测定了烟蚜各虫态的发育起点温度(C)及有效积温(K),全代 C 为9.8℃,K 为98.9日度。不同测定者所得 C、K 值虽互有不同,用于推算虫态历期,结果相当一致。建立了温、湿度与各虫态存活率、雌虫产仔量的二次回归关系式,均在 F_(0.01)水平上显著;烟蚜各虫态的致死中温度(LT_(50))在高温端为29.16～32.43℃,在低温端则与虫体表是否沾水有关,无水时为-7.39～-9.12℃,有水时为-5.5～-6.21℃。烟蚜冬季低温死亡率与春季烟田迁入蚜量关系密切。温度显著影响有翅型比例,饲养温度17.9℃,有翅型占82.4%,饲养温度25℃,只占7.3%。
The developmental onset temperature (C) and effective accumulated temperature (K) of each myzoid were determined. The whole generation C was 9.8 ℃ and the K was 98.9 days. Although different C and K values obtained by different measurers are different from each other, they are used to calculate the worm state duration and the results are quite consistent. The regression equation of temperature and humidity, survival rate of each insect and litter size of females was established at the F_ (0.01) level. The lethal temperature (LT_ (50)) The high temperature end of 29.16 ~ 32.43 ℃, at the low end of the table and the parasites whether the water-related, anhydrous -7.39 ~ -9.12 ℃, with water -5.5 ~ -6.21 ℃. The mortality of cold aphid in winter was closely related to the amount of aphids moved into the tobacco field in spring. The temperature significantly affected the winged ratio, feeding temperature 17.9 ℃, winged 82.4%, feeding temperature 25 ℃, only 7.3%.
