Reduced fitness cost accounts for the stability of a malathion‐resistant heterogeneous duplication haplotype in Ceratitis capitata field populations

Pest Management Science, EarlyView.
Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype

[Bis(2,6-diisopropylphenyl) phosphato-κO]pentakis(methanol-κO)manganese bis(2,6-diisopropylphenyl) phosphate methanol trisolvate

Acta Crystallographica Section E: Crystallographic Communications, 2018
The title compound, [Mn(C24H34O4P)(CH3OH)5](C24H34O4P)·3CH3OH, was formed in the reaction between a hydrate of a manganese(II) salt [either Mn(NO3)2(H2O)6 or MnCl2(H2O)4] with a methanol solvate of lithium bis(2,6-diisopropylphenyl) phosphate, {Li[OOP(O ...

QT Prolongation Due to Organophosphate Poisoning

, 2000
Organophosphate poisoning is a life-threatening condition. The toxicity is due to the irreversible inactivation of cholinesterase. Apart from the enhanced muscarinic and nicotinic activities, cardiac toxicity is also possible.

Integrating bioassays and transcriptomics to detect neonicotinoid resistance in Australian Bemisia tabaci MEAM1

Pest Management Science, EarlyView.
The Bemisia tabaci MEAM1 strain GR15‐1R shows partial resistance to neonicotinoids (bottom), which correlates with an increased expression of the P450 gene CYP6CM1 compared to the insecticide‐susceptible strain SU07‐1 (top). Abstract BACKGROUND Bemisia tabaci MEAM1 is a highly invasive and polyphagous pest species of agricultural and horticultural ...

Assessment of insecticide use practices in licensed pest control operators in North Carolina

Pest Management Science, EarlyView.
A statewide survey of 105 licensed North Carolina pesticide operators found ants, mosquitoes, and aphids as top target pests, pyrethroids as the dominant insecticide class (68%), and limited resistance monitoring, establishing a baseline for future insecticide resistance management and outreach.

The effects of Quercetin on memory and oxidative stress impairment due to Malathion poisoning in male Wistar rats

یافته‌های نوین در علوم زیستی, 2020
Malathion is one of the commonest type of organophosphate insecticide whose toxicity in human body is mainly considered to result from the induction of oxidative stress.

A Re-Evaluation of Olive Fruit Fly Organophosphate-Resistant Ace Alleles in Iberia, and Field-Testing Population Effects after in-Practice Dimethoate Use

Insects, 2019
The management of the olive fruit fly (Bactrocera oleae) is traditionally based upon the use of organophosphate insecticides, mainly dimethoate. In this evolutionary arms race between man and pest, the flies have adapted a pesticide resistance, implying ...
