Water samples were collected from breeding sites of species of the Simulium (Edwardsellum) damnoslm complex in Upper Volta, Liberia and Cameroon during the dry season; and in Tanzania and Kenya at… Expand
Contribution to the sand fly fauna (Diptera: Phlebotominae) of Rio Grande do Sul, Brazil and Leishmania (Viannia) infections.
American cutaneous leishmaniasis (ACL) is endemic in the State of Rio Grande do Sul, Brazil. As reports of nearby hospitals suggest, the Parque Estadual do Turvo seems to serve as a source for the… Expand
Development of Rhodnius prolixus (Hemiptera: Reduviidae) under constant and cyclic conditions of temperature and humidity.
Development of Rhodnius prolixus after eclosion until the adult stage was studied at constant temperatures (T), 15, 20, 25, 28, 35 C, and relative humidities (RH), 75, 86 and 97%, and fluctuating… Expand
Cytotaxonomic differentiation of Wilhelmia equina (Linné, 1747) and Wilhelmia lineata (Meigen, 1804) (Diptera: Simuliidae)
In most cases the larvae of Wilhelmia equina and W. lineata cannot be distinguished by using classical morphological features. The morphological characteristics of the salivary gland polytene… Expand

When exceptionally low rainfall resulted in the drying out of some 'permanent' streams containing the immature stages of Simulium neavei complex species, the fate of the larvae and their associated… Expand
Present progress towards the laboratory colonization of African Simuliidae (Diptera).
The laboratory colonization of African simuliids would facilitate critical work on many aspects of their biology and onchocerciasis vectors could be studied away from natural breeding-sites. In… Expand

The history of onchocerciasis control in Africa and the genesis of the WHO Onchocerciasis Control Programme in West Africa (OCP) are briefly reviewed. The importance of experience gained in… Expand
Mögliche Auswirkungen von Klimaveränderungen auf die Ausbreitung von primär humanmedizinisch relevanten Krankheitserregern über tierische Vektoren sowie auf die wichtigen Humanparasiten in Deutschland
The effect of NeemAzal on Aedes aegypti (Diptera: Culicidae).
The effect of NeemAzal (TRIFOLIO-M GmbH, Lahnau), a neem seed kernel extract, on larvae of Aedes aegypti was tested. Second, third and fourth instar larvae were reared in water containing different… Expand
The effect of fluctuating temperature and humidity on the longevity of starved Rhodnius prolixus (Hem., Triatominae)
Abstract: The survival potential of newly emerged unfed and starved Rhodnius prolixus nymphs was studied under various regimes of fluctuating temperatures between 15 and 35 °C and humidities between… Expand
