Brief description
A family of COLEOPTERA, Daphne genkwa with red head, mouth down, almost perpendicular to the body, and thin neck. Antenna 1 1 node, filiform or serrated. The chest is generally narrower than the base of COLEOPTERA, as long as the ventral end, or shortened to expose most of the ventral nodes, with soft texture, and the ends of the two wings are separated and not folded. Slender feet. Undergraduate insects have metamorphosis. There are about 2300 species in the world, which are widely distributed all over the world. More than 65,438+030 species have been recorded in China. If frightened, it will secrete a yellow liquid [cantharidin], which has peculiar smell and toxicity to "repel the enemy". It is a very greedy and active insect, and is sometimes mistaken for a firefly. It likes to eat leguminous plants, wild amaranth, nightshade, ferns and other plants. Often appear in groups, and courtship behavior is also very interesting. Usually, when the male bean sprouts see the female bean sprouts that are flirting with each other, they will climb on each other first, wrap their tentacles around the female insect's tentacles, and constantly shake, rub and flirt. When the female swings with the rhythm, the male will continue to rub the back of the female before mating.
Appearance characteristics
Red-headed root-knot nematode, a kind of root-knot nematode, commonly known as Celosia cristata, COLEOPTERA, root-knot nematode. Small and medium-sized, body length 11-kloc-0/7 mm, red head with1wide black longitudinal band; The front chest and COLEOPTERA are black, and both sides of the front chest backboard are covered with spirit hairs. The central stripes of the front chest backboard, the inner and outer edges of COLEOPTERA and the central narrow longitudinal zone are also composed of spirit hairs. Daphne odora adults like to eat paulownia leaves and bean leaves, and larvae feed on bamboo locust eggs, which is the natural enemy of bamboo locust. A Daphne odora larva can eat 60 ~ 120 eggs in a lifetime, which can effectively control the harm of bamboo locusts. The worm is produced every year, usually in the middle of June every year. When the adults are unearthed, they first fly to paulownia trees in groups to feed, especially the leaves of paulownia. After the leaves of paulownia are eaten up, they will spread out and harm low plants such as vegetables. Once it happens, it should be reported to the forestry or agricultural departments in time, paid close attention to and prevented in time. Common pesticides such as isocarbophos and trichlorfon can be killed.
Extended introduction
In adzuki bean, ginkgo flavone is mainly stored in the gonads and eggs of male insects. Compared with the average content of amphotericin in the wild population, the newly mated male worm lost 70% of its body, and the content of its female mate increased by 43%. Red-headed soybean seeds can be used as Chinese herbal medicine. After drying at 1 10℃, the content of sesamin extracted by acid hydrolysis was 4 times higher than that by direct extraction.
