Two ladybeetles, Cycloneda sanguinea (L) and Harmonia axyridis Pallas, were exposed to leaf residues and topical applications of five acaricide formulations commonly used in citrus production in Florida. Dicofol was the only compound demonstrating no toxicity to larvae of either species, even at twice the recommended rate. Abamectin + petrolium oil was the most toxic material; leaf residues app...

the effects of three doses of spirodiclofen sc 240 in comparison with three registered ‎acaricides on citrus rust mite in western part of mazandaran province during period of 2003-‎‎2004 studied. the bcr design was used to assign four replications of seven treatments ‎‎(spirodiclofen sc 240 at doses 0.1, 0.18 and 0.27 millilitre in 1000cc water, fenproximate, ‎pyridaben, abamectin) including an...

Self-poisoning with organophosphate pesticides is a major health problem world-wide. Through the inhibition of acetylcholinesterase, organophosphorus poisoning is characterised by the clinical picture of acute cholinergic crisis. Other manifestations are the intermediate neurotoxic syndrome and delayed polyneuropathy. In the Western world, the occurrence of organophosphorus poisoning is less pr...

Nonthermal air plasma, which can be generated by discharge, contains large amounts of reactive oxygen species (ROS), nitrogen (RNS) and high-energy particles. The ROS RNS have strong oxidizing properties, the particles break chemical bonds in organic compounds, a process used to degrade matter such as pesticides. In present study, effects nonthermal plasma on degradation several pesticides were...

The tomato russet mite, Aculops lycopersici (Massee, 1937) (Acari: Eriophyidae) is a common pest of tomatoes. predatory Amblyseius swirskii Athias-Henriot, 1962 Phytoseiidae), can control A. populations. To integrate biological and chemical lycopersici, side effects the lethal concentrations acaricides, as predator, on should be considered. 14 acaricides for were determined under laboratory con...

BACKGROUND Atypical ocular bobbing may result from an intentional poisoning from an organophosphate compound. PHENOMENOLOGY SHOWN The patient exhibited conjugated, slow, arrhythmic, unpredictable eye movements in all directions, diagnosed as atypical ocular bobbing. EDUCATIONAL VALUE This is a rare, well-documented, clinically relevant case for medical students for correct diagnosis and app...

Organophosphate chronic toxicity has been evaluated in this study. Biological screening for organophosphate insecticide-exposed workers is mostly recommended for mixers, loaders, formulators and spraymen. We have studied 17 occupationally exposed persons to pesticides. Using Ellman's colorimetric method, their plasma cholinesterase activities have been measured. Results show that the appear...
