Larva

A community based campaign for larvae reduction was organized in 3 communes Hoa Loc, An Thoi, Tan Trung of Mo Cay district, Ben Tre province in 2002. The results: the model of campaign expressed clearly the effectiveness and feasibility in larvae and mosquitos density’ reduction immediately after implementing. Furthermore, launching three to four campaigns times per year can maintain its effectiveness in long time. To gain the most effectiveness, all methods were urged implementing for changes in people’s behaviours and close combination between government, health training communication and regulations

Cutaneous larva migrans(CLM) is a creeping cutaneous eruption that results from skin invasion by the larval form of nematodes. We experienced two patients who had typical clinical findings of CLM. One patient had a history of contact with possibly contaminated fertilizer by the larva of nematotes. The other had a history of travelling to the endemic tropical areas. We report herein two cases of CLM with the literature review of the previous CLM cases in Korea.

Cutaneous larva migrans (CLM) is an uncommon cutaneous creeping eruption caused by the invasion and migration of nematode larvae into the skin. Burrowing larvae produce intensely pruritic, serpiginous, raised erythematous skin lesions. Most cases of CLM reported in Korea involved travelers returning from endemic areas with tropical or subtropical climates. We report herein a case of CLM with no history of travelling to endemic area and briefly review the relevant literature.

From 1994 to 1997, 6747 water containers have been investigated on type, volume, number of Aedes larvae living in. The result showed that 6 types of water containers being breeding sites of Ae.aegypti were drums (38.4%), concrete tanks (26.2%), jars (26%), discarded object (5.1%), aquarica (3.5%) and buckets (0.4%). Ae.aegypti was dominants species in this area (87.2% of total 47.479 Aedes larvae collected) and its key breeding places was big containers drums, tanks and jars (91.7% Ae.aegypti larvae in these containers). There was no significant change on the type of breeding site by month, but the number of larvae increases 2.2 times higher in the rainy season compared with this of the rest of the year

Mosquitoes and larvae were investigated in the forests, edges of forest and other landscapes in the jungles of U Minh Thuong and U Minh Ha during two years of 2002 and 2003. A total of 15 species (24.19% of total mosquitoes species found throughout the country and 37.5% of those in the Southern Vietnam) was found, some of which were typical species of the water forest fauma. A mingle species composition of flood plain forest fauna with presence of An. paraliae, An. umbrosus, An. separatus... and coastal brackish fauma with An. sundaucus and An. nimpe found in the study sites suggests that the forests narrowness, forest fires and other ecological damages have caused the changes of species composition and distribution of mosquitoes of forest fauna

An.Sundaucus collected from Can Gio, Ho Chi Minh City are colonized at the insectary of the National Institute of Malariology, Parasitology and Entomology and found to quickly adapt to the laboratory conditions. Since the F3, larvae have been living in the artificial brackish water with NaCl 1%. In this condition, 88% of larvae developed to pupae and 83.5% to adults. Light time 10 hours per day with 250 - 270 lux was determined to be conducive for development of larvae
