Tropical countries face considerable economic losses due to mosquito-borne diseases which can be effectively combatted using plant-based mosquito repellents. Therefore, using a questionnaire survey, we selected the 25 top-ranked common but underutilized aromatic plants with mosquito repellent ability in Sri Lanka to investigate the rural sector's willingness to cultivate and supply them. , , , , , and were the common species thus identified. The willingness to cultivate and supply aromatic plants with mosquito repellent ability varied between 88% and 60%. The Chi-squared test indicated a significant association between gender and willingness to cultivate and supply these plants. Men had a higher willingness (82%). Persons formally educated up to elementary school level had the highest willingness (85%). The willingness from households with many non-income-generating members was 100%. The random forest model developed in this study identifies farmers' willingness to cultivate and supply aromatic plants with mosquito repellent properties. It was trained using an upsampling strategy. Our findings aid in understanding the scenarios involved with introducing, cultivating, and supplying aromatic plants.
热带国家因蚊媒疾病面临巨大经济损失，而使用植物性驱蚊剂可有效对抗这些疾病。因此，我们通过问卷调查，在斯里兰卡挑选了25种排名靠前但未得到充分利用的具有驱蚊能力的常见芳香植物，以调查农村地区种植和供应这些植物的意愿。由此确定的常见物种有 、 、 、 、 、 。种植和供应具有驱蚊能力的芳香植物的意愿在88%至60%之间。卡方检验表明性别与种植和供应这些植物的意愿之间存在显著关联。男性的意愿更高（82%）。接受过小学教育的人意愿最高（85%）。有许多无收入成员的家庭意愿为100%。本研究开发的随机森林模型可识别农民种植和供应具有驱蚊特性的芳香植物的意愿。它采用了上采样策略进行训练。我们的研究结果有助于了解引入、种植和供应芳香植物所涉及的情况。
