Abstract

 

Ants are social insects which widespread and play many important roles in an ecosystem. Myopopone castanea ants are predator for the pre-adult stage of pest Oryctes rhinoceros which is one of the important pests in oil palm plantations. At the oil palm plantations, M. castanea and pre-mature stadia from pests O. rhinoceros live on decaying palm oil stems. This study aimed to explore the existence of M. castanea ants in oil palm plantations and measure the parameter of abiotic environment in the ant nest in order to mass rearing of M. castanea ants. Study wascarried out in the laboratory to support the natural enemy augmentation program in biological control of O. rhinoceros pest.The exploration of ant nests took place in smallholder oil palm plantations in Tanah Merah sub-district, Binjai Selatan Subdistrict, Binjai city, North Sumatra Province. The results showed that the temperature range obtained at the ant nest was 28-31 C, the humidity was 68-75%, the pH range was 5.9-7, and the weathering rate (C / N ratio) was 33.93-92.34 %. A suitable abiotic environment will support life and mass rearing of M. castanea ant colonies.
