TL;DR: The cloning and functional expression of a gene involved in an insect-specific step of juvenile hormone biosynthesis is reported, and its ortholog from economically important species may be useful in the design and screening of selective insect control agents.

TL;DR: Computer simulations show that this approach works in principle against pests with recessive or dominant inheritance of resistance, and during a large-scale, four-year field deployment of this strategy in Arizona, resistance of pink bollworm to Bt cotton did not increase.

TL;DR: DNA sequencing of pink bollworm derived from resistant and susceptible field populations in India revealed eight novel, severely disrupted cadherin alleles associated with resistance to Cry1Ac, the first example of alternative splicing associated with field-evolved resistance that reduced the efficacy of a Bt crop.

TL;DR: A cDNA encoding a cytochrome P450 enzyme was isolated from a cDNA library of the corpora allata (CA) from reproductively active Diploptera punctata cockroaches as mentioned in this paper.

TL;DR: It is shown that laboratory selection of pink bollworm with Cry2Ab caused up to 420-fold cross-resistance to Cry1Ac as well as 240-fold resistance to Cry2 Ab, indicating that cross-Resistance occurs between Cry1 Ac andCry2Ab in some key cotton pests.
