Among the insect olfactory receptors the odorant receptors (ORs) evolved in parallel to the
onset of insect flight. A special property of this receptor type is the capability to adjust …

The sense of smell enables insects to recognize and discriminate a broad range of volatile
chemicals in their environment originating from prey, host plants and conspecifics. These …

Since the emergence of the first living cells, survival has hinged on the ability to detect and
localize chemicals in the environment. Modern animal species ranging from insects to …

Insects have a remarkable capacity to sense a wide range of volatile chemicals in their
environment with high sensitivity and specificity. Chemical cues originating from various …

Insect olfactory receptors (ORs) detect chemicals, shape neuronal physiology, and regulate
behavior. Although ORs have been categorized as “generalists” and “specialists” based on …

In animals, the sense of smell is often used as a powerful way to attract potential mates, to
find food and to explore the environment. Different animals evolved different systems to …

Odorants provide insects with crucial information about their environment and trigger various
insect behaviors. A remarkably sensitive and selective sense of smell allows the animals to …

Insects rely on their olfactory systems to detect relevant chemical cues in the environment
and drive several important behaviors such as finding food and mates. A wide variety of …

The majority of insect olfactory receptors belong to two distinct protein families, the
ionotropic receptors (IRs), which are related to the ionotropic glutamate receptor family, and …

The insect olfactory system is a suitable model for exploring molecular function of odorant
receptors, axonal projection of olfactory receptor neurons onto secondary neurons, and the …
