This study was conducted to identify the distribution of Tephritidae fruit flies in Kuching until Sarikei division in Sarawak by relate the distribution of fruit flies to the environmental variables such as habitat type, disturbance effect, seasonal effect, and rainfall distribution. A total of 118 occasions and 13 species were recorded between year 2003 and 2011. The data collection was transformed into responding variables and predictive variables and analysed using the R-project software. All of the variables were analysed by using Generalised Linear Model (GLM). The Akaike’s Information Criteria (AIC) value showed that all of predictive variables effect distribution of fruit flies. Futher analyses had been done for six species of Genus Bactrocera which are B. papayae, B. dorsalis, B. umbrosa, B. cucurbitae, B. carambolae and B. tau. Result showed seasonal effect and rainfall distribution affected distribution of B. umbrosa with AIC value (579.609), B. cucurbitae (766.405) and B. tau (255.891). Besides that, B. carambolae and B. dorsalis showed lowest AIC value in disturbance effect with value B. carambolae (344.174) and B. dorsalis (570.158). Meanwhile, habitat type, disturbance effect, seasonal effect and rainfall distribution were affected distribution B. papayae (1210.676). The result from this study hopefully can aid in pest management especially in Southern part of Sarawak.
