Embodiment

[0088] A kind of integrated method of ecological control cotton bollworm of the present invention, carry out according to the following steps:

[0089] a. According to the law of occurrence of cotton bollworm, first combine with winter irrigation to eliminate overwintering pupae before winter, the pupae of cotton bollworm are mostly in the ground ridge, remove the pupae by shoveling the ridge, destroy its pupa chamber, and reduce its overwintering base;

[0090] b. Plant corn trapping belts according to the size of the plot in the cotton field. After the peak oviposition period of the second generation of cotton bollworms, cut off the trapping belts or spray them to kill some cotton bollworms;

[0091] c. Adults of the overwintering generation of cotton bollworms mainly lay eggs in the wheat fields. From the beginning of May, sexual attractants are deployed in large areas in the wheat fields to trap or fascinate the adults of the overwintering generations, reducing the base of ...

Abstract

An integrated method for ecologically preventing and eliminating ballworm features the integration of the winter irrigation for eliminating its overwintering pupae, planting corn zone as attraction zone after the cotton is sown, applying sexual attractant in large area for capturing them, use of trichogramma as the natural enemy of ballworm, and applying low-poison efficient agricultural chemical.

Description

technical field [0001] The invention relates to an integrated method for ecological control of cotton bollworm. Background technique [0002] Cotton bollworm is distributed in domestic and foreign cotton regions, and is an important pest of cotton in the bud stage. Since 1992, there have been major outbreaks in the Huanghuai Haimian area and the Yanjiang cotton area, causing huge economic losses, and the cotton planting area has dropped significantly. For decades, the control of cotton bollworm has mainly relied on chemical pesticides, resulting in a series of serious economic and ecological problems. Biological control is mostly based on a single technology, such as only using sex attractant, virus insecticide or Trichogramma, the control effect is not good, which affects the application of biological control technology. Since the serious outbreak of cotton bollworm in the reclamation area in 1995, the occurrence area has gradually expanded, and the...
