Daftar Isi:
- The research was conducted to determine the value of Economic Injury Level (EIL) and Economic Threshold (ET) at larvae of Lepidiota stigma instar 1, 2 and 3 in three different locations. To determine the loss of result per m2 data on the maximum harvest outcome and harvest outcome in the field per m2, amount of larvae population and plant per m2 in the field and weight proportion of the vanished root or to be eaten by a larva were needed. The proportion value of the outcome loss per m2 on the Walker Model which has been modified on biological control with Nematode Entomo Patogen (NEP) Steinernema spp., which was combined with light trap the highest is Tempel Sari i.e. larvae instar 1 (0.0108), instar 2 (0.0174), and instar 3 (0.0221) and the lowest is in Grenjeng i.e. larvae instar 1 (0.0048), instar 2 (0.0078), and instar 3 (0.0099). There is significant differences among the three instars where the consume greediness of instar 3 is higher than instar 1 and 2 so that the proportion value of the outcome loss per m2 of larvae instar 3 in the respective location is higher than the two other instars. Determination of EIL value based on Bode & Calvin Models with the highest EIL value is in Grenjeng, that are larvae instar 1 in amount of 15.50 with ET value 12.40
