Sažetak
This study was conducted to investigate the influence of elevation and the cultivation system of Arabica coffee against the attack of the coffee berry borer (Hypothenemus hampei Ferrari, 1867) in Arabica coffee plantations in Central Aceh District, Aceh Province, Indonesia. We observed the attack level of H. hampei on Arabica coffee plants that were cultivated both organically and conventionally. Those were planted at three different altitudes, namely: 900- 1,100 m; 1,100-1,300 m and 1,300-1,500 m above sea level. The results showed that the attack level of coffee berry borer (CBB) on organic coffee plantations was lower than on conventional ones in general. The attack level of CBB on organic and conventional coffee plantations for 5 observations was between 16.9 - 26.1% and 23.4 - 33.6%, respectively. The results also showed that the attack level of CBB was influenced by the altitude of the coffee cultivation. At an altitude of 1,300-1,500 m, the attack level of CBB ranged from 11 to 17%, and this was much lower than at altitudes below 1,300 m. Meanwhile, at an altitude of 900-1,100 m and 1,100- 1,300 m, the attack level by this pest was around 27-40%. The results of this study indicated that both cultivation systems (organic and conventional) and altitudes of coffee plantation greatly influenced the attack level by CBB. Altitude is directly related to the temperature, while the cultivation systems are thought to have an effect on the level of presence and the role of natural enemies in suppressing CBB pest populations. Therefore, it is recommended to cultivate Arabica coffee organically, especially on the land at an altitude between 900-1300 m to reduce the attack level by CBB.
