Ecology and behaviour of the ladybird beetles (coccinellidae)

INDICE: 1 Phylogeny by I. Kovar (Czech Rep.).Phylogenetic relations of the subfamilies of Coccinellidae are rather complicated and are now a matter of intensive study. Most recent opinions are summarised. 2 Variability and Genetic Studies by M. E. N. Majerus classical programmes is summarised in the first section, along with a discussion of factors that appear to correlate with their efficacy in particular ecological contexts. Risks inherent to introductions ofpredatory coccinellids are also discussed against the backdrop of the particular example of Harmonia axyridis in North America which has emerged as an invasive species. The second section deals with approaches for practical augmentation of coccinellid populations in both open and closed systems. The third section summarises research on cultural approaches for the conservation of coccinellid populations in agricultural ecosystems. Methods suitable for evaluating the impact of coccinellid predation on prey populatios are reviewed in the fourth section. 12 Desirable Trends in Future Studies by H. F. van Emden & I. Hodek (UK & Czech Rep.).The chapter will be based on ideas arrived at by the authors of chapters 1-11.
