In South Africa, it will be critically important to have a harmonised approach to IRM for FAW across the industry and across technologies. This approach should combine a clear and simple structured refuge policy which does not confuse growers between the requirements for FAW and maize stalk borers in South Africa, and which enables a high grower compliance. There are several commercialised Bt-products in South Africa which are very similar. This approach is in the best interests of the seed industry, growers and South African consumers. The new guidelines have now been published on the IRAC website.

A new fruit fly species, morphologically very similar to B. dorsalis, has been reported spreading rapidly in central Africa. This new pest is attacking mangoes, citrus and other tropical fruits. It was recently described and called Bactrocera invadens (Drew et al., 2005). Its finding in Sri Lanka confirmed its suspected Asian origin. Monitoring is ongoing in S. Africa of this aggressive insect.
