Specifically‚ the research aimed to: a. determine the average time the mosquito larvae were exterminated when exposed to the following treatments: the positive control which is commercial insecticide‚ the control ethanol‚ and the leaf extracts with concentrations of 30%‚ 60%‚ and 90% Vitex negundo Linn.; and‚ b. compare the span of time the mosquito larvae were exterminated when exposed to the abovementioned treatments

STUDIES Review of Related Literature On mosquito larvae‚ the major larval habitats were anthropogenic‚ resulting from human behavior. According to the Journal of Vector Ecology (2012 p37) stated that “The management of insecticide resistance among malaria vectors needs urgent attention if insecticide-treated materials can continue to be used for malaria control.” Metarhizium anisopliae‚ a fungal pathogen of terrestrial arthropods‚ kills the aquatic larvae ofAedes aegypti‚ the vector of dengue and yellow

an upper limit. My hypothesis for the larvae experiment was that the level of aerobic respiration would increase as the temperature increased and there would be an upper temperature limit. My hypothesis was proved to be correct‚ for the rate of respiration continued to increase until the upper limit was hit and the rate started to decline. There were no unexpected results from our group‚ but I noticed that group six had some unexpected data in the class larvae table. The only explanation I can make

Adult Marine organisms that have a larvae stage dependent on wind waves to move and settle in an environment‚ where they develop to adults and recruit. The Mytilus californianus has a larvae stage and as the waves break into the surface of the pier pilings in Santa Monica‚ the larvae stick to the hard substrate that the vertical columns provide. The random placement of the larvae on the pier piling is what determines how much stress and nutrients that individual larvae will receive as it develops to

Dracunculiasis “Guinea Worm” In Africa it is very difficult to find clean and sanitary essential resources when most resources are already contaminated. One of the most basic necessities a person needs to live is water‚ which can often be contaminated by the larvae of the parasite Dracunculiasis‚ also known as Guinea worm. Although African citizens may be aware of the poor prognosis when infected with Dracunculiasis‚ they are typically unaware of the parasites’ strength. I intend to analyze the location and
