To estimate the minimum numbers of "sweepings" for a representative sampling of larvae in a large container. 200 larvae in 4th stage were added in an 80-liter drum to carry out the experiment, in each retort was made 10 sweepings using a plastic sieve. Two hundred larvae in stage 4 were added to an 80-liter-drum and using a plastic sieve10 sweepings were carried out in each experiment replicate...

The reason for carrying out this investigati011 into the natural breeding places of the Siphuft' culina funicola fly is twofold. Firstly, because accurate knowledge of the life history of this fly is considered of importance, owing to probable connection with the spread of diseases* such as epidemic conjunctivitis and possibly yaws, and secondly, because the eye-fly ft'0111 April to October is ...

We conducted mosquito surveillance at outdoor breeding habitat in 459 households at 7 urban locations in Putrajaya, Malaysia from January to December 2010 to determine the predominant species and breeding locations. The most common species found at all locations was Aedes albopictus. Gardening utensils were the most common breeding sites. Of the 1,885 mosquito larvae specimens found, 1,774 (94....

This study aimed to determine the socio-demographic and environmental factors influencing potential breeding sites of the dengue vector in Phuket Province. Three hundred houses were recruited by cluster random sampling for larval inspection. Of all the types of water containers, a high proportion of tires and discarded items were infested by Aedes larva (42% and 32%, respectively). Due to the a...

BACKGROUND The scarce fritillary Euphydryas (Hypodryas) maturna (L.) is included in the Habitats Directive's Annexes II and IV(a). Therefore, it is crucially important to be able to define the habitat and breeding places of E.maturna in a correct and unbiased way. NEW INFORMATION Data on a previously unknown pre-diapause main host plant, the small cow-wheat (Melampyrumsylvaticum L.), of Euphy...

To study mosquito ( Diptera : Culicidae) fauna in Guilan province (Caspian sea littoral , North of Iran ), an investigation was carried out during April to December 2000. The whole set of 2478 adult specimens from 64 habitats and 6656 larvae from 127 larval breeding places was collected . Three species of the genus Culiseta were identified as follow: 1- Cs. longiareolata 2- Cs. morsitans 3- Cs....

Dengue hemorrhagic fever (DHF) is caused by the dengue virus which transmitted through bite of Aedes aegypti mosquito. Prevention DHF can be done using larvicides. Synthetic chemical larvicides are considered to have side effects in long-term use and cause environmental pollution. So we need an alternative with natural ingredients from plants, namely Japanese Papaya plants. This study aims dete...

There has been a renewed interest for larviciding during the recent decade. Although biological larvicides are considered not to be harmful non-target organisms, there is still sufficient data on effect of new long-lasting larvicide formulations such as VectoMax G combining Bacillus thuringiensis israelensis and Lysinibacullus sphaericus environment especially organisms. The present study aimed...

Few places bear as much historical and scientific significance as the breeding ground, the accumulation of stagnant water where disease-carrying insects lay their eggs. Since the turn of the twentieth century, when mosquitoes of the Anopheles genus were identified as the vector of malaria transmission, these aquatic habitats have been a key object of epidemiological research and public health i...

OBJECTIVE To investigate the breeding rate and breeding density of Carpoglyphus lactisin stored Fructus Jujubaein Anhui, China in order to provide a scientific basis for prevention of Carpoglyphus lactis (C. lactis)from spoiling the dried fruit of such category. METHODS By the breeding nature of C. lactis,we collected samples of Fructus Jujubae, which were kept over 6 months in general, from ...
