This study between 2009-2010 years in the four olive gardens in the Adana, Hatay, Mersin and Osmaniye provinces of the Eastern Mediterranean region, Palpita unionalis (Hübnan). (Lepidoptera, Pyralidae) is performed in order to determine the volatility of the adult and larva populations. In these gardens, the damage rate of P. unionalis in olive fruits has also been determined. Adults of P. unionalis were followed by white-colored funnel-type traps containing [(E)-11-Hexadecenal and (E)-11-Hexadecenyl acetate)] with equally attractive feromon capsules. The larvaes were monitored by counting 100 evacuations from each garden. In these gardens P. unionalis adults are captured in a very low number of feromon hole, while larva and eggs have been determined in a high number and continued throughout the year. Population tracking in all of the gardens; P. unionalis larva has reached the highest number in the 5th, 7th and 11th months. It has been found that P. unionalis forms 4-6 hills in the Eastern Mediterranean region and all its periods are found together in the olives throughout the year. P. unionalis has been shown to be influenced by the development of the larva population as well as by climate factors (heat and moisture). Although P. unionalis causes its main damage to the fresh drainage and leaves of olive oil, it has been found that the larva of the second edge is also fed in the olive fruits and causes product loss of 0.3-2.8%. The damage to the larva was determined in the interval of 1-1.5 months, from the medium green positive period of the olive fruits to the falling period.
