There are many kinds of pests that harm the pomegranate. There are more than 200 species in China. The following are common:
The Japanese wax worm, commonly known as the scale insect, is a member of the order Homoptera and Cerambycidae. It attracts sap from the leaves or shoots of the nymphs, secretes mucus, induces coal pollution, affects photosynthesis, weakens the tree vigor, and causes large numbers of fallen leaves. , fruit drop, in severe cases, can cause dead or even the whole tree withered.
Control methods: (1) Chemical control. From the hatching of the nymphs to the formation of the wax shell, it is an advantageous opportunity to control the chemicals; in production, it can be used in the nymph incubation period with 25% imidophos 800-1000 times solution, 50% malathion 1000-1500 times solution, 50 % Cevavidin WP 400 to 500 times or 50% dichlorvos EC 800 to 1000 times, spray every 7 to 10 days, and spray 2 to 3 times, you can control the damage. (2) Protect and use natural enemies. There are many kinds of natural enemies in Japan, such as ladybugs, grasshoppers and parasitic bees.
Leopard wood moth moth is also called coffee moth moth, cotton stem moth moth, is a phosphorus moth, wood moth family. The larvae feed on the pomegranate trunks and branches, causing the branches above the victim to yellow, die or break; the affected branches cannot be normal, even if the results cannot grow and mature.
Control methods: (1) Light trapping. The leopard moth adult moth has phototaxis and can install black light traps in the pomegranate garden. (2) Chemical control. After the larvae have infiltrated, see the emergence of fresh worms, use dichlorvos EC 10 times to inject into the holes, and then block the holes with mud.
Pomegranate Striata moth, also known as flower window moth, occurs in most of the pomegranate-producing areas in China. It damages shoots and perennial shoots with larvae, making the tree vigor debilitating, affecting fruit yield and quality. In severe cases, it can cause whole plant death. .
Control methods: (1) In the pomegranate growing season, the branches are often inspected, and the damaged shoots are found. The shoots are cut off from the lower end of the last defecation hole in time to eliminate the larvae. (2) Chemical control. In the hatching period, the use of enemies mixture 1000 times, 1000 times dichlorvos emulsion or 2.5% enemy killed 3000 times spray control, the effect is good. After the larvae break into the shoots, 400 to 500 times of dichlorvos can be injected into the insect canal by using waste syringes or other tools, or the cotton balls can be used to dip the dichlorvos solution into the boreholes, seal the yellow mud, and kill the larvae.
The peach aphid, also known as peach aphid, peach aphid, and peach aphid, is a species of the order Phosoptera, Saccharidae, and is eaten by larvae feeding into the fruit. There are often several larvae in one fruit, and the victim is full of insects. Dung can easily cause fruit cracking and rot, seriously affecting quality and yield.
Control methods: (1) fruit bagging. After the pomegranate grows to the size of the thumb of the fruit and the second natural drop of fruit, bagging is performed to prevent the codling moth from spawning on the fruit surface. (2) Chemical control. In the period of adult emergence and spawning, spraying with 50% killer pine or 50% phoxim EC 1000 times, 50% phoxim EC or 90% crystal trichlorfon, add fine soil 100 parts, made of pharmacy, blocking the carcass, the effect is good.
Peach small carnivorous insect commonly known as "Peach small", is a kind of Pygoptera, Pyralidae, is the main pest of the pomegranate fruit. Adults lay eggs on the pomegranate fruit surface, one for each fruit. The larvae hatch into the fruit after hatching and the pods are small. After the larvae dig into the fruit, the larvae feed on the fruit or subcutaneously and the worms remain in the fruit.
Control methods: (1) In the larval excavation period (June-July), use a 300-fold solution of 50% phoxim EC to spray on the ground below the canopy and spray the tree tray after spraying. (2) In adulthood, spray 2.5% enemies or 20% cypermethrin 3000 times to kill eggs and newly hatched larvae. (3) Found bug fruit, timely removal and buried or burned.
