【Abstract】 The biological characteristics,developmental zero and effective temperature constant of Liriomyza sativae were studied The results showed that the developmental zero of egg,larva and pupa were (8 54±1 66)℃,(8 02±2 99)℃and (10 51±1 37)℃ The effective temperature constants of the egg, larva and pupa were (62 40±5 79),(72 21±11 89) and (141 20±14 11) day-degrees The developmental zero from egg to pupa was (9 78±1 05)℃ and the effective temperature constant was (270 74±19 77) day-degrees The emergence rates of adults under different temperature were also studied更多还原
