Özet

Bemisia tabaci is a significant insect pest that causes extensive agricultural damage. The MEAM1 (Middle

East-Asia Minor) and MED (Mediterranean) genetic groups of B. tabaci are the most prevalent cryptic species. This

study investigated the potential for resistance development in the MED and MEAM1 genetic groups of B. tabaci against

cyantraniliprole. Additionally, multiple-resistance development within each genetic group for pyriproxyfen, spirotetramat,

and acetamiprid insecticides was determined. To assess the susceptibility of the first-larval stage of B. tabaci,

we employed a systemic uptake method with cyantraniliprole. Additionally, we utilized a leaf-dipping method to apply

acetamiprid, spirotetramat, and pyriproxyfen to second-instar larvae, adults, and eggs of B. tabaci, respectively, to determine

the LC50 values for each insecticide. Each genetic group was subjected to six selections using cyantraniliprole.

After six rounds of selection, a 1.8-fold resistance was observed in the B. tabaci MEAM1 population, whereas the

MED population exhibited a 1.4-fold resistance. While B. tabaci MED and MEAM1 genetic groups exhibited very low

resistance to cyantraniliprole, it's important to note that no multiple-resistance was observed with pyriproxyfen, spirotetramat,

or acetamiprid in either group. These findings provide valuable insights for future monitoring and developing

insecticide resistance management strategies for B. tabaci.
