Effects of Sublethal Concentrations of Chlorpyrifos on Olfactory Learning and Memory Performances in Two Bee Species, Apis mellifera and Apis cerana

Sociobiology, 2017
Chlorpyrifos is a widely used organophosphorus insecticide. The acute oral 24 h median lethal dose (LD50) value of chlorpyrifos in Apis mellifera and in Apis cerana was estimated to assess differential acute chlorpyrifos toxicity in the two bee species ...

Genome-Wide Gene Expression Analysis in Response to Organophosphorus Pesticide Chlorpyrifos and Diazion in C.Elegans [PDF]

, 2010
pesticides (OPs) were originally designed to affect the nervous system by inhibiting the enzyme acetylcholinesterase, an important regulator of the neurotransmitter acetylcholine.

Variability in the dynamics of mortality and immobility responses of freshwater arthropods exposed to chlorpyrifos [PDF]

, 2010
The species sensitivity distribution (SSD) concept is an important probabilistic tool for environmental risk assessment (ERA) and accounts for differences in species sensitivity to different chemicals.

Neuroprotective Effects of Senecio brasiliensis Extract Against Chlorpyrifos-Induced Neurotoxicity and Oxidative Stress in Drosophila melanogaster. [PDF]

Basic Clin Pharmacol Toxicol
ABSTRACT Chlorpyrifos (CP) is an organophosphate insecticide that induces neurotoxicity through acetylcholinesterase (AChE) inhibition and redox imbalance, raising environmental and occupational health concerns. Plant‐derived compounds from Senecio brasiliensis, native to the Pampa biome, offer multitarget therapeutic potential.

Gene Expression Modifications by Temperature-Toxicants Interactions in Caenorhabditis elegans [PDF]

, 2011
Although organophosphorus pesticides (OP) share a common mode of action, there is increased awareness that they elicit a diverse range of gene expression responses.

Biodegradation of chlorpyrifos and its hydrolysis product 3,5,6-trichloro-2-pyridinol by a new fungal strain Cladosporium cladosporioides Hu-01. [PDF]

PLoS ONE, 2012
Intensive use of chlorpyrifos has resulted in its ubiquitous presence as a contaminant in surface streams and soils. It is thus critically essential to develop bioremediation methods to degrade and eliminate this pollutant from environments.
