Evaluation of the Impact of Genetically Modified Cotton After 20 Years of Cultivation in Mexico

Frontiers in Bioengineering and Biotechnology, 2018
For more than 20 years cotton has been the most widely sown genetically modified (GM) crop in Mexico. Its cultivation has fulfilled all requirements and has gone through the different regulatory stages.

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Effect of Manual Topping on Insect Pest Incidence and Cotton Yield

Crop Protection
Bollworms and sap-sucking insect pests are a significant constraint to cotton production in Africa. Manual topping of cotton plants, which consists of cutting off the top of the plant, i.e. the terminal bud of the main stem, is a promising alternative to chemical control by removing resources for certain pests or inducing plant defences. In this study,

Efficient Refuge policies for Bt cotton in India [PDF]

This study examined the efficient refuge policies for Bt cotton for three cotton growing regions in India. This was accomplished by developing a single-pest, dual-toxin biological model simulating bollworm resistance to the Bt toxin and synthetic ...

Insect Special Issue "Natural Substances against Insect Pests: Assets and Liabilities"

, 2020
At present, insect pests are largely controlled by synthetic pesticides. Although these are effective, their wide and heavy use has caused the rise of pest-resistant strains and negative effects on human health and on the environment, and their public ...

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

Pest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Characterization of the spectrum of insecticidal activity of Cry1B.3, Cry1Da_7, and Vip3Cb1 proteins produced by lepidopteran-protected MON 89151 cotton

Scientific Reports
The spectrum of insecticidal activity of the Cry1B.3, Cry1Da_7, and Vip3Cb1 proteins targeting lepidopteran insect pests produced by MON 89151 cotton was characterized with microbially-produced protein-incorporated diet bioassays against selected insect ...
