Mealybugs of California, with taxonomy, biology, and control of North American species (Homoptera: Coccoidea: Pseudococcidae).
AbstractThis excellently illustrated work has introductory sections on the economic importance, control, ecology and bionomics of mealybugs, with special reference to California, the cytology of mealybugs in general, methods of collecting and preserving specimens, the morphology and classification of the group and a review of the North American genera (including a key to them), each with its own bibliography. The bulk of the book is devoted to the taxonomy of the Californian species (of which 193 are recognised, over 30 being described as new species), including descriptions, keys, information on distribution in California and elsewhere in North America (with maps) and a table showing the distribution by counties in California.
In an addendum, it is stated that heavy infestations of Pseudococcus comstocki (Kuw.) were found on fruitless mulberry (Morus alba) at Porterville, Tulare County.
This mealybug was first observed in North America in 1917 on mulberry and apple in New York and subsequently spread to other eastern States. Plans for its eradication from California are currently being considered.
