Chapter IV Prey Sensitization, Learning and Memory in Reduviids: Implications in Biological Control 4.1. Introduction Sensitization is an increasing response to a stimulus presented repeatedly while habituation denotes a failure of response to the stimulus (Staddon, 1988). The process of sensitization has enormous adaptive value. When a prey escapes from the clutches of a predator as a result of exhibiting a response, it gets sensitized.

As a rule, the gill area is greater in fast-moving crabs (Portunids) than in sluggish bottom dwellers; decreases progressively from wholly aquatic, to intertidal, to land species; and is greater in young crabs than in older crabs. Often the gills are enclosed in protective chambers, and ventilation is provided by specialized appendages that create the respiratory current. As in cephalopod mollusks, oxygen utilization is relatively high—up to 70 percent of the oxygen is extracted from the water…
