Temperature-Dependent Development and Survival of Giant Whitefly Aleurodicus dugesii (Hemiptera: Aleyrodidae) Under Constant Temperatures.

摘要: The invasive giant whitefly Aleurodicus dugesii Cockerell (Hemiptera: Aleyrodidae) is a pest of over 300 plants species in the United States, many which are economically important ornamentals and crops. Development survival A. was assessed at seven constant temperatures ranging from 10 to 35°C provide basis for phenological forecasting assist enhancing current biological control strategies. Complete development occurred 15 28°C, with partial occurring 30°C. time differed between sexes, males developing 2 (at 25°C) 6 28°C) d faster than females. Adult highest 25°C (65.4%), rate declining rapidly other temperatures. relationship temperature evaluated using five nonlinear models (Lactin-2, Briere-1 2, Beta, LRF). Additionally, simple linear regression used calculate developmental degree-days (DDs). While all fit data well, model provided best estimated optimal (25.3°C), lower (9.9°C), upper (30.0°C) thresholds male female complete development. Using regression, DDs were calculated as 408 435 females, respectively. results this study emphasize under varied conditions.
