A devastating tropical and subtropical pest that's already considered one of the world's top invasive species just got a bit more troublesome. The silverleaf whitefly (Bemisia tabaci) threatens a wide range of crops. Of the more than 20 known biotypes of this species, two of the most devastating are the B and Q biotypes. The Q biotype, newly arrived in the U.S., is less susceptible to many pesticide types.
