Paratransgenesis: a promising new strategy for mosquito vector control

Evaluating Paratransgenesis as a Potential Control Strategy for African Trypanosomiasis

Genetic-modification strategies are currently being developed to reduce the transmission of vector-borne diseases, including African trypanosomiasis. For tsetse, the vector of African trypanosomiasis, a paratransgenic strategy is being considered: this approach involves modification of the commensal symbiotic bacteria Sodalis to express trypanosome-resistance-conferring products. Modified Sodal...

A New Control Strategy for Controlling Isolated Microgrid

Microgrid control in isolated mode is a highly important subject area. In the present paper, a new method is used for controlling the isolated microgrids. This method was used based on the classification of the microgrids into two groups, namely fast-dynamic (battery and flywheel) and slow-dynamic (diesel generator, electrolyzer, fuel cell). For the microgrid components with fast dynamics, a se...

Camphor as a promising insecticude for control

Potential for resistance to pyriproxyfen: a promising new mosquito larvicide.

An organophosphorus-resistant strain of Culex quinquefasciatus was pressured with pyriproxyfen for 17 generations. Egg viability began declining in the F7 generation and became lower as the selection process continued; by the F17 generation egg viability was too low to proceed further. Susceptibility tests on larvae of the F5, F10, F15, and F17 generations showed no indication of increased tole...

Mosquito behavior and vector control.

Effective indoor residual spraying against malaria vectors depends on whether mosquitoes rest indoors (i.e., endophilic behavior). This varies among species and is affected by insecticidal irritancy. Exophilic behavior has evolved in certain populations exposed to prolonged spraying programs. Optimum effectiveness of insecticide-treated nets presumably depends on vectors biting at hours when mo...
