What to Do If Silkworms Don't Spin Cocoons? Causes and Solutions
I. Main Causes 1. Pathological factors. For example, with pébrine or flacherie, infection and onset before mounting for spinning destroys the secretory function of the silkworm's silk glands; or the pathogen produces large amounts of toxic metabolites in the silkworm's body, paralyzing the silkworm's nerves so it cannot spin silk or form a cocoon. 2. Physiological factors. Abnormal middle silk glands, mainly caused by excessively high rearing temperatures, overly tender leaves, disordered secretory glands, etc., leading to abnormal silk glands and inability to spin. Next is abnormal anterior silk glands, mainly caused by exposure to large amounts of coal gas, fishy odors,

What to Do If Silkworms Do Not Spin Cocoons? Cause Analysis and Control Methods
I. Causes of silkworms not spinning cocoons: 1. Pathological factors. For example, pebrine and flacherie are prone to infection and disease before mounting, which destroys the silk gland secretion function of silkworms, or the pathogens produce large amounts of toxic metabolites in the silkworm body, paralyzing the silkworm's nerves and preventing them from spinning silk and forming cocoons; 2. Physiological factors. The first is abnormality of the middle silk gland, mainly caused by rearing temperature being too high or too low, leaf quality being too tender, secretory gland disorder, etc., causing silk gland abnormality and preventing spinning; the second is abnormality of the anterior silk gland, mainly because during rearing

How to judge the severity of fish gasping at the surface
To judge the severity of fish gasping at the surface, the main criteria are the time when the fish begin to gasp, the location of the gasping, the size of the water surface area where they gasp, and the species of fish gasping. 1. Dark gasping. This generally occurs when it is already daylight but the sun has not yet risen; the fish move about on the water surface in the center of the pond and on the upwind side, and bursts of splashing water can be seen. At this time the dissolved oxygen content of the pond water is 2-3 mg/L, which is normal gasping. 2. Light gasping. This mostly occurs at dawn; the fish are on the water surface in the center of the pond and on the upwind side, while wild trash fish gasp at the pond edge.

Potato spindle tuber disease
[Virus English name] Potato spindle tuber viroid [Host crops] Potato, tomato, etc. [Disease diagnosis] Diseased plants have upright stems with very few branches. Leaves are held upright, and the angle between the petiole and the stem becomes smaller; leaf margins are wavy or curl upward, and leaves are stiff and brittle with a dark green color; leaves become smaller and curl into a half-closed, twisted shape. At the bud stage, plant growth is noticeably delayed, leaf color becomes lighter and sometimes yellowed, and severely diseased plants are stunted. Tubers are elongated, or one end is more pointed, forming a spindle shape, with
