Abstract: Biological control has been principal choice in integrated pest management since 1960s. Lots of achievements on biological control technologies were developed and applied. The proportion of biocontrol in IPM increased each year and started to dominate. Grasshoppers and locusts are important pests in the world, they caused lots of losses and are a threat for agricultural and husbandry area. In the study and application on biological control of grasshoppers and locusts, the parasites of grasshoppers and plant pesticides were applied more at early period as agents controlling grasshoppers and locusts, but at present, the entomopathogenies, such as fungus, microsporidia, nematodes, virus and bacteria and so on, these biological agents played more important role in the practices. These problems such as less variety and formulation, high cost and unstable effects partly restricted the development and application of grasshopper biocontrol, but the advantage of bio-agents including environmental friendliness, ecological safety and unease to form resistance for pest have made the industry become a necessary trend in global pesticide industry, which have promoted the development of grasshopper biocontrol to low cost, diversified variety and formulation for the future, for example Paranosema that could transmitted vertically, semiochemicals of locusts, fungi agents, natural enemies of grasshoppers and locusts and ecological managements, they are applied coordinately, and then keep complimentary effects and sustainable control for grasshoppers and locusts.

Key words: grasshopper, IPM, biocontrol, bio-agents
