2009 journal article

<I>Bacillus thuringiensis</I> Cry1Ac Resistance Frequency in Tobacco Budworm (Lepidoptera: Noctuidae)

Journal of Economic Entomology, 102(1), 381–387.

By: C. Blanco*, D. Andow* , C. Abel *, D. Sumerford*, G. Hernandez *, J. López, L. Adams*, A. Groot n ...

author keywords: Heliothis virescens; insecticide resistance management; F-2 screen; Bt-resistance allele frequency; single-pair families
MeSH headings : Animals; Bacillus thuringiensis Toxins; Bacterial Proteins; Endotoxins; Female; Gene Frequency; Genes, Insect; Hemolysin Proteins; Insecticide Resistance / genetics; Male; Moths / genetics; Pest Control, Biological; Southeastern United States
TL;DR: The estimated resistance allele frequencies were not significantly different from a previously published estimate from 1993, and there is no evidence that H. virescens populations have become more resistant to Cry1Ac. (via Semantic Scholar)

2008 journal article

An empirical test of the F(2) screen for detection of Bacillus thuringiensis-resistance alleles in tobacco budworm (Lepidoptera : Noctuidae)

JOURNAL OF ECONOMIC ENTOMOLOGY, 101(4), 1406–1414.

By: C. Blanco*, O. Perera *, F. Gould n , D. Sumerford*, G. Hernandez *, C. Abel *, D. Andow *

author keywords: Heliothis virescens; insecticide resistance management; Cry1Ac; YHD2; single-pair family
TL;DR: The assumptions and theoretical predictions related to detection of recessive Bt-resistant alleles in field populations based on a second generation (F2) screen based on Heliothis virescens (F.) (Lepidoptera: Noctuidae) were tested. (via Semantic Scholar)

1997 journal article

Initial frequency of alleles for resistance to Bacillus thuringiensis toxins in field populations of Heliothis virescens

PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 94(8), 3519–3523.

By: F. Gould n , A. Anderson n, A. Jones n, D. Sumerford n, D. Heckel  n, J. Lopez  n, S. Micinski n, R. Leonard n, M. Laster n

author keywords: transgenic crops; insecticides; evolution
TL;DR: A single-pair mating technique greatly increases the efficiency of detecting recessive resistance alleles and could be useful in estimating resistance allele frequencies in other insects exposed to transgenic insecticidal crops or conventional insecticides. (via Semantic Scholar)
