Chemoecology of Insect Eggs and Egg Deposition

The fascinating research field of chemoecology of insects mainly considers larval and adult states, while insect eggs have been somewhat neglected up to now. However, as immobile stages the eggs are highly vulnerable and need to cope with numerous problems such as predation, parasitisation, pathogen infection and plant and host defences. How do they face these dangers? Insects have been shown to endow their eggs with various naturally occurring chemicals that deter or poison enemies. These chemicals may be produced either by the insects themselves or their endosymbionts, or they may be obtained from host only on the protective power of the eggs themselves, but also on the site where they have been laid. The ovipositing female is known to be informed by numerous infochemicals about the suitability of sites for egg deposition and development. This is the first book focusing on the chemoecology of insect eggs and egg deposition. The much-needed synthesis of a broad array of facets of this topic includes molecular, chemical, physiological, morphological, ecological and evolutionary aspects. A wide range of different insects is addressed: herbivorous and carnivorous insects, social insects, and those of medical and veterinary importance. The knowledge compiled in this book may promote future studies on evolutionary aspects of insect reproductive behaviour as well as on controlling insect pests by targeting the egg stage. Thus, it may provide important information for researchers interested in both fundamental and applied research, as well as also for readers who are just fascinated by the multiple facets of the chemoecology of insects.
