Insect Natural Enemies: Practical Approaches to Their Study and Evaluation.

Abstract

Part 1 Foraging behaviour, J.J.M. van Alphen and M.A. Jervis: behaviour of insect parasitoids and predators methodology the treatment of parasitoids prior to their use in experiments recording and statistical analysis of behavioural data host/prey finding and selection behaviour deciding what clutch size to lay host-feeding behaviour host discrimination sex allocation functional responses switching behaviour patch time allocation patch defence behaviour distribution of parasitoids over a host population measuring encounter rates life history characteristics and searching behaviour foraging behaviour and taxonomy parasitoid behaviour and community ecology. Part 2 The life cycle, M.A. Jervis and M.J.W. Copeland: anatomical studies female reproductive system male reproductive system sex ratio locating eggs in hosts fecundity adult longevity growth and development of immatures survival of immatures intrinsic rate of natural increase. Part 3 Mating behaviour, H. van den Assem: making records general methodology equipment used in observing mating behaviour the early stages of mating behaviour stimulus production some quantitative aspects of mating behaviour female receptivity and its consequences aspects of mating sensu stricto mating success comparative studies of mating behaviour. Part 4 Populations and communities, W. Powell and .M.P. Walton: field sampling techniques determining trophic relationships genetic variability in field populations of natural enemies. Part 5 Population dynamics, N.A.C. Kidd and M.A. Jervis: demonstrating and quantifying predation and parasitism the role of natural enemies in insect population dynamics selection criteria in biological control. Part 6 Phytophagy, M.A. Jervis and N.A.C. Kidd: what plant materials do natural enemies feed upon, and from what sources? do natural enemies show specificity in the plant food sources they exploit? interpreting patterns of resource utilization insect preferences and foraging energetics natural enemies as pollinators.
