I would like to ask if there is a male or female cockroach? and how to eliminate

1. Manually hunt and kill cockroaches: you can turn over boxes and cabinets during the day, and hunt and kill when you see them. At night, after 8 o'clock, turn on the lights every 15-30 minutes to catch them, and the results are better.

In addition, while turning over the boxes and cabinets to kill cockroaches, attention should also be paid to checking the egg pods in the gaps or drawers and squeezing them.

2. Trap and eliminate cockroaches: use canned food bottles, loofahs, etc. as traps, put a small amount of rice, cakes, brown sugar and other bait, and place it in the place where cockroaches often go in and out before the cockroach is active at night, and collect and kill it the next morning.

3. Kill cockroaches by heat: cockroaches have poor resistance to heat, and when the heat reaches more than 60, they will die within a few minutes, and can kill the eggs in the egg pods. A common method is to put boiling water into a kettle and pour it into the hidden crevices of cockroaches to scald it.

When using this method, it is advisable to increase the water level and increase the water pressure, so that the boiling water can be injected deep into the gap to improve the efficacy.

4. Plugging and eliminating cockroaches: For cockroaches in hidden places, they can also be blocked with lime and sticky soil, so that cockroaches can not crawl out and eventually starve to death, and may have the effect of inhibiting the hatching of egg pods. Plugging should be carried out during the day, because the cockroaches hide in the daytime, and if they are active in all directions by night, the cockroaches cannot return to the hidden place and cause them to wander everywhere.

5. Cockroach sticky trap box to eliminate cockroaches: It consists of a viscose cardboard and a carton. The viscose cardboard is coated with a layer of cockroach viscose, the glue surface is covered with a sheet of anti-stick paper, and the trapping carton is shaped like a roof, with openings on all sides.

Tear off the anti-stick paper when using, place a small piece of sweet bread or other food in the viscose cardboard** and place the viscose cardboard in the carton. Cockroaches break into the box and are glued to the inside of the box, unable to escape. Cockroach viscose does not contain pesticides and is harmless to humans and animals.

Because cockroaches are adaptable to the environment, they are arguably the hardest creatures on the planet to go extinct.

A fertilized female cockroach produces a large number of egg sheaths in her lifetime, and the American cockroach can produce more than 50 at most, so the cockroach has strong fecundity. Every 7-10 days, a mature female cockroach can produce an egg sheath containing 14-40 eggs, which are colloidal and hatch between 20 and 37. The higher the temperature, the shorter the incubation time, at a constant temperature of 30, it only takes 20-30 days, and the longer can exceed three months.

A female cockroach can reproduce nearly 10,000 offspring a year, up to 100,000.

There must be a partial-point pull.

Use cockroach medicine. And they died. Flickering.

Cockroaches are divided into male and female.

Cockroaches are a kind of dioecious insects, that is to say, cockroaches are divided into male and female, as for the simple and effective way to distinguish their male and female, that is to look at its tail end, the male cockroach has two pairs of appendages at its tail end, these two pairs of shapes are different, there is a pair of segmented tail whiskers, and a pair of abdominal spines, as for the female is completely different from the male, that is to say, they only have one pair, and there is no male to grow this tail whisker.

Differences in body type. Male cockroaches and female cockroaches are completely different in size, males will be weaker and more slender in comparison, and feel not particularly fat, while females are just the opposite, it is particularly hypertrophied, especially wider.

Another point is that there are some special species of males, their wings may be more developed and long, or even directly cover the tail end, but in comparison, females do not seem to be so developed, their wings only reach the front half of the abdomen, as for the second half of the wings at all.

Therefore, cockroaches are not the same sex as we ordinary people think, cockroaches are also male and female, if you want to distinguish them, you can easily distinguish them from the above two aspects.

<> cockroaches are divided into male and female, how to distinguish between female and male cockroaches: 1. Male cockroaches are long and narrow in appearance, thin and small abdominal segments, wings beyond the tail end, and the number of male insects in the winter and spring (December to April of the following year) is more than that of female insects in the winter and spring when the temperature is low, and the male insects generally have a shorter lifespan than the female insects. Female cockroaches are stout in appearance, hypertrophied abdominal segments, obtuse and rounded ventral tail, and nymphs hatching from the same egg pod with wings near the caudal end.

After emergence, the females are twice as large as the males, so there are more females than males from May to November.

2. The tail end of the male cockroach has two pairs of appendages, one pair is segmented tail whiskers, and there is also a pair of small needle processes (ventral spines); Female cockroaches have only one pair of appendages at the tail end, that is, tail whiskers, without needles.

3. The body shape of male cockroaches is generally thin and slender, while female cockroaches are thick and wide. In a few species, males have well-developed wings that extend to the tail end, but females have wings that cover only the front half of the abdomen, or are wingless.

