Control methods of Chinese wolfberry aphids, master the law of disease, and control aphids in three steps.

Aphids are pests specially distributed in the planting area of Chinese wolfberry. They gather in groups to suck juice on the back and rhizome of delicate leaves of Chinese wolfberry, thus destroying the nutritional composition of Chinese wolfberry and affecting the flowering and fruit-setting rate of Chinese wolfberry. And the reproductive capacity of aphids is very strong, if not dealt with, it will seriously affect the economic benefits of fruit growers growing Chinese wolfberry. Next, I will introduce the law of aphid outbreak of Chinese wolfberry and the methods of prevention and control.

Morbidity regularity

The outbreak period of aphids is usually when Chinese wolfberry sprouts in April, gathering in groups on the back of leaves and roots of Chinese wolfberry leaves, and the damage continues until summer. Under the influence of high temperature in summer, the number and density of aphids will decrease a lot, but there will still be a small number of stubborn aphids on the back of branches and leaves, and then in autumn, the number of those aphids will rise and there will be a second peak. Continue to destroy the growth of Chinese wolfberry trees. In winter, when aphids run out of food, male and female aphids will combine to lay eggs, lay eggs between the root branches of the branches, and so on survive the winter, and then come back to continue its destruction after hatching in spring. This is the incidence of aphids throughout the year.

Symptoms of onset

Aphids have a very strong ability to reproduce. Every April, larvae and adults gather densely on the leaves and rhizomes of the leaves, constantly sucking the sap in the leaves, affecting the absorption of nutrients by Lycium barbarum trees and causing the loss of nutrients in the leaves. Become shrunken and deformed. Moreover, the dense accumulation of aphids in the leaves will also affect the photosynthesis of the leaves. The branches of the Chinese wolfberry tree are already thin and weak, and the lack of nutrients leads to the insufficient absorption of nutrients in the flowers and fruits of the Chinese wolfberry tree, which will affect the fruit setting rate of the Chinese wolfberry tree, and because of the lack of nutrients in the branches and buds, the quantity and quality of the secondary fruit will also be reduced, seriously leading to economic benefits. These are the effects and symptoms of Chinese wolfberry trees when aphids occur.

Prevention and cure method

The influence of aphids on Chinese wolfberry trees is too great, so for the yield and quality of Chinese wolfberry trees, it is necessary to take control measures against aphids, which mainly have the following three points.

1. In fact, where Chinese wolfberry is planted, there are many natural enemies of aphids, such as aphid cocoon wasps, lacewings, ladybugs, flower bugs, etc., so we can protect the natural enemies of aphids and use them to control the number of aphids.

2. The disease and insect branches and fallen leaves trimmed in spring and autumn can be taken out of the orchard for destruction, and then the orchard can be cleaned again before the coming of spring next year, which can greatly reduce the number of aphid eggs.

3. In the period of aphid outbreak, artificial medicament hunting or artificial pruning of Lycium barbarum branches with a large number of aphids.
