How do cockroaches lay their eggs and what do cockroach eggs look like

Cockroach eggs are laid in the tail end of the female cockroach after the male and female cockroaches mate, and the eggs are laid in it. A female worm can lay more than 10 eggs and more than 90 egg sheaths.

Brief introduction. The dorsal plate of the abdomen of male and female worms is called the supraanal plate, and there is one pair of multi-segmented tail barbels on both sides of its base. The ventral plate of the female and the ventral plate of the male are called the inferior genital plate.

The male has one pair of needles (ventral spines) on both sides of the end of the lower genital plate, which is an important feature to distinguish between sexually important adults.

Females lay eggs inside special glial sacs, forming egg sheaths (egg pods). The egg sheath is produced by the secretion of the female, which is smooth, hard and waterproof, which protects the development of the embryo within it.

The egg sheath of cockroaches is excreted by females and is usually found on the surface of objects, such as the corners of cabinets, wooden boxes and tables, or in piles of clutter. The egg sheath of cockroaches comes in different shapes and colors depending on the species.

After mating, the female usually chooses a relatively hidden place, first lays a depression on the surface of the object, lays the egg sheath in it, and then covers the egg sheath with sticky saliva mixed with bitten wood chips or pieces of paper, this way is to protect the eggs, because the cockroach egg sheath contains enough nutrients to meet the needs of embryonic development.

In addition, some species of females will lay their egg sheaths and then drag them on the ventral end until the nymphs hatch out of the egg sheath. In this way, the nymph hatches in the egg sheath and receives the water and nutrients it needs from the mother, which is more beneficial for the nymph's growth.

That's how cockroaches lay their eggs.

Cockroach eggs. It is after mating that the female cockroach tail grows egg-containing organs.

Cockroaches are flattened, black-brown in color, and usually medium in size. The antennae are filamentous and the compound eyes are well developed. The forewings are leathery, the hindwings are membranous, and the fore and rear wings are basically the same size, covering the dorsal surface of the abdomen.

Cockroaches are one of the oldest insects on the planet, having lived in the same era as ancient creatures such as dinosaurs, trilobites, and dunkles. It was even more than 100 million years before the first dinosaur on land was born.

According to fossil evidence, primitive cockroaches appeared on Earth about 400 million years ago in the Silurian period. The fossils of cockroaches that we have found or those found in coal and amber have become more and more resilient and have flourished to this day, widely distributed in all corners of the world.

The larvae have no eggs, just like people, after growing up and fertilizing and pregnant, there are eggs in the stomach, and you can use the Jiebing cockroach bait (**with anti-counterfeiting code) to exterminate!

Cockroach eggs are narrow, elongated, milky-white, and translucent. A female worm can lay more than 10 eggs and more than 90 egg sheaths. In an egg sheath, 10 can be hatched, and more than 50 small cockroaches can be hatched, which is related to the cockroach species, and their fecundity is very strong.

Freshly molted larvae and newly fledged adults are also white, gradually darkening in color and finally turning brown or black. So at the beginning we saw that the newly hatched cockroaches were white, and many people didn't know what they were when they saw these little things, in fact, they were the larvae of the cockroaches.

Precautions for cockroaches

Cockroaches are not parasites, they cannot survive in the human body or animals, even if they do not eat into it, they will be digested and absorbed by the body, so cockroach eggs will not parasitize in the human body.

However, it should be noted that cockroaches can carry parasites and pathogens, and if some of the cockroaches they eat carry these things, they may multiply in the body and cause damage to health.

After the male and female cockroaches mate, the tail end of the female cockroach grows a pod-shaped thing called an egg sheath, and the eggs are laid in it. A female worm can lay more than 10 eggs and more than 90 egg sheaths. In one egg sheath, as few as 10 cockroaches can hatch, and as many as 50 small cockroaches can be hatched.

To kill cockroaches indoors, we must first do a good job of sanitation and remove cockroach habitat conditions, and extensively carry out plugging holes and wiping cracks and "eight checks" activities to remove cockroach habitat egg sheaths and cockroach traces.

Cockroaches, commonly known as cockroaches, are common medical insects that belong to the "order Cockroaches" (scientific name), belonging to the phylum Arthropods, Insecta, and Blataria, commonly known as cockroaches.

Cockroaches have flat, black-brown bodies, and are usually medium in size. The head is small and can move. The antennae are filamentous and the compound eyes are well developed. wings flat, forewings elytra, hindwings membranacean, anterior and posterior wings basically equal in size, covering the dorsal surface of the abdomen; Some species are wingless. Not good at flying, able to walk quickly.

Cockroaches like dark, damp places with food, as well as some hidden locations, and cockroaches also prefer to frequent, such as in the corners and crevices of drawers and wardrobes, where cockroaches are often found.

The biggest fear that cockroaches crawl into the closet is that cockroaches will lay eggs inside. In fact, there is this possibility, if cockroaches crawl into the closet, they may also lay eggs inside, grow small cockroaches, and even they will hide in clothing and then lay eggs on clothing.

The larval stage of cockroaches.

The larvae that have just hatched from the egg sheath are gathered around the egg sheath, which is white, and then the color gradually darkens and spreads out, and the larvae are similar in shape to adults, but the body is small, wingless, and the sexual organs are immature. The larvae develop slowly. It must undergo multiple molts to grow gradually, and the number of antennae and tail whiskers also increases with age.

After the last molt, the larvae grow wings and emerge into adults.

Freshly molted larvae and newly emerged adults are also white and gradually darker in color, so that a species of cockroach can also change in a population according to environmental conditions. The larval stage is long, generally lasting about 30 450 days. After the larvae lose their appendages or damage their antennae, they can regenerate in the next instar after molting.

Regeneration of this type of injury also increases the number of molts.

Cockroaches will lay their eggs in dark, damp and food places and some hidden locations, especially in some more hidden kitchenware or sundries piles, cockroaches will deliberately choose this kind of place when laying eggs, and the egg sheaths laid are not easy to be found in such places.

In some hidden places, cockroaches will do related work after laying eggs, before laying eggs, they will bite the surface of the object where they are ready to lay eggs into a depression, and then lay their eggs in this depression position, after laying eggs, cockroaches will use their own sticky saliva mixed with bitten wood chips or paper and other powders to mix together, and the depression on their eggs will be completely covered, so that people are not easy to find the existence of cockroach eggs.

If you see cockroach eggs, you can boil a pot of boiling water and pour them on them, or burn them with fire.

Pay attention to cleaning the house in daily life, take out the garbage frequently, keep the room clean, you can sprinkle special cockroach medicine on all corners or crevices of the house, if the cockroach lays eggs, and when the eggs grow into adults, they will take these medicines, and then kill the cockroaches.
