1. The life of rice is divided into: the paddy field, the pre-field period, the tiller jointing stage, the heading stage and the filling stage.
2. Common pests on rice include: stem borer, stem borer, rice leaf roller, rice planthopper.
3. The diseases that often occur on rice are: rice blast, rice stripe disease, rice false smut, rice sheath blight.
4. Rice stem borer and stem borer are commonly known as: heartworm.
5. Rice rice leaf roller is commonly known as: leaf curler.
6. Rice koji disease is commonly known as: Ash.
7. The diseases of the stem borer and the stem borer are: larvae drilled rice stems, causing dead seedlings at the seedling stage and tillering stage; invading at the early stage of booting, causing dead ears, invading at the end of the booting stage and early stage of heading, biting Broken spike neck, causing white spikes or insect strains.
8. The newly hatched larvae of the stem borer will also feed on the leaf sheath to cause a sheath.
9. Rice is most susceptible to secondary and tertiary mites: tillering and booting.
10. Rice leaf roller is a migratory pest. It is a local occurrence, intermittent damage, and has become a frequent pest.
11. The rice leaf larvae larvae harm rice, and the leaves are longitudinally licked. The mesophyll is eaten in the sorghum, leaving the leaves of the leaves as white strips, which affects photosynthesis of rice plants.
The larvae of the rice leaf roller are 6 years old. At the age of 1st, it is not scarred but hidden in the heart of the rice; 2 years old at the tip of the tip of the 1-2 cm small scorpion; after 3 years of age, the knot is long, and even a few leaves are scarred.
In the prevention and control of rice leaf roller, the field is generally controlled about 3 times: the tillering period is 1 time, and the earing stage is 2 times.
The rice planthoppers that occur on rice are divided into: gray planthopper, white-backed planthopper, and brown planthopper.
15. The main cluster of rice planthoppers feeds on the lower part of the rice plant, and sucks into the rice plant tissue to suck juice with a sucking mouth. When the amount of insects is large, the lower part of the rice plant becomes black and squats, which is commonly called “topping, and through the skyâ€, resulting in severe production loss or loss.
The agent for controlling rice planthopper can simultaneously control rice leafhoppers and rice thrips.
Rice blast can occur in the whole growth period of rice, which is a diseased seedling, called nursery, and the leaf is called leaf mites, and the ear is called stalk, which is called thrift.
18. Rice stripe disease is a new and rising disease. The gray planthopper spreads the virus. The farmers do not see the symptoms of the disease and will not take the initiative to prevent and control. It is easy to miss the opportunity of prevention, which will lead to the infection in the early stage. death.
The prevention and control strategy is to “cut off the source of the poison and control the disease and control the diseaseâ€. The key is to cure the Datian in the field and the late period of the pre-treatment period.

27. Plutella xylostella is one of the most common and serious pests in cruciferous vegetables in China.
28. The first instar larvae of Plutella xylostella only feed on the mesophyll, leaving the epidermis, forming a transparent plaque on the leaves of the cabbage, that is, “opening the skylightâ€; the 3-4th instar larvae can eat the leaves and nicks, and the whole leaves in severe cases. Was eaten into a mesh.
29. Plutella xylostella is in the north, and it has two peaks in May-June and August (a large-scale cultivation season of cruciferous vegetables), which is harmful in spring. The Yangtze River Basin and southern China provinces are March-June and 8-11. The month is two peak periods, and the autumn is heavier than spring.
30. The newly hatched larvae of Spodoptera litura stalked and fed. Before the third instar, only the mesophyll was left, and the epidermis and veins remained. It turned white and turned yellow, which was easy to identify. After entering the gluttony period after 4 years of age, most of them came out in the evening.
31. The obvious characteristics of beet armyworm larvae are: The abdominal valve line is a distinct yellow-white longitudinal band.
32. The newly hatched larvae of the beet armyworm are clustered on the back of the leaves, and they are sprinkled with nets, and the mesophyll is eaten inside, leaving the epidermis. The 3rd instar larvae are clustered, and they are nocturnal and have a false death.
33. The mature larvae of Spodoptera litura and Spodoptera exigua generally lick in the soil.
34. On cabbage, cabbage caterpillars can also cause soft rot of cabbage.
35. Pieris rapae occurs mainly on cruciferous vegetables.
36. The adult leaf of the jumping armor is the most serious in the seedling stage. The larva only harms the roots of the vegetables, causing the leaves to die.

42. Citrus rusted spiders will produce: black fruit.
Lychee mites are important pests in the production of litchi.
44. The larvae of the locust mites dig the core of the fruit during the expansion period of the fruit, resulting in fruit drop; after the color of the husk is hard, the stalk is only eaten, and the worm is left in the pedicle, which affects the quality.
45. The hatching of the larvae of the locust mites directly into the nucleus from the bottom of the egg shell, and there is no turning habit until the old cultivar is removed. Therefore, the key to controlling the locusts is the adult before spawning.
46. ​​In addition to larvae sucking fruit tree juice, lychee can also emit odor liquid on young leaves, flower spikes and fruits, making this part brown burned.
47. The most similar feature of cockroach (Litchi 棉, cotton blind 绿, è½, etc.) and locusts and white mites is that they are all sucking mouthparts pests.
48. Chlorpyrifos is mainly caused by phytotoxicity on tobacco, and it inhibits growth when the seedling stage has a high humidity and temperature.
49. Wheat rust is commonly known as rust caused by Huang Heng disease, including stripe rust, leaf rust and rod rust.
50. Common root diseases on cotton are: cotton wilt and cotton verticillium.
51. The body of an insect is divided into: head, chest, and abdomen.
52. The insect's chest is born with two pairs of wings and three pairs of feet, which are the center of movement.
53. The head of the insect is born with a pair of antennae, a pair of compound eyes, 0-3 single eyes and a mouthpiece, thus being the center of feeling and feeding.
54. The main types of insect mouthparts are chewing mouthpieces, sucker mouthpieces and siphon mouthpieces, while chewing mouthparts are the most primitive and typical mouthpieces.
55. The source of the pesticide, the pesticide can be divided into: inorganic pesticides, botanical pesticides, microbial pesticides and organic synthetic pesticides.
56. Pesticides are classified according to different control objects: insecticides , fungicides, herbicides , acaricides, nematicides, rodenticides and plant growth regulators.
