Abstract Physics is a science that has developed valuable contributions to the understanding of different phenomena; in particular, concept dynamic system originates Newtonian mechanics; allows predictions phenomena are changing over time. The evolution rule an implicit relation can be given by differential equation; our goal use systems problem global importance, such as malaria. This potentia...

Chemical insecticides are the primary means to control mosquitoes, and mosquito control programs must regularly monitor for resistance of mosquito vectors to commonly used insecticides to ensure the efficacy and sustainability of active ingredients. We performed insecticide resistance bioassays to test the susceptibility of field-collected mosquitoes in central New Jersey to 1 larvicide (temeph...

The control of mosquito populations with insecticide treated bed nets and indoor residual sprays remains the cornerstone of malaria reduction and elimination programs. In light of widespread insecticide resistance in mosquitoes, however, alternative strategies for reducing transmission by the mosquito vector are urgently needed, including the identification of safe compounds that affect vectori...

Mosquitoes are vectors of the major diseases public health concern in World. These include malaria, dengue fever, lymphatic filariasis, yellow chikwungunya and recently zika virus causing morbidity mortality tropical sub-tropical regions world. The success malarial vector control depends on susceptibility Anopheles mosquitoes to insecticides. One locally made insecticide (Ota Pia-Pia), syntheti...

OBJECTIVE Evaluating the efficacy of two pyrethroid insecticides on Aedes aegypti, thereby providing useful information for decision-making in controlling dengue. METHODS The effect on A. aegypti of ultra low volume (ULV) highcis-Permethrin (Depe) and ss-cypermethrin pyrethroids in a smoke-generating formulation (Bolate) was evaluated in 16 blocks in the town of Puerto Leguizamo, Putumayo, be...

<p><em>The use of cypermethrin insecticide is one the strategies in vector control that has been carried out by Port Health Office Karimun Regency. It necessary to evaluate insecticides because threat resistance controlling dengue hemorrhagic fever. The purpose this study was determine Aedes albopictus mosquitoes Meral area at This type research a quasi-experimental with posttest on...

background : mosquitoes are considered as the vectors of dirofilariasis and some vector borne disease in iran. the objective of this study was to determine the susceptibility level of the vectors to various insecticides recommended by who for any control measures in an endemic area in northwestern iran. methods : mosquito larval and adult collections were carried out using different methods pro...

In the mosquito Culex pipiens, insecticide resistance genes alter many life-history traits and incur a fitness cost. Resistance to organophosphate insecticides involves two loci, with each locus coding for a different mechanism of resistance (degradation vs. insensitivity to insecticides). The density of intracellular Wolbachia bacteria has been found to be higher in resistant mosquitoes, regar...

BACKGROUND The control and prevention of dengue largely depends on vector control measures, environmental management, and personal protection. Dengue control programmes are facing great challenges due to development of insecticide resistance among vector mosquitoes. Information on susceptibility status to different insecticides is important for national programmes to formulate vector control st...

five organo-phosphorous compounds were tested against lab-bred and wild caught larvae of ano pliclcs stcphclisi nrysorcnsis at the kazeroun medical research station, southern iran, during may-june, 1974. this study showed that as the larvae grew their tolerance to the insecticides tested increased up to 5 times more than that of day-old larvae. when iate 3rd and early 4th instal' larvae of wild...
