Description

Technical Field

[0001] The invention relates to the technical field of insect breeding, and in particular to a device for collecting egg sheaths of American cockroaches. The invention also relates to a method for collecting egg sheaths of American cockroaches. Background Art

[0002] Blatta, commonly known as cockroach, belongs to the order Blattaria of the class Insecta. This group is widely distributed, reproduces quickly, has a varied diet, and has strong adaptability. It is one of the oldest and most successful insect groups in the world. Medicinal material Blatta is a traditional Chinese medicine for promoting blood circulation and removing blood stasis. It is recorded in the "Shennong Bencao Jing" and "Bie Yi Minglu" and other ancient herbal works and local drug quality standards in Yunnan, Hunan and other provinces. The 2005 "Yunnan Province Chinese Medicinal Material Standard" (Volume 1) records that the nature and flavor of cockroach are salty and flat, and it enters the heart, liver, spleen, and kidney meridians. Oral administration has the effects of strengthening the spleen and eliminating malnutrition, promoting blood circulation and unblocking meridians, promoting diuresis and reducing swelling; external use can reduce swelling and promote tissue regeneration, and is used for burns caused by water or fire, various wounds and ulcers. It is one of the typical animal medicines.

[0003] The American cockroach (Periplaneta americana Linnaeus) is the most widely used and mainstream species in the cockroach group. The American cockroach belongs to the order Blattaria, family Blattaria, genus Periplaneta, with a body length of 27-40mm. It is the largest group in the family Blattaria and is distributed in most parts of the country. In the early days, it was mainly captured manually as a source of medicine. In recent years, with the production of drugs such as Xinmailong Injection and Kangfuxin Liquid, as well as the development of American cockroach health foods and daily chemicals, the previous artificial capture collection method is far from meeting the growing demand for raw materials. People have tried to artificially breed American cockroaches and have succeeded.

[0004] As breeding workshops and breeding scales expand in various places, how to improve breeding efficiency has become the key to efficient breeding. The current problems faced in production are: (1) When collecting eggs, it is necessary to remove the egg sheath collection device from the breeding rack to collect eggs, which is very time-consuming and laborious; (2) American cockroaches are omnivorous insects. Even if there is sufficient food, American cockroaches like to drill through the flat gaps of the egg sheath collection device to gnaw on the eggs, which seriously affects the survival of the eggs. The existing egg sheath collection device cannot solve the problem of adult cockroaches eating eggs. These two problems seriously affect the breeding efficiency and need to be improved.
