Recently, a survey conducted by technicians in Jixian County, Hebei Province, found that the occurrence of serious tigers in spring corn field reminded farmers to take precautions. The ground larvae are the most harmful to larvae, and the life and harmful habits of different age larvae are different. 1st and 2nd instar larvae stay up late at night and feed on the leaves or young leaves; they hide in the soil during the daytime after 3rd instar, which damages the young shoots at the base of the seedlings and causes the lack of seedlings; 4th instar larvae are harmful and resistant to insects. Medicinal properties are also greatly enhanced. Therefore, chemical control should eliminate larvae before 3rd instar. The prevention and control of the ground tiger must be combined with measures such as moth trapping, weeding, pharmacy, and artificial control to effectively control the damage. Trapping and killing adults and trapping and killing adult worms are the best strategies for controlling the ground tigers, which can greatly reduce the number of first-generation larvae. The method is to use black light and sweet and sour liquid to kill. Eradication of weeds and weeds are the breeding grounds of tigers. Weeds can be removed immediately in the ground, on the edge of the ground, and on the roadsides of the fields, and taken out of the field in time for fertilizer or fertilizer to destroy some eggs or larvae. Spray control, in the evening, use 2.5% deltamethrin EC 2000 times solution or 4.5 days Longbao beta-cypermethrin EC 3500-4000 times solution or 50% phoxim EC 1000 times solution (to strictly control the dosage) spray. Sprinkle poisonous soil and poisonous sand, use 50% phoxim 0.5 kg of water and appropriate amount of water, spray and mix 100 kg of fine soil, or use 1 part of 20% cypermethrin emulsifiable concentrate to mix 2,000 parts of fine sand in the field. Bait trapping and killing of larvae with more than 4 instars are better. 0.5 kg of 90% trichlorfon is opened with hot water, add about 5 liters of clear water, spray on sauteed oil dregs (it can also be replaced with cottonseed skin). Use 4 to 5 kg of bait per acre and spread it in the evening. Irrigation may be used to irrigate the roots. When the worm age is relatively large, 80% dichlorvos EC or 50% phoxim should be used. 0.2 kg per mu should be used to irrigate 400 kg of water per root, or be applied to plant stems for control. Manual capture, for the damage to the heavier plots, when the field appears broken seedlings, early in the morning can be dialed off the topsoil near the seedlings or wheat straw, killing old larvae.
