larvicical activity of bacillus thuringiensis h-14 (teknar) on mosquito larvae in ricefields, southern iran
an investigation was conducted to study the larvicidal activity of teknar (san-402-i-bacillus thuringiensis, serotype h-14, sandoz, 600 itu/mg) on mosquitolarvaein kazeroun, fars province, southern iran. five experimental plots were selected randomly in a rice field and three concentrations of teknar: .0003, .0006 and .0012 cc/1 was used. maximum larval mortality usually occurred during the fir...

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...
Alternative Mosquito Control Methods
As mosquitoes can transmit a number of diseases such as dengue fever, malaria, Japanese encephalitis, yellow fever etc., efforts have been made to control them. Control measures could be aimed at different stages of the insect in its life cycle. The measures can be classified as biological, environmental (physical) and chemical control. Integrated mosquito management approach should be adopted ...
متن کاملRNA Interference for Mosquito and Mosquito-Borne Disease Control
RNA interference (RNAi) is a powerful tool to silence endogenous mosquito and mosquito-borne pathogen genes in vivo. As the number of studies utilizing RNAi in basic research grows, so too does the arsenal of physiological targets that can be developed into products that interrupt mosquito life cycles and behaviors and, thereby, relieve the burden of mosquitoes on human health and well-being. A...
متن کاملMosquito Behaviour and Disease Control
Mosquitoes vector many important disease pathogens. Controls of mosquito-borne diseases often involve lowering the contact rate between human and vector, and killing the vector. For instance, long lasting insecticidal nets (LLINs) act on both of these levels. Unfortunately, these are at best short-term solutions as mosquitoes are known to exhibit resistance to these interventions. Physiological...
