We investigated the effects of heat stress on the responsiveness to vibrational cues,our measure of perceptual ability,in Myrmeleon bore antlion larvae(Neuroptera:Myrmeleontidae).We reared these trap-building predatory larvae under 2 heat stress regimes(mild,30°C,and harsh,36°C),and after they progressed from one instar stage to another,we tested their perceptual ability in common unchallenging *** hypothesized that exposure to the harsh heat stress regime would impose costs resulting in handicapped vibration *** found that the harsh heat stress regime generated more stressful conditions for the larvae,as evidenced by increased mortality and postponed molting,and the loss of body mass among larger ***,among the individuals who remained alive,those originating from the harsh heat stress regime were characterized by higher vibration *** results suggest 2 not mutually exclusive *** heat stress conditions can sieve out individuals characterized by poor perceptual ability or surviving individuals can attempt to hunt more efficiently to compensate for the physiological imbalance caused by heat *** of these mechanisms fit into the ongoing debate over how adaptation and plasticity contribute to shaping insect communities exposed to heat stress.
