Population dynamics of mosquito larvae overwintering in southern Japan

Population Dynamics of Mosquito Larvae in Village Ponds and its Correlation with Physico-Chemical Parameters

Different standing water bodies act as breeding grounds of mosquitoes, thus responsible for the spread of diseases. A survey was conducted to study the population dynamics of mosquito larvae in three village ponds of Ludhiana district (Punjab), India. For this purpose water samples were collected at monthly intervals from July 2011 to June 2012 and larval density (LD/L) and larval density index...

population density of overwintering larvae of chilo suppressalis (lepidoptera: pyralidae) on host weeds in mazandaran province

striped rice stem borer, chilo suppressalis (lepidoptera: pyralidae) is one of the major pests in north part of iran which causes serious damage. the last larval instar overwinters in the stem of weeds around the fields. regarding the importance of weeds as overwintering habitat, population density of larvae was studied in three areas; low-, mid-, and up-lands of mazandaran province and also on...

Comparative population dynamics of mosquito-borne flaviviruses.

Among the members of the genus Flavivirus are several important human pathogens, including the dengue (DEN) and Japanese encephalitis (JE) viruses. From the analysis of gene sequence data of samples of these virus populations it is possible to infer phylogenetic relationships, which in turn can yield important epidemiological information, including their demographic history in humans. In this s...

larvicical activity of bacillus thuringiensis h-14 (teknar) on mosquito larvae in ricefields, southern iran

an investigation was conducted to study the larvicidal activity of teknar (san-402-i-bacillus thuringiensis, serotype h-14, sandoz, 600 itu/mg) on mosquitolarvaein kazeroun, fars province, southern iran. five experimental plots were selected randomly in a rice field and three concentrations of teknar: .0003, .0006 and .0012 cc/1 was used. maximum larval mortality usually occurred during the fir...
