The distribution of Phlebotomus papatasi in Southwest Asia is thought to be highly dependent on temperature and relative humidity. A discriminant analysis model based on weather data and reported vector surveys was developed to predict the seasonal and geographic distribution of P. papatasi in this region. To simulate global warming, temperature values for 115 weather stations were increased by...
BACKGROUND In East Africa, Phlebotomus orientalis serves as the main vector of Leishmania donovani, the causative agent of visceral leishmaniasis (VL). Phlebotomus orientalis is present at two distant localities in Ethiopia; Addis Zemen where VL is endemic and Melka Werer where transmission of VL does not occur. To find out whether the difference in epidemiology of VL is due to distant composit...
Investigations on the biology of Phlebotomus papatasi were carried out under laboratory conditions at 28 +/- 2 degrees C and 80 +/- 1% RH. Fecundity of the female varied between 61 and 48 (mean 56.2 +/- 5.46) and the incubation period of eggs ranged from 7-9 (mean 7.81 +/- 0.61) days. The developmental duration of larvae and pupae varied from 24 to 31 (mean 28.57 +/- 2.71) and 9 to 11 (mean 10....
BACKGROUND Leishmania major complex is the main causative agent of zoonotic cutaneous leishmaniasis (ZCL) in the Old World. Phlebotomus papatasi and Phlebotomus duboscqi are recognized vectors of L. major complex in Northern and Southern Sahara, respectively. In Mali, ZCL due to L. major is an emerging public health problem, with several cases reported from different parts of the country. The m...
به منظور شناسایی نماتدهای انگل گیاهی مزارع سیبزمینی در استان لرستان، طی سالهای 92 -93 تعداد 70 نمونه خاک همراء با ریشه از مزارع سیبزمینی استان لرستان جمعآوری گردید. پس از استخراج و تهیه اسلایدهای میکروسکوپی دائم، با استفاده از میکروسکوپ نوری مجهز به لنز دیجیتال بر اساس ویژگیهای ریختشناسی و ریخت سنجی و با استفاده از کلیدهای معتبر،گونه نماتدها مورد مطالعه و شناسایی قرار گرفته شدند، و در صد ...
A colony was formed from eggs of a Rhodnius sp. female collected in Taquarussu, Mato Grosso do Sul, Brazil, and its specimens were used to describe R. taquarussuensissp. n. This species is similar to R. neglectus, but distinct characters were observed on the head, thorax, abdomen, female external genitalia and male genitalia. Chromosomal differences between the two species were also established.
A new species of Phlebotomine sand fly (Diptera: Psychodidae) is described from Mikea Forest in the southwest of Madagascar: Phlebotomus vincenti n. sp. It is temporarily classified in the subgenus Anaphlebotomus according to its spermathecal organization, similar to those of P. berentiensis, P. fertei and P. vaomalalae, previously classified in the subgenus Anaphlebotomus referring to on male ...
Phlebotomine sandflies of the genus Sergentomyia are widely distributed throughout the Old World. It has been suggested that Sergentomyia spp are involved in the transmission of Leishmania in India and Africa, whereas Phlebotomus spp are thought to be the sole vectors of Leishmania in the Old World. In this study, Leishmania major DNA was detected in one Sergentomyia minuta specimen that was co...
