Bemisia tabaci, a polyphagous insect with over 900 host plants, is an effective vector of more than 100 plant viruses. Being highly fecund, B. tabaci has the potential to develop insecticide resistance rapidly as demonstrated by reports of use failures with MEAM1 and MED cryptic species (commonly known as biotypes B and Q, respectively). Insecticide resistance management is a key component of pest management practices. The research herein studied season-long rotational management programs on poinsettia and their impact on the ratio of MEAM1: MED cryptic species in the surviving treated populations.
