Detection of Two Species of Lycus and Recognition of Dimorphism in Collection Survey from North Kordofan State/Sudan

Abstract

Lycus is the type genus of net-winged beetles in the Lycidaefamily and the tribe Lycinifound in Africa and America, they usually show sporadic distribution, but can also occur in aggregations, sometimes by the hundreds. They are considered of economic importance as they represent a potential plant pest since they typically occur on flowering plants and can be densely clustered on the inflorescences. A research project was designed for long-term monitoring of biodiversity in Sudan semi-arid ecosystem. The project was rationalized to provide a database and present indicators for ecosystem health. Three states were selected as study sites. These include Khartoum, River Nile and North Kordofan States. The Lycusspecimens were collected from North Krdofansataeusingdirect collection method. The encountered specimens were identified into least taxonomic group in the Agricultural Research Corporation. Two species were recorded and a dimorphism phenomenon was observed within the obtained lycus specimens. These findings may contribute to the understanding of its classification and ecological significance and role and initiation of possible control efforts if needed - since this insect proved to be a plant pest.
