BACKGROUND Anopheles culicifacies is an important vector of malaria in Southeast Asia, contributing to almost 70% of malaria cases in India. It exists as a complex of five morphologically indistinguishable species A, B, C, D and E with varied geographical distribution patterns. In India, 8% of the total population of Madhya Pradesh (Central India) contributes about 30% of total malaria cases, 6...

In most parts of sub-Saharan Africa, malaria is still the most important vector borne disease, severely affecting people ́s lives and causing economic loss. Malaria vector control to date almost exclusively relies on long lasting insecticide treated nets (LLINs) and indoor residual spraying (IRS), while other approaches such as larviciding are less implemented. Rising resistances against commonl...

Determining malaria vector species and age is crucial to measure malaria risk. Although different in ecology and susceptibility to control, the African malaria vectors Anopheles gambiae sensu stricto and An. arabiensis are morphologically similar and can be differentiated only by molecular techniques. Furthermore, few reliable methods exist to estimate the age of these vectors, which is a key p...

Urban Malaria, as a specific problem in India, was first recognized in 1969, after an indepth review of the situation of malaria in India was done by Madhok Committee. However, main malaria vector in urban areas of India is An. stephensi, which was first recognized in early part of the 20 century. Many of the local bodies carrying out antilarval operations earlier failed to continue the same du...

INTRODUCTION Malaria is a major public health problem in Nigeria, with adverse outcomes on the poor, pregnant women and children living in rural communities. A major component of current intervention in roll back malaria (RBM) initiative is vector control and insecticide-treated nets (ITNs). AIMS AND OBJECTIVE This research studied the impact of free distribution of ITNs on malaria parasitemi...

Chromosome inversions suppress genetic recombination and establish co-adapted gene complexes, or supergenes. The 2La inversion is a widespread polymorphism in the Anopheles gambiae species complex, the major African mosquito vectors of human malaria. Here we show that alleles of the 2La inversion are associated with natural malaria infection levels in wild-captured vectors from West and East Af...

OBJECTIVE To assist with strategic planning for the eradication of malaria in Henan Province, China, which reached the consolidation phase of malaria control in 1992, when only 318 malaria cases were reported. METHODS We conducted a prospective two-year study of the costs for Henan's malaria control programme. We used a cost model that could also be applied to other malaria programmes in main...

The 3-hydroxykynurenine transaminase (3-HKT) gene plays a vital role in the development of malaria parasites by participating in the synthesis of xanthurenic acid, which is involved in the exflagellation of microgametocytes in the midgut of malaria vector species. The 3-HKT enzyme is involved in the tryptophan metabolism of Anophelines. The gene had been studied in the important global malaria ...

Transmission of insect-borne diseases is shaped by the interactions among parasites, vectors, and hosts. Any factor that alters movement of infected vectors from infected to uninfeced hosts will in turn alter pathogen spread. In this paper, we study one such pathogen-vector-host system, avian malaria in pigeons transmitted by fly ectoparasites, where both two-way and three-way interactions play...
