Medfly - Ceratitis capitata W. (Tephritidae) is the pest of increasing economic importance in Croatia. Since the first appearance more than fifty years ago, this pest has been spread in almost the whole region of Dalmatia and in Istria. In Dalmatia it is area from Konavle to Šibenik neighbourhood including islands, where this pest causes important damages on fruits of numerous cultivated and wilde sorts. The most imperilled fruit sorts are: fig tree – Ficus carica, peach - Prunus persicae, plum – Prunus domestica, apricot – Prunus armeniaca, mandarine tree – Citrus reticulata and kaki – Dyopirus lotus. In Istria, although pest presence, the damages are of lower importance. Outbreak, fly duration and medfly capture ammount may be very different on particular areas through the years. Beside climatic conditions, it considerably depends on number of host plants on which this pest might be reproduced. Therefore, first outbreak takes place in the very south of Dalmatia already by the end of July, namely Župa dubrovačka, Dubrovnik seaside and area of Ston. In Split area medfly appears by the begining of September, but the flight may be continued even till the end of December. In the appearance, attack intensity and fly duration monitorring programme during four years, traps type Chromotrap-M with parapheromone trimedlure added and traps type Modified Liquidbaitor Trap with parapheromone ceralure and insecticide DDVP added were used. |
