英文摘要：

Biological control of agricultural and urban pests has gained importance in recent years due to increased pressure to reduce the use of chemical insecticides and their residues in the environment and food. Insect viruses are valuable natural control agents and they have been genetically modified to improve their insecticidal activity. There are two major strategies at present, in a broad sense, for improving the timing of killing action of these agents, i. e. interference with host physiology and introduction of an insect-specific toxin. Recombinant insect viruses are efficacious in the laboratory, greenhouse and field trials. Hopefully, the negative influence of social perception of genetically modified organisms on biotechnological research will gradually decrease and recombinant insect viruses will be introduced as an important biological factor in the near future.
