Area(s) of Interest

Schalk Louw has spent his career focusing on two main fields of research. The first deals with the ecology and systematics of arid zone beetles. In this regard he started his research career by studying the ecological requirements of ground beetles (Tenebrionidae) in the Kalahari and Namib arid regions of south-western Africa. This was followed by studies on and specialization in the biosystematics of terrestrial weevils (Curculionidae) of sub-saharan Africa and a peculiar group of flower-loving weevils (Anthribidae) of the Afrotropical and Palaearctic regions. Underlying this interest was always the broader concept of insect - host plant interaction in general and ultimately his interest spread to this, his second research interest, within the context of new crop research and development in South Africa. Within the Insects on New Crops Programme (INCroP) at the University of the Free State, his work and that of his students concentrated on the trophic structures and general bio-ecology of insects on amaranth, pistachio, kenaf and cactus pear. He strongly advocates a ‘whole system’ approach to agroecosystem management and is particularly interested in the role vacant niches, ecological stability, landscape architecture, and spatial, temporal and scale entities play in this context. This work, in strong collaboration with Plant Pathology at the UFS, lead to the establishment of the Southern African New Crop Research Association (SANCRA), the umbrella body for new crop research in the country. Further to this, his work also formed an integral part within a multidisciplinary crop research framework that ultimately led to the establishment of the Centre for Plant Health Management (CePHMa) at the UFS.
