How to eradicate aphids on flowers

The radical cure methods of aphids on flowers are: manual elimination and washing powder water.

1, manual elimination

Early detection of aphid pests, the number of aphids is not so much, you can take the way of grasping by hand, put on gloves to drive away aphids on branches and leaves and then pinch them to death or stick them with needles and toothpicks.

Only a single or a small number of branches and leaves have aphids, and these branches can also be cut off and thrown away to prevent aphids from spreading to other healthy branches and leaves, and then some washing powder water can be sprayed to take preventive measures to prevent "insects" that escape the net from continuing to harm plants.

2, washing powder water

Washing powder water, soapy water and detergent water have good control effects on aphids. When aphids are found on plants, first use 2-3g of washing powder, then add about 100g of water, stir well and spray on the front and back of branches and leaves for 2-3 times, which will take effect. Some flower friends will also add a small amount of urea to the washing powder, and the effect will be better.

Life habits of aphids

Aphids have tubular protrusions (abdominal tubes) on their abdomen. Aphids have a pair of abdominal tubes, which are used to discharge defense fluids that can quickly harden. The composition is triglyceride. The abdominal cavity tube is usually tubular, long and usually wide, with a thick bottom. They suck plant juice and are large plant pests. It not only hinders the growth of plants, forms galls and spreads viruses, but also causes deformities of flowers, leaves and buds.

With a complicated life history, the wingless female (〔stemmer〕) parthenogenesis in summer, viviparous and gives birth to young aphids. When aphids on plants are too dense, some will grow two pairs of large membranous wings to find new hosts.

In late summer, female aphids and male aphids appeared. After mating, the female aphid lays eggs, overwinters with them, and finally produces a godmother. Warm areas can have no egg period. Aphids have wax gland secretions, so many aphids look like white pompoms.
