Most of the published studies of Delphastus pusillus biology and behavior on Bemisia spp. actually refer to D. catalinae. Similarly, Delphastus species in commercial insectary cultures are probably D. catalinae and not D. pusillus. (Hoelmer & Pickett 2003)
Explanation of Names
pusillus (L). "very little, very small, petty, insignificant"
Range
Distribution of D. pusillus is now restricted to the eastern half of the U.S. (Hoelmer & Pickett 2003)
Season
May-Aug (BG data)
Food
attacks all species and stages of whiteflies, but prefers eggs and nymphs (species profile by R.A. Cloyd)
Bemisia tabaci, Bemisia argentifolii
Remarks
Commercially available to control whiteflies, but see Hoelmer & Pickett (2003)
