OBJECTIVE To study the relationship of remote sensing normalized differential vegetation index (NDVI) to Anopheles density and malaria incidence rate. METHODS Data of monthly average climate, environment, Anopheles density and malaria incidence rate, and remote sensing NDVI were collected from 27 townships of 10 counties in southeastern Yunnan Province from 1984 to 1993. The relationship of r...

BACKGROUND Microbiota of Anopheles midgut can modulate vector immunity and block Plasmodium development. Investigation on the bacterial biodiversity in Anopheles, and specifically on the identification of bacteria that might be used in malaria transmission blocking approaches, has been mainly conducted on malaria vectors of Africa. Vietnam is an endemic country for both malaria and Bancroftian ...

Entomological studies to determine the effect of the physical characteristics of mosquito larval breeding water bodies and reservoir water level changes on the occurrence of Anopheles mosquito larvae were conducted in two villages at Koka reservoir in central Ethiopia between August and December 2007. Of the two study villages, Ejersa is located close to the reservoir, and Kuma is 5 km away fro...

In January 1997, a bloom of the dinoflagellate Noctiluca scintillans occurred off Port Stephens, on the New South Wales (NSW) central coast. The nutrient enrichment that presumably caused the bloom was apparently unrelated to local winds. The purpose of this study is to investigate the role of the East Australian Current (EAC) in promoting nutrient-rich slope water into the euphotic zone off Po...

We have comparatively studied the dynamics of malaria transmission in the villages of Mokolo-Douvar located in the rural area with traditional agriculture and Gounougou irrigated rice area, in 2004 August and November and 2006 May and October, to assess vectors biting habits, and malaria inoculation rate and malaria parasite prevalence in cohort of children from 0 to 15 years. Mosquitoes were c...

Three taxonomic groups of Anopheles larvae were morphologically identified within the Funestus Group (Minimus Subgroup and Aconitus Subgroup) (75.63%), Maculatus Group (20.47%), and Barbirostris Group (0.57%) during a two-year period in conjunction with active malaria transmission in a village near the Thai-Myanmar border in Kanchanaburi Province, western Thailand. The remaining 3.33% of anophe...

the morphology of the adults, egg, larva and pupa of anopheles persiensis linton, sedaghat & harbach, an iranian member of the holarctic maculipennis group, was studied and compared with the morphology of the closely related and sympatric a. maculipennis meigen. anopheles persiensis was formally recognized based on dna evidence and egg morphology. the fourth member of the group, anopheles persi...

Atmospheric radiation budgets are strongly affected by the horizontal and vertical distributions of cloud systems. With the horizontal resolution of several hundred kilometers in general circulation models (GCMs), parameterization of cloud vertical overlap and horizontal inhomogeneity in radiation schemes has long been a major challenge for climate simulations (Stephens 1984; Stephens et al. 20...
