Repellent use is one of the most effective personal protection measures in reducing bites of blood-sucking insects/ arthropods and preventing vectorborne disease transmission. Tmditionally. discovery of new repellents involves initial screening of thousands of candidates using various methods with very few successes. However. despite the obvious desirability of finding an effective mosquito rep...

Sustainability in food production is an increasingly discussed issue nowadays; therefore, demands for research that can reduce costs and ensure the quality autonomy of are relevant, with attention to use plants due their importance biodiversity. Thus, objective this was evaluate bioactivity, feeding preference, oviposition preference Miconia albicans botanical extracts at concentrations 1%, 5%,...

The search for alternative ways of controlling sericultural pests has led to the investigation of plant sources for naturally occurring compounds which may have Insect growth regulatory, feeding deterrency, repellency and confusantcy characteristics. More than 2000 species of the families Asteraceae, Fabaceae and Euphorbiaceae are known that possess some insecticidal activity. Plants with inse...

This research aims to extract neem oil from kernels of Neem seed. The extracted was used for bio-pesticide control pests. An presser machine extraction the oil. results obtained showed that an average 140ml/kg seed kernel. based insecticides are botanical pesticides safer environment and public. Various studies have shown is non-toxic birds, beneficial insects. Moreover, can be as fungicide, in...

Three biological assay procedures for repellents are currently documented in the literature: 1) ASTM E951-94, Laboratory testing of non-commercial repellent formulations on the skin. 2) ASTM E939-94, Field testing topical applications of compounds as repellents for medically important and pest arthropods. 1. Mosquitoes. 3) WHO/CTD/WHOPES/IC/96.1, Report of WHOPES informal consultation on the ev...

Slit is a repellent axon guidance cue produced by the midline glia in Drosophila that is required to regulate the formation of contralateral projections and the lateral position of longitudinal tracts. Four sequence motifs comprise the structure of Slit: a leucine-rich repeat (LRR), epidermal growth factor-like (EGF) repeats, a laminin-like globular (G)-domain, and a cysteine domain. Here we de...
