Characterisation of Sex Pheromone and Genetic Strain in Rachiplusia nu (Lepidoptera: Noctuidae) Populations Across Brazil

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Rachiplusia nu, known as the sunflower looper (SFL) and belonging to the Plusiinae subfamily, is a major defoliator of soybeans, sunflowers and other horticultural crops across southern South America. This species has recently expanded to central and northern regions of Brazil, becoming a key soybean pest.

Validation of a multi-residue method to determine deltamethrin and alpha-cypermethrin in mosquito nets by gas chromatography with electron capture detection (GC-µECD) [PDF]

open access: yes, 2013
Background: Nowadays long-lasting insecticidal mosquito nets (LNs) are frequently used around the world to protect people against malaria vectors. As they contain insecticide, laboratory control is needed to check whether the content of the active ...

The Generics Revolution and the New Economic Geography of the Global Pesticide Industry

open access: yesJournal of Agrarian Change, EarlyView.
ABSTRACT The global pesticide industry transformed from one dominated by patented products and legacy multinationals with strong manufacturing bases in the United States and EU to one dominated by generic products produced in India and China. We use proprietary market research data, data from regulatory filings, industry press and bilateral trade data ...

Impact of Environmental Exposure on Infant Sleep : The Exposome Approach

open access: yesJournal of Sleep Research, EarlyView.
This review explores how exposure to environmental pollutants during the first 1000 days of life may affect infant sleep. Evidence suggests potential links between chemical exposures and sleep disturbances, underscoring the need for more research on early‐life vulnerability and the impact of pollutants in air, diet, and breast milk.

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

open access: yesMedical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

open access: yesMedical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Full‐length coding sequence analysis of the voltage‐gated sodium channel and acetylcholinesterase genes reveals target‐site mutations and acetylcholinesterase gene duplication in housefly (Musca domestica) populations in Japanese livestock barns

open access: yesMedical and Veterinary Entomology, EarlyView.
We simultaneously analysed insecticide resistance mutations in VGSC and AChE using NGS and hybridization probe capture in houseflies collected from livestock facilities for the first time. Resistance mutations in both VGSC and AChE were detected in most wild populations, suggesting widespread distribution of resistance genes.

Comparative efficacy and studies of mode of action of minerals from diatoms against three species of filth flies

open access: yesMedical and Veterinary Entomology, EarlyView.
Mortality for diatomaceous earth was observed as early as 2 h after exposure with 50% and 90% mortality at 3.5 and 4.6 h (LT50 and LT90, respectively) for Musca domestica. The LT50 and LT90 increased when the size of the fly species increased (M. domestica to Cochliomyia macellaria to Sarcophaga bullata) and increased for all three from 50 to 70 ...
