摘　　要：橘小实蝇、瓜实蝇和南亚果实蝇是为害水果、蔬菜的世界性重要检疫害虫。目前,这3种实蝇已入侵到我国南方地区且在广东省为害严重。本文结合实蝇的发生为害特点及其对瓜果蔬菜造成的经济损失内容,构建了实蝇为害损失评估模型,并评估了上述3种实蝇在每年可能对广东省社会经济造成的损失。评估结果显示,实蝇对果蔬的为害率在5%~20%之间时,这3种实蝇对广东省社会经济造成的经济损失总值估计在33.67~129.87亿元之间,其中,直接经济损失约为23.32~110.78亿元,间接经济损失约为3.51~12.26亿元,防治费用约为6.84亿元。Bactrocera dorsalis, B. cucurbitae and B. tau are regarded as worldwide important quarantine insect pests of fruits and vegetables. At present, these three species of fruit flies have invaded southern China and are causing serious harm in Guangdong province. In this paper, an assessment model of economic loss caused by fruit flies was constructed on the bases of combining the occurrence and damage characteristics of fruit flies and the components of economic losses. This model was used to assess the annually economic losses caused bY the above three fruit flies in Guangdong province. The results show that under fruit flies infestation rates from 5% to 20%, the total value of economic loss was estimated to be from 3.367 billion Yuan to 12.987 billion Yuan, this included 2.332-11.078 billion Yuan of direct economic loss, 0.351-1.226 billion Yuan of indirect economic loss, and 0.684 billion Yuan of prevention and treatment costs.
