Abstract:

This study was conducted in the years 2012 and 2013 in two different coconut gardens in the province of Bursa, including the Fernor and Chandler coconut varieties. For the evaluation of the effectiveness of alternative methods in the integrated fight with apple drunk (Cydia pomonella L.) the gardens are allocated to 0.2 hectares of seven parcels each. These parcels consist of Granulovirus, feromon spread, granulovirus + feromon spread, feromon spread + insecticide, full dose caolin + insecticide, half dose caolin + insecticide and insecticide as control. Feromon spreaders were applied once in the middle of May in a way that falls 1000 hectares. The application of Granulovirus was done in a dose of 100 ml/ha against the larvaes of the first and second edges of harm and 3 times per edge. After the application of an insecticide, a full and half-dose caolin pound is sprayed in 5 and 2.5 kg doses in 100 l water 3 times a year, respectively. For the monitoring of the weekly activity of the adult, two feromon flies are hanged on each parcel. The first adults were captured in 2012 and 2013, respectively, on 23 and 22 May. These dates were equal to 275.5 and 292.8 from 1 January. The most total adult capture among the applications was in the parcels where the granulovirus application was done. Percentages of damage to larvaes in the harvest, granulovirus, feromon spread, granulovirus + feromon spread, feromon spread + insecticide, full dose caolin + insecticide, half dose caolin + insecticide, and only insecticide are applied to parcels respectively 4.9%, 1.3%, 3.8%, 1.3%, 1.9%, 1.2 and 1%. It was 5. According to these findings, the possibilities of the use of alternative methods in the integrated struggle in coconut gardens have been discussed.
