Ankara ilinde kavunlarda zararlı kavun sineği [Myiopardalis pardalina (Bigot,1891) (Diptera: Tephritidae)]'nin biyolojisi ve mücadelesi üzerinde araştırmalar
Özet
Melon fly [Myiopardalis pardalina (Bigot, 1891) (Diptera: Tephritidae)] is the most important pest of the melons. The larvae cause to damage as feeding in seed cavity. Also, the tissues damaged by larvae and the colour turn brown and spread occurring in melon scent, taste and aroma of melon is disrupted so. Besides this kind of damage, some fungal agents infecting the melons by the exit holes of the larvae cause to decay. So, the melons have bad aroma and taste and lost market value.Some data related to biological parameters of melon fly (Cucumis melo L.) (Cucurbitaceae : Violales) which causes to important damages in melon farming were obtained both under laboratory and natural conditions with this study. The studies on the larva, pupa, adult stages and generation number of the pest were done in Kazan (Ankara) district which is one of the most melon grown areas in 2009-2010. It was determined that melon fly gives two generations in Ankara conditions. The generation durations (From egg to adult) changed between 32 and 41 days. Adult life was determined for females and males 15-22 days and 10-16 days in nature, 8-14 days and 6-10 days in laboratory, respectively. Efficiency of the different traps as color, feed and pheromone was searched in field conditions, however, all traps have failed to attract the pest. Some studies on partly area spraying with toxic bait were done first time against melon fly in Turkey. Preference studies in terms of melon fly damage were carried out between Ipsala and Kırkağaç varieties which are commonly grown in Ankara province, and no differenciences were recorded between the varieties. In addition, as a result of the analysis, changes were determined in taste and aroma of fruits of the two varieties.
