The flight dynamics of the olive fruit fly Batrocera (Cacus) oleae Rossi in Dubrovacko-neretvanska county

Maslinova muha Bactrocera (Dacus) oleae Rossi najopasniji je gospodarski štetnik masline. Njena rasprostranjenost i brojnost u maslinicima izravno utječu na kvalitetu i trženje maslinovog ulja. U godinama s visokom populacijom maslinine muhe berba mora započeti ranije, što znatno smanjuje randman ulja. Na području Dubrovačko-neretvanske županije posljednjih se godina intenzivno prati dinamika leta maslinove muhe. Let se prati mirisno-hranidbenim lovkama, tipa McPhail i žutim pločama tipa CTP 3 uz dodatak feromona, amonijskih soli i hidroliziranih bjelančevina. Rezultati praćenja pokazuju usku povezanost leta maslinove muhe s visinom dnevnih temperatura i relativnom vlagom zraka. Praćenjem dinamike leta utvrđena su «žarišta» maslinove muhe te veća rasprostranjenost u zonama samoniklih formi divlje maslineThe olive fruit fly Bactrocera (Cacus) oleae Rossi is the most common economically important pest in olive orchards. The number and spread of the fly in orchards are also of great importance for quality and marketing of olive oil. In seasons with high populations of the olive fruit fly the picking and processing should start earlier which decreases the quantity of oil. In Dubrovacko-neretvanska County the olive fruit fly dynamics was followed. McPhail traps were used and yellow sticky traps CTP 3 with feromon, amonium and carbohydrates. The results show that the flight of the olive fruit fly is highly dependent of temperature and relative humidity. Following the flight dynamics the centres with high density of the olive fruit fly were detected in zones with lots of wild olive trees
