Background & Objectives: Mosquitoes (Diptera: Culicidae) are medically considered as one of the most important species of insects in terms of disease transmission to human beings; hence, they can be vectors of remarkable diseases such as malaria, West Nile, dengue fever, yellow fever, and filariasis. This study aimed to determine the species diversity and larval habitat characteristics of mosqu...

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 ...

in order to determine the control of breeding sources of culex larvae in sewage wells by the larvicide abate, some studies were performed in the summer and autumn of 1972. in general, it was noticed in these studies that:1. the wells chosen as a control (5 wells) were active throughout the study periods and adult mosquitoes were captured plentifully. 2 in 4 sewage wells which were controlled by...

background: culex pipiens complex shows variations in morphological and biological characters including differ­ent biological forms and has medical and veterinary importance. because of having morphological variations, some­times it is not easy to separate this species from cx. quinquefasciatus and cx. torrentium . the aim of this study was to   identify the   culex pipiens complex species in o...

BACKGROUND & OBJECTIVES An efficient larvivorous fish must show a predilection for mosquito larvae in the presence of alternative preys. This study compares the feeding capacity and preference of Aphyosemion gularis exposed to different kinds of aquatic macroinvertebrates. METHODS Various prey organisms such as Anopheles larvae and pupae, Culex larvae, chironomid larvae and ostracods were eit...

The Cry48Aa/Cry49Aa binary toxin of Bacillus sphaericus was recently discovered by its ability to kill Culex quinquefasciatus mosquito larvae through a novel interaction between its two components. We have investigated the target specificity of this toxin and show it to be non-toxic to coleopteran, lepidopteran and other dipteran insects, including closely related Aedes and Anopheles mosquitoes...

background: mosquitoes lay eggs in a wide range of habitats with different physicochemical parameters. ecological data, including physicochemical factors of oviposition sites, play an important role in integrated vector management. those data help the managers to make the best decision in controlling the aquatic stages of vectors especially using source reduction. methods: to study some physico...
