For many years researchers have espoused the view that nature's helpers (natural enemies, beneficials, predators and parasitoids) are a free resource that has not been well utilised in our pest management approaches. We have over-relied on insecticides, many of which were highly disruptive to non-target species. The past few years have seen a remarkable transition where integrated pest management (IPM) has been embraced and successfully applied by many in the industry. Nature's helpers have finally gained some well-deserved recognition. This recent transition is not unlike that which occurred when resistance to pyrethroids first occurred. To place any reliance on endosulfan was almost unthinkable. Some perceived endosulfan as not much better than 'lemonade' (Murray and Cull 1984), yet almost 20 years on, endosulfan still has a very important role in pest management. Such are the changing fortunes in pest management.
