Control program was implemented in three orchards of mixed apricot varieties. Ceranock traps were hung in each tree of two separate orchards. Delta and McPhail traps were used to monitor Medfly population density in each treated and control orchards. Results indicated that Medfly activity in apricot orchards started during the last week of April coincided with the beginning of maturity for fruits of early varieties. The total of trapped insects in monitoring traps after one week of Ceranock application were 0, 1 and 31 adults for the 1st, 2nd and the control orchards, respectively. Three weeks later and on, the number of trapped adults started to increase dramatically. At the end of apricot season and after 45 days of Ceranock trap application, the number of trapped insects in monitoring traps reached 110, 111 and 2,349 adults/week, respectively, for the 1st, 2nd and 3rd orchard. The use of Ceranock traps reduced Medfly population density by 86%-97%. The percentage of fruit injuries in early maturing varieties were 0.75%, 1% and 34% for the 1st, 2nd and control orchards, respectively. While, late varieties were 2% and 3% for 1st and 2nd orchards, and 69% for the control. The percentage of reduction in fruit damages reached to 95% and 97%, respectively in the 1st and 2nd orchard. The results of this study demonstrate clearly the efficacy of Ceranock bait station, ＂attract and kill＂ system as a control measure for Medfly in apricot orchards.展开更多

Control program was implemented in six citrus orchards of mixed citrus varieties： Orange, Citrus sinensis; Mandarin, C. reticulate; Lemon, C. lemon; and Bergamot, C. aurantium. Ceranock traps 240/ha were hanged in trees of two separate orchards in each location, with third orchard served as control. Delta and McPhail traps supplied with pheromone were used to monitor Medfly population density in treated and control orchards. Results indicated that Medfly activity and presence in citrus orchards started during the first week of October coincide with the beginning of fruits ripening. The result indicated that Medfly population density in Wasit orchards was more than that of Baghdad orchards. The total trapped insects after two weeks of Ceranock were 59, 94, 142 and 205, 277, 765 adults for the firsst, second and the control orchards in the two locations, respectively. The percentage of fruit injuries were increased dramatically when fruits mature and its color turn to yellowish reaching of 35%, 56%, 21% and 32% in mandarin and orange fruits in Baghdad and Wasit orchards, respectively, compared with 3%, 4%, 4% and 5% in treated orchards, respectively. Calculated percentage of fruit damage indicated that reduction in injuries were 97% in mandarin and 96% in orange at Baghdad orchards and were 95% and 96%, respectively, in Wasit orchards. The results of this study demonstrate clearly the efficacy of Ceranock bait station, ＂attract and kill＂ system as a control measure for Medfly in citrus orchards.展开更多
