The Insecticide Fenvalerate Binds to NavMs Sodium Channels, Making them a Suitable Template for Modelling Structures of Housefly-Insecticide Complexes

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Modelling insecticide-binding sites in the voltage-gated sodium channel.

A homology model of the housefly voltage-gated sodium channel was developed to predict the location of binding sites for the insecticides fenvalerate, a synthetic pyrethroid, and DDT an early generation organochlorine. The model successfully addresses the state-dependent affinity of pyrethroid insecticides, their mechanism of action and the role of mutations in the channel that are known to con...

Title Methods for the Linkage-Group Determination of Insecticide- Resistance Factors in the Housefly

Synthesis and Insecticide Activity of Octahydroquinazolinone derivatives

A simple method for the synthesis of octahydroquinazolinone derivatives in the presence of BF3.SiO2 and Insecticide activity of these compounds against spodoptera litura was investigated to be comparable to commercial pyrethroid insecticides, Cypermethrin and Cyhalothrin. The structure of the isolated compounds was characterized by 1HNMR and FT-IR spectroscopy.The proposed method had some ad...

Identification and characterization of mutations in housefly (Musca domestica) acetylcholinesterase involved in insecticide resistance.

Acetylcholinesterase (AChE) insensitive to organophosphate and carbamate insecticides has been identified as a major resistance mechanism in numerous arthropod species. However, the associated genetic changes have been reported in the AChE genes from only three insect species; their role in conferring insecticide insensitivity has been confirmed, using functional expression, only for those in D...
