摘　　要：In this study, Liriomyza sativaes was raised on Florist cinerarias in greenhouse with different temperatures at 15, 20, 25, 30 and 35 ℃, and their corresponding development duration of entire generation were 47.0, 25.0, 15.5, 12.5 and 12.0 d. The beginning growth temperatures of egg, larva, pupa and entire generation of Liriomyza sativae were 8.5, 9.8, 10.2 and 10.4 ℃, and their effective accumulated temperatures were 52.7, 75.8, 158.5 and 262.2 d ·℃, respectively. Liriomyza sativae had 7 generations on Florist cinerarias in Ningxia each year. However, it occurred in the whole year in greenhouse. The length of its development duration in greenhouse decreased in order from cucumber, Callestephus chinensis, Florist cinerarias to pea, but the eclosion rate of its pupa was in the eentrary order. Under the temperature of 10, 0, - 15 and 20 ℃ ,the longer the storage of pupa was,the higher the mortality rate would be. Liriomyza sativae couldn＇t survive in the winter in Ningxia Province in the natural environment.In this study,Liriomyza sativaes was raised on Florist cinerarias in greenhouse with different temperatures at 15,20,25,30 and 35 ℃,and their corresponding development duration of entire generation were 47.0,25.0,15.5,12.5 and 12.0 d.The beginning growth temperatures of egg,larva,pupa and entire generation of Liriomyza sativae were 8.5,9.8,10.2 and 10.4 ℃,and their effective accumulated temperatures were 52.7,75.8,158.5 and 262.2 d·℃,respectively.Liriomyza sativae had 7 generations on Florist cinerarias in Ningxia each year.However,it occurred in the whole year in greenhouse.The length of its development duration in greenhouse decreased in order from cucumber,Callestephus chinensis,Florist cinerarias to pea,but the eclosion rate of its pupa was in the contrary order.Under the temperature of 10,0,-15 and 20 ℃,the longer the storage of pupa was,the higher the mortality rate would be.Liriomyza sativae couldn't survive in the winter in Ningxia Province in the natural environment.
