Abstract

The spatial distribution of Bactrocera fruit flies in the Goa region (west coast of India) was studied using several dispersion parameters between April 2006 and March 2008 in three ecological zones, viz. coastal, midland and upland. These zones are 10, 25 and 50 km to the east from the coastline of the Arabian Sea at an elevation of 15, 70 and 100 m above mean sea level, respectively. The dispersion parameters revealed that the population of all the fruit fly species attracted to methyl eugenol-baited traps, viz. Bactrocera dorsalis, Bactrocera caryeae, Bactrocera zonata, Bactrocera affinis and Bactrocera correcta, followed the negative binomial distribution pattern and was highly aggregated or clumped.
