How are slugs formed? The origin of the slug, what is it?

How do slugs form and reproduce?

Slug formation process:The slug, or slug, is a mollusk (a mollusk), from which the snail is transformed, and is a mollusk that, together with some snails, has a pulmona. Hermaphroditic, looking like a shellless snail, oval oval, tough and elastic, 2 in diameter.

The nucleus is visible in white and transparent, and the color becomes darker near hatching. The larvae are 2 long, light brown in color, and the body shape is the same as that of an adult.

Reproduction process:2-6 generations per year, hermaphroditic, allogeneic fertilization or hermaphroditic fertilization reproduction, egg laying, egg period 10-17 days, larval stage 55 days, nocturnal activity, daytime latent, hunger tolerance can reach more than 130 days.

Sluggs are transformed from snails to reproduce as eggs.

Hermaphroditic, mating and laying eggs, the eggs are laid in moist soil. Latent in the crevices of cool and moist soil, plant rhizosphere and other places for summer. The egg stage is 10 to 17 days, and the larval stage is 55 days.

In late September, when the temperature drops below 24, it becomes active, and October and November are the second feeding and spawning season.

The formation of slugs (also known as slugs) is: allogeneic fertilization or homogeneous fertilization and reproduction, laying more than 400 eggs, egg heaps are laid in moist soil, the egg period is 10-17 days, and the larval stage is 55 days. In spring and autumn, the damage is serious.

From April to June, the most severe damage was made, and from May to July, the Yangtze River basin suffered the most. Wild slugs [pinyin kuo yu] are nocturnal, lurking during the day, and can withstand hunger for more than 130 days.

Lives in dark, damp places, lurking during the day, and going out at night and in the rain. Hermaphroditic, mating and laying eggs, the eggs are laid in moist soil. It feeds on the young leaves and shoots of plants, and is the enemy of vegetables, fruit trees, tobacco, cotton, etc.

A common species in China is the yellow slug. Large, with a body length of up to 120 mm when extended. The body is yellowish-brown or dark orange with light yellow spots.

Likes to eat plants, is a pest of agriculture. Abroad spends an average of $30 million a year to eradicate them.

1, slugs from the snail to 2 to 6 generations per year, hermaphroditic fertilization or homogeneous fertilization reproduction, more than 400 eggs, egg heaps laid in the moist soil, egg period 10 to 17 days, larval period 55 days, spring and autumn occur serious damage, 4 to 6 months the most intense, the Yangtze River basin 5 to 7 months is the most serious, wild slugs are nocturnal activities, daytime latent, hunger resistance can reach more than 130 days.

2, slugs are also known as slugs, slugs are afraid of light, 2-3 hours under strong light that die, so they are nocturnal activities, starting from the evening, reaching the peak at 10-11 o'clock in the evening, before the early morning and successively diving into the soil or hidden places, strong hunger resistance in the lack of food or bad conditions, can not eat and do not move, the dark and humid environment is easy to occur, when the temperature, soil moisture content is 20-30, it is the most beneficial to its growth and development.
