Diflubenzuron is a commonly used larvicide/biocidal substance. The present study aimed to reveal the effects of diflubenzuron on Acetylcholinesterase (AChE) enzymatic activity and liver histopathology mammalian species (rats). animals fed with various doses tissues rats were taken 10th, 20th, 25th, 45th days sixth month. AChE was measured by spectrophotometer. Tissues embedded in Araldite 502 (...

Introduction and Aim: The use of chemical pesticides has raised concerns about their safety toxicological effects on the environment, people, other species. Therefore, there is a demand for natural alternatives that are eco- friendly, biodegradable, target specific. purpose this study was to test larvicidal activity three microalgae namely, Chlorella sp., Chlorococcum Scenedesmus against Aedes ...

The 130-kilodalton mosquito larvicidal gene, cloned from Bacillus thuringiensis var. israelensis, was introduced into the cyanobacterium Agmenellum quadruplicatum PR-6 by plasmid transformation. Transformed cells synthesized 130-kilodalton delta-endotoxin protein and showed mosquito larvicidal activity. Results demonstrate a potential use of a cyanobacterium for biological control of mosquitoes.

BACKGROUND In many parts of the world, salt marshes play a key ecological role as the interface between the marine and the terrestrial environments. Salt marshes are also exceedingly important for public health as larval habitat for mosquitoes that are vectors of disease and significant biting pests. Although grid ditching and pesticides have been effective in salt marsh mosquito control, marsh...

BACKGROUND The auto-dissemination approach has been shown effective at treating cryptic refugia that remain unaffected by existing mosquito control methods. This approach relies on adult mosquito behavior to spread larvicide to breeding sites at levels that are lethal to immature mosquitoes. Prior studies demonstrate that 'dissemination stations,' deployed in mosquito-infested areas, can contam...

To monitor resistance to insecticides, bioassays were performed on 102 strains of the dengue vector Aedes aegypti (L.) from 16 countries ranging from Suriname in South America and through the chain of Caribbean Islands to the Bahamas, where the larvicide temephos and the adulticide malathion have been in use for 15 to 30 years. There was wide variation in the sensitivity to the larvicide in mos...

The existing research was conducted in Duhok city to investigate the biological impact of extracting secondary chemical compounds from punctured vine plants (Tribulus terrestris L.) on mortality all larval stages (Culex pipiens). Bioassay experiments were carried out by using solvent extraction methods and different concentrations (0.1,0.3,0.5,0.7) mg/ml. results showed that ethyl extract punct...

In Thailand, water-storage jars, barrels, drums, pails, and tanks constitute vast developmental sites for Aedes aegypti in urban, semiurban, and rural areas. Earthen water jars, cement jars, and concrete tanks constitute the greatest proportion of artificial containers where Ae. aegypti breed. This species is a major vector of the causal agents of dengue and dengue hemorrhagic fever, and vector...
