Thesis (MSc)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: The codling moth, Cydia pomonella (Lepidoptera: Tortricidae), is the key pest of apples and pears worldwide. The withdrawal of certain fundamental chemicals from codling moth management spray programmes, due to concerns about human, environmental and ecosystem health, has resulted in the search for softer, more environmentally friendly, and safer control measures. Entomopathogenic nematodes (EPNs), naturally occur in the soil, and actively search for hosts. The interest in using EPNs from the families Heterorhabditidae and Stein

A possible biological origin of ARD etiology in South Africa was investigated by the dilution of replant field soil with sterilised soil.

The European House Borer (EHB) is a timber pest which attacks dead timber. This pest can cause large scale damage to wooden structures and has already spread throughout many parts of the world. The larvae usually remains undetected for many years while it busily inflicts irrevocable and substantial harm to the timber. Since the pest was first discovered in Western Australia in 2004 the Government has endeavoured to extinguish its existence. In this research, an electronic sensor has been developed in order to detect the presence of EHB larvae in timber. Only an accurate detection can allow for

Various pests are known to cause damage to this crop. The use of the sweep net for monitoring pests is a cheap, easy and quick technique. If the sweep net is suitable for the lucerne pests in South Africa, potential pest status can be determined easily and quickly and the necessary precautionary measures taken to prevent crop losses.

Horseradish peroxidase, was chosen as enzyme conjugate because it gave lower background absorbance in disease-free samples. B. cinerea reference antigen (RAg) was isolated from strawberry.

Abstract:

碩士<br>國立交通大學<br>電子研究所<br>107<br>Rice planthopper is a kind of global pest which can travel worldwide. They can survive in Taiwan even in winter and cause damage to the rice plant. In addition, some also spread disease that can cause immense loss in agriculture industry. Therefore, building a system that can detect rice planthoppers so that we can properly spray pesticide to minimize the damage is an important topic. In this thesis, we develop a rice pest monitoring and forewarning system that can locate and count the number of pests. In the first phase, we use traditional image processing tech

Abstract:

The diamondback moth (Plutella xylostella L.) is a major pest of crucifer crops worldwide. It is a particularly important problem in Southeast Asia where climatic conditions favor a short generation time and rapid proliferation. In countries such as Thailand, the diamondback moth has apparently become resistant to all classes of insecticides, even the newest ones. The first part of this thesis is the development of a computer database of all the available information on diamondback moth toxicology. About 1,550 records were extracted from more than 235 published or unpublished documents. These

The trial plots were sited within established commercial avocado orchards with trees of similar cultivar (‘Hass’), soil-type and age, located in Levubu, Limpopo, South Africa. Mixtures of cover crops were planted in the alleys of avocado orc

Abstract:

Potato leafroll virus (PLRV) causes yield and quality losses in potato. PLRV is identified by plant symptoms and serological tests such as an enzyme-linked immunosorbent assay (ELISA). A similar serological test, direct tissue blotting assay (DTBA), was used to detect and monitor PLRV movement in field-inoculated Russet Burbank plants and plant tissues from Russet Burbank and Russet Norkotah seed tubers submitted by growers for winter certification tests. DTBA was as accurate as ELISA and easier to use for detecting tuber-perpetuated PLRV in stems and petioles of plants grown from grower-submi

Abstract:

Soybean rust (SBR), caused by the fungus Phakopsora pachyrhizi Syd., is a real threat to soybean crops in South Africa. Its ability to spread rapidly and its potential to severely reduce yields have earned it the reputation as the most destructive foliar disease of soybeans. SBR has been reported in South Africa every year since its arrival in 2001. While extensive research had been done on the epidemiology and fungicide application requirements in South Africa, no work into the long term climatic vulnerability of soybean production areas to SBR had been done. This meant soybean producers do n

Abstract:

The use of pheromone-based or semiochemical lures and devices for the detection of insect pest population and monitoring in agriculture is a common practice. In many countries the use of these devices is exempt from registration requirements based on regulatory thresholds set by the relevant authorities, however, not in South Africa. The question arises whether the pheromones or semiochemicals dispensed through such devices, influence the naturally occurring compounds observed and whether a concern of toxicity and ecotoxicity is justified. A tomato field was selected in a commercial gro
