What harm do slugs do to shiitake mushrooms? Please explain
Slugs hide by day and feed in groups at night, after rain and on overcast days. They reproduce once a year. Eggs are laid inside the inoculation holes of the mushroom bags, 10 to 20 per cluster. They often live in dark, damp grass, under fallen leaves or beneath soil and stones. The suitable temperature is 15 to 25°C; above 26°C or below 13°C, their activity is poor. The optimum temperature for egg laying is lower than that for activity; when the soil temperature stays stable at around 9°C, they can lay eggs in large numbers, and above 25°C they cannot lay eggs. A soil humidity of around 75% is suitable for egg laying and hatching. Damage pattern: wherever slugs crawl, they leave trails of white, glistening slime and their excrement. They can eat the fruiting bodies of shiitake mushrooms, biting them into notches and damaging the tissue; sometimes the damaged spots also become infected with mold and bacteria.
