Fruit flies belonging to Tephritidae family are highly destructive agricultural pests, posing a significant threat to various fruits and vegetables grown in Bangladesh. A comprehensive year-round survey was conducted at Atomic Energy Research Establishment (AERE) campus located in the central region of Bangladesh. Three types of male lures (methyl eugenol, cue-lure and zingerone) were used to detect and assess the diversity of pest fruit fly species. A total of seventeen species of Tephritidae fruit flies were detected in this survey. The Bactrocera carambolae fruit fly has been discovered for the first time in our survey area, indicating spread of its range towards the north-west region from its previous detection sites (Chattogram and Sylhet Divisions) in Bangladesh. Among the detected pest species, we identified six abundant species: Bactrocera dorsalis, Zeugodacus cucurbitae, Zeugodacus tau, Bactrocera rubigina, Bactrocera zonata, and Dacus longicornis. The most abundant species was the polyphagous fruit pest B. dorsalis, comprising 76.83% of the total captured flies. The species Z. cucurbitae was the second most abundant, representing 13.82% of the total trapped flies. The fitted curve to survey data using Gaussian mixture model revealed the existence of overlapped subgroups in the temporal population distribution of B. dorsalis and Z. cucurbitae. In addition, our statistical analysis of the six abundant Tephritidae fruit fly species revealed correlation of population dynamics with several factors including temperature, rainfall, humidity, photoperiod, and fruiting time of host plant species in the selected area.
实蝇科果蝇是极具破坏力的农业害虫，对孟加拉国种植的各种水果和蔬菜构成重大威胁。在位于孟加拉国中部地区的原子能研究机构（AERE）园区进行了为期一年的全面调查。使用了三种类型的雄性诱捕剂（甲基丁香酚、诱蝇酮和姜酮）来检测和评估害虫果蝇物种的多样性。本次调查共检测到17种实蝇科果蝇。在我们的调查区域首次发现了杨桃果实蝇，这表明其分布范围从孟加拉国先前的检测地点（吉大港区和锡尔赫特专区）向西北地区扩展。在检测到的害虫物种中，我们确定了六种优势物种：桔小实蝇、瓜实蝇、南瓜实蝇、番石榴实蝇、桃实蝇和长角果实蝇。最优势的物种是多食性果实害虫桔小实蝇，占捕获果蝇总数的76.83%。瓜实蝇是第二优势物种，占诱捕果蝇总数的13.82%。使用高斯混合模型对调查数据拟合的曲线显示，桔小实蝇和瓜实蝇的时间种群分布中存在重叠亚组。此外，我们对六种优势实蝇科果蝇物种的统计分析表明，种群动态与所选区域的温度、降雨量、湿度、光周期和寄主植物物种的结果时间等几个因素相关。
