Özet
Bu çalışmada 2000-2002 yıllarında Aydın ilinde örtü altı çilek alanlarında zararlı kırmızıörümcekler (Tetranychus spp.) ile doğal düşmanlarının populasyon yoğunluklarının saptanması amaçlanmıştır. Aydın ilinde çilek üretiminin yoğun olarak yapıldığı Sultanhisar ilçesi ve civarındaki köylerde örneklemeler yapılmıştır. Yöreye çilek dikiminin yapıldığı ağustos ayından, tünellerin üstünün kapatıldığı şubat ayına kadar 15 günde bir, bu tarihten hasat sonu olan haziran ayına kadar haftada bir gün gidilmiştir. Çalışma sonucunda, kırmızıörümceklerin populasyon yoğunluğunun çileklerin üstünün kapatılmasından sonra genellikle şubat-mart aylarından itibaren artmaya başladığı, nisan-mayıs boyunca en yüksek seviyelere ulaştığı ve haziran başlarından itibaren populasyonun düştüğü saptanmıştır. Predator türlerin populasyonlannın, yörede zararlıya karşı yapılan yoğun kimyasal mücadele uygulamaları nedeniyle düşük olduğu belirlenmiştir.
The aim of this study was to determine the population densities of spider mites and their natural enemies on protected strawberries in Aydın province. This study was conducted in Sultanhisar and neighborhood areas, which have a big potential for strawberry production, during the growing seasons of 2000, 2001 and 2002. Surveys were carried out in every fifteen days from August, when seedlings were planted, to February, when tunnels were covered with polyethylene nylon. Additional surveys were also conducted once a week from February to June, when the harvest was completed. The results of study indicated that the population dynamics of spider mites began to increase generally in February- March, reached the maximum in April - May and started to decrease in early June. In this study, population levels of natural enemies were also determined. It was found that the population level was not high enough for controlling spider mite, this probably due to excessive use of chemicals against spider mites in commercial strawberry fields in this region.
