Abstract Entomopathogenic agents are viable and effective options due to their selective action against insects but benign effects on humans the environment. The most promising entomopathogens include subspecies of Bacillus thuringiensis (Bt), which widely used for biological control insects, including mosquito vectors human pathogens. efficacy B. toxicity has led search new potentially toxic i...

Purpose: To determine the larvicidal activity of the essential oil derived from Isodon japonicus var. glaucocalyx (Maxim.) H.W.Li (Labiatae) aerial parts at flowering stage against the larvae of Aedes aegypti L. Methods: The essential oil of I. japonicus var. glaucocalyx aerial parts was obtained by hydrodistillation and analyzed by gas chromatography (GC) and gas chromaotography-mas spectromet...

Background: Transmission of Dengue Hemorrhagic Fever (DHF) is strongly influenced by the presence Aedes aegypti mosquito larvae. The most effective method for tackling DHF killing Reducing negative impact using chemical larvicides can be done through a safer alternative model, namely natural from plants. plant studied with characteristic ability to kill larvae papaya leaves. Papaya leaf extract...

The invasion of the yellow fever mosquito Aedes aegypti at Narita International Airport, Japan was detected for the first time. During the course of routine vector surveillance at Narita International Airport, 27 Ae. aegypti adults emerged from larvae and pupae collected from a single larvitrap placed near No. 88 spot at passenger terminal 2 on August 8, 2012. After the appearance of Ae. aegypt...

background : the population of mosquitoes is mainly influenced by the biotic and abiotic factors. although aedes aegypti was reported until 1960’s in the punjab, pakistan, the population has increased dramatically since 2009 and caused severe epidemics in 2011 due to heavy floods and rains. thus, this study was carried out to know the effect of biotic and abiotic factors on the population of ae...

BACKGROUND Aedes aegypti and Aedes albopictus perform an important role in the transmission of the dengue virus to human populations, particularly in the tropical and subtropical regions of the world. Despite a lack of understanding in relation to the maintenance of the dengue virus in nature during interepidemic periods, the vertical transmission of the dengue virus in populations of A. aegypt...

The use of insect pathogenic fungi is a promising alternative to chemical control against mosquitoes. Among the Hyphomycetes isolated from insects for mosquito control, the genus Aspergillus remains the least studied. In September 2005, four fungi were isolated from the Senegalese locust, Oedaleus senegalensis Kraus (Orthoptera: Acrididae), collected in Dakar, Senegal. One of these fungi, ident...

Mosquitoes host communities of microbes in their digestive tract that consist primarily of bacteria. We previously reported that Aedes aegypti larvae colonized by a native community of bacteria and gnotobiotic larvae colonized by only Escherichia coli develop very similarly into adults, whereas axenic larvae never molt and die as first instars. In this study, we extended these findings by first...

Immatures of both Aedes aegypti and Aedes albopictus have been found in water-holding bromeliad axils in Brazil. Removal of these plants or their treatment with insecticides in public and private gardens have been undertaken during dengue outbreaks in Brazil despite uncertainty as to their importance as productive habitats for dengue vectors. From March 2005-February 2006, we sampled 120 random...
