Cockroaches are one of the most disputable species of insects. Generally in them see only one continuous harm. They settle in the apartment, breed with an inconceivable speed and are a source of nervous breakdowns at many ladies who face them in kitchen or even in the room. All know that cockroaches quickly breed. However very few people know how all this occurs. And such information is capable to help with an issue of disposal of these insects.
Official statistics claims that today on the earth about 4500 species of cockroaches live. And all of them are absolutely different. People on a bigger measure deal with two types – black and red. This two species of insects most of all like to live in premises.
Ways of reproduction of cockroaches
There live these insects the whole colonies in this connection processes of fertilization of females and removal of posterity at them are solved quicker than if they coexisted parno. In favorable conditions – heat, darkness, availability of water, etc. – the quantity of cockroaches increases in a geometrical progression. Also there is it all the year round.
Process of fertilization happens according to the same scheme, as at many animals. At first a female with a male sniff at each other short moustaches, then lick each other and copulate. By detailed consideration it is possible to find a genital plate which consists of two symmetric grifelk in adult males. Eggs of a female are laid in the special capsule which is called hypostasis. Domestic cockroaches, unlike forest, do not hide this capsule, and drag with themselves. Because hypostasis enough big sizes, it are well visible.
In one hypostasis quite large number of eggs – from 12 to 60 is located (depending on a species of a cockroach). Speed of reproduction red much quicker, than at black.
Extent of incubation of "pregnancy" of a tarakanikhama every time different since very strongly depends on external factors. Process can take from 60 to 180 days.
Black cockroaches can bear posterity and up to 2 years. If conditions adverse process of "pregnancy" is dragged out up to 3-4 years.
One female has an opportunity "to give birth" about 22 times for the life. Other adult individuals help to adapt to larvae in the first weeks of life. There is also one more pregnancies option of a female of a cockroach. For this purpose to her it is not obligatory to copulate every time with a male at all, there is enough also the first time.
How to destroy cockroaches
It is possible to struggle with cockroaches independently, but it is better to resort to the help of professionals nevertheless. First, at them and means will be more powerful. Secondly, they know some features of any given species of insects and as they can be destroyed effectively. It is possible to direct efforts to fight against pregnant females. For this purpose it is enough to press of them. Besides, it is worth understanding that eggs of others will hatch sooner or later. And it can be traced since sometimes cockroaches throw the unnecessary covers in crowded places. As small tarakanchik practically, except the sizes, differ in nothing from adults, it is possible to poison them with habitual means. So, for example, they eat the same food, as adults. And it means that it is possible to leave for them the poisoned products and to pour powders in places of their dwelling. It will hardly prevent to breed to new cockroaches, but there is a hope that due to the massive attack the most part will die.
