Abstract

<div data-canvas-width="788.5133333333328">Different types of rice pests, have been reported. The explosions and a potential pests are Rice Stem Borer (Tryporiza</div><div data-canvas-width="802.6483333333334">sp.), Brown Planthoppers (Nilaparvata lugens), Green Leafhoppers (Nephotettix virescens), and Rats (Rattus sp.), wich</div><div data-canvas-width="802.7016666666667">an obstacle in creating stability of rice production in Bone. In rice ecosystem, natural enemies of arthropod predators</div><div data-canvas-width="802.703333333333">are most instrumental in suppressing the pest population. Fluctuation in population density of natural enemies, affecting</div><div data-canvas-width="802.6466666666668">pests presence. Efforts to suppress pest proportions through IPM, is a strategy of lowering the level of pests and damage</div><div data-canvas-width="802.6933333333333">to rice crops. This study aims to identify and measure the relationship strength between pests and natural enemies</div><div data-canvas-width="802.6733333333332">populations in some rice varieties after IPM, using correlation and regression analysis. Observations conducted in Bone,</div><div data-canvas-width="802.6600000000001">from May to August 2012, with 2 observed variables, pests and natural enemies populations in Inpari 6, Inpari 10, Inpari</div><div data-canvas-width="802.6633333333332">16, Ciherang, Cigelis, and Mekongga. Data analysis were performed using correlation and regression analysis. The</div><div data-canvas-width="802.6833333333332">results showed a high degree of correlation between pest and natural enemies (predators) populalions, characterized by</div><div data-canvas-width="802.7066666666666">a positive correlation coefficient (0.957) and significant at the level of 0.01, where each increase in the intensity of pest</div><div data-canvas-width="564.7166666666665">populations, will be followed by increase in the number of natural enemies captured.</div>
