Background. The cause of dengue fevers endemicity is vector larvae density, with Aedes aegypti as the prime vector. Bandung municipality a high fever endemic area. Hence, studying habitat characteristics mosquito essential to controlling populations mosquitos.
 Purpose. This study aimed identify aedes breeding sites and relationship between risk index, hygiene maya existence incidence feve...

Nanotechnology has emerged as promising field in insect pest management. Aedes aegypti (Linnaeus) a well-known vector of dengue, chikungunya, and dengue haemorrhagic fever no commercial management practice for their eradication at the larval stage. In present study, copper sulphide one most detoxified form with biopotential properties was synthesised by standard methodology using sonochemical i...

The natural occurrence of vertical transmission of dengue viruses in Aedes albopictus (Skuse) mosquitoes was examined in the state of Kerala in southern India. Adults and larvae of Ae. albopictus collected from Kerala were screened for dengue viruses by using enzyme-linked immunosorbent assay with dengue-specific monoclonal antibodies. The possibility of the vertical transmission of dengue viru...

Phospholipase B has been found in the mosquito Culex pipiens fatigans, and some of its properties have been studied. The enzyme had a high optimum temperature (45 degrees C) and broad alkaline pH optimum (8-9). It was inactive toward diacylphospholipids, and hydrolyzed lysolecithin at a higher rate than lysophosphatidyl ethanolamine. The enzyme was heat labile, but lysolecithin protected it aga...

The three-dimensional conformation of Aea-TMOF (Aedes aegypti Trypsin Modulating Oostatic Factor), a decapeptide (YDPAPPPPPP) isolated from mosquito ovaries that inhibits the translation of many trypsin-like serine proteases, e.g. in mosquitoes, flies and lepidopterans, was used as a model for the synthesis of 10 aromatic and aliphatic organic acid and ester analogues. The organic TMOF analogue...

The copepod Mesocyclops aspericornis Daday and the larvivorous fishes Gambusia affinis (B. & G.) and Poecilia reticulata R. & B., were released into mosquito breeding sites in Tuherahera village, Tikehau atoll, French Polynesia, to control larvae of Aedes aegypti (L.), Ae.polynesiensis Marks, Culex annulirostris Skuse and Cx quinquefasciatus Say. Treatments were completed within a week, in Janu...

Mesocyclops longisetus (Thiébaud), Mesocyclops thermocyclopoides Harada, Mesocyclops venezolanus Dussart, and Macrocyclops albidus (Jurine) were tested for their effectiveness in controlling Aedes aegypti (L.) larvae in a variety of containers around homes in El Progreso, Honduras. All four cyclopoid species killed > 20 larvae per cyclopoid per d under container conditions. M. longisetus was mo...

Laboratory bioassay of the essential oil extracted from an indigenous plant, Ipomoea cairica, commonly known as 'Railway creeper', was carried out against the larvae of four vector species of mosquitoes in order to evaluate its mosquito larvicidal effect. Bioassay test revealed that the essential oil of the plant possess remarkable larvicidal properties as it could induce 100% mortality in the ...

The effect of ivermectin or diethylcarbamazine (DEC) on Wuchereria bancrofti molting from the third to the fourth larval stage (L3 to L4) was evaluated in vitro. L3 larvae were harvested from laboratory-reared Aedes togoi 2 wk after feeding upon a microfilaremic human volunteer. The larvae were kept in an artificial medium (Franke's NI medium) with 10% human serum under an atmosphere of 5% CO2 ...

A simple technique for seeking natural predators to mosquito larvae was developed. In the present study, adult backswimmers, a natural predator to mosquito larvae, were used as a model. The adult predators were fed with larvae and pupae of Aedes aegypti and tested for the presence of antigens of the mosquito larvae at 1, 2, 4, 6 and 24 hr thereafter. The test was performed using an immunologica...
