A study was made of the basic biology of subterranean Eriosoma lanigerum (Hausmann) populations in apple orchards in the Western Cape Province of South Africa. The absence of cornicles and the presence of a vulva could be used to identify 1st instar nymphs and adults respectively. Body length, body width and length of the hind femur are useful for separating 2, 3 and 4 instars. However, separation of 2 from 3 instar nymphs was very unreliable. Maximum population growth rate was at 23°C while at… Expand
The field biology of subterranean populations of the woolly apple aphid, Eriosoma lanigerum (Hausmann) (Hemiptera: Aphididae), in South African apple orchards
TLDR
There were two peaks of activity in subterranean E. lanigerum populations, one during early summer and one during autumn, and all developmental stages were recorded on the roots of apple trees throughout the year. Expand
Genetic diversity of woolly apple aphid Eriosoma lanigerum (Hemiptera: Aphididae) populations in the Western Cape, South Africa
TLDR
The low level of variation found indicated that the possibility of controlling E. lanigerum in the Western Cape using host plant resistance is favourable and that this marker may be useful for analysis of other aphid species. Expand
Laboratory Bioassays to Determine Susceptibility of Woolly Apple Aphid, Eriosoma lanigerum (Hausmann) (Hemiptera: Aphididae), to Entomopathogenic Nematodes
TLDR
It is concluded that, although S. yirgalemense showed some infection of Waa, its low mortality and inability to complete its life cycle within the host, limits its effectiveness as a biological control agent against the subterranean stages of WAA in apple orchards. Expand
Woolly Apple Aphid, Eriosoma lanigerum (Hausmann), in South Africa: Biology and Management Practices, with Focus on the Potential Use of Entomopathogenic Nematodes and Fungi
TLDR
The review represents a combination of previous and current information on management practices for the control of WAA and the potential of integrating biocontrol agents such as entomopathogenic nematodes and entomopathic fungi in a pest management system. Expand
Plant parasitic organisms in the rizosphere of apple trees in the Western Cape, with special reference to woolly apple aphid
Various aspects of the biology and ecology of woolly apple aphid, Eriosoma lanigerum, were investigated, including initial galling damage caused by E. lanigerum to the roots of apple trees, theExpand
Efficacy of entomopathogenic nematodes and fungi as biological control agents of woolly apple aphid, Eriosoma lanigerum (Hausmann) (Hemiptera: Aphididae) under South African conditions
TLDR
Research on the use of EPNs and EPF as biocontrol agents against E. lanigerum showed that they have potential to be used to control WAA, and these findings are significant, especially to those interested in integrated pest management (IPM). Expand
An initial investigation of the effects of mulch layers on soil-dwelling arthropod assemblages in vineyards
TLDR
An initial investigation into the effects of three different types of mulch on arthropod assemblages in vineyards found springtails and ants were most abundant and could be used as reference organisms for future, larger-scale studies on mulches. Expand
Review of Ecological and Conservation Perspectives on Future Options for Arthropod Management in Cape Floristic Region Pome Fruit Orchards
TLDR
Arthropod pest control techniques in Cape Floristic Region pome orchards, South Africa, that preserve biodiversity while simultaneously controlling pests, are reviewed here. Expand
Ecosystem services in orchards. A review
Arboriculture must maintain acceptable fruit production levels while preserving natural resources. This duality can be analyzed with the concept of ecosystem service. We reviewed the literature onExpand
Sustainable Biocontrol of Apple Insect Pests
TLDR
Biocontrol is an ecosystem service and as such needs to be studied holistically rather than with the more traditional reductionist science typically used in agricultural research. Expand

Prevalence of Neozygites fresenii (Entomophthorales: Neozygitaceae) on Cotton Aphids (Homoptera: Aphididae) in Arkansas Cotton
TLDR
This is the first area–wide multiyear survey for prevalence rates of Nezygites fresenii (Nowakowski) Batko, an important natural enemy of the cotton aphid, Aphis gossypii Glover, in Arkansas and showed a significant trend for a decrease in prevalence rates from south to north in both years. Expand
Growth Reduction in Nonbearing Apple Trees by Woolly Apple Aphids (Homoptera: Aphididae) on Roots
TLDR
It is concluded that woolly apple aphid populations on roots have a slight, but significant, negative effect on growth of young non bearing apple trees in the orchard environment. Expand
Dispersal behavior of the first instar nymphs of the woolly apple aphid.
TLDR
The woolly apple aphid, Eriosoma lanigerum, has been known for over 150 years as a pest of apple trees that causes a loss in tree vigor and that produces honeydew which drips on the fruit. Expand
Aerial Spores of Neozygites fresenii (Entomophthorales: Neozygitaceae): Density, Periodicity, and Potential Role in Cotton Aphid (Homoptera: Aphididae) Epizootics
TLDR
Densities of primary conidia of Neozygites fresenii (Nowakowski) Batko in the air over cotton fields during epizootics in the cotton aphid, Aphis gossypii Glover showed a clear diel periodicity. Expand
Survival of primary conidia and capilliconidia at different humidities in Erynia (subgen. Zoophthora) spp. and in Neozygites fresenii (Zygomycotina: Entomophthorales), with special emphasis on Erynia radicans
TLDR
The capilliconidia invariably survived better than the primary conidia, especially at the unsaturated atmospheres, as expressed in subsequent germination on agar medium, and addition of light to a low RH treatment significantly reduced capiliconidial survival. Expand

TLDR
The production and germination of primary conidia of Neozygites floridana as affected by temperature, humidity, and photoperiod was studied in the laboratory and high humidities (>95%) were necessary to effect germination. Expand

Larval mobility was impaired significantly in soil treated with imidacloprid at doses >6 micrograms/g of soil, and in moistened soil, larval movement was significantly impaired at 6 microgramS/G of soil. Expand
