Wheat red worm is a devastating pest of wheat, belonging to the family Diptera. In 2001, in the towns of Changgou, Nanzhang, Anju and other towns, the area of ​​damage was 120,000 mu, generally reducing production by 30% to 50%, severely reducing production by more than 80%, and even producing. In the prevention and control of wheat red-sucking worms, it is necessary to adopt an integrated prevention and control method based on agricultural control and supplemented by chemical control. 1 selection of insect resistant varieties The production should use wheat varieties with long thorns, tight mouths, dense spikelets, short and concentrated flowering period, and thick peels, such as Jining No.13 and Jimai 19, etc., for spawning and larval invasion of wheat red-sucking worms. It is unfavorable to reduce the damage of wheat. 2 deep turn, turn for change The production practice proves that the wheat fields are turned over in a row, and the crops of wheat, beans and cotton are cropped, which has a significant effect on the number of insects. 3 chemical control 3.1 When the soil is applied in autumn, it should be combined with deep turning. Use 6% lindane powder 2.0-2.5kg per acre or 2.5-3.0kg 5% methyl isoflavone granules. Mix 20~30kg of fine sand with sprinkle, then fine Can significantly reduce the number of wintering insects. 3.2 The prevention and control of flood season is to control the emergence of adult insects. In the wheat booting stage, 1.5% 1605 powder 2.5-3.0kg or 40% methyl isoflavone emulsifiable concentrate 150-200g or 6% lindane powder 1.5-2.0kg per acre, mixed with fine sand The ridge is applied and then slashed or watered. 3.3 Prevention and control of adult insects In the early stage of wheat heading to flowering, use 25% quick killing emulsifiable concentrate 30-40g or 25% octane cyanide emulsifiable oil 40~50g or 20% bismuth emulsifiable concentrate 40~50g, spray 50~60kg on water After spraying for 4 to 5 days, the control effect is more ideal.
