Health risks of Simulium (Boophthora) erythrocephalum (De Geer, 1776) in the Valencian Autonomous Region, Eastern Spain

The presence and distribution of Simulium erythrocephalum (De Geer, 1776) in the Valencian Autonomous Region is analyzed, an arthropod of medical-sanitary importance due to the marked anthropophilic characteristics exhibited and the tendency to carry out massive attacks. The increasing incidence registered in certain areas as a consequence of their hematophagy, and the meager availability of epidemiological, fauna, bioecological, and distribution data, have led to this study. A field study of 137 samplings was carried out from 2013 to the present in the 14 hydrographic basins of the Valencian Autonomous Region. The study variables were the presence or absence of preimaginal states, environm…

Black fly immature stages control efficacy (Diptera: Simuliidae) by means of Bti preparations

In the Valencian Autonomous Region, eastern Spain, for approximately 20 years, there has been a constant increase in populations of Black flies (Diptera: Simuliidae). This observation has been evidenced mainly by the medical reports from health centers and hospitals. Due to the inconvenience and damage caused by this insect to the human being, one of the municipalities most affected by the simuliids was chosen, to verify the effectiveness of Bti preparations on immature black fly states. In this article, the results of this scientific experience are presented and its high efficiency in the control of the immature populations of this harmful arthropod is corroborated.
