How to breed bugs, bug breeding technology?

First of all, there are heteroptera, backstroke bugs, nearly 200 species. The length is generally less than 15 mm, the head is ovate, and the body is elongated. When swimming, the back is turned down and the back is raised like the bottom of a boat; The feet are long and the paddling is like a paddle.

The back is light in color, and when viewed from below, it is indistinguishable from the water and the sky; The rest of the water is dark and does not distinguish from the bottom of the water when viewed from above. This is a type of hidden color (reverse coloring).

Its body is lighter than water, and it can float up as soon as it lets go and grasps the underwater plants, and when it reaches the surface, it can jump out of the water and fly away, or store air under the wings and around the body before sinking into the water. When floating on the surface, the feet are extended, and they can paddle immediately when they are frightened. Feeds on insects, tadpoles and fish, and the catch, which is usually larger than its own body and sucks its bodily fluids.

It is characterized by stinging and sucking mouthparts insects that prey on small aquatic organisms such as tadpoles and small fish. When predating, the mouthparts like pins and needles are pierced into the prey, neurotoxins are injected to paralyze them, and digestive enzymes are injected to decompose the internal organs of the prey before sucking.

Backstroke bugs live upside down. They live in ponds and ditches, floating in the lower layers of the water's surface, waiting for other insects to fall to the surface. When an insect arrives, the backstroke curl will paddle towards it with its back foot as an oar.

Then, with its sharp mouth, it stabs its prey from the bottom up. To ensure breathing, backstroke bugs will conserve some oxygen around their bodies.

Habits. The adult of the nine-spice insect has wings and can fly, and its host plants are mainly cucurbitaceae, such as various melons such as pumpkin, winter melon, watermelon, loofah, water melon, etc.

Newly hatched nymphs (larvae) are mostly found in the crevices and leaf buds and petioles of the host plant, and inhabit the curly yellow dead leaves.

The nine spice insects feed on the sap of the host plant, and the adults overwinter under the soil and stones, in the crevices of stones, in the melon shed or in the cracks of the walls.

Adults can mate many times in their lives, lay eggs on the inside of the green leaf sheath, in rows and side by side, as little as 2-3 grains, more than 8-9 grains or more than 20 grains, and the female worm produces more than 50-10o eggs. The adult worm has a lifespan of 30-30 days, and the male worm is slightly shorter. The average daily temperature is 19 4 days and the egg period is about 45 days, 24 1 23 days.

The nymphs have a total of 5 instars, the average daily temperature is 24 hours, and the nymph stage is 50 days.

Jiangsu and Zhejiang have 1 generation, 2 generations in Jiangxi, and 2-3 generations in Guangdong. Adults and a few instar nymphs overwinter under stones, 5-10cm in soil crevices, or in the rhizosphere of weeds, between rice piles, and in bark crevices. In the early summer of the following year, it emerges and swarms on the rice.

Adults and nymphs like to lurk at the base of the rice bush near the water surface in the clear day, and go to the leaves or ears in the evening or cloudy day to suck, and lay the eggs on the leaf sheath of the rice plant 6-9cm from the water surface, and the egg masses are mostly composed of 14 grains, arranged in 2 rows. 75 eggs per female. The early sowing fields with vigorous growth and dark green leaves are heavier in hilly and mountainous ridge fields.

The natural enemies mainly include rice bugs, black egg wasps, Beauveria bassiana, spiders, frogs, etc.

Due to their different feeding habits, terrestrial Tsubaki habitats are also different, and carnivorous Tsubaki do not have a particularly fixed prey, so they are all likely to be seen among plants. Amphibians and aquatic elephants usually live in still waters, such as ponds, swamps, lakes and other environments, and their whereabouts can be easily found.

Most terrestrial Tsubaki elephants feed on the sap of plants and use the plant as their habitat.

The word "Tsubaki" is basically no longer used, it is a hemipteran insect (pentatomidae; stinkbug). This is a large group of insects, obviously can not say what plants grow on, can only be summarized in this way: common species such as rice black bug, rice brown bug, rice green bug, rice small red man bug, mainly for the damage to rice; lychees, bugs, hemp bugs, and tea-winged bugs are mainly harmful to fruit trees; Vegetable bugs, short-horned melon bugs, and fine-horned melon bugs are mainly harmful melons and vegetables; In addition, such as bugs, warbugs, bugs, etc., they hunt other molluscs for food.

The common species in China, such as rice black bug, rice brown bug, rice green bug, and rice small red man, are mainly harmful to rice; lychees, bugs, hemp bugs, and tea-winged bugs are mainly harmful to fruit trees; Vegetable bugs, short-horned melon bugs, and fine-horned melon bugs are mainly harmful melons and vegetables; In addition, such as bugs, warbugs, bugs, etc., they hunt other molluscs for food.
