ENGLISH ABSTRACT: Soft, serene insect songs add an intrinsic aesthetic value to the landscape. Yet these songs also
have an important biological relevance. Acoustic signals across the landscape carry a multitude
of ...
ENGLISH ABSTRACT: As the world’s human population increases, more pressure is placed on the management of natural
resources. In response, we need an efficient means of monitoring, not only the quantity of these
resources ...
Da Silva, Jessica Marie(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: An important prerequisite for evolutionary change is variability in natural populations;
however, when phenotypic and molecular rates of change differ, species delimitation is
problematic. Such discordance ...
Zylstra, Matthew J.(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: Humanity‘s growing separation from nature is central to the convergent social and ecological crises facing earth. This is both a psychological (e.g. perceptual, emotional) and physical (e.g. experiential) ...
Bam, Adrian Jock(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: The aim of the research presented in this dissertation was to investigate localised acridid outbreaks causing damage to sugarcane in Empangeni, Kwazulu-Natal, South Africa. Reports of outbreaks with ...
ENGLISH ABSTRACT: Globally, habitat transformation causes biodiversity loss, with the transformed matrix often affecting the disturbance regime in remnant natural patches. In South Africa, significant parts of the Indian ...
ENGLISH ABSTRACT: Insect pollination contributes in various degrees toward the production of a variety of
agricultural crops that ensure diversity and nutritional value in the human diet. Although
managed honeybees (Apis ...
A mass-rearing facility for Mediterranean fruit fly Ceratitis capitata (Wiedemann) was commissioned in Stellenbosch in 1999 to produce sterile male fruit flies for a sterile insect technique (SIT) project in commercial ...
Hill, Matthew P.Terblanche, John S.(PLoS, 2014-02)
Background: The invasive fruit fly, Bactrocera invadens, has expanded its range rapidly over the past 10 years. Here we aimed to determine if the recent range expansion of Bactrocera invadens into southern Africa can be ...
Malan, Antoinette P.Knoetze, R.Tiedt, L.(Cambridge University Press - CUP, 2012-12)
A new entomopathogenic nematode in the genus Heterorhabditis is described
from South Africa, from two singular isolates found 1000km from each other,
from beneath a fig tree and in a citrus orchard, respectively. ...
Le Vieux, P. D.Malan, Antoinette P.(South African Society for Enology and Viticulture, 2013-08)
Laboratory bioassays were conducted to establish the potential of entomopathogenic nematodes (EPNs) as
biocontrol agents of Planococcus ficus (Signoret). Six indigenous and two commercially available nematode
species ...
Le Vieux, P. D.Malan, Antoinette P.(South African Society for Enology and Viticulture, 2013-02)
The vine mealybug, Planococcus ficus (Hemiptera: Pseudococcidae), which is the dominant mealybug
species in South Africa, is a severe wine and table grape pest and disease vector. Their increasing
resistance to chemical ...
Kruger, D. H. M.Fourie, J. C.Malan, Antoinette P.(South African Society for Enology and Viticulture, 2013-08)
Plant-parasitic nematodes are a problem in vineyards worldwide, with some species acting as vectors of
grapevine soil-transmitted viruses. Global pressure on the use of soil-applied chemical nematicides has
led to a ...
Kapp, C.Storey, S. G.Malan, Antoinette P.(South African Society for Enology and Viticulture, 2013-07)
Soil is a non-renewable resource and supports all land-based forms of life. The sustainable production of crops is becoming progressively more critical as human populations increase and viable agricultural land decreases. ...
Ferreira, TiarinVan Reenen, CarolPages, SylvieTailliez, PatrickMalan, Antoinette P.Dicks, Leon M. T.(Society for General Microbiology, 2013-05)
The bacterial symbiont AM7T, isolated from a novel entomopathogenic nematode species of the genus Heterorhabditis, displays the main phenotypic traits of the genus Photorhabdus and is highly pathogenic to Galleria mellonella. ...
Ferreira, TiarinVan Reenen, Carol A.Endo, AkihitoSproer, CathrinMalan, Antoinette P.Dicks, Leon M. T.(Society for General Microbiology, 2013-09)
Bacterial strain SF87T, and additional strains SF80, SF362 and 106-C, isolated from the nematode Steinernema khoisanae, are non-bioluminescent Gram-reaction-negative bacteria that share many of the carbohydrate fermentation ...
De Waal, Jeanne Y.Malan, Antoinette P.Addison, Matthew F.(Taylor & Francis, 2013-12)
Adequate moisture levels are required for nematode survival and subsequent efficacy as entomopathogens. Formulation of nematodes aimed at aboveground applications may assist in maintaining such moisture levels. In this ...
Van Niekerk, S.Malan, A. P.(Cambridge University Press - CUP, 2013-11)
The citrus mealybug, Planococcus citri, is a highly destructive pest of citrus,
occurring only in the aerial parts of plants. Humidity will be one of the key
factors to consider when using entomopathogenic nematodes (EPN) ...
Ferreira, T.Malan, A. P.(Cambridge University Press - CUP, 2013-02)
Entomopathogenic nematodes (EPN) were evaluated for their potential use as
biological control agents against Phlyctinus callosus, the banded fruit weevil
(BFW). The susceptibility of larvae and adults to EPN was evaluated ...
