The Preference of Thrips tabaci for Allium cepa, Allium fistulosum, and Allium roylei

Thrips tabaci Lind. (Thysanoptera: Thripidae) is a key pest of onions worldwide. It causes both direct and indirect damage to onion crops, resulting in high yield losses. Today, the Integrated System Production Plant Protection requires growers use onion- thrips-resistant cultivars. has become apparent that improvement existing cultivars may not be sufficient, so it necessary search for desirable plant traits related disease resistance among wild For this purpose, we conducted bioassays on possible preference T. three different Allium cepa L., namely, Alibaba, Bila, Tęcza, one cultivar Kroll Welsh onion, fistulosum species roylei Stearn. The settling oviposition rate female thrips were evaluated using choice no-choice laboratory tests, respectively. During bioassay, leaf sections A. species, significantly higher number females was recorded compared cv. Tęcza each observation period. Significantly more settled Alibaba Bila. Regarding results obtained cepa, fewer found Bila Tęcza. Opposite observed combination cvs. Tęcza–Alibaba, where insects leaves Alibaba. Statistically significant differences between cultivars/species hatched larvae tested onion. lowest from eggs laid roylei, as except
