Abstract

Pest control with usage entomopathogenic fungi opportunity was developing as biological control agent for example: Cordyceps militaris Fries local. The experiment was conducted in Plant Pest Laboratory from August until September 2015. The objectives study was to find the better prapagation medium for control rhinoceros beetles larvae (grubs). The experiment used completely randomized design (CRD) with three treatment and nine replication. The treatment tasted were maize, rice sifting and red seeds. The result showed that all propagation medium can be used to as propagation medium entomopathogenic fungi local Cordyceps militaris Fries and effective to control Oryctes rhinoceros L. grubs in laboratorium.

Abstract

Research aims to obtain dose of spiked pepper fruit flour (Piper aduncum L.) better of  imago S. oryzae on the rice. Research conducted at the laboratory of plant pests, Faculty of Agriculture, University of Riau from May to June 2015. The Research was conducted experimentally by using completely randomized design (CRD), which consists of 5 treatments, where each treatments was repeated 4 times to obtain 20 units experiment. The treatment used in the research is (0 g/ 100 g, 2 g/ 100 g, 4 g/ 100 g, 6 g/ 100 g, 8 g/ 100 g of rice). Data obtained analyzed statistically using analysis of variance followed by least significant difference (LSD) at 5%. Dose applications of spiked pepper fruit flour at doses 6 g/ 100 g rice better of  imago S. oryzae with lethal time50 24,5 hour and mortality by 97,5% inhibit the growth of the population, shrinkage weight of rice, and lethal dose95 by 4,5%.
