The brown planthopper has evolved a highly adaptive oviposition strategy by exploiting caterpillar-induced plant volatiles that provide safe havens for its offspring.
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.
A lipid-binding protein mediates both attraction and hypersensitivity to a beetle sex pheromone in a specific type of nematode-insect relationship known as necromeny.
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.
