    Abstract

    Larvae of Lepidiota stigma is the most impediment pest in increasing soybean production in dry lands area. Intensive application of insecticides is ineffective and also costly. Research was conducted on the mixture of compost and chopped tobacco stem to determine the larval behavior. Larvae were placed in mixing media with tobaccos concentration of 1.25, 2.5, 5.0 and 0%. Position of larvae were recorded daily (24h) for six days. Analysis of variance and DMRT were done on data. Effects of tobaccos mixture occurred since the first day of observation. Larvae significantly moved fastest in longest distance at concentration of 5.0%. Effect of tobaccos active substances began to decline at the fourth and fifth day at concentration of 1.25 and 2.50% respectively, as the increase of movement distance was declining. Meanwhile, at concentration of 5.0%, effect of tobaccos active substance has not decrease yet up to the sixth day of observation. Protection's coverage areal of larval attacks were in radius of 4 cm and 16 cm on applications of 1.25 and 2.5% tobacco's mixture respectively, while application of 5.0% at a radius over than 36 cm
