Evaluation of Various Attractants and the Trap Height to Install them for Trapping Zaprionus indianus (Diptera: Drosophilidae) in a Mixed-Fruit Orchard in Shiraz (Fars province)

The African fig fly has been reported from Iran in 2009. The use of chemical insecticides has several environmental limits therefor the efficiency of some attractants has been evaluated for trapping of this insect in Iran. A field experiment was conducted in Completely Randomized Factorial Design with four replicates to determine the best attractant for trapping and the best height for installing traps on trees in Shiraz city, in 2009. The first factor was attractants including: Solution of pomegranate sauce 3 % (3% pomegranate sauce%water), Solution of hydrolyzed plant protein 3% (3% hydrolyzed plant protein %water) and Ceratrap. The second factor was height for installing traps on trees including: 75, 150 and 225cm. Results revealed significant differences among the attractants and height for installing traps in all weeks except 13th week and also the interaction effect between them. The evaluation showed that the best attractant for capture was solution of pomegranate sauce 3 % with significant difference from the others. Evolution about the best height for installing traps showed that 150 cm height for installing traps was better than the others. So traps with solution of pomegranate sauce 3 % that installs on trees at a height of 150 cm could have an important role to decrease the population of this pest and it is an approach in order to non-chemical control.
