摘要

本研究旨在评估埃塞俄比亚中部住宅区和露天农田中的地下白蚁巢穴:农民对原因和影响的了解和看法。研究采用描述性研究设计,从埃塞俄比亚中部选定的地区收集原始数据。白蚁巢穴按当地称为 "Gox "的分区分组后,在每个 kebele 进行计数。白蚁巢穴计数共使用了 72 个 1 平方公里的抽样框。此外,还从每个区随机抽取了 190 位户主进行问卷调查。瓦拉博(Warabo)的白蚁巢穴数量较多(每 1000 平方米 7.251.71 个),而瓦伦苏(Warke Walensu Kebele)的白蚁巢穴数量较少(每 1000 平方米 2.250.50 个)。受白蚁危害最严重的作物是柚子(49.5%)和小麦(32.6%)。瓦拉博乡每户每年平均受损的土地公顷数和茶叶与小麦的公担数较高 (p = 0.000),而瓦莱苏乡最低。Warabo Kebele 地区因白蚁影响而造成的农作物年经济损失更大(每户的茶叶和小麦损失分别为 4722.23 ± 869.67 ETB 和 4396.43 ± 852.65 ETB)。农业生态、森林砍伐、放牧和作物种类是决定白蚁数量及其对农民生计影响的因素。开土堆和熏制是传统的管理方法,但没有得到政府的支持。因此,综合有效的白蚁虫害治理对研究地区的长期粮食安全至关重要。

Subterranean termite nests in residential and open crop fields in central Ethiopia: Knowledge and perception of farmers on causes and effects

This study aimed to assess subterranean termite nests in residential and open crop fields in Central Ethiopia: knowledge and perception of farmers on causes and effects. A descriptive research design was used for primary data collection from the selected district of central Ethiopia. Termite nests were counted from each kebele after clustered into local division called Gox. A total of 72 sampling frames with a 1 km2 were used for termite nests count. In addition, 190 household heads were selected at random from each kebele for questionnaires survey. Termite nests were abundant in Warabo (7.251.71 per 1000 m2), but scarce in Warke Walensu Kebele (2.250.50 per 1000 m2). Teff (49.5%) and wheat (32.6%) were the crops most severely affected by termites. The mean annual hectares of land and quintals of teff and wheat damaged per household were higher in Warabo Kebele (p = 0.000) and lowest in Warke Walensu Kebele. The annual economic loss from crops loss due to termite's effect was greater in Warabo Kebele (4722.23 ± 869.67 ETB and 4396.43 ± 852.65 ETB from teff and wheat per household, respectively). Agroecology, deforestation, grazing, and crop type were the factors that determine termite abundance and its impact on farmers' livelihoods. Mound opening and smoking were the traditional management methods used, but there was no government support. Therefore, integrated and effective termite pest management is critical for long-term food security in the study area.
