The two volumes are divided into three parts:
• The Soft Scale Insects presents a comprehensive account of the morphology, systematics, phylogeny, biology, physiology, ecology and techniques for their scientific study.
• The Natural Enemies covers the pathogens, predators and parasitoids.
• Damage and Control opens with an account of the major soft scale pests to agricultural crops in the world, and concludes with a series of eighteen sections on the coccid pests to the most important crops in the world.
The extremely broad coverage will make this book of value to extension officers, to agricultural, horticultural and forestry organisations interested in pest control, to quarantine officers and to research personnel working with soft scales.
