Comprehensive bactrocera cucurbitae prevention and control method

Abstract

The invention discloses a comprehensive bactrocera cucurbitae prevention and control method. The comprehensive bactrocera cucurbitae prevention and control method comprises the specific steps that 1, a pesticide is sprayed, wherein 320-400 times of efficient cyhalothrin and high lipid membrane powder liquid with the concentration of 26-32 mg / L is sprayed to melon and fruit flowers in a melon and fruit flowering phase; 2, bagging protection is performed, wherein fruits undergo bagging protection within 1-3 days after the melon and fruit flowers fall. According to the method, efficient cyhalothrin and high lipid membrane powder are mixed in use and play a synergistic effect, the usage amount of the efficient cyhalothrin is decreased, the lasting period of the efficient cyhalothrin is prolonged, the bactrocera cucurbitae preventing and control effect is up to 92% or above, and the fruit yield and quality are remarkably improved.

Description

technical field [0001] The invention relates to the field of pest protection, in particular to a comprehensive control method for the fruit fly. Background technique [0002] Melon fruit fly is one of the world's quarantine pests, and its host plants have exceeded 125 species, and the degree of loss of melons and fruits after damage is generally between 30% and 100%. Due to its unique climate and geographical environment, Guangxi has become the main producing area of ​​fruits and vegetables. At present, Guangxi grows bitter gourd, muskmelon, watermelon, cucumber and zucchini and other Cucurbitaceae plants, and is one of the hardest-hit areas for the fruit fly. In Longshan County, Guangxi, the damage rate of fruit flies to melons and fruits reached 19-35.6%. In Wuming County, the damage rate of fruit flies to loofahs reached 25-47%. The damage rate of Bacteria melons to bitter gourd is 12.7%. Chemical control is an important control measure in the hardest-hit areas of melo...

Problems solved by technology

However, the mature larvae of the fruit fly often pupate in the soil below 0.5-15cm. It is difficult to control the population of the fruit fly by simply relying on chemical control, and the fruit fly can complete 80% of the oviposition requirements in one mating, which will affect the population of the next generation. Weak influence

Most of the melons and fruits infested by the melon fly have a long growth cycle and are continuous flowering plants. The field bagging operation is difficult and consumes manpower and material resources. In actual agricultural production, only precious melon and fruit varieties are bagged.
