Abstract

The leading role in Bacillus thuringiensis B.t. research in Egypt has been taken by the National Research Centre (NRC). The present book chapter is an account of studies that have been carried out on this pathogen in Egypt and its possible role as a biological control agent. These studies included bioassay of various cultures of B.t. to detect the potent strains versus different insect species. The introduction of agro-industrial byproducts in the fermentation media have been explored for economic commercial production of the pathogen. Attempts were made to develop feeding stimulants and bait formulations aiming to overcome short environmental persistence. Novel approaches including the use of chemical additives with B.t. formulations were adopted to enhance potency against insects through biochemical reactions that occurred in the insect midgut. Reference was given to the mode of action of B.t. and its distribution. The joint action of B.t. varieties and its integration with other microbial and chemical control agents was highlighted. Investigations on the pathogen effect on various development stages of Lepidoptera are given. Pilot scale production of B.t. has been described. Studies dealing with the large scale field application of B.t. are given. Reference has been given to the current status of genetically modified technology (GM) in Egypt.
