in order to find a taxonomical difference between the larvae of a. stephensi and a. superpietus, 100 larvae of each species were taken and the number of branchings of the middle prothoracic hairs in the direction of the outer prothoracic hair were counted. the means found for a. stephensi and a. superpictus are 11.20 and 13.11 respectively, which are statistically significant. further studies o...

BACKGROUND Biting habit of mosquitoes plays an important role in the epidemiology of mosquito-borne diseases. Mosquitoes use a set of elaborate sensory modalities to find their preferred hosts by exploiting cues emanating from a nearby host. It has been suggested that the chemical profile of skin can provide further support for anthropophilic mosquito species to find their suitable hosts. This ...

BACKGROUND & OBJECTIVES Development of insect resistance to synthetic pesticides, high operational cost and environmental pollution have created the need for developing alternative approaches to control vector-borne diseases. In the present study, larvicidal activity of flavonoid extracts of different parts of Vitex negundo (Linnaeus) and Andrographis paniculata (Nees) have been studied against...

Anopheline mosquitoes are the primary vectors of parasites in the genus Plasmodium, the causative agents of malaria. Malaria parasites undergo a series of complex transformations upon ingestion by the mosquito host. During this process, the physical barrier of the midgut epithelium, along with innate immune defenses, functionally restrict parasite development. Although these defenses have been ...

BACKGROUND & OBJECTIVE Vector control, using agents of chemical origin, continues to be practiced in the control of vector borne diseases. However, due to some drawbacks including lack of selectivity, environmental contamination, and emergence and spread of vector resistance, development of natural products for vector control has been a priority in this area. In the present study we evaluated t...

In mosquito control programs, insecticides of botanical origin have the potential to eliminate eggs, larvae, and adults. So, the larvicidal, ovicidal, and oviposition-deterrent activities of petroleum ether and ethyl acetate extracts of the leaves of Eugenia jambolana, Solidago canadensis, Euodia ridleyi, and Spilanthes mauritiana were assayed against the three vector mosquito species, namely A...

OBJECTIVE To evaluate the larvicidal and pupicidal potential of the methanolic extracts from Moringa oleifera (M. oleifera) plant seeds against malarial vector Anopheles stephensi (A. stephensi) mosquitoes at different concentrations (20, 40, 60, 80 and 100 ppm). METHODS M. oleifera was collected from the area of around Bharathiar University, Coimbatore. The dried plant materials were powdere...

b a ckground: application of plant derivatives have been suggested as alternative sources for mosquito control. m ethods: the root essential oil and methanol extract of c ionura erecta (l.) griseb was tested under laboratory conditions for larvicidal and skin repelleny activities against anopheles stephensi . the chemical compositions of essential oils were analyzed using gas chromatography- ma...

backgrand: the genus ajuga , belongs to lamiaceae family, is one of the exclusive subspecies in the flora of iran. the plants of this genus are used traditionally for treatment of joints pain, gout, jaundice, and as insecticide. methods: larvicidal activity of methanol 80% extract and partition fractions of hexane, chloroform, and ethyl acetate obtained from aerial parts of ajuga chamaecistus s...
