A moth can detect plant volatiles using an odorant receptor expressing in its ovipositor, and this odorant receptor has a much higher expression level in the ovipositor than antennae.

The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.

Hundreds of fossil remains shed new light on the evolution of grasshoppers, gryllids, and katydids and their ecological role 300 million years ago.

The activation of Drosophila Or7a receptors guides aggregation and egg-laying behaviors towards both green leaf volatiles and a male-specific food-odor-induced pheromone.

The gustatory receptor PxylGr34 is tuned to the steroid plant hormone brassinolide and mediates the deterrent effects of brassinolide on feeding and ovipositing behaviors in Plutella xylostella.

Plants detect the presence of phospholipids in eggs from a herbivorous insect and trigger innate immunity.

Instead of repelling, Desmodium, a hallmark of pest suppressive sustainable intercropping, acts as a mechanical and developmental barrier to larvae, thereby truncating population development.

The universal bacteria cell wall component peptidoglycan impacts the egg-laying behavior of infected Drosophila females by directly modulating the activity of few brain octopaminergic neurons.

Finch embryos are laid at an earlier stage than other avian embryos and contain cells with similar properties to pluripotent embryonic stem cells from mice.
