This session will examine to what degree some perennially discussed theoretical notions of how classical biological control ought to be conducted have actually guided or improved the conduct of real projects in recent years. This topic is relevant because at bottom, biological control is about...

An overview of the main species of insects and mites harmful to flowering and ornamental plants in southern Italy is provided.
