Thesis (MSc)--University of Stellenbosch, 2003.<br>ENGLISH ABSTRACT: The Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is well-known as a destructive pest of fruit worldwide. Various control methods have been used against this insect. The sterile insect technique (SIT) is used as an important and successful technological method for controlling or eradicating this pest in many countries. A key factor to successfully apply SIT is dependent on the availability of efficient and economical rearing methods. Artificial insect diets with low cost bulkin

This study was aimed at investigating the potential of lactic acid fermentation in reducing myco toxin concentration in maize meal products. Maize meal was spiked separately with aflatoxin Bi, fumonism Bi, and zearalenone, and fermented for four days. During this period the concentration of each toxin and the pH of the fermented maize meal were monitored. There was a significant (p= 0.000) decrease in the concentration of all the mycotoxins, with a percentage reduction of 55-69 by the third day and 68-75 by the fourth day, respectively.

Abstract:

Plants exposed to herbivory may defend themselves by attracting the “enemies of their enemies”, a phenomenon called induced indirect defense (IID). In this process, the de novo production and emission of volatile organic compounds (VOC) by the affected plant is activated via a jasmonic acid (JA) dependent signaling cascade. VOC can be very specific for the inducing herbivore as well as for the emitting plant. Carnivores as predatory mites and parasitoid wasps use these substances as prey- or host-finding cues. If the herbivore is parasitized successfully, its development is slowed and thus the
