Heterorhabditis safricana n. sp. (Rhabditida: Heterorhabditidae) : a new entomopathogenic nematode from South Africa

Malan, Antoinette P. Nguyen, Khuong B. De Waal, Jeanne Y. Tiedt, Louwrence (Brill Academic Publishers, 2008-11)

During a survey for entomopathogenic nematodes in the Western Cape Province of South Africa, a new species in the genus Heterorhabditis was collected from a peach orchard. The nematode was trapped by the insect-baiting ...
Efficacy of entomopathogenic nematodes (Rhabditida : Heterorhabditidae and Steinernematidae) against codling moth, Cydia pomonella (Lepidoptera: Tortricidae) in temperate regions

De Waal, Jeanne Y. Malan, Antoinett P Addison, Matthew F. (Taylor & Francis, 2011-09)

The biocontrol potential of South African isolates of Heterorhabditis zealandica, Steinernema citrae, S. khoisanae, S. yirgalemense, and Steinernema sp., was evaluated against codling moth, Cydia pomonella. Codling moth ...
Key elements in the successful control of diapausing codling moth, Cydia pomonella (Lepidoptera: Tortricidae) in wooden fruit bins with a South African isolate of Heterorhabditis zealandica (Rhabditida: Heterorhabditidae)

De Waal, Jeanne Y. Malan, Antoinett P. Levings, John Addison, Matthew F. (Taylor & Francis, 2010-01)

The non-insecticidal control strategies currently being implemented in South African orchards for the control of codling moth, Cydia pomonella (L.) may be hampered bywooden fruit bins being infested with diapausing codling ...
Differentiation of South African potato cyst nematodes (PCN) by analysis of the rDNA internal transcribed spacer region

Knoetze, R. Malan, Antoinett P. Mouton, C. (SA ePublications, 2006)

Cysts from nematode-infested plots on eight potato farms in the Sandveld and Ceres regions of South Africa were analysed by means of rDNA-RFLP. The size of the PCR amplification products for all populations was typical for ...
Steinernema khoisanae n. sp. (Rhabditida: Steinernematidae) : a new entomopathogenic nematode from South Africa

Nguyen, Khuong B. Malan, Antoinett P. Gozel, Ugur (Brill Academic Publishers, 2006)

A new species of entomopathogenic nematode, Steinernema khoisanae n. sp. is described from South Africa. The new species is characterised by morphometrics of the infective juvenile with body length 1076 μm, narrow body ...
Entomopathogenic nematodes (Steinernematidae and Heterorhabditidae) from the southwestern parts of South Africa

Malan, Antoinett P. Nguyen, Khuong B. Addison, Matthew F. (SA ePublications, 2006)

Soil samples were collected in the southwestern parts of South Africa to obtain entomopathogenic nematodes of the families Steinernematidae and Heterorhabditidae. In total, 498 samples were randomly taken from cultivated and ...
Susceptibility of the Mediterranean fruit fly (Ceratitis capitata) and the Natal fruit fly (Ceratitis rosa) to entomopathogenic nematodes

Malan, Antoinett P. Manrakhan, Aruna (Elsevier, 2008-09)

The potential of entomopathogenic nematodes, Heterorhabditis bacteriophora, Heterorhabditis zealandica and Steinernema khoisanae, to infect pupariating larvae, pupae and adults of Ceratitis capitata and Ceratitis rosa ...
Evaluating mulches together with Heterorhabditis zealandica (Rhabditida: Heterorhabditidae) for the control of diapausing codling moth larvae, Cydia pomonella (L.) (Lepidoptera: Tortricidae)

De Waal, Jeanne Y. Malan, Antoinette P. Addison, Matthew F. (Taylor & Francis group, 2011-02)

The potential of using an entomopathogenic nematode, Heterorhabditis zealandica Poinar, together with different test mulches (pine chips, wheat straw, pine wood shavings, blackwood and apple wood chips) to control ...
Steinernema citrae n. sp. (Rhabditida: Steinernematidae), a new entomopathogenic nematode from South Africa

Stokwe, Nomakholwa F. Malan, Antoinette P. Nguyen, Khuong B. Knoetze, Rinus Tiedt, Louwrens (Koninklijke Brill NV, 2011)

During a survey for entomopathogenic nematodes in citrus orchards throughout South Africa, a new species of Steinernema was isolated from a citrus orchard on Rietkloof farm, near the town of Piketberg in the Western Cape ...
Ecophysiological traits associated with the competitive ability of invasive Australian acacias

Morris, Taryn L. Esler, Karen J. Barger, Nichole N. Jacobs, Shayne M. Cramer, Michael D. (Wiley-Blackwell, 2011-09)

Aim: We explored morphological and ecophysiological traits that enable invasive Australian acacias to compete with native species for resources (light, water and nutrients) necessary to support the substantial growth ...
Angiostoma margaretae n. sp (Nematoda: Angiostomatidae), a parasite of the milacid slug Milax gagates Draparnaud collected near Caledon, South Africa

Ross, Jenna L. Malan, Antoinette P. Ivanova, Elena S. (Springer Verlag, 2011)

Angiostoma margaretae n. sp. (Angiostomatidae) is described from the oesophagus of the slug Milax gagates Draparnaud collected near Caledon in the Western Cape Province of South Africa. The new species closely resembles ...
A landscape-scale assessment of the long-term integrated control of an invasive shrub in South Africa

Esler, Karen J. Van Wilgen, Brian W. Re Roller, Kerry S. Wood, Alan R. Van Der Merwe, Johannes H. (Springer, 2009-01)

The control of invasive alien plants often involves the integration two or more approaches, including mechanical clearing, the application of herbicides, burning, and biological control. More than one species of invasive ...
How wide is the "knowing-doing" gap in invasion biology?

Esler, Karen J. Prozesky, Heidi Sharma, Gyan P. McGeoch, Melodie (Springer, 2010)

Invasion biology is a growing discipline with clear ecological, social and economic implications. A wide range of research effort is thus required to address the invasion problem, and literature on the topic is extensive. ...
Post-dispersal fate of Acacia seeds in an African savanna

Walters, Michele Milton, Suzanne J. Somers, Michael J. Midgley, Jeremy J. (Southern African Wildlife Management Association (SAWMA), 2005-10)

African Acacia species are often major contributors to the progressive increase in the woody component of savannas, a phenomenon commonly referred to as bush encroachment. In Hluhluwe-iMfolozi Park, the numbers of adult ...
