Chromosome‐level genome assembly of the greenhouse whitefly (Trialeurodes vaporariorum Westwood)

Molecular Ecology Resources, 2020
The greenhouse whitefly, Trialeurodes vaporariorum Westwood, is an agricultural pest of global importance. Here we report a 787‐Mb high‐quality draft genome sequence of T. vaporariorum assembled from PacBio long reads and Hi‐C chromatin interaction maps,

Greenhouse Whitefly Control, California, 1976

Insecticide and Acaricide Tests, 1977
Abstract Fuchsia plants were in 1 gal cans on greenhouse benches. Eight treatments were applied in each test and each treatment consisted of 4 plants. The treatments were replicated 6 times. Foliar sprays were applied to the point of runoff with a Bean 5 gpm sprayer at 150 psi.

Zinnia, Greenhouse Whitefly Control, 1977

Insecticide and Acaricide Tests, 1978
Abstract The effect of six foliar applied insecticides on whitefly was evaluated by dis-persing the materials with a hand sprayer onto single plant replicates of severely infested potted zinnia seedlings grown in the greenhouse. Single leaf per replicate counts were made of juvenile whiteflies before treatment and at three, seven and 14 ...

Greenhouse Whitefly Control on Marigolds, 1990

Insecticide and Acaricide Tests, 1991
Abstract Fifteen marigold plants were grown from seed in a research greenhouse at MSU. Plants were watered by a drip irrigation system for 2 min, 4 d per wk (Sun, Mon, Wed, and Fri). Each treatment was replicated 5 times. On 21 Aug precounts were made by sampling 3 leaves from the 4 inch tall plants for all immature life stages ...

Greenhouse Whitefly Control on Tomato, 1978

Insecticide and Acaricide Tests, 1980
Abstract Thirty tomato plants 7 to 9 weeks old were placed in an isolated greenhouse containing tomato plants heavily infested with whiteflies. Twenty-four hours later the plants were moved to another isolated greenhouse free of plants and pests and any adult whiteflies on the test plants were killed with a thorough treatment of Cyanogas

A system approach to Greenhouse Whitefly population dynamics and strategy for Greenhouse Whitefly control in China

Zeitschrift für Angewandte Entomologie, 1984
AbstractThere are two weak points in the life cycle of greenhouse whiteflies within a growing season: 1. immigration from the fields into the greenhouses in autumn and 2. emigration from the greenhouses into the fields in spring. Any effort that aids in discontinuing the pest's life cycle on these two weak points will greatly reduce the pest's damage ...

Phytotoxicity and Greenhouse Whitefly Control on Poinsettias, Massachusetts Greenhouse, 1986

Insecticide and Acaricide Tests, 1987
Abstract Plants were grown in 6 inch plastic pots in 25% Metro Mix 350, 25% Terralite, and 50% sterilized field soil. Plants were pinched to 7 leaves on 9 Oct. Bracts began to color early in the second week of Nov. Insecticides were applied on 30 Sep and again on 14 Oct.

Greenhouse Whitefly Control on Poinsettias, Massachusetts, 1981

Insecticide and Acaricide Tests, 1983
Abstract Ten insecticides were tested for efficacy against greenhouse whiteflies and for phytotoxic responses of red poinsettias. Plants were grown in 15-cm pots in Metro Mix 350 and pinched to 6 leaves Oct 6. Bracts began to show color during the first week of Nov.

Inheritance of dicrotophos resistance in greenhouse whitefly

Entomologia Experimentalis et Applicata, 1995
AbstractWe studied inheritance of resistance to dicrotophos in greenhouse whitefly, Trialeurodes vaporariorum Westwood (Homoptera, Aleyrodidae). Compared with females from a field‐collected susceptible strains (S), females from a resistant strain (R) of T. vaporariorum derived from heavily treated cotton fields had a 28‐fold greater LC50 to dicrotophos

Greenhouse Whitefly Control on Poinsetta, Pennsylvania, 1978

Insecticide and Acaricide Tests, 1979
Abstract Cuttings of the Annette Hegg Diva strain of poinsetta were taken on June 29, rooted, and transplanted to 4 inch pots containing an equal mix of peat, perlite, vermiculite and mush-room casing soil. Plants were grown under natural light and no growth regulators or insecticides were applied.
