An analysis of western flower thrips Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) in lemons: Its abundance, distribution and damagernstatus

Ekrem Atakan, Murat Ölçülü, Serkan Pehlivan, Okan Özgür

Abundance, distribution of thrips species occurring on citrus as well as damage level of western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is studied in Yenice, Tarsus, Turkey during 2013-2014. As a result, 10 different thrips species were investigated. Thrips fauna was dominated by the F. occidentalis having 98.25% of total adult of the thrips population. The coefficient of determination (r2) of Taylor indices ranged from 0.62 and 0.92 for larvae and 0.43 and 0.92 for adult F. occidentalis. The values coefficient b of Taylor were always less than 1 (two-tailed t test, P < 0.0001), indicating a regular population distribution. Majority of larval or adult F. occidentalis was detected in flowers. The highest thrips densities with mean of 6 or 7 individuals (larvae+adult) per flower in nontreated plots did not cause any damage to flowering parts or developing fruits. Spraying of citrus lemon against thrips is not warranted.
