The aim of this website is to provide a broad overview of the use of microbial biopesticides, including their social importance, advantages, limitations and successes. Conclusion In conclusion, microbial biopesticides are a valuable pest management tool, ideal for use in integrated pest management. Control of agricultural pests has been the focus of this review but microbial biopesticides could also be used to control human and veterinary disease insect vectors (e.g. mosquitoes that spread malaria, yellow fever and filariasis) (Nicholson, 2007). As pest resistance and consumer pressure continue to result in chemical pesticide product withdrawal, the market for microbial biopesticides will grow. Awareness of their benefits is increasing but policy makers need to review the regulation and registration process further to remove the barrier preventing their commercialisation.  A strong marketing strategy needs to be devised to increase sales of microbial biopesticides, particularly as they face competition from transgenic crops and modern environmental chemical pesticides. The title microbial biopesticides may be associated by the public with negative connotations therefore it would be helpful to change the name. Pressure is being put on use of inundative agents with a relatively wide host range, longer shelf life and increased environmental persistence. This however is not wise. If the agent is too persistent the manufacturer selling it would not have repeat sales so would make little profit. Furthermore, although reduced selectivity of an agent would increase the market size, it would also increase death of non-target taxa. All in all, a meta-analysis of the long term effects and possible risks on a large area needs to be carried out so that the assumption that microbial biopesticides are sustainable is fully justified.
