Abstract

Peanut ( Arachis hypogaea L.) is one of the food plants that is a protein source for Indonesians and has quite a high economic value. As well as having fat and protein content, can be found in peanut plants. In Indonesia, peanuts have been used as the main source of protein and vegetable fat. Uret ( Lepidiota stigma F), an insect of the order Coleoptera which causes damage to peanut plants, is one of the pests. Which has the potential to cause more than 50% root damage to peanut plants. This study aims to determine how the entomopathogens Metarhizium anisopliae, Beauveria bassiana, and Verticillium lecanii affect the level of urethral pest attacks. This study used a randomized block design (RBD) which consisted of 5 treatment levels with 5 replications. Based on the results of the study, Metarhizium anisopliae with a concentration of 7 grams/liter of water was able to withstand the attack power of urethra ( Lepidiota stigma F.) by 47.47% and was equivalent to artificial zinc poison with the active ingredient Carbofuran.
