Aphids?
They are small and soft, about the size of a pinhead. There are tubular protrusions on the abdomen, and the overall body shape is small and exquisite, like a bud that has just sprouted. In addition, aphids like to suck the juice of buds, so they are called "aphid" insects. They are also known as melon aphids, greasy worms or honey worms. ?
Aphids belong to the order Hemiptera (formerly Homoptera), including the superfamily Adelgoidea and the superfamily Aphidoidea. Aphids are mainly distributed in temperate and subtropical areas of the northern hemisphere, with few distribution in tropical areas. At present, there are about 4,700 known species in the world, and about 1,100 species are distributed in China. ?
The English name of aphid is aphid?, also known as plant?louse, greenfly or antcow. It sucks plant sap and is a major pest of plants. It not only hinders plant growth, forms insect galls, and spreads viruses, but also causes deformation of flowers, leaves, and buds. The life history is complex. The wingless female (stem mother) reproduces parthenogenetically in the summer, giving birth to ovoviviparous aphids. When the aphids on the plant are too dense, some grow two pairs of large membranous wings to find new hosts. Female and male aphids appear in late summer. After mating, the female aphid lays eggs and overwinters with them. There may be no egg stage in warm areas. Aphids have wax gland secretions, so many aphids look like white wool balls. It can be controlled with pesticides or natural enemies (ladybugs, aphids, lacewings, etc.). Ants protect aphids from weather and predators, move aphids from dead plants to healthy plants, and tap aphids to obtain honeydew (the sweet liquid secreted by aphids).
