Evaluating the effect of certain lures in two different forms and traps on attraction of the mediterranean fruit fly , ceratitis capitata (weid.).

Field tests were conducted to evaluate the efficiency of three trap types  {McPhail , Jackson and Makkar & El-Abbassi ( a new trap ) }  and  three attractant materials ( Agrinal , Buminal and Conserve) against the Mediterranean fruit fly, Ceratitis capitata ( Weid.).The attractant materials were used in two forms ( liquid form and in a paste form) . Trials were carried out in two different locations at Qualubia Governorate within the period from  October 29^th till  December 25^th 2013 . First location (  Kafr Shokr district  ) was cultivated with a mixture of some  varieties  of citrus trees , while the second location ( El-Kanater district ) was planted with navel orange. Data revealed that McPhail trap was superior among all tested traps based on potency  and  attraction of med flies ( specially females) . On the other hand , the attractant material Agrinal was superior among other tested materials on basis of potency and attraction of adult flies. Moreover, the best combination between trap type and attractant material in attracting and capturing med fly adults was recorded when McPhail traps were loaded with Agrinal . Finally, results showed that number of attracted non-target organisms for all tested attractant materials were much higher  in traps loaded with the  attractant in a  Iiquid form when compared with their corresponding in the paste form. Also , a bad smell ,rot and fungi growth were observed and recorded in McPhail traps loaded with the tested materials within few days post loading  . Usage of the attractant material in a form of paste has some advantages based on : easy to use, no attraction of non-target organisims and avoidance of contamination with fungi and emission of bad smell . However more investigation should be conducted to increase its performance.
