Biological control offers farmers a safe, effective and environmentally friendly way of safeguarding their crops against damage caused by insects and other pests. Using the natural enemies of pests as control agents, biological control is an increasingly attractive alternative to chemical pesticides, the overuse of which, especially in concentrated cocktails, can have serious detrimental effects on human health and on the environment. Chemical pesticides can also be costly, as they must be applied with increasing frequency as the pests develop resistance to the chemicals. This volume contains authoritative papers from leading experts on the biological control of thrips and whitefly, two major pests in the Caribbean region.
