the common green lacewing is an important natural enemy used for pest control in greenhouses. it is also very common in many agricultural systems. hence, studying lethal and sublethal effects of insecticides on this predator would be useful. toxicity of endosulfan, imidacloprid and indoxacarb was assessed on 1st instar larvae of chrysoperla carnea (stephens) in laboratory. residual bioassays we...

Historic and current use pesticides (HUPs and CUPs), with respect to use in the United States and Canada, were identified in trans-Pacific and regional air masses at Mt. Bachelor Observatory (MBO), a remote high elevation mountain in Oregon's Cascade Range located in the United States, during the sampling period of April 2004 to May 2006 (n = 69), including NASA's INTEX-B campaign (spring 2006)...

The organochlorine chemicals endosulfan, dieldrin, and γ-hexachlorocyclohexane (lindane) are persistent pesticides to which people are exposed mainly via diet. Their antagonism of the γ-aminobutyric acid-A (GABA(A)) receptor makes them convulsants. They are also endocrine disruptors because of their interaction with the estrogen receptor (ER). Here, we study the effects of dieldrin, endosulfan,...

Humans are usually exposed to several pesticides simultaneously; consequently, combined actions between pesticides themselves or between pesticides and other chemicals need to be addressed in the risk assessment. Many pesticides are efficient activators of pregnane X receptor (PXR) and/or constitutive androstane receptor (CAR), two major nuclear receptors that are also activated by other substr...

Fenitrothion, endosulfan and abamectin are insecticides that affect various organs in humans and animals. The present study was conducted to investigate their cytotoxicity in isolated male rat hepatocytes. The study suggests that incubation of hepatocytes with 10 or 100 microM of each insecticide for 2h significantly decreased the cell viability. Increased leakage percentage of lactate dehydrog...

Soil salinity and the indiscriminate use of agrochemicals has significantly reduced productivity ‘Chinampas’ agroecosystem in Mexico City. Crop improvement under these stressful conditions may be achieved by soil bioremediation. In this study, we checked effects organochlorine pesticide endosulfan bioremediation with Penicillium crustosum or a citric waste on growth Phaseolus leptostachyus plan...

BACKGROUND Endosulfan has been used for over 50 years. Although most analogs have been discontinued, endosulfan has less environmental persistence. Nevertheless, pressure groups are lobbying for a worldwide ban. The reasons are: possible rodent male reproductive toxicity, other endocrine effects and cancer; human epidemiology, and exposure studies; residues appearing in remote areas of the worl...
