The efficiency of several types of traps and attracting compounds for capturing of mediterranean fruit fly, Ceratitis capitata (Dip.: Tephritidae) in two orchards of Nectarine and Tangerine

Mediterranean fruit fly, Ceratitis capitata Wied (Diptera: Tephritidae) is one of the most important and dangerous pests of fruit trees in different countries including Iran. This study was conducted with the aim of comparing the effectiveness of some attractants and traps in mass trapping of Mediterranean fruit flies in Mazandaran province, Sari city, in 2020. The experiment was conducted in the form of a randomized complete block design with 5 treatments in two orchards, Nectarine and Tangerine. The number of fruit fly insects caught in the trap separately by gender (male and female) and non-target insects was counted and recorded weekly from the time of installation of the traps until the end of the installation (from July to December). According to the results, in both orchards, trimedlure sexual attractants and feeding attractants were preferred in attracting male and female fruit flies, respectively. In total, both male and female sexes, the highest and lowest number of trapping belonged to trimedlure and sticky yellow card treatments, respectively. The effect of temperature on the Mediterranean fruit fly population in tangerine orchard was significant, so that the noticeable decrease in temperature in December caused a significant decrease in fly hunting in this month. Non-target insects were more attracted and captured by ceratrap and biolure food attractants. In general, Mcphil trap with trimedlure had the maximum captured of male flies. For capturing female flies, by reducing the number of ceratrap and biolure traps in order to attract less number of non-target insects, more traps can be allocating to ceratinex attractor in orchard.
