The interaction between Pratylenchus neglectus (Pn) and Meloidogyne chitwoodi (Mc) was investigated at soil temperatures of 15, 20, and 25 C on barley and potato. Maximum numbers of Pn and Mc penetrated barley roots at 20 C, whereas a minimum number penetrated at 15 C. Pratylenchus neglectus restricted root penetration by Mc over time and vice-versa. Population densities of each species increas...

Pratylenchus quasitereoides n. sp. is described from Western Australia. It is characterized by 2 external incisures in the head cuticle, 4 lateral incisures at mid body, stylet length 17 µm to 19 µm, V greater than 75%, PUS less than 2 body diameters long and crenate tail terminus. Molecular data confirm the separation of the new species from morphologically similar and sympatric congeners. The...

Soil-borne pathogens of the Pacific Northwest decrease yields in both spring and winter wheat. Pathogens of economic importance include Fusarium culmorum, Pratylenchus neglectus, P. thornei, and Rhizoctonia solani AG8. Few options are available to growers to manage these pathogens and reduce yield loss, therefore the focus for breeding programs is on developing resistant wheat cultivars. A reco...

during the period of april to november 1994, an investigation was carried out on fauna of phlebotominac in ilam province, west of iran. about 12000 sandflies were caught by sticky trap, light trap and aspirator from different ecological regions and were identified. these sandflies consist of 22 species (11 species from the genus phlebotomus: ph. paptasi, ph.sergenti, ph.alexandri, ph.rnajor, ph...

Phlebotomus argentipes is an established vector of visceral leishmaniasis in India and other countries of the sub-continent1,2. Phlebotomus argentipes is primarily zoophilic as it prefers animal bait seven times more than the human bait in similar situation3. However, the blood meal analysis proves that it is anthropophilic as well as zoophilic in nature4. Female P. argentipes takes blood from ...

Cutaneous leishmaniasis is one of the most important vector-borne endemic diseases in Turkey. The main objective of this study was to evaluate the influence of temperature on the developmental rates of one important vector of leishmaniasis, Phlebotomus papatasi (Scopoli, 1786) (Diptera: Psychodidae). Eggs from laboratory-reared colonies of Phlebotomus papatasi were exposed to six constant tempe...

BACKGROUND Phlebotomus perniciosus and Phlebotomus longicuspis are two phlebotomine sand fly species morphologically similar and differing in males only by the shape of the copulatory valves which are bifurcated in P. perniciosus, tip long and tapered in P. longicuspis. METHODS A count of the median coxite setae was carried out on 208 specimens from the collections of Dedet and of Parrot, ide...

Numerical analyses (correspondence analysis, ascending hierarchical classification, cladistic approach) were applied to the morphological characters of the adults of the genus Phlebotomus Rondani & Berté 1840. They confirm the reliability of the classic classifications, and also redefine the taxonomic and phylogenetic position of certain taxa. Thus, Spelaeophlebotomus Theodor 1948. Idiophleboto...

background : zoonotic cutaneous leishmaniasis (zcl) is a neglected tropical disease prevailed in many rural areas of 17 out of 31 provinces in iran. the main vector of the disease is phlebotomus papatasi and the causative agent is leishmania major in zcl foci of iran. in the current study we investigated the validity of accessory glands secre­tions as an indicator to recognize parous from nulli...

conclusions this is the first molecular report on parasite infection of both vector (p. papatas) and reservoir (t. indica) to l. major from this area. therefore, the population of both sandflies and rodents should be reduced using control methods. background leishmaniais which is one of the six most important tropical diseases in the world are in iran in 3 forms. cutaneous leishmaniasis (cl) is...
