Resumo

A study was conducted to study the effect of altitude on the presence and effectiveness of entomopathogenic fungi in suppressing the development of the coffee berry borer (Hypethenemus hampei Ferr.) in Arabica coffee plantations in Aceh Tengah District, Aceh Province, Indonesia. We found that only the fungus of the genus Beuveria infects CBB pests in the coffee plantations. We also found that the infection rate of this fungus against CBB pests in coffee fields located at an altitude of 900-1,100 m was higher than in coffee fields located at an altitude above 1,100 m. At first observation showed that the attack rate of entomopathogenic fungi against CBB at an altitude of 900-1,100 m; 1,100-1,300 and 1,300-1,500 m were 6%, 3% and 1%, respectively. In the second observation, the attack rate at an altitude of 900-1,100 m, 1,100-1,300 m and 1,300-1,500 m, were 8%, 2% and 1%, respectively. This indicates that the higher the temperature around the coffee plantation, the higher the infection rate (attack) of the Beuveria fungus on CBB. The correlation analysis also showed that an increase in CBB attack on coffee berries was generally followed by an increase in entomopathogenic fungi attack. This indicates that the Beuveria sp fungus has played a role in suppressing and balancing the development of CBB pests in Arabica coffee plantations in Aceh Tengah District.
