ABSTRACT

Insecticidal effects of Agnique MMF were investigated in the coastal brackish water shrimp farms in the Tan Thuan commune, Dam Doi district of Ca Mau province in 2000. The investigations were made in terracotta jars and shrimp ponds with the surface area 30m2 and 1000m2 each. Agnique MMF was found to have a high and fast killing effect on larvae of An.sundaicus at all three testing doses of 0.3ml/m2, 0.4ml/m2 and 0.5ml/m2. Especially larvae at instars of III, IV and pupae. However, the insecticide produced a low effect on Culex sitiens killing larvae of IV ins tar and only retarding larvae of I, II, III instar. The residual effect of Agnique MMF was found to be 14 days in the terracotta jars and 6 days in the ponds. In the direct observations, Agnique MMF was found to have no negative effects on rearing shrimps

ABSTRACT

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
