The ovipositor appendages of acridid insects (grasshoppers and locusts) consist of two pairs of shovel-shaped valves that are used to dig a deep chamber in the ground for egg burial, to manipulate the eggs, and to assist in capping the egg-pod with froth. read more
In insects an ovipositor consists of a maximum of three pairs of appendages. The details and morphology of the ovipositor vary, but typically its form is adapted to functions such as transmitting the egg, preparing a place for it, and placing it properly. read more
Rhythmical ovipositor movements are produced by the severed abdomen of sexually mature female grasshoppers. By comparing this activity to the activity underlying the natural behaviour, it was determined that the isolated abdomen produced the digging portion of the oviposition motor programme. read more
An ovipositor is a tube in insects and most fish, whereupon the female deposits eggs. In grasshoppers the ovipositor consists of two shovel shaped valves used to dig an egg chamber in the ground and assists in capping the eggs in a frothy moist mist to protect from desiccation. read more
