Control techniques of Chinese wolfberry aphids

The most important pest of Chinese wolfberry in planting is aphids, which can occur for 15 generations a year in a suitable environment, with strong fecundity, which will lead to tree weakness, yield decline, and seriously affect the economic benefits of growers. So how to control Chinese wolfberry aphids? Let's take a look at the detailed introduction.

1. Symptoms

Aphids also need honey and greasy worms, which begin to break out from April to May every year, and can reproduce several generations a year with strong fecundity. during the attack, larvae and adults gather in the leaves and constantly suck the sap of the leaf tissue, which makes the leaves deform and atrophy and the tree is weak. It leads to the decrease of leaf photosynthesis and the decrease of synthetic nutrients, which leads to the growth of flowers and fruits without sufficient nutrients, which leads to the decrease of fruit setting rate and yield, and the fruit does not have sufficient nutrients to grow and the quality is low.

2. The regularity of the disease

The period of aphid outbreak is from April to May, when there are dense aphids on each branch of the plant. in the period of high temperature in summer, the density of aphids decreases, but there are still a small number of aphids left in the branches. in autumn, the aphids on the new shoots will rise again and continue to do harm. Until November in winter, due to the drop in temperature and food shortage, male and female aphids began to produce male aphids, so after mating, female aphids began to lay eggs between the branches, so that after winter, the eggs began to hatch and continue to harm.

3. Prevention and control methods

In early spring and late autumn, the residual branches of the plant, the branches of disease and insect pests and the dead grass and fallen leaves of the garden can be trimmed and burned out of the garden to reduce the source of diseases and insect pests. Once in the garden in spring, the source of overwintering insects can be greatly reduced. When aphids break out, artificial hunting can be used, or branches with aphids can be pruned. It can also be controlled by using the natural enemies of aphids. Small flower bugs, lacewings, ladybugs, aphid cocoon wasps and aphid flies are the natural enemies of aphids, which can protect them and control the number of aphids.
