Full Text Available O forideo P. kerteszi é uma praga que ataca principalmente as crias de abelhas sociais. As conseqüências do ataque vão desde o enfraquecimento até o extermínio total da colônia de abelhas. O objetivo deste trabalho foi a criação de uma metodologia que permita a erradicação deste parasita quando estiver atacando colônias de abelhas melipona. Três colônias de M. quadrifasciata parasitadas com o forídeo foram tratadas com solução de mel de meliponídeos ou vinagre associada ao veneno de mosca oktrine. Um frasco contendo essa solução foi colocado entre o ninho e a lixeira em colmeias do modelo Uberlândia. Uma tela de malha que não permitisse a passagem das abelhas foi colocada entre o ninho e a lixeira. Por um período de três a sete dias foram encontrados forídeos mortos dentro ou próximo à solução.The forid fly P. kerteszi is a pest that mainly attacks the brood of social bees. The consequences of this attack range from weakening to total extermination of bee colonies. The objective of the present study was to develop a methodology that would eradicate this pest when P. kerteszi is parasitizing colonies of Melipona bees. Three M. quadrifasciata colonies parasitized with the forid fly were treated with a solution of meliponid honey or vinegar in combination with the oktrine fly poison. A flask containing this solution was placed between the nest and a garbage tray separated by a mesh net that would permit the passage of forid flies but not of bees. Dead forid flies inside or close to the solution were found daily for a period of three to seven days.

Full Text Available A key is presented for the identification of the adults of 54 species of bloodsucking ceratopogonids, 51 of which are known inhabitants of Argentina, and Culicoides uruguayensis Ronderos, C. pifanoi Ortiz, and C. trilineatus Fox, which are known to occur in bordering Uruguay and Paraguay. Wing photographs are provided of females of the 45 species of Culicoides. Three new species of Culicoides Latreille from Northeastern Argentina are described and illustrated: C. austroparaensis Spinelli, C. bachmanni Spinelli, and C. williamsi Spinelli. The following six species are recorded for the first time from Argentina and/or bordering localities in Paraguay: Leptoconops brasiliensis (Lutz, C. gabaldoni Ortiz, C. ginesi Ortiz, C. pifanoi Ortiz, C. pseudocrescentis Tavares and Luna Dias, and C. trilineatus; and C. estevezae Ronderos and Spinelli is newly recorded from Misiones province of Argentina. C. lopesi Barretto is excluded from the Argentinean ceratopogonid fauna.

India's unique and highly diverse biota combined with its unique geodynamical history has generated significant interest in the patterns and processes that have shaped the current distribution of India's flora and fauna and their biogeographical relationships. Fifty four million year old Cambay amber from northwestern India provides the opportunity to address questions relating to endemism and biogeographic history by studying fossil insects. Within the present study seven extant and three fossil genera of biting midges are recorded from Cambay amber and five new species are described: Eohelea indica Stebner & Szadziewski n. sp., Gedanohelea gerdesorum Stebner & Szadziewski n. sp., Meunierohelea cambayana Stebner & Szadziewski n. sp., Meunierohelea borkenti Stebner & Szadziewski n. sp., and Meunierohelea orientalis Stebner & Szadziewski n. sp. Fossils of species in the genera Leptoconops Skuse, 1889, Forcipomyia Meigen, 1818, Brachypogon Kieffer, 1899, Stilobezzia Kieffer, 1911, Serromyia Meigen, 1818, and Mantohelea Szadziewski, 1988 are recorded without formal description. Furthermore, one fossil belonging to the genus Camptopterohelea Wirth & Hubert, 1960 is included in the present study. Our study reveals faunal links among Ceratopogonidae from Cambay amber and contemporaneous amber from Fushun, China, Eocene Baltic amber from Europe, as well as the modern Australasian and the Oriental regions. These findings imply that faunal exchange between Europe, Asia and India took place before the formation of Cambay amber in the early Eocene.
