POPULASI ARTHROPODA HAMA DAN MUSUH ALAMINYA YANG TERPAPAR PESTISIDA KIMIAWI DAN PESTISIDA NABATI PADA PERTANAMAN PADI DI KECAMATAN PATAMPANUA,KABUPATEN PINRANG

Application of chemical pesticides in rice crops to control plant pests is still the first and foremost choice for farmers, especially in the districts of Pinrang. To deliver
environmentally friendly pesticides such as pesticide made from plant-based among these chemical pesticides, is an attempt to provide an alternative option for farmers for control action. This study aims to determine the presence and abundance of arthropod pests and their natural enemies when exposed to chemical pesticides and bio pesticides in rice cultivation in the district of Patampanua Pinrang. This study was carried out using 3 observations plot, consisted of plot applied with chemical pesticides, the plot applied with bio pesticide made from brotowali plant extracts and plot without application of pesticides (control). Each plot is repeated 3 times. Arthropod pests and their natural
enemies netted at each observation were collected then identified and tabulated. Types of pest collected were brown plant stem hopper, green leafhopper, fake white pests, white
back pests, armyworm, stem borers, walang rice pest. While the types of the natural enemies collected were spiders, dragonfly, parasitoids, Coccinellidae beetles, Carabidae
beetles. The highest number of arthropod pest populations netted was found in the plot applied with the bio pesticide ie. as much as 274 heads, then in the control plot (334
heads), while the least amount was in the plot applied with chemical pesticide which was
only 168 heads. The highest number of total population of arthropod natural enemies was found in the bio pesticide treatment plot as much as 110 heads, followed in the control
plot as much as 105 heads while the least number of arthropod natural enemies was found the chemical pesticide treatment plot which was only 84 heads. It can be concluded that the population of arthropod pests and their natural enemies exposed to pesticides tend to decrease / decreases while the population of arthropod pests and their natural enemies exposed to bio pesticides or without pesticides relatively constant / not decreased
