near the posterior ventral part of the head. The common name “whitefly” was given
because the wings and bodies of adults are covered with a fine, powdery or flour-like
white wax (Fig. 3B). For this reason, early workers thought they were minute moths.
There are approximately 1,557 species in 158 genera that are distributed worldwide.
Whiteflies occur ona varietyof host plants, encompassing more than362species in97
plantfamilies(OuvrardandMartin2015).
