Abstract

We determined survival and degree-days required for development of immature citrus blackfly, Aleurocanthus woglumi Ashby, on 23 plant species. Only 7 plant species were theoretically capable of long-term support of a population of the insect, but only 5 Citrus spp., Clausena lansium (Laur.) Skeels (Wampi), Ardisia solanacea Roxb. (Ardesia), Dispyros dygyna Jacq. (black sapote) and Eugenia uniflora L. (Surinam-cherry) did so in screenroom tests. The number of degree-days required for development did not vary significantly among the plant species tested and there was no significant correlation between this and percent survival. Four plant species — Citrus spp., Mangifera indica L. (Mango), Schinus terebinthifolius Raddi (Brazilian-pepper) and Surinam-cherry — constituted 97% of all host plants surveyed in Broward County, Florida. Population numbers of the citrus blackfly are influenced mostly by Citrus spp., while non-citrus hosts are important as refuges and in aiding dispersal.
