BACKGROUND Laodelphax striatellus (Fallén) is a major pest of cultivated rice and is commonly controlled in China with the organophosphate insecticides. To develop a better resistance management strategy, a chlorpyrifos-resistant strain of L. striatellus was selected in the laboratory, and its cross-resistance to other insecticides and possible mechanisms of the chlorpyrifos resistance were inv...

Insecticide resistance has been known to be prevalent in several insect species including mosquito. It has become a major problem in vector control programme due to pesticide resistance through detoxification enzymes. The present study investigated the toxicity of Ae. aegypti to organophosphates and pyrethroid insecticide and biochemical mechanisms involved in insecticide resistance in larval p...

The paper presents the results of studies on selecting a solid sorption material for absorbing liquid crop protection agents which permeate samples of protective clothing fabrics. The sorption materials were investigated and selected with an assumption that they should have a high recovery coefficient for biologically active substances, used as active ingredients in crop protection agents, at a...

A series of tests were performed in the laboratory and field, 2014-2017, assessing efficacy Trap ‘N’ Kill (TNK) (Springstar® Inc., Woodinville, WA) lethal ovitrap on Aedes albopictus adults immatures. The TNK design is to attract kill adult female mosquitoes as well any larvae that emerge over a claimed 45-day period by utilizing active ingredient dichlorvos. Cage trials demonstrate trap effect...

Abstract The present work deals with the synthesis of biodegradable hydrogel a natural polysaccharide aloe vera and vinyl monomer acrylic acid. In this synthesis, ammonium persulfate–glutaraldehyde was used as initiator-cross-linker system, acid backbone. Grafting confirmed by different techniques like SEM, FT-IR, XRD EDS. Maximum percentage swelling synthesized found to be 756%. Biodegradation...

Background: Exposure to environmental toxins such as organophosphates poses a great threat to the health of the public. In this work, we investigated the effects of continuous exposure to dichlorvos (DDVP) on kidney function and hematological parameters, and the possible antidote activity of Nigella sativa oil (NSO). Methods: This research was conducted in 2016, at The Animal Holding and Resea...

Molecular Imprinted Polymers (MIPs) have been used for recognition and binding of different compounds. We are developing MIPs to selectively bind organophosphate pesticides and toxic chemical warfare nerve agents. MIPs were made to the pesticide Dichlorvos. Control MIPs were made without the template. Dichlorvos-MIPs bound more Dichlorvos in comparison to control-MIPs. The Dichlorvos-MIPs can b...
