The usual vector for this strain is Phlebotomus argentipes. Genotyping of sand flies distributed in a VL endemic area was developed by a PCR and restriction-fragment-length polymorphism (RFLP) of 18S rRNA gene of sand fly species. Leishmaniasis is an emerging vector-borne disease in Sri Lanka. The author makes some obvious suggestions as to the necessity of excluding it from human dwellings. Search articles by 'Shalindra Ranasinghe'. had been described as a species complex of three morphologically similar species, P. argentipes s.s., Phlebotomus annandalei and Phlebotomus glaucus from India (Ilango, 2010). The current control of Phebotomus argentipes (Annandale and Brunetti), the vector of Leishmania donovani (Laveran and Mesnil), on the Indian subcontinent is base on indoor residual spraying. In 2005, India embarked on an initiative with Nepal, Bangladesh, and the World Health Organization to eliminate visceral leishmaniasis by 2015. The efficacy of this method depends, among other factors, on the timing and number of spraying rounds, which depend on the P. argentipes seasonality. Background: Visceral leishmaniasis (VL) is a deadly vector-borne disease. What are synonyms for Phlebotomus argentipes?

Leishmaniasis normally finds a mammalian reservoir in rodents and other small animals such as canids (canine leishmaniasis) and hyraxes. The highest disease burden is in the northern part of the Indian sub-continent, especially in the state of Bihar. Phlebotomus argentipes sensu lato is the well known vector of L. donovani which causes visceral leishmaniasis (VL) in the nearby South India. P. argentipes s.l. RESULTS Phlebotomus Argentipes females found more attractive towards the combined aroma of frass and conspecific eggs of pre-existing colony for the purpose of egg-deposition as the higher no. Dogs also are important reservoirs in China and in Latin America. The field-based studies on sand flies are not adequate to uncover information required for the control of the leishmaniasis through reduction of vector populations. Phlebotomus argentipes Annandale and Brunetti (Diptera: Psychodidae), the established vector for Visceral Leishmaniasis (VL) have shown some morphological variations in India and its subcontinents. The present study provides a preliminary report on the oviposition behaviour of Phlebotomus argentipes, the only vector of kala-azar (or visceral leishmaniasis) on the Indian sub-continent. The Therefore, establishment and maintenance of laboratory colonies of sand flies is an essential step in leishmaniasis research. In southern Asia, the taxonomic status of the sand fly P. (Euphlebotomus) argentipes, which transmits L. donovani, was reassessed because the variation in morphology, behavior, and distribution suggested that this was a complex of sibling species. Mymensingh is the most endemic district for kala-azar in Bangladesh. To date, Indoor Residual Spraying (IRS) campaigns have been unable to control the disease. A study was carried out in different parts of Sri Lanka including cutaneous … Background & objectives: Phlebotomus argentipes is the vector for visceral leishmaniasis in India. Early stage infections showed substantial differences in parasite load and representation of morphological forms. Laboratory colonies of several Phlebotomus species have been established for experimental study of their biology, behaviour, mutual relations with disease agents, and for testing methods of vector control. Department of Parasitology, University of Sri Jayewardenepura, Gangodawila, Nugegoda, Sri Lanka. Visceral leishmaniasis (VL), transmitted by the sand fly, Phlebotomus argentipes, is frequently reported on the Indian subcontinent where its basic ecology is largely unknown.

Phlebotomus argentipes (sand fly) is an established vector of Kala-azar or VL in Indian subcontinent. Present study deals with the comparative evaluation of attraction of female Phlebotomus argentipes (Diptera: Psychodidae), Indian Visceral Leishmaniasis vector towards the vertebrate excreta viz., cow’s manure and rabbit’s faeces through the 3-way The whole cycle takes thirty to sixty days unless the larvae diapause, when it may take four or five months. Laboratory colonies of several Phlebotomus species have been established for experimental study of their biology, behaviour, mutual relations with disease agents, and for testing methods of vector control. Leishmania donovani-induced and sand fly-transmitted leishmaniasis is a growing health problem in Sri Lanka. Abstract. Phlebotomus argentipes is an established vector of visceral leishmaniasis in India and other countries of the sub-continent (1,2). Life The insect was first described by Nelson Annandale & Enrico Adelelmo Brunetti in 1908. Here, insecticide susceptibility patterns of P. argentipes were investigated with exploration of probable underlying resistance mechanisms. One of the first accomplishments of the Commission was to establish a colony of the suspected vector, Phlebotomus argentipes, from wild-caught material, “…using a new technique for the breeding and feeding of sandflies… “ Female P. argentipes produced from that colony were fed directly on kala-azar patients in a series of 11 experiments. One fly (ARGIND3) identified as Ph. A. argentipes sensu lato deposited in Genbank. Limited knowledge on biological and behavioral characteristics of probable vector Phlebotomus argentipes hinders disease control. However, in P. argentipes … Toggle navigation. P. argentipes.
