Abstrak :

Larvae Oryctes rhinoceros L. is a pradature insect that looks very different from the adult insects that are often found in the remnants of rotted organic matter for example in the stems of oil palm that have been obsolete. Food is a source of nutrients used by insects to live and breed, if it  is available with suitable quality and quantity the insect population will rise rapidly. The development of horn beetle larvae is also influenced by abiotic factors (environmental factors), like: temperature and humidity. This reseach aims to  find out the population density of horn beetle larvae on degraded timber of oil palm oil in Kenagarian Koto Baru, Luhak Nan Duo district,  west Pasaman regency. This research was conducted in June 2017. This research method is descriptive survey, determining the location of the research by using purposive sampling technique. Where the location of the collection is based on the vegetation where the horn beetle larvae are collected. Sampling of horn beetle larvae was done by direct collection of horn beetle larvae present at research location by hand (handsortir) and dodos palm kits (egrek sawit), sampling done in the morning. The results showed that the population density of horn beetle larvae on the weathered sticks was 2.9 head stem  as high as close to the threshold. Environmental factors at the site support the life of beetle horn larvae.
