A multi-phased study was conducted in Cambodia from 2005-2011 to measure the impact of larviciding with the bacterial larvicide, Bacillus thuringiensis israelensis (Bti), a water dispersible granule (WG) formulation on the vector, Aedes aegypti (L.) and the epidemiology. In our studies, all in-use containers were treated at 8 g/1000 L, including smaller containers and animal feeders which were ...

b a ckground: development of insecticide resistance occurred due to the continuous and misuse of synthetic insecti- cides therefore, the recent study was conducted to explore eco-friendly plant extracts that have some potential to sup- press mosquito larval population. m e t hods: who recommended mosquito larval bioassay method for insecticide was used while for the analysis of cit- rus oils fo...

BACKGROUND & OBJECTIVES Two bacterial larvicide (bio-larvicide) formulations--Bacticide and VectoBac containing viable endospores and delta endotoxin of Bacillus thuringiensis var israelensis H-14 were evaluated in 2001 for their mosquito larvicidal efficacy under the operational conditions of urban malaria control programme in Surat city, India. METHODS Larvicides were applied at the recomme...

Dengue fever, chikungunya fever and Zika virus are epidemics in Brazil that are transmitted by mosquitoes, such as Aedes aegypti or Aedes albopictus. The liquid from shells of cashew nuts is attractive for its important biological and therapeutic activities, which include toxicity to mosquitoes of the genus Aedes. The present study evaluated the effects of a mixture of surfactants from natural ...

The use of the monomolecular film Arosurf@ MSF as a mosquito larvicide was first reported by Ganett and White (1977). Since then, the efficacy of this larvicide on many mosquito species has been demonstrated in a wide variety of aquatic habitats (Levy et al. 1981, 1982; Mulla et al. 1983, Takahashi et al. 1984). Aquatic plants which occur in fresh and salt water habitats are an important source...

Background: With the rapid expansion of insecticide resistance limiting effectiveness insecticide-based vector control interventions, integrated strategies associating larviciding could be appropriate to improve current efforts. The present experimental study assesses laboratory and field efficacy larvicide VectoMax®G on Anopheline Culicine larval stages in Yaoundé. Methods: effect VectoMax®G, ...

Open marsh water management (OMWM) is a selective ponding-and-ditching technique for saltmarsh mosquito control that encourages consumption of mosquito larvae by native larvivorous fishes while eliminating or reducing larval rearing habitats. OMWM has been successfully practiced in Delaware since 1979, and after 28 years of use actively continues today. After some refinement of the state’s init...
