This page provides all possible meanings and translations of the word ovipositor
egg-laying tubular structure at the end of the abdomen in many female insects and some fishes
A tubular protruding organ for laying eggs.
Origin: From ovum + positor.
The ovipositor is an organ used by some animals for oviposition, i.e., the laying of eggs. It consists of a maximum of three pairs of appendages formed to transmit the egg, to prepare a place for it, and to place it properly. In some of the insects the organ is used merely to attach the egg to some surface, but in many parasitic species it is a piercing organ as well. It is used by grasshoppers to force a burrow in the earth to receive the eggs and by cicadas to pierce the wood of twigs for a similar purpose. Both long-horned grasshoppers and sawflies cut the tissues of plants by means of the ovipositor. None of these examples is quite as remarkable as the wasp genus Megarhyssa, the females of which have a slender ovipositor several inches long that is used to drill into the wood of tree trunks . These species are parasitic in the larval stage on the larvae of horntail wasps, hence the egg must be deposited directly into the host's body as it is feeding. The sting of Hymenoptera is also an ovipositor, in this case highly modified and associated with poison glands that are used to paralyze prey. This would allow eggs to be laid without the host fighting back, and probably also to suppress the host's immune system so that it can't destroy the eggs or shake off the paralysis. However, in virtually all stinging hymenopterans, the ovipositor is no longer used for egg-laying.
