Abstract

Batı çiçek thripsi, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) çileğin önemli bir zararlısı olarak bilinmektedir. F. occidentalis Türkiye’de çileklerde ana thrips türü olarak bilinmesine karşın, örtü altında ilaçlı ve ilaçsız parsellerinde bitkiye olan zararına ilişkin karşılaştırmalı veriler bulunmamaktadır. 2011-2012 yıllarında, yeşil ve kırmızı meyveler ile karşılaştırıldığında, önemli sayıda F. occidentalis larvaları ve erginleri çiçeklerde bulunmuştur (P<0.05). Ekonomik zarar eşiği (EZE) değerine (10 thrips /çiçek) göre çiçeklerin %60’ı 10 veya daha fazla thrips ile bulaşık olmuştur. Ayrıca, kırmızı meyvelerin yaklaşık %6’sının 1 veya daha fazla sayıda thripsle bulaşık olduğu da saptanmıştır. Onbeş ergin thrips /çiçek ve ayrıca yeşil veya kırmızı meyvelerde 0.40 veya 0.60 ergin thrips /meyve ile en yüksek thrips yoğunlukları zarara neden olmamıştır. 2011 ve 2012 yıllarında ilaçlı ve ilaçsız parseller arasında verim yönünden önemli farklılıklar bulunmamıştır. Mevcut ekonomik zarar eşiğinin F. occidentalis için oldukça düşük olduğu, çiçek başına 15 F. occidentalis bireyinin bile çiçeklerde görünen zarara neden olmadığı kaydedilmiştir. Elde edilen sonuçlara dayanarak, F. occidentalis’in EZE’nin yeniden değerlendirilmesi önerilmektedir.

Pest status of western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), in tunnel-grown strawberry

Abstract

The western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is often recognized as a serious pest of strawberries worldwide. Although F. occidentalis is known as the dominant species among thrips infesting strawberry plants, limited information is available about comparable data of treated and untreated plots of tunnel-grown strawberry in Turkey. In this study, significantly more larvae and adults of F. occidentalis were collected from the flowers, when compared with red or green fruits during the year 2011-2012 (P<0.05). Nearly 60% of flowers were infested with 10 or more adults, which is the current economic threshold level (ETL; 10 thrips per flower) in this crop. Furthermore, about 6% of red fruits were found to be infested with one or more adults and larval thrips. However, it was observed that population density i.e. 0.4-0.6 and 15 adults per green or red fruit and flowers, respectively, did not cause any damage to the flowers and fruiting parts. No significant difference was observed in the yields of treated and untreated strawberry plots during 2011-2012. It was concluded that population density i.e. 15 F. occidentalis individuals per flower may not cause visible damage. Furthermore, economic threshold level for F. occidentalis (ETL; 10 thrips per flower), appears to be too low. It is suggested that the ETL of F. occidentalis in strawberry needs to be re-evaluated in Turkey.
