Basic Ants olfactory system

By ughokay Feb 05, 2014 459 Words
400 distinct odorant receptors
Special proteins detecting different odors
Complex olfactory system:
Odorant receptors: identify different aromatic compounds and pheromones, and most dominant in ants Gustatory receptors: distinguish between different tastes and react to some pheromones Ionotropic glutamate receptors: narrowly tune to various poisonous and toxic compounds Two species will not have the same number of receptors, because of the difference of two species in terms of lifestyle Differences also are distinct in sex

Olfactory senses are present for chemical communication
Different ants mean different lifestyles
Distinct sense of smell determines themselves from other ants Ants use their antennae to detect odors. The antennae contain hairs that have nerve cells, at least a few thousand of these aforementioned cells. Special chemicals called pheromones differ in smell depending on the colony, therefore used as a way of communication, these chemicals are picked up with the antennae. Ants can recall the smells

Nutrition of ants usually come from greasy, starchy, and sweet foods Black ants are usually the ones in to human foods while red ants are in to natural foods such as leaves, other insects, or even birds and dead insects Honeydew, the sweet waste product of insects such as aphids, is another thing most ants are attracted to for eating Sweet scent is the strongest of the scents, and this makes them the easiest to be accessed Also, differing in the species, some will need more proteins, because of the factors including the difference of their physiology from one species to another, their diet in general, habitat, and as well as their environment Preferences will vary according to species, anatomy, sex, lifestyle, general diet, and habitat
