CATDOLL : CATDOLL: How do cockroaches reproduce?

1. How do cockroaches reproduce?

Cockroaches reproduce by a combination of sexual and asexual reproduction.

Cockroaches reproduce by combining sexual and asexual reproduction, and the vast majority of cockroaches practice female-male mating. After mating, one or more pod-like things will grow at the end of the female cockroach's tail, which are called oothecaes, in which the eggs are laid. One ootheca can hatch 10-50 cockroaches.

Cockroaches generally only mate once in their lifetime, and each mating lasts up to 2 hours, so they can reproduce throughout their lives, even asexually.

Cockroaches are metamorphosing insects. Their entire life cycle goes through three stages: egg - nymph - adult. It takes about 60-500 days for a cockroach to grow from a nymph to an adult.

Cockroaches are omnivorous insects that eat a wide range of food. They like to eat all kinds of bread, rice, cakes, cooked meat and vegetable foods, and they especially like fragrant, sweet, and oily pasta.

Are cockroaches hermaphrodites?

The cockroach has a flat body, dark brown, and is usually medium-sized. It has a small, mobile head. Its antennae are long and filamentous, and its compound eyes are well developed. Its wings are flat, with leathery forewings and membranous hindwings. The forewings and hindwings are roughly the same size, covering the back of the abdomen.

Usually a female cockroach can produce dozens of egg cases, and each egg case can hatch dozens of baby cockroaches, so even if the female cockroach is stepped on to death, the remaining cockroach eggs will still grow into baby cockroaches under suitable temperature conditions. Generally, the climate in the south is more humid than in the north, and cockroaches appear more frequently than in the north.

Male and female cockroaches are different bodies. They are dioecious creatures. Male and female adult cockroaches can mate about a week after emerging from their pupae. Generally, male cockroaches can mate many times in their lifetime, but female cockroaches only need to mate once or twice to produce fertilized eggs throughout their lives. After mating, a bean pod-shaped thing called an ootheca will grow at the end of the female cockroach's tail, and the eggs are laid in it.

2. How do cockroaches reproduce?

It is the German cockroach.

The German cockroach is the smallest indoor cockroach, with a body length of only the size of a soybean, about 1 cm to 1.5 cm, and a dark brown color. It is native to Africa and was first discovered in Germany, sneaking into China along with the circulation of goods.

It has a strong reproductive capacity and a most ruthless trick - the female cockroach carries the egg case with her, so even if she is stepped on or slapped to death, the egg case is not destroyed and she will still reproduce the next generation. This allows it to win over other cockroaches with its numerical advantage.

Additional information:

The first measure for residents to prevent and control cockroaches is to manage the living environment, remove debris, and then "block holes and fill cracks" to reduce the living space of cockroaches. If cockroach egg cases are found, they must be removed immediately. Secondly, it is inevitable to use pesticides.

At present, common cockroach killing drugs include cockroach killing chalk, fumigation tablets, special cockroach killing aerosol cans, etc., and the main ingredients are pyrethroids. After using the above methods, use the more expensive cockroach killing glue bait to "targetedly eliminate" the remaining cockroaches. After this combination of punches, the cockroaches can basically be partially exterminated.

If it is a large place such as a guesthouse, office building, food industry, etc., professionals are required to use relatively professional equipment and technical means.

3. How are cockroaches produced? Analysis of the causes of cockroach production

1. The house is too humid: Pay attention to whether the wooden door frames, doors and windows, the bottom and back of cabinets, and relatively cool places where items are placed for a long time have been soaked and become rotten and damp.

2. Poor hygiene conditions at home: expired and spoiled food, and garbage not cleaned up in time, leading to the breeding of cockroaches.

3. There are many trees nearby: There are too many trees planted in the community where you live, so they grow lush and tall, which is suitable for the reproduction and growth of cockroaches.

4. Temperature reasons: Cockroaches like to appear in warm climates, which is also the peak period for cockroach reproduction. The warm climate allows cockroaches to survive easily.

4. How long does it take for cockroaches to reproduce?

The answer is 7-10 days. The life span of cockroaches is about 2 years. A mature female cockroach can produce an ootheca containing 14-40 eggs every 7-10 days. The eggs are dark brown and look like small bean pods. A female cockroach can produce hundreds of thousands of offspring a year, up to a million. Even if there are no male cockroaches, female cockroaches can reproduce asexually for three generations in a row.
