Nature and importance of subterranean insect damage to pre-harvest groundnuts
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C.F. van Eeden --- , Republic of South Africa J. B.J. van Rensburg --- Summer Grain Centre, Republic of South Africa T. C. de K. van der Linde --- Department of Zoology and Entomology, Republic of South AfricaThe nature and importance of insect damage to subterranean pre-harvest groundnuts were determined by regular sampling in commercial groundnut fields. Five categories of damage are described, viz. damage to newly planted seed, pegs, immature pods, mature pods and kernels. Both... -
Evaluation of chemical control against the insect complex of groundnuts (Arachis hypogaea L.) in the South African Highveld Region
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C.F. van Eeden --- , Republic of South Africa J. B.J. van Rensburg --- Summer Grain Centre, Republic of South Africa T. C. de K. van der Linde --- Department of Zoology and Entomology, Republic of South AfricaChemical compounds representing seed treatments, soil-applied systemic insecticides, contact and systemic corrective sprays were tested on the groundnut pest complex for three seasons in the South African Highveld Region. The efficacy of the compounds was evaluated by determining the effect... -

Response of arthropod communities to plant-community rehabilitation efforts after strip mining on the semi-arid west coast of South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Adam Steed --- Department of Conservation Ecology and Entomology, South Africa Rudi Swart --- Department of Conservation Ecology and Entomology, South Africa Marco J Pauw --- South African Environmental Observation Network (SAEON): Arid Lands Node, South Africa Francois Roets --- Department of Conservation Ecology and Entomology, South AfricaStrip mining in arid ecosystems causes extreme ecological destruction that may take decades to recover. The present study examined the effect of different plant-community rehabilitation treatments on arthropods after strip mining in the arid Namaqualand region of South Africa. Vegetation... -
Contribution to the knowledge of the macroinvertebrate fauna of the streams of Kahuzi-Biega National Park, Democratic Republic of Congo
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: MF Ngera --- Centre de Recherche en Sciences Naturelles Lwiro, Democratic Republic of Congo SU Pauls --- Senckenberg Research Institute and Natural History Museum, Germany RW Holzenthal --- Department of Entomology, USA M Bagalwa --- Centre de Recherche en Sciences Naturelles Lwiro, Democratic Republic of Congo MA Bisimwa --- Centre de Recherche en Sciences Naturelles Lwiro, Democratic Republic of Congo EM Mushayuma --- Centre de Recherche en Sciences Naturelles Lwiro, Democratic Republic of Congo DR Cammaerts --- Independent researcher, research associate of the CRSN-Lwiro, Democratic Republic of CongoThe Albertine Rift is one of Africa’s major biodiversity hotspots. However, the aquatic fauna of its western border in Democratic Republic of Congo (DRC) remains understudied and poorly characterised. Kahuzi-Biega National Park (KBNP) in DRC is a crucial link for... -
