Seven populations of Trialeurodes vaporariorum Westwood, each with a different history of exposure to insecticides, were surveyed for resistance to dichlorvos, malathion, methomyl, permethrin, and resmethrin. Six populations were resistant to methomyl, and four were resistant to resmethrin; one, with a long history of insecticide exposure, was slightly

Greenhouse Whitefly Control on Potted Chrysanthemums, Massachusetts, 1981
Insecticide and Acaricide Tests, 1982Abstract Nine insecticides were tested for control of greenhouse whiteflies. Each material was applied with a 1 liter hand-sprayer to the upper and lower leaf surfaces of the plants. Four 15 cm pots, each containing chrysanthemums, were treated with each material and placed at random on a greenhouse bench.

Stylet penetration by larvae of the greenhouse whitefly on cucumber
Entomologia Experimentalis et Applicata, 1996AbstractProbing behaviour of Trialeurodes vaporariorum (Westwood) larvae was monitored using the DC electrical penetration graph (EPG) technique on the host plant cucumber. EPGs were recorded for 16 h, simultaneously with honeydew excretion using a ‘honeydew clock’.

Greenhouse Whitefly (Homoptera: Aleyrodidae) Dispersal Under Different UV-Light Environments
Journal of Economic Entomology, 2007The greenhouse whitefly, Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae), is known to respond to UV light (UV). Field studies were conducted to improve our understanding of the behavioral effects and practical implications of using UV-blocking plastic films for the control of whitefly.
