Searching and handling times
The Odonata H. ephippiger nymphs showed clear differences
in searching and handling times towards the three-prey sizes
(Table 1). Data obtained show that, the nymph required more
time in searching for the small and medium snails as compared
to the large snails. The maximum searching time (21.40 ± 1.90)
min was obtained by the predator nymph towards small snail
when predator nymphs were satiated, whereas the minimum
searching time (6.00 ± 0.71) min was obtained with the large
snail when the predator nymphs were starved. Significant differences
(P < 0.05) were obtained in the handling time of the
predator nymph towards the three sizes of snails. Handling time
of the starved predators towards the snails was (6.80 ± 0.86),(7.80 ± 1.20) or (12.00 ± 0.71) min for the small, medium and
large snails, respectively. A similar relationship was also obtained
with the handling time of the satiated predator.
Comparing searching time or handling time of starved and
satiated predators, significant difference (P < 0.05) were obtained
in both searching and handling times of the predators
towards the three different prey snails
