Insects and spidermites do significant damage to vegetable crops in all tropical regions around the world. Today, agro-ecological crop protection methods such as biological control are recommended. This work, a veritable handbook, features 22 references describing the major groups of arthropods: pests and natural enemies (predators and parasitoids). The bio-ecology of these groups and the means at our disposal to control pests are detailed along with many photographs.

Based on a specific experience relating to an artisanal fishery study in Senegal, the author shows that the role of statistics must sometimes go beyond that for which it was initially intended. When findings clash with reality at the conclusion of a research programme, it could be that there is no clear relationship with the initial question(s) posed. That is when statisticians must get involved.
This book, written by a scientist who specialises in cocoa and is a chocolate lover himself, takes us on a journey around the world to discover the culture of cocoa and its processing. Step by step along the way we meet small growers, merchants, traders and chocolate makers. Nutritionists and law makers reveal secrets and guidelines. We view the process through the eyes of a chemist as we explore the molecules of the aroma and follow them during the fermentation and roasting of the beans. Eventually we get to taste the chocolate and distinguish the different locations where beans are grown. Filled with the author's personal experiences, this beautiful book introduces us to the great history of chocolate, the saga of a delicacy known as the "food of the gods".
