There are more kinds of pests that harm pomegranate. There are more than 200 species in China, and there are mainly seven species (classes).
First, the Japanese turtle wax. Commonly known as scale insect, belonging to the order of the genus Homoptera, wax mites, nymphs fixed on the leaves or new shoots to suck juice, and secrete mucus, induce coal pollution, affect photosynthesis, weaken the tree, cause a lot of defoliation, fruit drop, serious It can lead to production or even the whole tree.
Control methods: (1) chemical control. The nymph is a favorable time for chemical control before hatching. Before production, it can be used in the nymph hatching period, using 25% imipenem 800-1000 times solution, 50% malathion 1000-1500 times solution, 50 % carbaryl wettable powder 400-500 times liquid or 50% dichlorvos emulsifiable oil 800-1000 times liquid, spray once every 7-10 days, even spray 2-3 times, you can control it. (2) Protect the use of natural enemies. Japanese turtles have many natural enemies, such as ladybugs, grasshoppers, parasitic wasps, etc., should pay attention to protection and utilization.
Second, the leopard-printed wood moth. Also known as the coffee scorpion moth, cotton stalk scorpion moth, is a Phosphorus, scorpion moth family. The larvae feed on the trunk and branches of the pomegranate, causing the branches above the victim to yellow, dead or break; the damaged branches can not produce normal results, even if the results can not grow and mature.
Control methods: (1) light trapping. Adults of the Leopard Python moth are phototaxis, and black light can be installed in the pomegranate garden to trap adults. (2) Chemical control. Before the larvae invade, spray with 50% monocrotophos 1500 times, or when fresh worms are discharged after the larvae are invaded, inject 10 times with dichlorvos emulsifiable concentrate, and then block the holes with mud.
Third, the pomegranate stem window moth. It is also called flower window moth, which occurs in most pomegranate producing areas in China. The larvae are used to damage new shoots and perennial branches, which makes the tree weak and affects the yield and quality of the fruit. In severe cases, the whole plant can die.
Control methods: (1) During the pomegranate growing season, the branches are often inspected and the new shoots are found. The branches are cut off from the lower end of the last drain hole to eliminate the larvae. (2) Chemical control. In the incubation period, the effect is good with 1000 times of enemy horse mixture, 1000 times of dichlorvos emulsifiable concentrate or 2.5% of enemy killing 3000 times. After the larva breaks into the branches, a 400-500 times solution of dichlorvos can be injected into the insect channel with a tool such as a waste syringe, or a cotton ball and dichlorvos can be inserted into the pupil, the yellow mud is sealed, and the larvae are smoked.
Fourth, peach aphid. Also known as the peach aphid, the peach spot, the peach spot, the genus Phophenidae, the genus Corydalis, larvae into the fruit for feeding, a fruit often contains several larvae, the victim fruit is filled with worms, pole It is easy to cause cracking and rot, which seriously affects 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 fruit drop, the bag is placed to prevent the moth from laying eggs on the fruit surface. (2) Chemical control. In the adult stage and the spawning period, spray with 50% chlorpyrifos or 50% phoxim emulsifiable concentrate 1000 times, or use 50% phoxim emulsifiable concentrate or 90% crystalline trichlorfon, add fine soil. 100 parts, made into a mud, blocked the tube, the effect is good.
Five, yellow thorn moth. Commonly known as "itch itch", it belongs to the order Phosphoptera, the genus Moth, and the larvae bite the leaves. The young larvae only eat mesophyll, leave the veins, and eat the leaves into a network; the older larvae can eat the leaves as nicks, leaving only the petiole and main veins in severe cases, and the whole branches or even the whole leaves can be eaten when the amount is large.
Control method: When the larva is found to be harmful, it should be sprayed with 50% phoxim emulsifiable concentrate 1000-1500 times liquid, 50% chlorpyrifos EC 1000-1200 times liquid or 50% long-acting phosphorus emulsifiable oil 1000-1500 times. In addition, pay attention to the protection and utilization of natural enemies.
Six, pomegranate towel night moth. It belongs to the order of Phosphoptera, Noctuidae, and the larvae feed on the leaves. It is a common leaf-eating pest on pomegranates. The first and second quarters of the larvae of the larvae are often curved and bridged, which is easy to mix with the bridge-building insects (the larvae of the genus Mothaceae); the body color is very close to the new branch of the pomegranate, which is difficult to be found, but can be based on the leaves that are eaten into nicks. Find the larva along the branches.
Control method: potted pomegranate can be artificially captured; when the amount of larvae is large, 20% of pyrethroid 2500 times solution, 20% of chlorpyrifos 3000 times solution, 80% of dichlorvos emulsifiable concentrate 1000 times solution or 90% crystal trichlorfon can be used. 1000 times liquid spray.
Seven, peach small heartworm. Commonly known as "Peach Small", it belongs to the Phophenidae, the fruit moth family, which is the main pest of the pomegranate fruit. Adults lay eggs on the surface of pomegranate fruit, one fruit per fruit. The larvae hatch into the fruit after hatching, and the pupil is small. After the larva breaks into the fruit, the grain is taken toward the heart or under the skin, and the worm feces remain in the fruit.
Control methods: (1) In the period of larvae unearthing (June-July), spray the ground under the canopy with 50% phoxim emulsifiable concentrate 300 times, and spray the shallow eucalyptus tray. (2) In the adult period, spray 2.5% enemy kill or 20% pyrethroid 3000 times solution to kill eggs and newly hatched larvae. (3) Found the insect fruit, promptly removed and buried or burned.
