Experimental hut evaluation of bednets treated with an organophosphate (chlorpyrifos-methyl) or a pyrethroid (lambdacyhalothrin) alone and in combination against insecticide-resistant Anopheles gambiae and Culex quinquefasciatus mosquitoes [PDF]

open access: yes, 2005
BACKGROUND: Pyrethroid resistant mosquitoes are becoming increasingly common in parts of Africa. It is important to identify alternative insecticides which, if necessary, could be used to replace or supplement the pyrethroids for use on treated nets ...

Enhanced Recognition via Defect Engineered Amorphous Metal–Organic Framework for Sensitive and Stable Pesticide Biosensor

open access: yesAdvanced Science, EarlyView.
A defect‐engineered assembly strategy is reported for the in situ encapsulation of acetylcholinesterase (AChE) into amorphous MOF‐74, endowing the composite with superior catalytic activity and target recognition capability. Leveraging these structural advantages, a sensitive and stable biosensor is constructed for the detection of paraoxon pesticide ...

Insecticide Effects on Normal Development and Hatch of Embryos of \u3ci\u3eParatanytarsus Parthenogeneticus\u3c/i\u3e (Diptera: Chironomidae) [PDF]

open access: yes, 2017
Simple, low cost methods are needed to determine the effect of pesticides on non-target aquatic organisms. In this report, embryos of Paratanytarsus parthenogenetic us were exposed from deposition to hatch to five pesticides.

Stereoisomerism in pentaerythritol-bridged cyclotriphosphazene tri-spiranes: spiro and ansa 1,3-propanediyldioxy disubstituted derivatives [PDF]

open access: yes, 2005
Four isomeric products were isolated and purified from the reaction of 1,3-propanediol with the tetra-spirane cyclophosphazene-organophosphate compound (1): viz. the di-monospiro (2a), di-monoansa (2b) and two monospiro-monoansa derivatives (2c) and (2d).

Effects of chlorpyrifos on histopathological biomarkers of the freshwater teleost Oreochromis niloticus

open access: yesFisheries & Aquatic Life, 2023
An attempt was made to evaluate histopathological changes in the gills, liver, and kidney tissues of the freshwater teleost Oreochromis niloticus as biomarkers of chlorpyrifos toxicity. An experiment was conducted in glass aquaria with O.
