What is an ovipositor in insects?
What is an ovipositor in insects?
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.
Is an ovipositor a stinger?
The stinger is a modified egg-laying apparatus, called an ovipositor, which is attached to poison glands. Many other hymenopterans have a piercing ovipositor, but do not sting humans. Sawflies and most parasitic wasps have ovipositors that are used only to lay eggs.
Which structures of insects are part of the ovipositor?
The hymenopteran ovipositor is derived from abdominal appendages and comprises three independently movable parts, called valves, that together form the egg canal. The dorsal valve is a fused structure, but the ventral ones are separate.
What is the function of ovipositor for female insects?
The ovipositor is a tube-like organ used by some animals, especially insects, for the laying of eggs.
Do male wasps have ovipositor?
Only female bees and wasps can sting. Males do not have the egg-laying ovipositor that is modified into a stinger on female insects. Unlike bees, these female wasps have the ability to sting a target multiple times because their stinger does not fall off after use.
What is the function of the ovipositor in a grasshopper?
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.
What type of mouthparts do grasshoppers have?
Grasshoppers. The grasshopper has mandibulate mouthparts that are directed downward for biting and chewing the leaves of a host plant. Its labrum is a broad flap that serves as a front lip. Mandibles operate from side to side.
What is the respiratory system of the grasshopper called?
tracheae
Insects, and some other invertebrates, exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae. Tracheae open to the outside through small holes called spiracles. In the grasshopper, the first and third segments of the thorax have a spiracle on each side.
How do female roaches get pregnant?
After mating, females produce an egg capsule that is approximately one-fourth of an inch long. This capsule contains 40 eggs, give or take a few. Unlike the female American cockroach, German cockroaches carry the capsule until about 24 hours before the eggs are ready to hatch.
Are male wasps aggressive?
During fieldwork in Brazil’s Atlantic forest, known as Mata Atlântica, Eric Lucas and Jeremy Field from the University of Sussex, observed that sometimes male wasps do react aggressively against intruders in their nest.
What is the function of the ovipositor?
What is the function of the ovipositor in the grasshopper?
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.
Is a grasshopper an omnivore?
Grasshoppers are herbivores, not omnivores. Since they are herbivores, this means that they are primary consumers in terms of a food chain….
What are the body parts of a grasshopper?
Parts of an Insect (Grasshopper) Head: The anterior part of an insect body with eyes, antennae, and mouthparts. Thorax: The body section after the head, with the legs and wings attached. There are three sections of the thorax: the prothorax, the mesothorax, and the metathorax.
