温度对花翅摇蚊实验种群的影响
Effect of temperature on laboratory population of Chironomus kiiensis
摘要
Abstract
Development,growth and reproduction of the Chironomus kiiensis experimental populations were observed under different temperature.It was found that under 18 ～ 34 ℃ the developmental duration decreased while the developmental rate increased linearly with temperature.The relationship between the developmental rate and temperature were further described with five regression equations,which could be applied to predict occurrence period and effective accumulative temperature.The development threshold temperature and effective accumulative temperature for whole generation were 6.68 ℃ and 742.97 day-degrees,respectively.In the tested temperature range,both intrinsic rate of increase (rm) and finite rate of increase (λ) increased with temperature until a maximum of 0.175 and 1.191 at 34℃,respectively.Net reproduction rate (R0) reached its highest value at 26 ℃.The shortest mean generation time (T) and double population time (t) were obtained at 34 ℃,with values of 24.53 d and 3.96 d,respectively.It could be concluded that Chironomus kiiensis was sensitive to temperature and 30 ～34 ℃.关键词
