According to Dr. Vu Duc Chinh, Head of Entomology Department (Central Institute of Malaria – Parasitology – Entomology), earth cockroaches are arthropod insects with hard shells, so they are very difficult to destroy. Some Chinese documents say that earth cockroaches are effective in Oriental medicine to treat diseases. However, in Vietnam there is currently no research on this issue. “Just like the golden apple snail and the red-eared turtle, when imported, the future harm cannot be foreseen. Therefore, Vietnam’s quarantine agency needs to strictly control ground cockroaches,” Dr. Chinh recommended.

Faced with the threat of earth cockroaches, the Institute of Ecology and Biological Resources (Vietnam Academy of Sciences) sent scientists to collect take samples for analysis. Associate Professor, Dr. Khuat Dang Long, Department of Insect Ecology, Institute of Ecology and Biological Resources, shared: “Cockroaches are insects that often have uncontrollable pathogens. People can chase after immediate profits, the benefits are not yet visible, but the harm is always a potential danger lurking.”

Earth cockroaches mainly live in soil. If raised manually, it is necessary to prepare well to handle cockroaches to be able to keep warm in the winter. In the summer, when they go to avoid the heat, you need to pay attention to good soil so that the ground cockroaches can absorb water and food to nourish their bodies.

 

According to a farmer, every 1kg of cockroach eggs is equivalent to 2,000 egg cocoons. Each cocoon will hatch 8 children, so each kilogram of cockroach eggs can give birth to up to 16,000 cockroaches. And from each kilogram of cockroach eggs, up to 40-50kg of dry cockroaches can be obtained. Cockroaches have 3 stages of growth like sesame seeds; The soybean-shaped type and the pea-shaped type are adult cockroaches.
