BioControl, the official journal of the International Organization for Biological Control, presents original papers on basic and applied research in all aspects of biological control of invertebrate, vertebrate and weed pests, and plant diseases. Coverage includes biology and ecology of organisms for biological control, and aspects of use including biological controls for integrated pest management, such as plant resistance, pheromones and intercropping. Papers presenting only laboratory trials on non-target effects of pesticides on natural enemies are not considered but papers dealing with the corresponding effects on community dynamics of natural enemies are welcomed.
