Chemical composition of four essential oils and their adulticidal, repellence, and field oviposition deterrence activities against Culex pipiens L. (Diptera: Culicidae).

Effective mosquito repellents can limit the transmission of vector-borne diseases to humans. Consequently, there is an urgent need to develop mosquito control strategies that prioritize eco-friendly and cost-effective repellents. Essential oils (EOs) have enormous potential for mosquito repellency.

Antimosquito Activity of a Titanium-Organic Framework Supported on Fabrics.

Waste swamps, stagnant water, and poor hygiene practices result in the proliferation of mosquitoes that may cause transmissible and infectious diseases such as malaria, typhoid, cholera, and Zika virus sickness. It has been shown that composites of the traditional natural fibers cotton, viscose, and linen and a Ti-bearing metal-organic framework, NH-MIL-125, are very effective against mosquitoes in the absence of any conventional insecticides. In our study, prior to coating with NH-MIL-125 crystals, the fabrics were modified with 3-glycidyloxypropyltrimethoxysilane.

Toxicological studies for some agricultural waste extracts on mosquito larvae and experimental animals.

Objective: To evaluate some agricultural waste extracts as insecticide and their effects on enzyme activities in liver and kidney of male mice.

Methods: The insecticidal activity of five tested compounds (one crude extract and 4 waste compounds) was bioassay against the 3rd instars of the Culex pipiens (Cx. pipiens) larvae in the laboratory.
