Predatory Arthropods For Brown Planthopper Species (Nilaparvata Lugens Stal): A Comparisonal Study Based On Agroforestric

Abstract

This study describes the potential of agroforestry ecosystems in supporting the diversity of predatory arthropods in rice fields during the planting interval, problems are often found in the planting interval process, so the cause of the error must be found. Methodology: Two locations of rice fields around agroforestry with different types of agroforestry were selected, namely rice fields adjacent to simple agroforestry and complex agroforestry in Gunungcupu Village, Sindangkasih District, Ciamis Regency, West Java. Arthropod species data were obtained using a mask and suctioning was carried out with an aspirator. There are 40 sample plots at each location. Plots were placed systematically in rice fields adjacent to agroforestry with a distance between plots of 10 m and a distance between plots of 10 m. Observations were made since the beginning of the first planting period, September 20, 2018, continued during the planting interval and the end of the planting interval in the last week of the second planting period on June 14, 2019. Results: Based on the results of the analysis, it was found that the even distribution of predatory arthropod species in the rice fields was not affected by the planting period. The planting interval also did not affect the diversity and even distribution of insect predatory arthropod species. This condition indicates that agroforestry areas have the potential to support the diversity of arthropod species in paddy fields
