Abstract:
Oryctes rhinoceros L is one of the major pest of oil palm plantation which can cause damage to 69%. Attacks sheath of leaf that has not been opening and the growing point, this cause disruption of plant growth. Conventional control usually used by the farmer is by using chemical insecticides which can result negative impacts to humans and environment. The use of aggregation pheromons is an alternative control to reduce the population of Oryctes rhinoceros in the field which save for humans and environment. The purpose of this reseach is to obtain the effective height of pheromone traps for Oryctes rhinoceros beetle, and conducted in the oil palm plantation owned by the farmers in four villages located in the district of Tambang.
Using a Randomizeed Block Design ( RBD) with three treatments and four replications. The treatments are trap heights, 2 meters, 3 meters and 4 meters.
The parameters measured were the first time Oryctes rhinoceros L traped, the number of Orycte rhinoceros males trapped, the number of Oryctes rhinoceros females was trapped, the number of Oryctes rhinoceros males and females was trapped.
The results indicate that the addition of the height of traps do not influence the treatmants. 4 meters trap can trap more, that is 14.5 Oryctes rhinoceros beetle during 6 weeks.
