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.
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 ...
"Scout" ants are the first ones out of the mound every morning. They seek food, and mark their path as they return to the mound to alert the worker ants. The worker ants follow the scent trail and collect the food. Other worker ants clean, extend, and generally tend to the mound, the queen, and the brood. All the ants in the colonies are ...
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]
Ants want to shelter from the pounding raindrops, but their underground colonies can get flooded. They also can be swept away in the downpour, since ants, like most insects, can float.
Wild wedge-capped capuchin monkeys (Cebus olivaceus) self-anoint with millipedes (Orthoporus dorsovittatus).Chemical analysis revealed these millipedes secrete two benzoquinones, compounds known to be potently repellent to insects [6] and the secretions are thought to provide protection against insects, particularly mosquitoes (and the bot flies they transmit) during the rainy season.
