Juveniles are sexually mature from 9 months to 10 months of age, and are 2 years old to 3 years old. Every year from mid-February to late April is the breeding season of cockroaches. The maternal estrus period is 10 days to 12 days, and the estrus is prosperous from 2 days to 4 days. Mating should be carried out during estrus.
The estrus mother estrus is only estrus once in the estrus season, so it is necessary to make estrus identification so that breeding can be done in a timely manner to prevent missed opportunities and create empty feelings. The method of estrus identification can be observed in the following three aspects: mental state (stand esteem, loss of appetite, frequent activities), genital changes (inflamed vulva, labia valgus, and secretion of mucus), put the test situation (if the mother There is no estrus, and when you put it right, you have to sit and ignore yourself, and even open your mouth to bite the male cheating; if you have a good estrus mother, you can quickly get close to the public squawk or lift the tail to accept the mate.)
Mating mating females into a male cage can be paired twice a day. If you haven’t mated after 30 minutes to 40 minutes, you should immediately change your salary until you mate. The cockroach's mating action is that the mother-in-law is lying on the cage net, then turns over, and the abdomen faces upwards. The mating time is generally 6 minutes to 12 minutes, and the maximum is 25 minutes. After the initial allocation, 12 hours to 24 hours after the compounding, it should be compounded 2 times -3 times. If there is sufficient public money, 2 males and 1 female can be used to increase the conception rate.
Matching should adopt the principle of “big allocation, large distribution, medium and small distribution, and good distributionâ€. Prevent close relatives (no blood relations in the last three generations) to mate. Inbreeding prone to adverse consequences such as stillbirth, deformity, congenital deficiency, acquired vitality, and reduced fertility. The ratio of male to female cockroach should be 1:3-1:4. In the trial or in the breeding process, care should be taken to protect public funds and prevent them from being bitten by their mothers.
