Silkworm silkworm disease is the enemy of the sericulture industry. There is no medicine to cure, and its spores are hidden in dark corners. Therefore, it is necessary to identify and prevent silkworm particle disease early.
Identification of silkworm granulosus disease can be observed in different stages of different performance: in the embryonic, silkworm eggs appear a large number of irregularly arranged eggs, stacked eggs and anaerobic eggs, poor adhesion, easy to fall off; hatching, hatching does not Qi, not sparse for several days, small body shrinkage, dark complexion, eating mulberry, action is not lively, late, late or weak skin, into a half silkworm silkworm or sealing silkworm; in silkworm stage, body with rust color , The shape of the rotten rotten is not perfect. It dies in the breeding process, and the dead body rots less. In the silkworm stage, there are many dark brown spots of different sizes on the surface of the body, mostly on the ventral sides or the tips of the tail, like peppers. In the same way, some tails are coked, silk glands are not bright, milky yellow protrusions appear, and when the disease is heavy, they cannot be spit, and can only cause knots, moths and cockroaches are also abnormal.
In order to avoid the spread and harm of silkworm microscopic disease, besides observing and observing every day, if there are signs of microscopic disease appearing in silkworms, they must be eliminated strictly, and medicines should be used for prevention. For silkworms before 3 weeks of age, they can be fed with carbendazim and 0.3% available chlorine bleaching powder; in the silkworm era, 0.8% available chlorine bleaching powder can be used as a silkworm body for daily disinfection; The available chlorine bleaching liquid is hand sanitized before and after sand removal; all silkworms should be exposed to outdoor exposure and sterilized with 1% available chlorine bleaching liquid; and the dead silkworms, silkworm sands and garbage should be kept away from the concentrated concentration of silkworms. , Can only be used as fertilizer after being fully cooked.
