B. geminata nymph-an aquatic predator consumed highest number of the larvae ofAnopheles (24.20) followed by Aedes (16.89) and Culex (13.19) larvae. The prey numbers consumed by each dragonfly species were significantly different. The mean biomass consumption of B. geminata nymph on Aedes (32.79 mg), Anopheles (31.87 mg) and Culex (30.64 mg) larvae was almost equal. Irrespective of prey species, there was no significant difference in the consumption of total biomass. B. geminata nymph had maximum consumption rate (%) against Anopheles (80.67%), followed by Aedes (56.30%) and Culex (43.97%) larvae. Predatory impact of B. geminata nymph on the smaller size mosquito larvae was more (8.96) as compared to large size mosquito larvae. The clearance rate (CR) of B. geminata nymph on various species of mosquito larvae ranged between 1.29 and 1.59 which remained constant throughout 10 days period. B. geminata is important biocontrol agent of mosquitoes.

A total of 42 species belonging to 27 genera, under seven families and two suborders were recorded. A total of 16 species of Zygoptera (damselflies) and 26 species of Anisoptera (dragonflies) were recorded. Anand District was surveyed intensively and as a result a maximum of 35 species was recorded (Dragonfly 22 and Damselfly 13), whereas less intensively surveyed districts, i.e., Panchmahal (17) and Dahod (16) had comparatively low species richness. Twenty-two species are being reported for the first time from central Gujarat, raising the total list of odonates to 48. Six species reported in an earlier survey were not encountered during this study. Seven species namely, Copera marginipes, Pseudagrion microcephalum, Anaciaeschna jaspidea, Anax immaculifrons, Epophthalmia vittata, Brachydiplax sobrina, Tramea basilaris burmeisteri are being recorded for the first time from Gujarat State. Hence, now the checklist of the odonates of Gujarat is raised to 65 species.

Total 29 species belonging to two suborders, five families and 22 genera were recorded. Total 9 species of Zygoptera (damselflies) and 19 species of Anisoptera (dragonflies) were recorded. Twelve species were common, 13 were uncommon and 4 were rare.
