While digging during oviposition, female grasshoppers stand on the ground as their abdomen tip burrows beneath them. The digging movements are produced by the heavily muscled ovipositor valves located on abdominal segments 8 and 9 (A8 and A9).
Is ovipositor an organ of reproduction?
organs for sperm transfer or ovipository (egg-laying) organs. Gonads produce the gametes and hormones essential for reproduction.
Where Is The ovipositor found on a female grasshopper?
A notable example is the ovipositor of a grasshopper. Extending beyond the tip of the abdomen, the ovipositor is comprised of two pairs of shovel-shaped structures. One pair is located dorsally (on top) and one pair ventrally (on the bottom), These are called 'ovipositor valves'.
Which structure of insect are part of the ovipositor?

How does a ovipositor work?
The ovipositor is a tubular structure that is used for laying eggs. The ovipositor is attached to the abdomen of insects and the eggs pass down the tube. ... Insects that possess ovipositors include many of the solitary wasps, crickets and many species of fly.
What is the function of ovipositor for female insects?

Do males have an ovipositor?
Though both males and females have two cerci, only females have an ovipositor. It may look like a third cerci, or appear to be a different length. Female crickets use this organ to lay eggs into the soil.
Do butterflies have an ovipositor?
Butterflies of both sexes have two pairs of extraocular photoreceptors on the genitalia. Here we demonstrate in female Papilio xuthus that a pair of the genital photoreceptors, P1s, is crucial for oviposition. ... As soon as the ovipositor touches the leaf surface, the female deposits an egg and glues it on to the leaf.
Do cockroaches have ovipositor?
Some fossil ancestors of modern roaches has long ovipositors, but whether they deposited individual eggs is not definitely known. In the introduction, attention is invited to several reports of human disease organisms transmitted by cockroaches.
Do bugs have sperm?
Most insects reproduce oviparously, i.e. by laying eggs. The eggs are produced by the female in a pair of ovaries. Sperm, produced by the male in one testis or more commonly two, is transmitted to the female during mating by means of external genitalia. The sperm is stored within the female in one or more spermathecae.
How do bugs mate?
For most insects, mating requires direct contact between a male and a female. Generally speaking, much like humans, the male of the insect species uses his sex organ to deposit sperm into the female's genital tract spurring on internal fertilization.
