Abstract

Oil palm (Elaeis guineensis Jacq) is one of important plantations in the Indonesia role economy. Oil palm can be attacked by various pests or diseases from the nursery. One of the important pests is Oryctes rhinoceros. Some control methods are manually, mechanically, chemically and biologically which are environmentally friendly. One of the biological controls of the Oryctes larvae is with Aspergillus sp. This research was conducted at STIPAP Medan in June - July 2017. Treatment of Aspergillus A0, A1, A2, A3, and A4 bioinsecticides, concentrations of 0, 10, 20, 30, and 40 g / l. This study aims to determine the speed of mortality of larvae and concentration of Aspergillus effective. From the results of this study it can be concluded that mortality of O. rhinoceros larvae seen on day 18 after application of Aspergillus sp at the treatment A4 with dose 40 gram Aspergillus sp and Aspergillus sp. effective for controlling the O. rhinoceros larvae with mortality average above 90%.

Abstract

This research aims to know the number of populations of e. kamerunicus in two different heights, to know the comparison population males and females of e. kamerunicus in every height. Based on the results of sampling populations of insect pollinators of e. kamerunicus Palm. Total population sample of e. kamerunicus on Garden Adolina i.e. 2680 tail and on the grounds of flood Birung Ulu i.e. 4548 tail. The sample population average insect e. kamerunicus females i.e. 107 tail on the garden Adolina and 187 tail on the grounds of flood Birung Ulu, and insect populations of e. kamerunicus males i.e. 27 tail on Garden Adolina and 40 tail on the grounds of flood Birung Ulu. The higher the altitude of the place, the higher the average total precipitation per year, and the higher the population of e. kamerunicus
