Abstract

The study was conducted in Ciptamarga Village, JayakertaSubdistrict, Karawang District, West Java - Indonesia within one cropping season in 2018. The study was started in September 2018 and terminated in December in the same year. The study site was a large irrigated rice farm belong to farmers with size around 40 hectares. The farmers plantedInpari 32 and Inpari 42 rice varieties twice a year. Rodent has been recognized as the most destructive pest in this area which accompanied by brown plant hopper, stem borer and virus as the minor pests and disease of the rice crop. The objective of this study was to control the rice field rats as the main pest contributing some losses to the local farmers. The second purpose was to determine the effectiveness of our ecologically based rat control technology which implemented by integrating several components. At the beginning of cropping season we performed sanitation, mass hunting and fumigation on the main habitats which continued by setting a TBS (Trap Barrier System) and LTBS (Linear Trap Barrier System) in different habitats. The TBS functions as a lure crop by planting those rice crop three weeks earlier than surrounding areas, as the rice field rats prefer to the generative stage. The LTBS was assembled to protect the next staggering crop by trapping rats regularly on their main habitats within a whole season. LTBS was also effective to catch the rats which move back and forthto the rice field and village after harvesting. We have set four units of TBS and four units of LTBS during the cropping season which incorporated with 48 bubu traps. We also protected seed nurseries by erected plastic fence combined with 16 bubu traps along the fence. We recorded the number of rat captured from those activities along the cropping season.

印度尼西亚西爪哇省卡拉旺县鼠类生态综合管理的实施及其保护农民灌溉水稻作物的有效性
该研究于2018年的一个种植季在印度尼西亚西爪哇省卡拉旺区JayakertaSubdistrict的Ciptamarga村进行。该研究于2018年9月开始,并于同年12月结束。研究地点是一个面积约40公顷的大型灌溉水稻农场。农民们每年种植两次dinpari 32和Inpari 42水稻品种。鼠类是该地区公认的最具破坏性的害虫,其次是褐飞虱、螟虫和病毒,是水稻的次要病虫害。本研究的目的是控制稻田老鼠作为给当地农民造成一定损失的主要害虫。第二个目的是确定我们的基于生态的老鼠控制技术的有效性,该技术通过整合几个组成部分来实施。在种植季节开始时,我们对主要生境进行了卫生、大规模狩猎和熏蒸,并在不同生境设置了TBS(陷阱屏障系统)和LTBS(线性陷阱屏障系统)。由于稻田鼠类更喜欢繁殖阶段,TBS比周围地区提前三周种植这些水稻作物,起到引诱作物的作用。LTBS是为了保护下一个惊人的收成,在整个季节内定期在老鼠的主要栖息地捕捉老鼠。对采后在稻田和村庄来回移动的老鼠,LTBS也能有效捕获。我们在种植季设置了4个TBS单元和4个LTBS单元,其中包括48个陷阱。我们还设置了塑料围栏,并沿围栏设置了16个陷阱,以保护苗圃。我们记录了在种植季节从这些活动中捕获的老鼠数量。这些防鼠技术均取得了较好的效果,在一个种植季节内捕获了大量鼠类,共计2306只。这些措施对当地农民产生了积极的影响,减少了鼠类数量,提高了产量。短句来源强化灭鼠后,平均产量由1.9吨/公顷提高到6.4吨/公顷。对实施灭鼠技术前后的产量数据进行了比较分析。结果表明,这些值之间存在显著差异。从这一点上看,农民们似乎急于在下一个种植季节采用这项技术。该研究于2018年的一个种植季在印度尼西亚西爪哇省卡拉旺区JayakertaSubdistrict的Ciptamarga村进行。该研究于2018年9月开始,并于同年12月结束。研究地点是一个面积约40公顷的大型灌溉水稻农场。农民们每年种植两次dinpari 32和Inpari 42水稻品种。鼠类是该地区公认的最具破坏性的害虫,其次是褐飞虱、螟虫和病毒,是水稻的次要病虫害。本研究的目的是控制稻田老鼠作为给当地农民造成一定损失的主要害虫。第二个目的是确定我们的基于生态的老鼠控制技术的有效性,该技术通过整合几个组成部分来实施。在种植季节开始时,我们对主要栖息地进行了卫生、大规模狩猎和熏蒸,并通过设置TBS(陷阱屏障系统)继续进行。
