Through basic research into genetic control of pink bollworm development, we devised a rapid immunological method of determining diapause in pink bollworm larvae — formerly a monthlong process which now requires only 24 hours. This new “ELISA”

A large, genetically diverse pool of Bemisia argentifolii BellowsPerring was collected in 1994 from different crops, and a mixed colony was established in the laboratory. Subsets of this colony were reared on cotton plants held in large Plexiglas cag

The tolerance of the beet armyworm, Spodoptera exigua (Hubner), to 3 insecticides-cyfluthrin, methomyl, and profenofos-was investigated in 2 field strains collected from Marana and Yuma, AZ. The susceptible laboratory strain was obtained in Californi

Populations of the whitefly, Bemisia tabaci collected from the Americas and the Caribbean Basin were examined for non-specific esterases and for the ability to induce characteristic phytotoxic disorders in key assay species as a means of investigatin

A strain of pink bollworm, Pectinophora gossypiella (Saunders), collected from cotton fields in Yuma, Ariz., was found to be resistant to permethrin. The strain was then selected in the laboratory to increase the level ofhomogenity for mode-of-inheri

Responses of five field-collected populations of the pink bollworm, Pectinophora gossypiella (Saunders), from Arizona and southern California, were compared with those of a standard, susceptible-laboratory strain. Field strains showed less than 2-fol

Cry1Ac protoxin (the active insecticidal toxin in both Bollgard and Bollgard II cotton [Gossypium hirsutum L.]), and Cry2Ab2 toxin (the second insecticidal toxin in Bollgard II cotton) were bioassayed against five of the primary lepidopteran pests of

Bollgard cotton is the trademark given to a number of varieties of cotton bio-engineered to produce an insecticidal protein from Bacillus thuringiensis (Bt). When produced by the modified cotton plants, this protein controls certain lepidopterous cot
