Notes: Most of the 12 papers contained in this publication on the ecology of the pseudococcid Phenacoccus manihoti on cassava in Africa (with special reference to conditions in the Congo) have already appeared or have been submitted for publication elsewhere. They are arranged as 5 chapters entitled: The mealybug and its biotic potential; Variations in abundance and periodic factors; Relations between the pest and its host-plant (consisting of an apparently unpublished paper by G. Fabres & B. le Ru on the influence of cassava on the biology of the coccinellid); Variations in abundance and factors that affect them (consisting of papers on parasitic and predacious natural enemies of the mealybug); and Entomopathogens (especially fungi).
