Extent of Bollworm and Sucking Pest Damage on Modern and Traditional Cotton Species and Potential for Breeding in Organic Cotton [PDF]
Sustainability, 2019 Resistance against cotton bollworm is one of the main arguments for the use of genetically modified (GM) Bt cotton around the globe. The use of GM is prohibited in organic systems and thus the remunerative value of organic cotton cultivation depends on

Insecticide and Acaricide Tests, 1988
Abstract Four individual tests were conducted to compare control of cotton bollworm (CBW) using the biological insecticides Dipel ES and DiBeta with the synthetic pyrethroid Ammo. 'G&P 3774' was planted 29 Apr and standard cultural practices were followed.

Field-Evolved Resistance to Bt Cotton: Bollworm in the U.S. and Pink Bollworm in India
Southwestern Entomologist, 2010Abstract. Some field populations of bollworm, Helicoverpa zea (Boddie), in the southeastern U.S. have evolved resistance to Bacillus thuringiensis Berliner (Bt) toxins Cry1Ac and Cry2Ab produced by transgenic cotton, Gossypium hirsutum L. Decreased susceptibility to Cry1Ac, the toxin in first-generation Bt cotton (Bollgard), was detected in laboratory ...

Status of resistance to Bt cotton in China: cotton bollworm and pink bollworm.
2015Abstract Transgenic cotton that expresses a gene derived from the bacterium Bacillus thuringiensis (Bt) has been deployed for combating the cotton pests Helicoverpa armigera and Pectinophora gossypiella since 1997 in China. The pest management tactics associated with Bt cotton have resulted in a drastic reduction in insecticide use.

Early detection of field-evolved resistance to Bt cotton in China: Cotton bollworm and pink bollworm
Journal of Invertebrate Pathology, 2012Transgenic crops producing Bacillus thuringiensis (Bt) toxins kill some major insect pests, but pests can evolve resistance and thereby reduce the effectiveness of such Bt crops. The main approach for slowing pest adaptation to Bt crops uses non-Bt host plants as "refuges" to increase survival of susceptible pests. To delay evolution of pest resistance

Studies on the Cotton Bollworms in the Sudan
Zeitschrift für Angewandte Entomologie, 1972AbstractFlower buds of cotton were never attacked by the pink bollworm, Pectinophora gossypiella Saund. The lowest mean of buds containing spiny bollworms Earias insulana (Bois) was observed in Sevin‐treated plots (0.34%), the highest (4.33%) being recorded in the control.

Bollworms, genes and ecologists
Nature, 1999A laboratory strain of pest that is resistant to a bacterial toxin engineered into cotton takes longer to develop than the non-resistant form. The implication of these new ecological research results is that the ‘refuge strategy’ of reducing the emergence of resistance to genetically modified crops may be flawed.

The Pink Bollworm of Queensland
Bulletin of Entomological Research, 1926The name Platyedra scutigera is proposed for a cotton insect of Queensland, previously reported as P. gossypiella. Its larval and pupal stages are described and notes on its bionomics and distribution are given.There are at least four distinct species of Platyedra in Australia, P.

Insecticide and Acaricide Tests, 1989
Abstract Cotton was planted 25 May at the Texas Agricultural Experiment Station, Munday. Azinphosmethyl at 0.28 kg (AI)/ha was applied 26 Jul to eliminate predators and parasites from the plots. Plots were fertilized before planting with 112 kg nitrogen/ha and irrigated 27-29 Jul.

Entomologia Experimentalis et Applicata, 1982
The effects of dietary methyl esters of cyclopropanoid and cyclopropenoid fatty acids on the growth of larvae of the pink bollworm, Pectinophora gossypiella, the bollworm, Heliothis zea and the tobacco budworm, Heliothis virescens, was investigated. The major cotton cyclopropenoid, malvalate, had an ED50 of 0.28% for larvae of P. gossypiella, 0.64% for
