The substratum slender cylindrical, 4-7 cm long, about 0.3 cm in diameter; surface dark brown to brown, with fine longitudinal wrinkles, the upper part is slightly inflated; texture pliable, cross-sectional whitish, fibrous. Smell slightly fishy, taste slightly bitter.

Growth habit of Dong Chong Xia Cao

The larvae of the host bat moth of Dong Chong Xia Cao encounter the ascospores of Cordyceps with the help of wind or rain, and are infested when the environmental conditions are suitable, the infested larvae move slowly and die near the surface in October at 2-9℃. From November to February, when the ground temperature is extremely low, the growth of ascospores is very slow or even stops; in May, when the temperature rises to 4-10℃ and the soil thaws, mycelium grows on the surface of the stagnant insects and adheres to the soil to form a membrane skin, and the ascospores grow rapidly upward to 20-50 mm rod-shaped ascospores. -In June and July, the head of the cotyledon gradually expands, and the ascospores mature and eject under suitable temperature, humidity and light, at which time, the subterranean stiletto rots, the cotyledon hollow, and the spores spread out to infect bat moth larvae again with wind and water. In the natural state, it takes about 3 years for Cordyceps to complete the asexual and sexual generations.

Pest control of Dong Chong Xia Cao

There are more pests and diseases that can occur in the cultivation process of Cordyceps sinensis, with as many as 20 known species. Pests and diseases mainly focus on the host insects, including fungi, bacteria, nematodes, parasitic insects, predation by natural enemies and mechanical damage, of which the highest death rate is caused by infection with germs, while parasitic insects and nematodes occur less frequently, and there are generally no natural enemies in indoor breeding. Mechanical damage is more common, although it does not cause direct death, but the wound is easy to infect the germs, resulting in the death of the host insect.


The disease is divided into fungal and bacterial diseases. The common pathogenic fungi are Penicillium mimicum, Green Sclerotinia, White Sclerotinia, Red Sclerotinia and so on. There is no effective and safe control agent for the disease, prevention is the main focus, integrated prevention and control, advocate pollution-free feeding, mainly should control the microorganisms in the environment of artificially reared bat moths. The indoor environment should be fully disinfected, the worm room should be fumigated and disinfected, eggs, water, feed and other materials entering the worm room should be disinfected and sterilized first, and the equipment and containers used for worm breeding should also be disinfected regularly to reduce pathogenic bacteria and parasites entering the breeding environment. Ensure feed supply, enhance worm resistance, check at all times, find and reject diseased and dead worms in time to prevent the spread of disease; actively screen the stock with high disease resistance, and promote crossbreeding to prevent stock degradation. In addition, breeding personnel should also pay attention to personal hygiene, disinfection work to prevent cross-contamination.

Insect pests

Insect pests include mites, nematodes, mosquitoes, parasitic flies, parasitic wasps, etc. The proportion of nematodes is small and parasitic pests rarely occur. After harvesting, remove the surface impurities and sediment to remove the mites (eggs) on the surface; process the herbs to reduce the water content to less than 15% to make the mites (eggs) die; keep the environment dry and clean during storage to avoid the entry and growth of mites. The herbs should be packed in sealed bags, preferably in inflatable packages to avoid mite infestation.
