Aleurodicus dispersus RussellSuggested common name: Spiraling whitefly |
 |
Diagnosis: As given by Russell (1965:49) "Mature pupa with a copious amount of a white cottony secretion extending upward and outward from the dorsum; some fluffy, some waxy and in ribbons as long as, or longer than width of body; a white, glasslike waxy rod arising from each compound pore, 3-4 times longer than width of body; a band of whitish, translucent, striated wax extending from ventral submargin to leaf. Nearly flat dorsally; young pupae flat ventrally, but mature ones with ventral surface swollen and surrounded by a band of wax. Colorless or yellowish. Membranous. Nearly oval, 1-1.25 mm long and 0.75-0.90 wide."
Comments: The life history of this whitefly has not been determined, but apparently several generations are produced each year. In south Florida all stages of development may be found throughout the year (Weems 1971).
At this time, this whitefly is apparently not an economic pest of citrus in Florida. Distributed only in Broward, Miami-Dade, and Monroe counties.
In Florida it is reported on Citrus aurantifolia Swingle and Citrus limon Burm. Of the species that occur on citrus in Florida this species may be confused with Metaleurodicus cardini, Paraleyrodes minei and P. perseae.
