Small Tiger

Scientific name Agrotis ypsilon Rottemberg Lepidoptera, Noctuidae. The term soilworm, silkworm, black soil silkworm, black silkworm. Host various vegetable and crop seedlings. Field recognition of larvae snaps off the stalks of the vegetable seedlings near the ground, killing the entire plant, causing ridges to become vacant and severely destructive. Morphological characteristics Adult body length 16-23 mm, wingspan 42-54 mm, dark brown, forewings divided into 3 segments by inner and outer transverse lines, with prominent nephrotic, annular, rod-like and Two black sword-shaped patterns; gray no hind tail markings. The egg is 0.5 mm long and is hemispherical. The surface has vertical and horizontal lines. The first milky white color appears, and the red markings appear after the hatching. The larvae are 37-47 mm long, grayish black, covered with variously sized particles on the surface of the body. The gluteal plate is yellow-brown and has two dark brown longitudinal bands. The beak is 18-23 mm long, auburn, shiny, and the engraved dots on the back of the 5th and 7th abdominal segment are larger than the engraved points on the lateral side. The hip spines are short-tipped. Occurrence of law occurs in algebra ranging from north to south, Heilongjiang 2nd generation, Beijing 3-4th generation, Jiangsu 5th generation, Fuzhou 6th generation. The overwintering state and location are still unknown in the north area. The extraction process is based on the concept of "congcong", "contemporary", "professional", "profuse", and "professional" (15).攴敝 Γ Γ Γ 拊 拊 拊 拊 拊 拊 拊 拊 3 沙 辜浠疃 辜浠疃 沙 沙 沙 沙 沙 沙 沙 沙 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 13 Flowers, oysters, lee, and salsas, etc., are spawned or piled, with an average of 800-1000 eggs per female. Adults have strong tropism towards black light and sweet and sour wine. A total of 6 instar larvae, before the age of 3 in the ground, weeds or host young parts of the feeding, the harm is not; 3 indurant lurking in the topsoil between the topsoil, out at night damage, agile, brutal and brutal white slaughter. The mature larvae have a dead-dead habit and are frightened into a ring. The larval development duration: 67 days at 15°C, 32 days at 20°C, and 18 days at 30°C. The developmental duration of crickets is 12-18 days, while the winter crickets are as long as 150 days. Small tigers prefer warm and humid conditions, with the optimal temperature range of 13-25°C. They can be found in rivers, lakes or low-lying areas, with adequate rainwater and perennial irrigation areas. Loams with loose soil texture, good grain structure, and strong water retention properties Clay loam and sandy loam are suitable for the occurrence of small tigers. Especially in the early spring vegetable fields and peripheral weeds, can provide spawning sites; honey source plants and more, can provide supplementary nutrition for adults, will form a larger source of insects, serious. Prevention Methods (1) Forecasting. The monitoring of adult worms can be carried out using black light or honeysuckers, which are set in the spring in North China from April 15 to May 20. If an average of more than 5-10 moths per day per day, the moths enter the moth During the period, the day with the highest number of moths is Fenglang, 20-25 days later is the peak period of 2-3 instar larvae, and it is suitable for prevention and control; if the moth trap is more than 30 consecutive days, the omen will have great occurrences. may. The larvae are measured by field survey methods. For example, there are 0.5-1 larvae per square meter before the fixed seedlings, or 0.1-0.3 larvae per square meter after the fixed seedlings (or 100 seedlings on the vegetable seedlings). 2) that should be controlled. (2) Agricultural control. Removal of vegetable fields and surrounding weeds in early spring to prevent oviposition of adult tigers is a key aspect. If they have been spawned and found 1-2 instar larvae, they should be sprayed before weeding to prevent the individual larvae from being buried. The weeds removed should be removed from the vegetable fields and treated with manure. (3) trapping and prevention. One is black light trapping adult worms. The second is the sweet and vinegar trap adult: 6 parts sugar, 3 parts vinegar, 1 part white wine, 10 parts water, 9 parts of trichlorfon and mix thoroughly, or add appropriate amount of pesticide with pickle water, set in the adult stage, both have trapping effect. Some fermented sour foods, such as sweet potatoes, carrots, rotten fruits, etc., are added to an appropriate amount of an agent, which can also entice adult insects. The third is bait trapping larvae (see 蝼蛄). The fourth is the trapping of larvae by the grass: before the planting of the seedlings, the tigers only feed on the weeds in the field, so they can choose to eat asparagus, prickly peas, if they sell vegetables, small spinach, hundred ji, AI In order to trap the larvae of earthworms, weeds, barnyard grass, imperata, and geese, etc. are piled up by humans, either manually or with chemicals. (4) Chemical control. The ground tiger is poorly resistant to 1-3 instar larvae and exposed to host plants or the ground. It is an appropriate period for chemical control. It can be used to kill crickets (21% synergistic cyanol emulsifiable concentrate) 8000 times, 2.5% deltamethrin or 20% fenflueretoin 3000 times, 20% chrysantha 3000 times, 10% bromoma Emulsion 2000 times, 90% trichlorfon 800 times or 50% phoxim 800 times.
