死瞬时极端高温分别为：５１．４、５１．１、５２．２、５３．５、４１．１和４３．９°Ｃ；各虫态死亡率随极端高温持续时间的增长而提高，死亡率与极端高温及持续时间呈二次曲线关系； ４０°Ｃ下每天持续３ｈ高温，蛹死亡率、成虫寿命和产卵量与持续天数呈线性关系。更多还原

【Abstract】 Indoor experiments were conducted to test the influence of extreme high temperature (EHT) on the biology of Liriomyza sativae Blanchard. The LD50, of EHT on egg, first instar larva, second instar larva, third instar larva, pupa and adult were 51. 4, 51. l, 52. 2, 53. 5, 41. 1 and 43. 9°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. Under 40°Ｃ and a duration of 3 h, there were linear relations between the duration (in days) of EHTs and the pupal mortality, as well as the adult longevity and fecundity.更多还原