Cockroaches are hermaphroditic dioecious adults, and their external morphology is easily distinguishable.

1: Male cockroaches have two pairs of appendages at the end of their tails, a pair of segmented tail hairs, and a pair of tiny needles (ventral spines); Female cockroaches have only a pair of appendages, tail whiskers, at the end of their tail, and no needles.

2: Males are usually very thin, thin and slim, while females are thick and wide.

3: In some species, male cockroaches have well-developed wings that extend to their tails, while female cockroaches have wings that cover only the front half of their abdomen, or no wings.

Usually when they are breeding, as long as it is a female cockroach, almost seven to ten days apart, it can produce a lot of eggs, and then it takes about a month or so to hatch, if the temperature is relatively high, then the time will be effectively shortened. What's more, even if there is no male cockroach and it is in a very extreme environment, as long as it has mated once, then it can lay eggs, and then it can be hermaphroditic and lay a lot of eggs in a row.

The tail end of the male cockroach has two pairs of appendages, one pair of segmented tail whiskers, and one pair of tiny needle processes (ventral spines). Female cockroaches have only one pair of appendages at the tail end, that is, tail whiskers, without needles. Male cockroaches are generally thin and elongated, while female cockroaches are thick and wide.

If you want to get rid of cockroaches quickly and effectively, you can start by squeezing some laundry detergent where they are frequented, so that it can have a good effect. Mainly because the laundry detergent is alkaline, even if the surface of the cockroach is weakly acidic, and there are several small holes on its abdomen, if it touches the laundry detergent, then it will not be able to breathe better, and it will die in a short time.

Or prepare the soap first, then soak it in hot water, then put it in a bottle, and finally spray it on the cockroaches, the effect of this is also very good, but it will be a little hard to do, after all, there are more cockroaches, and it will be a little troublesome to clean up.

The x-dorsal plate of the abdomen of male and female cockroaches is called the supraanal plate, and 1 pair of multi-segmented tail whiskers grow on both sides of its base. The VII web of female cockroaches and the 1x web of male cockroaches are called the inferior genital plate. Male cockroaches have one pair of needles (ventral spines) on both sides of the end of the lower genital plate, which is an important feature to distinguish adults from both sexes.

Cockroaches reproduce unisexually and are not divided into male and female.

Cockroaches are extremely reproductive, and a mature female cockroach can produce an egg sheath containing 14-40 eggs every 7-10 days, and its egg sheath is colloidal and hatches between 20 and 37. The higher the temperature, the shorter the incubation time, at a constant temperature of 30, only 20-30 days, and the long can be more than three months, a female cockroach can reproduce nearly 10,000 offspring a year, up to 100,000, in extreme conditions when there are no male cockroaches, so female cockroaches can also lay eggs.

Cockroaches can mate about a week after the adult emerges, and the male can mate many times in his life, but the female only mates 1 or 2 times, and can produce eggs for life after 1 mating and fertilization. Eggs are laid in the egg sheath, due to different insect species, the number of eggs laid is different, more than a dozen to dozens of eggs, more than 50, a fertilized female cockroach can reproduce 20,000 after a year, if you see a cockroach during the day, it is possible to hide hundreds in the gaps, you can see the fertility of cockroaches and their severity The x-th dorsal plate of the abdomen of male and female insects is called the supraanal plate, and there are 1 pair of multi-segmented tail whiskers on both sides of its base. The VII web of females and the 1x web of males are called inferior genital plates.

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.

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.

Male and female adults can be easily distinguished by their external morphology:

A: The tail end of the male cockroach has two pairs of appendages, one pair is a segmented tail whisker, and there is also a pair of small needle processes (ventral spines); Female cockroaches have only one pair of appendages at the tail end, that is, tail whiskers, without needles.

B: Male cockroaches are generally thin and elongated, while female cockroaches are fat and wide.

C: In a few species, males have well-developed wings that extend to the tail end, but females have wings that cover only the front half of the abdomen, or are wingless.

Cockroaches are divided into male and female. Cockroaches belong to the dioecious animal, and their sex is generally distinguished by the size and tail end of the cockroach. The body size of the male cockroach is relatively slender, the jujube is a little smaller, and there are two pairs of appendages at the tail end of the rock mold, while the body size of the female cockroach is relatively large, and there is only one pair of appendages at the tail end.

Cockroaches like to be found in warm, humid places with plenty of food and crevices, and it is difficult to get rid of them completely.

Cockroaches are omnivorous insects, and there is almost nothing that cockroaches do not like to eat, especially oily food, and cockroaches are also known as "oil stealers".

Cockroaches also like to bite other non-food products, such as cotton wool products, paper products, leather products, etc., and are more likely to be found in places where sundries are stored.
