Evaluation of efficacy of various traps and attractants to control of Med fly, Ceratitis capitata (Dip: Tephritidae) in Shiraz city.

Mediterranean fruit fly (med fly), Ceratitis capitata (Diptera: Tephritidae), which considered as an important quarantine pest in Fars province, was recorded on mandarin fruit in Shiraz in January 2007. To determine the best combination of trapand attractant for trapping of med fly, a field experiment was conducted in a randomized complete block design (RCBD) with 6 treatments in 3 replicates in a mixed frui and a pomegranate orchard (2 hectares) in 2009 – 2010 respectively. Treatments were included: 1-Jackson trap baited with trimedlure, 2- Mcphail trap baited with trimedlure, 3- Tephri trap baited with biolure, 4- Tephri trap baited with Cera trap liquid, 5- Plastict bottle baited with Cera trap liquid and 6- Yellow sticky card.Traps were checked weekly and the number of captured flies and non -target insects were recorded. Mean number of total captured flies per treatment per day (FTD) and non- target insects per treatment per day (NTID) were calculated. Data were transformed to homogenize their variance before analysis of variance (ANOVA) followed by Duncan's Multiple Range Test (DMRT). Results revealed significant differences among the treatments at probability level of 0.01 (df =5, F=129.58; P0.0001) in both orchards. In mixed fruit orchard, FTD were 3.16, 3.08, 0.6, 0.24,0.07, and zero respectively but NITD were 0.05, 0.02, 3.83, 7.42, 11.06 and 1.86respectively. Also in pomegranate orchard, FTD were 0.77, 1.9, 0.58, 0.2, 0.13, and zero respectively but NITD were 0.01, 0.02 , 2.46 , 4.19 , 6.79 , and 0.74 respectively. Population peaks of med fly were observed between 11-25th. October. Minettia sp. (Diptera: Lauxaniidae) was the dominant species among the non target insects captured by some treatments. Mean Percentages of total captured adult males in treatments 1-5 were 96, 95, 21.05, 29.7 and 23.75 respectively. In conclusion,treatments 1 and 2 are recommended as the best for mass trapping of the med fly in the fruit orchards in Shiraz.
