The South African genus Austrodontura Fontana & Buzzetti of brachypterous katydids is revised. A. capensis (Walker, 1869) is redescribed and A. castletoni sp. n. from the Eastern Cape Province is described, A. raggei Fontanta & Buzzetti is considered a junior synonym of A. capensis. Acoustic behavior of A. castletoni is described.

A revision of the south African genus Neopimus Özdikmen, Demir & Türkeş, 2008 is presented. Based on revision of the type and additional material, three species are recognised. The genus Neopimus is redescribed and all species are described or redescribed and illustrated, two of them for the first time: Neopimus capensis Janák, sp. nov., from Eastern Cape Province, South Africa and N. zulu Janák, sp. nov., from KwaZulu-Natal Province, South Africa. The distribution of the genus is mapped and a key of species is presented.

The South African genus Griffiniana Karny of squamipterous to macropterous katydids (Tettigoniidae: Mecopodinae:Aprosphylini) is revised and a key to species is provided; G. duplessisae sp. n. from the Western Cape Province is de-scribed; acoustic behavior of G. capensis Karny, G. duplessisae, and G. longipes (Naskrecki) is described. The genusEwanella Naskrecki is considered a junior synonym of Griffiniana, and E. breviuscula Gorochov is synonymized with G. longipes.

ABSTRACT This paper used qualitative methodology to explore the South African government communication and land expropriation without compensation and its effects on food security using Alice town located in the Eastern Cape Province South Africa as its case study. This was done to allow the participants to give their perceptions on the role of government communication on land expropriation without compensation and its effects on South African food security. In this paper, a total population of 30 comprising of 26 small scale farmers in rural Alice and 4 employees from the Department of Agriculture (Alice), Eastern Cape, South Africa were interviewed to get their perception and views on government communications and land expropriation without compensation and its effects on South African food security. The findings of this paper revealed that the agricultural sector plays a vital role in the South African economy hence there is a great need to speed up transformation in the sector.

Growth rates of a number of Haliotis midae populations around the South African coast were studied by means of tagging. These populations ranged from the cool waters of the western coast to the more temperate environment of the eastern Cape. Standard von Bertalanffy growth curves were fitted and growth parameters derived. These ranged from 0.19 to 0.25 for K, the average rate at which L∞ is approached, and from 156 to 173 for L∞, the average theoretical maximum length. These indicate far higher growth rates than were previously published for this commercially fished species, and the reasons for this difference are discussed. The expectation that growth rates would be fastest in the warmer eastern Cape waters was not realized, there being no significant difference in growth between the Bird Island population on the eastern coast and the Robben Island population on the western coast. These new growth parameters indicate that H. midae in the commercial fishery grounds is attaining sexual maturity some four years earlier, and the minimum legal size some five years earlier, than previously considered. This has considerable significance for modelling studies presently underway. Movement of a small population of adult H. midae was studied over a three-year period, after which 47% of the original abalone were still present on the study site. Of these, 81.5% still occupied exactly the same position on the rocks. This indicates that H. midae that have located an optimum habitat, and that are not disturbed, tend not to move.

Market participation is a very crucial element among smallholder farmers through its effects on income, poverty reduction and rural economic development. Woolgrowers seek to maximise profits by sourcing for avenues for higher market value for their products. The study identifies factors which determine participation of woolgrowers in high value markets. Using stratified random sampling, data was collected from 248 woolgrowers of the National Wool Growers Association (NWGA). A Logistic regression model was used to determine the factors that influence participation of woolgrowers in high value markets. The results reveals that wool growing experience (â =.033, Sig = .000), skill acquisition (â=.728, Sig=.000) and wool price have a positive (â= .071, Sig. = .000) and significant effect on woolgrowers’ participation in the highly paid markets, while gender (â =-.412, Sig=.006) has a negative and significant effect. The findings of this study would enhance future decision and policies that would improve market accessibility and competitiveness of South African woolgrowers, thereby improving their income, food security and livelihoods.

Most haustoria in Hyobanche (Scrophulariaceae) are formed directly from the scale leaves of the extensive rhizome system and may be found on adaxial surfaces, margins, or tips of such leafy organs. The only exceptions are occasional haustoria, emerging from rhizome areas between adjacent scale leaves, and the primary haustorium. Host roots appear to be attracted to the rhizome, growing along its surface and apparently eliciting haustorial formation in adjoining parasitic tissues. The established parasite is completely rootless.

Descriptions are given of South African isolates of  Pithomyces sacchari (Speg.) M. B. Ellis, Pithomyces chartarum (Berk. Curt.) M. B. Ellis and  Pithomyces karoo  Marasas Schumann, sp. nov.  P. sacchari and P. chartarum were isolated from Medicago sativa L. seed.  P. chartarum was also isolated from dead leaves of Lolium perenne L. and  Sporobolus capensis (Willd.) Kunth. plants from artificial pastures in the eastern Cape Province.  P. karoo was isolated from stems of Gnidia polycephala (C.A. Mey.) Gilg and  Rhigozum trichotomum Burch, from the Karoo, Cape Province and from Avena sativa L. stubble collected in the Orange Free State.

On 21 March 1985, the twenty-fifth anniversary of the infamous Sharpevile incident, South African police, without provocation or warning, killed 20 unarmed black marchers at Langa in the Eastern Cape. Most were shot in the back. The outnumbered contingent of white and black police with two armoured vehicles, felt that the blacks, on their way to a funeral, would threaten the white township.The repetition of this crudest form of state violence against politicised youngsters and workers, threatened by recession after two-and-a-half decades of anti-apartheid opposition, suggests that little has changed in the repression by a minority ré. The rulers command the guns and the subordinates are left wiht no alternative but to submit or perish.
