研究了茄子上银叶粉虱（Bemisia argentifolii Bellows & Perring）在6种恒温条件（15、20、25、27、30和35°C）下的发育、存活和繁殖。从卵到成虫的发育时间在15°C下为105 d，在30°C下为14 d。所有未成熟阶段的共同发育阈值估计为12.5°C。建立了描述发育速率与温度关系的非线性生物物理模型。从该模型中推导出了15-18°C和30-35°C的低温和高温对未成熟期发育的抑制作用。在25°C下，从卵到成虫的存活率为89%;在15和35°C下，存活率分别为40%和37%。雌成虫的平均寿命为20 ℃下44 d ~ 35 ℃下10 d。B的产卵量（每雌产卵量）。argentifolii在20°C时为324，在35°C时为22。在5个恒定温度（20、25、27、30和35°C）下测定生命表参数。B的内在自然增长率（r m）。25和27°C下银合欢的最高。刀切法估算的r m值从25和27°C时的0.192到35°C时的0.073不等。种群的平均世代时间在20°C下为46 d，在30°C下为18 d。高温（35°C）的不利影响表现为发育延长、成虫寿命缩短和繁殖力降低。B的最佳温度范围。银杉种群生长在20-30 ℃。本研究的结果与B的报告进行了比较。密西西比州烟粉虱生物型B和B。亚利桑那州的烟粉虱生物型A。
The development, survivorship, and reproduction of silverleaf whitefly, Bemisia argentifolii Bellows & Perring, on eggplant at 6 constant temperatures (15, 20, 25, 27, 30, and 35°C) were studied. The development time from egg to adult varied from 105 d at 15°C to 14 d at 30°C. A common developmental threshold for all immature stages was estimated at 12.5°C. A nonlinear biophysical model describing the relationship between development rate and temperature was constructed. Low- and high-temperature inhibitions of 15-18°C and 30-35°C, respectively, for development of immature stage were derived from the model. The survivorship from egg to adult was 89% at 25°C; at 15 and 35°C, the survival percentages were 40 and 37%, respectively. The average longevity of adult females ranged from 44 d at 20°C to 10 d at 35°C. The oviposition (eggs per female) of B. argentifolii varied from 324 at 20°C to 22 at 35°C. Life table parameters were determined at 5 constant temperatures (20, 25, 27, 30, and 35°C). The intrinsic rates of natural increase (r m ) for B. argentifolii at 25 and 27°C were the highest. Jackknife estimates of r m varied from 0.192 at 25 and 27°C to 0.073 at 35°C. The mean generation times of populations ranged from 46 d at 20°C to 18 d at 30°C. The adverse effects of high temperature (35°C) were evidenced by prolonged development, shortened adult longevity and reduced fecundity. The optimal range of temperature for B. argentifolii population growth was 20-30°C. The results of this study were compared with those reported for B. tabaci biotype B in Mississippi and B. tabaci biotype A in Arizona.
