摘要

本研究旨在确定稻田小蝽(Leptocorisa sp .)的侵染率和种群密度。本研究采用的方法是有目的抽样。结果表明:塔纳明区稻田虫害强度为13.78%;平均人口密度最高的是Waninggap Miraf 46.6人,Yasamulya和Isanombias村44.33人,Yabamaru村38.6人,Bersehati村38.3人,最低的是Ammunay村30人。而每次观察的平均种群数量是第二次观察或55只,有46.4只,其次是第一次观察或45只,有37.4只,最后一次观察或65只,有29.8只。稻谷虫最喜欢的品种类型为英帕利(19.75%),不喜欢的品种类型为潘达纳斯(19.75%)。关键词:发病率,种群密度,稻田臭虫,稻田

TINGKAT SERANGAN DAN PADAT POPULASI WALANG SANGIT (LEPTOCORISA ORATORIUS) DI DISTRIK TANAH MIRING KABUPATEN MERAUKE
This study aims to determine the attack rate and population density of the paddy bug (Leptocorisa sp). The method used in this research is purposive sampling. The results showed that the intensity of damage caused by paddy bugs in Tanah Miring District was 13.78%. The highest average population density was in Waninggap Miraf 46.6 individuals, Yasamulya and Isanombias villages 44.33, Yabamaru 38.6, Bersehati 38.3 and the lowest Ammunay 30. While the average population in each observation was the second observation or 55 DAP as many as 46.4 tails followed by observations 1 or 45 DAP as many as 37.4 and the last observation or 65 DAP at 29.8 individuals. The type of variety that was most favored by the paddy bug was impari 19.75% and the one that pandanus did not like. Keywords:   Attack rate, population density, paddy bug, paddy
