Fire ants use track pheromones to mark the path from the colony to feeding sites. Trace pheromones are mainly known in insects living in colonies, which mark their paths with low-volatile substances such as higher molecular weight hydrocarbons. Ants in particular often mark the path from a food source to the nest in this way. [77]
Trail pheromones are semiochemicals secreted from the body of an individual to affect the behavior of another individual receiving it. Trail pheromones often serve as a multi purpose chemical secretion that leads members of its own species towards a food source, while representing a territorial mark in the form of an allomone to organisms ...
Pheromones can be used instead of insecticides in orchards. Pest insects are attracted by sex pheromones, allowing farmers to evaluate pest levels, and if need be to provide sufficient pheromone to disrupt mating. Chemical communication in insects is social signalling between insects of the same or different species, using chemicals.
Pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual. [5] There are alarm pheromones, food trail pheromones, sex pheromones, and many others that affect behavior or physiology. [6] Their use among insects has been particularly well documented. In addition ...
Ants use pheromones for more than just making trails. A crushed ant emits an alarm pheromone that sends nearby ants into an attack frenzy and attracts more ants from farther away. Several ant species even use "propaganda pheromones" to confuse enemy ants and make them fight among themselves. [91]
Aphid honeydew can provide an abundant food source for ants (aphids in the genus Tuberolachnus can secrete more honeydew droplets per hour than their body weight) and for some ants, aphids may be their only source of food. In these circumstances, ants may supplement their honeydew intake by preying on the aphids once the aphid populations have ...
Colonies of real army ants always have only one queen, while some other ant species can have several queens. The queen is dichthadiigyne (a blind ant with large gaster) but may sometimes possess vestigial eyes. [5] The queens of army ants are unique in that they do not have wings, have an enlarged gaster size and an extended cylindrical abdomen ...
Pheromones are released by many social insects to lead the other members of the society to the food source. For example, ants leave a pheromone trail on the ground that can be followed by other ants to lead them to the food source. Alarm calls Alarm calls communicate the threat of a predator.
