The nymphal-adult molt of the silverleaf whitefly (Bemisia argentifolii): Timing, regulation, and progress.
The developmental progress of silverleaf whitefly (Bemisia argentifolii) 3rd instars and 4th instar/pharate adults was monitored using a tracking system that had been designed to identify synchronous individuals in another species of whitefly, the greenhouse whitefly, Trialeurodes vaporariorum. When reared on greenbean under conditions of LD 16:8 and a temperature of 26 +/- 2 degrees C, the bod...
متن کاملEffects of temperature and dietary sucrose concentration on respiration in the silverleaf whitefly, Bemisia argentifolii.
A system consisting of a flow-through chamber connected to a commercial infrared gas analysis system was developed to measure homopteran respiration during feeding. Using this system, respiration rates of 202 and 206 µmol CO(2) h(-1) g(-1) (4.96 and 5.04 ml CO(2) h(-1) g(-1)) were determined for whiteflies and cotton aphids, respectively, at 25 degrees C on diets containing 15% sucrose. These r...
متن کاملLife tables and development of Bemisia argentifolii (Homoptera: Aleyrodidae) at different temperatures.
The life history of Bemisia argentifolii Bellows & Perring (Homoptera: Aleyrodidae) on tomato (Lycopersicum spp.) was studied based on the age-stage, two-sex life table at 15, 20, 25, 28, 30, and 35 degrees C. The intrinsic rate of increase (r) at these temperatures is -0.0176, 0.0667, 0.1469, 0.1611, 0.1745, and 0.0989 d(-1), respectively. The relationship among the gross reproductive rate (GR...
متن کاملAntagonism between Beauveria bassiana and imidacloprid when combined for Bemisia argentifolii (Homoptera: Aleyrodidae) control.
Imidacloprid and the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin are both used to control the whitefly Bemisia argentifolii Bellows & Perring. We tested whether the two control strategies acted additively, synergistically, or antagonistically when combined for whitefly control. We found antagonism in that B. bassiana inhibited the effectiveness of imidacloprid. When B. bassia...
متن کاملEffects of in vitro passage of Beauveria bassiana on virulence to Bemisia argentifolii.
Effects of repeated in vitro subculture on the virulence and morphological characteristics of entomopathogenic fungi appear to vary considerably among isolates and species. Some reports indicate a loss of pathogenicity in isolates of Beauveria bassiana, Metarhizium anisopliae, Nomuraea rileyi, Paecilomyces farinosus, and Verticillium lecanii (Kawakami, 1960; Schaerffenberg, 1964; Nagaich, 1973;...
