Bemisia tabaci (Homoptera: Aleyrodidae): Development, Oviposition, and Longevity in Relation to Temperature1

Abstract
Development of Bemisia tabaci Genn. was observed on seedling cotton plants in constant temperature cabinets. The duration of the egg stage varied from 22.5 days at 16.7°C to 5.0 days at 32.5°C, whereas eggs failed to hatch at a constant 36.0°C. The total development time from egg to adult varied from 65.1 days at 14.9°C to 16.6 days at 30.0°C. Development took longer, and there was evidence of aestivation at temperatures fluctuating between 27° and 43°C. Development rates were similar to those on other host plants recorded in the literature. Peak emergence of adults occurred between 6 and 9 a.m. The average number of eggs laid per female was 81 at 26.7°C and 72 at 32.2°C. Males lived an average of 7.6 and 11.7 days, and females lived an average of 8.0 and 10.4 days, at 26.7 and 32.2°C, respectively.
