The growing use of pesticides for fishing is a current practice of concern for biodiversity in Eastern Africa. There is little information available, however, on the extent and effect of this practice on conspicuous indicator groups like dragonflies. Odon., especially during the larval stage, are particularly vulnerable to pesticides. This survey found significant differences in both dragonfly abundance and diversity in bays of Lake Victoria that had been fished using pesticides. Only 1-2 dragonfly spp. can be found in areas routinely pesticide-fished in contrast with > 20 spp. in protected areas. This survey highlights the detrimental effect of pesticide fishing on invertebrates.
