Background & Aims of the Study: The aim of this study was to determine the ecology of malaria vectors in order to select the vector control masseur in the future. This study was carried out on trend of malaria cases and malaria vectors in Saravan county, Sistan & Baluchestan Province, Iran. Materials & Methods: The adult mosquitoes were collected by standard Pyrethrum space spray colle...
Three media formulated from molasses and cornsteep liquor and another media based on the basal medium formulation of IPS-82 were assessed for the growth and production of insecticidal properties of B. thuringiensis H-14 .• Bacterial powders prepared from the broth cultures were assayed against the larvae of Culex pipiens and Anopheles stephensi. A standard powder of IPS-82 was included in ...
Environmental concerns have resulted in the search for environmentally friendly natural oils for use as mosquito larvacide. Methylated coconut oil has been found to be toxic to mosquito larvae. However, the use of methylated coconut oil is limited by resource constraints in rural communities in Papua New Guinea and other Pacific Island countries where coconut oil is produced by traditional meth...
Introduction: Mosquito – borne diseases are a major public health threat in the world, including Iran. This investigation was undertaken to determine fauna, distribution, frequency and monthly activity of Anopheles larvae in Aligoudarz County. Methods: This descriptive research was carried out during April to December 1997 to study Anopheles mosquitoes fauna and seasonal activity in seven...
The Bacillus laterosporus strains 921 and 615 were shown to have toxicity for larvae of the mosquitoes Aedes aegypti, Anopheles stephensi, and Culex pipiens. The larvicidal activity of B. laterosporus was associated with spores and crystalline inclusions. Purified B. laterosporus 615 crystals were highly toxic for Aedes aegypti and Anopheles stephensi.
OBJECTIVE To investigate the larvicidal efficacy of different extracts of Ficus benghalensis L. against Culex quinquefasciatus Say, Aedes aegypti L. and Anopheles stephensi L. (Diptera: Culicidae). MATERIALS AND METHODS Larvicidal efficacy of the crude leaf extracts of Ficus benghalensis with three different solvents like methanol, benzene and acetone was tested against the early second, thir...
The objective of the present study is to determine the bioefficacy of different crude extracts of Ajuga remota against anopheline and culicine larvae. Larval susceptibility of crude carbon-tetrachloride, methanol and petroleum-ether extracts of Ajuga remota leaves was observed against the malaria vector, Anopheles stephensi and the filariasis vector, Culex quinquefasciatus. Among the extracts t...
Clostridium bifermentans serovar malaysia (C.b.m.) is highly toxic to mosquito larvae. In this study, the following aquatic nontarget invertebrates were treated with high C.b.m. concentrations (up to 1,600-fold the toxic concentration for Anopheles stephensi) to study their susceptibility towards the bacterial toxin: Planorbis planorbis (Pulmonata); Asellus aquaticus (Isopoda); Daphnia pulex (C...

Larvicidal activity of pectolinaringenin from Clerodendrum phlomidis was evaluated against Anopheles stephensi and antifeedant, larvicidal and growth inhibitory activities were evaluated against Earias vittella. Pectolinaringenin exhibited larvicidal activity of 100 and 98.24% against 2 nd and 4 th instar larvae of Anopheles stephensi at 5ppm concentration. It exhibited LC50 values of 0.35 and ...
