Florida armored scale insects.
This publication is a revision of a section on diaspidids in an earlier work on the scale insects of Florida by G. B. Merrill that was published in 1965. The number of species has increased from 120 to 134; many but not all are of economic importance in the state. The primary objective has been to prepare a non-technical publication for use by plant or plant quarantine specialists, agricultural extension workers, fruit growers, nurserymen dealing in ornamental plants, and homeowners. For each diaspidid species, notes are given on the morphology of the scale of the adult females, the food-plants infested, common names, distribution in Florida and neighbouring land areas, and other information on habits and injuriousness. Maps showing distribution in the counties of Florida are provided for every species, most of which are illustrated by means of photographs. The scale insects are also listed alphabetically with the plants they attack, and the food-plants are similarly listed with the scale insects found on them. Recommendations on chemical control included in the earlier publication have been omitted from this revision.
