First, the main types of grasshoppers. Grasshopper, Licao, Chinese grasshopper and so on. 1. Host: Apple Astragalus, Apple Blast, Pyrus Bacteria, Pyriacidae, Pear, Peach, Peach Blast, Wheat Bran, Vegetable Bran, Corn Bran, Sorghum, Cardamom, Willow Cotton Oh, wait. They also prey on red spiders and their eggs; they can also feed on the eggs of the cotton bollworm, various moths, and bridges; the small larvae and leaf curlers of the bollworm, and the scale insects such as pine maggots and their eggs. 2. Habitat habits of big grasshoppers: 4 generations occurred in 1 year, and they lived in the midst of winter. A large number of eclosion occurred in the middle and late April, and adults occurred from June to October. There was a clear overlap between generations. In summer and autumn, each of the worms has an egg period of 3-12 days, a larval period of 8-31 days, a flood period of 9-28 days, an early spawning period of 11-18 days, and a generation period of 31-53 days. Each female lays an average of 780 eggs. Adults can be active both during the day and in the evening, and summer activities are more productive at 6-9 and 17-20. Adults have phototaxis. Adult spawning often occurs in more than 10 to dozens of grains in one place. Eggs hatch from green to gray to gray. Eggs are darkened 2-3 days after being parasitized by parasitoids. After 0.5-2 hours of egg hatching, the larvae climbed down the egg handle and began looking for food. Larvae and adults prey on various aphids and also prey on other pests. 1 larvae 1 generation predated 600-700 locusts. Adults were able to prey on 500 heads, and they could eliminate 1000-1200 locusts in their lifetime. After the larvae are mature, they become cicadas in the vicinity of the dorsal veins or other folds. From late September to mid-November, the pods are gradually overwintering, mostly in bark joints, tree burrows, branch wounds, and litters. Distribution of provinces and regions across the country. 3. Life habits of Lithocalyx: overwintering in the winter, 4-5 generations occurred in 1 year. Due to the long life span of the adult and the long spawning period, there are overlaps between generations. In late April, overwintering pupa began to emerge, and adults were born from May to May. Eggs are scattered. In summer and autumn, the worming periods are as follows: egg period 3-5 days, larval period 9-18 days, flood season 10-14 days, spawning period 5-9 days, and generation period 27-43 days. Each female lays an average of 630 eggs. Adults also have phototaxis, black light and fluorescent lamps can trap a large number of adults. Larvae and adults prey on locusts, red spiders, etc. Its food intake is similar to that of large grasshoppers. Distribution with large grasshoppers. 4. Living habits of Chinese grasshoppers: Overwintering of adult grasshoppers occurs in 4-5 generations in one year, and overwintering adults emerge from late March to early April. Spawning starts from mid-late April to early May, and eggs are scattered. Adults of the first generation occurred in July and adults occurred from August to November. Each female lays an average of 488 eggs. The duration varies from generation to generation. The average temperature is 13-19°C, and the generation period is 64 days; at 21-22°C, the duration is 30 days; at 27-28°C, the duration is 24 days. The egg period is 3-12 days, the larval period is 8-27 days, the pupa period is 8-17 days, and the pre-spawning period is 4-8 days. Larvae and adults prey on aphids and red spiders. Distributed throughout our country. 5, the use of ways: (1) protection over the winter. If overwintering earthworms are found on the tree's holes, stone seams, and fallen leaves, they can be collected, protected in the natural enemy's feather cages, placed in a cool room, cooled and then placed in an outdoor cool place, and immediately after the emergence of adult insects in April, Released in the orchard. (2) In the mid-to-late April, the adult emergence period, orchards should not be sprayed with contact insecticides, and other time should be used less. (3) Induction of insects using fluorescent or black light lamps, moved to orchards. (4) Artificial rearing with aphids or rice moth eggs, etc., and removing eggs, larvae or pupa from the orchard. If not used for a while, the larvae can be gradually cooled feeding, generally can be reduced to 12-15 °C, wait until the knot phlegm, can be refrigerated in a 5-6 °C refrigerator. 3-4 months, the survival rate can reach more than 75%. Second, the main species of Syrphidae are black-skinned fly flies, narrow-banded flyworms, moon-spotted flyhead flyheads, tick-flyheaded flyheads, six-legged flyworms, and thin-spotted flyworms. 1. Host: apple astragalus, apple tumor aphid, pear bifurcation, pear powder aphid, pear round aphid, peach aphid, peach aphid, vegetable aphid, corn aphid, wheat aphid and other aphids. 2. Habitat life habits of black tapeworms: Occurrence of 4-5 generations in 1 year and wintering with mature larvae, cockroaches or adults. Adults can be seen from April to December. Adult insects soar in the air, often vibrating their wings and keeping them in place. It spawns little in the locust population. In summer, the egg period is 2-3 days, and the larval period and pupa period are 6-7 days. Adults eat nectar, larvae prey on locusts, grasp locusts with mouthparts, lift up in the air, suck up body fluids, and discard maggot corpses. The average larvae of all ages can prey on 120 locusts per day, and 700-1500 locusts can be preyed on each head during the entire larval period. After the larvae are matured, the larvae are defoliated in the leaves caused by the damage of the leaves or locusts. When there are no locusts on fruit trees or trees in autumn, they often fly to wheat fields, vegetable gardens, or herbaceous plants on forests to prey on grasshoppers. Later, they enter the soil and peat on the surface to overwinter. This type of fly is very common, and it is distributed in Heilongjiang from the north, Guangxi, Yunnan, and Tibet in the south. 3, narrow-belly tapeworm living habits: 4-5 generations occurred in 1 year, with pupa or adults overwintering. In the first half of June, the first generation of adults occurred. From July to October, there were adult animals. This fly larvae prey on locusts. Domestically distributed from south to north. 4, the use of ways. (1) No spraying or no spraying of contact insecticides. Aphids and pupa are 200:1. (2) Overwintering larvae or earthworms can be collected from vegetable gardens in early spring and early March. They are stored in cool indoor areas and placed into orchards when the adults emerge. If necessary, it can be refrigerated in a refrigerator at 5-7°C. The soil in the cold storage should not be too dry. When it is needed, it should be taken out at room temperature and be feathered, or directly placed in the orchard. (3) There are planned arrangements for orchards, forest belts, grain fields, and vegetable gardens, so that the flies can have opportunities for migration and reproduction.
