Biochemical mechanisms of organophosphate and pyrethroid resistance in red hairy caterpillar Amsacta albistriga (Lepidoptera: Arctiidae)

Journal of the Saudi Society of Agricultural Sciences, 2013
The red hairy caterpillar, Amsacta albistriga Walker, is an important pest of groundnut, castor and cotton in India. We determined the susceptibility of Amsacta albistriga to organophosphate and synthetic pyrethroid insecticides under laboratory ...

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

TOXICITY AND BIOCHEMICAL EFFICACY OF NOVEL PESTICIDES AGAINST Aphis craccivora Koch (HEMIPTERA: APHIDIDAE) IN RELATION TO ENZYMES ACTIVITY [PDF]

Journal of Plant Protection and Pathology, 2015
Resistance development is a key part in pest management; Experimental trials included five conventional insecticides; Mospilan, Imidor (Neonicotinoid), Actellic (Organophosphate), Chess (Azomethine pyridines) and Aphox (Carbamate) to investigate their ...

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

Journal 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 ...

Various novel insecticides are less toxic to humans, more specific to key pests

California Agriculture, 2005
A number of novel insecticides have recently been registered for insect control in agriculture. A major advantage of these new products is that they act on insect biological processes that humans do not experience, such as molting. Many

A genomic amplification affecting a carboxylesterase gene cluster confers organophosphate resistance in the mosquito Aedes aegypti: From genomic characterization to high‐throughput field detection

Evolutionary Applications, 2021
By altering gene expression and creating paralogs, genomic amplifications represent a key component of short‐term adaptive processes. In insects, the use of insecticides can select gene amplifications causing an increased expression of detoxification ...

Remaking State Power Through a Paraquat Ban in Malaysia

Journal of Agrarian Change, EarlyView.
ABSTRACT This paper examines the role of the state in its ability to enact environmental regulations. Specifically, this study investigates how Malaysian state actors changed, shifted and betrayed various, oftentimes competing interests to ban paraquat, an acutely toxic herbicide.

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

Medical 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 ...
