SYSTEMS OF COMMUNICATION IN INSECTS (Using at least three examples, discuss insect communication systems)

Social insects, much(prenominal) as bees, termites and ants, live together in groups as large as hundreds of thousands of individuals. In a colony of much(prenominal) size, allocation and sharing of tasks such as foraging and land protection is essential to the efficient running of the population, therefore insects delight a variety of intercourse systems. This essay discusses air and substratum borne vibrational communication, as well as pheromone and tactile systems, and provides ex angstromles of the practice session of these systems by various insects. Vibration is a common cl atrial auricle of communication between insects. Those such as crickets, katydids, grasshoppers and cicadas use vibrations to ready an air-borne sound audible to the human ear (Cokl & type Aere; Virant-Doberlet 2004), withal in many insect species, mum vibrations argon produced (Cocroft & Rodriguez, 2005). This soundless vibrational communication takes attribute via a substrate or medium s uch as water or a plant; commonly altogether detectable by humans using sensitive enter equipment (Cokl & Virant-Doberlet 2004). In a 2001 article, Roces and Tautz state that in legion(predicate) ant species, actor ants produce vibrational signals audible to humans, unless the ants are ? deaf?, and therefore insensitive to this air-borne sound and or else are extremely responsive to the substrate-borne component of the signal. Cokl and Virant-Doberlet (2004) outline the chief(prenominal) methods by which substrate-borne signals are produced. Percussion is when an insect strikes various torso parts against a substrate, and tremulation is when it rocks and jerks its body without striking the substrate directly. consort to Cocroft and Rodriguez (2005), plant stems, leaves and root are the main substrates used to canalise vibrational signals, curiously by herbivorous insects as they usually live on plants. The typical range of plant-borne vibrational communication betwe en insects is from 30 centimetres to 2 metre! s (Keuper & Kuhne 1983, Henry & Wells 1990, Cokl &...
