Life cycle and gestation period of cockroach

The life cycle of cockroaches is really impressive, since they have ancestors who lived about 300 years ago, before the same dinosaurs, so are animals with easy adaptation, since before the weather was very warm , cockroaches can live longer than you think thanks to these faculties.

However, cockroaches prefer warm, humid climates, although these only require basic survival as things are water, food, shelter and warmth as they easily adapt to different environments.

Its high reproductive rate and variability in different species makes cockroach pests very difficult to eliminate completely. It is even considered that cockroaches would be the only ones that would survive on the planet after a destructive nuclear war. Let’s know all the details about the gestation of the cockroach and let’s reveal what is fiction and what reality.

Sexual maturity and mating of the cockroach first phase of gestation period

The adulthood of cockroaches can reach from 5 to 15 months of age, when these insects complete their last cycle of mutation. From this moment on, both females and males are ready to reproduce.

Cockroaches are insects with nocturnal habits, so they mate mainly during the night. The females attract potential sexual partners through the segregation of pheromones from their body. Some cockroach species can perform simple courtship rites, raising their wings to exhibit the dorsal membrane and also expand the genital canal to receive the male. The males in turn respond to this invitation by waving their wings.

Cockroaches have very little developed sense of sight, so they use their antennae to recognize the land and establish contact with their partner during the copulation. The act ends when the male deposits the sperm inside the female.

A curious fact in this species, is that not necessarily the females need a male to have their offspring. In scientific experiments in laboratories it has been proven that in the absence of males, female cockroaches can opt for an asexual reproduction, specifically a reproduction by parthenogenesis. This differentiates them significantly from the rest of the insects, which are not able to reproduce with only one parent.

Gestation period of the cockroach

The gestation time of the cockroach is very variable, there are prolific species that only take 1 month to see their young born and others can take around 10 months in the process. Let’s see some of the most representative examples:

  • American cockroach: from 24 to 38 days
  • German cockroach: 1 month
  • Brown band cockroach: 3 to 6 months
  • Oriental cockroach: 300 days

In all species, once the cockroach has been fertilized internally, gestation begins. It is at this moment that the female creates a capsule called ootheca, an egg deposit covered with an organic protection, secreted by the mother. The cover of the ootheca becomes a thick protective layer within a few days of its creation, which is ideal for preserving eggs safely. From this moment and according to the cockroach species, the pregnancy takes one course or another.

Birth and breeding of the cockroach, part of gestation period

Newborn cockroaches are known as nymphs and maintain this name until they reach maturity. The births of the nymphs occur without any help from the mother, the offspring alone are able to make their way from inside the egg making pressure on it.

The appearance of the nymphs is very similar to that of adults (this usually happens little with other types of insects), there are only significant differences in size, the bright white color and that as it has not expanded the thorax lack wings . To allow the growth process of the nymph it must undergo successive moulting until it finally reaches the adult size, in the latter it is finally provided with two pairs of wings.

Number of cockroach babies born in gestation period

The number of nymphs that the ootheca of a cockroach can contain is variable, some species are only able to lay 10 eggs and others like the Germanic up to 40. The usual is that the female can produce an approximate of 8 to 90 ootecas throughout its fertile life, so the average number of offspring of a female ranges between 200 and 600. There are also species of cockroaches in which the female only has a reproductive cycle throughout its life and as a result are able to produce a number of top eggs in a single copulation, in this picture you can see how the cockroach eggs look.
