| titleOfInvention | Method for preventing and treating brown planthopper by utilizing red-colored lygus lucorum |
| abstract | The invention discloses a method for preventing and treating brown planthopper by utilizing red-colored lygus lucorum, which comprises the following steps: step one, sampling brown planthoppers in the target rice field by using a five-point sampling method and identifying the insect ages of the brown planthoppers; step two; counting the population density of 2-3 instar brown planthoppers in the target rice field by using an investigation sampling method; step three, implementing prevention and control work: draining accumulated water in the target rice field, and then releasing 4-year nymphs and 5-year nymphs of the red color lygus lucorum in a single time, wherein the number ratio of the 4-year nymphs and the 5-year nymphs of the red color lygus lucorum to the 2-3-year brown planthopper is 2: 1.5-2: 60. The invention reduces the using amount of chemical pesticides on rice, reduces pesticide residues in rice fields, protects the ecological environment of the farmland and provides reliable technical guarantee for grain safety. |
