Comparative feeding and foraging behaviour of the biocontrol agents Chilocorus spp. (Coccinellidae)
(1991)This study focuses on the effective biocontrol agent Chilocorus nigritus (Fabricius). Its behaviour and ecology were compared with other Chilocorus spp. where appropriate, to elucidate why this species is such an effective ... -
Distribution patterns of epigaeic invertebrates across Afromontane forest/grassland ecotones, in KwaZulu-Natal, South Africa.
(2000)Considered key landscape elements, ecotones play an important role in landscape ecology. In heavily fragmented, or heterogeneous landscapes, ecotones become a major, even dominant, feature. Yet, there are relatively few ... -
Dragonfly assemblage dynamics and conservation at small reservoirs in KwaZulu-Natal, South Africa.
(2004)A study of the odonate fauna was carried out at the edge of a major escarpment, in eastern South Africa, using the same methodology as has been used in the temperate regions to obtain a sub-tropical perspective. The study ... -
Grasshopper ecology and conservation in the Nama-Karoo.
(2001)This study was undertaken in the Karoo, a semi-arid grazing land in South Africa, to elucidate the interaction between grasshopper assemblages and various aspects of the Karoo landscape. It falls into four sections, the ... -
Host-parasitoid interactions of Eldana Saccharina (Lepidoptera: Pyralidae) in Cyperus Papyrus.
(1994)Since becoming a pest in graminaceous crops in Africa, the African sugarcane stalkborer Eldana saccharina Walker has been the subject of much study. Its very cryptic habits have precluded more commonly available control ... -
Resistance in maize to the maize stalk borer, Busseola fusca (Fuller) (Lepidoptera: Noctuidae)
(1989)An in depth review is given of Host Plant Resistance research on borers in general, and on B. fusca in particular. The general biology and economic importance of B. fusca are also discussed. Several aspects of the ...
