Guangxi: Red-eyed bees have a good effect in preventing sugar cane worms

Sugarcane aphids are the main pests in sugarcane production.
statistics, Guangxi due to the harm of sugar cane worm caused annual sugar cane production reduction of 10%-20%, more than 30% in severe cases.
the traditional means of preventing and controling sugar cane worms is the spraying of chemical pesticides, the long-term use not only enhances the resistance of pests, but also kills natural enemies and worsens the ecological environment of sugar cane fields.
years, Guangxi Zhuang Autonomous Region has actively promoted the technology of red-eyed bee control of sugar cane worm, effectively reducing the use of chemical pesticides, and achieved good economic and social benefits.
to implement special funds.
2018, the project promotion demonstration has been carried out for 3 consecutive years in the main sugar cane producing counties such as Xixiangtang District of Nanning City, Xingbin District of Guest City and Fuxian County of Chongzo City.
Autonomous Region financial arrangements for special subsidy funds of 3 million yuan per year, a cumulative arrangement of 9 million yuan, mainly used for pest monitoring and early warning system (equipment), red-eye bee cards and other technical materialized input production or acquisition, technical training, publicity and promotion, effect assessment, project acceptance and employment of labor and other labor costs.
implement the main system sugar enterprises in accordance with the standard of not less than 1:1 to raise matching funds, three years to raise a total of 13.24 million yuan supporting funds.
strengthen the regulatory management.
Guangxi Zhuang Autonomous Region Sugar Industry Development Office every year to develop the "use of red-eyed bees to control sugar cane aphid demonstration project implementation program", requiring sugar enterprises as the main body, through the implementation of the use of red-eyed bees to control sugar cane aphid demonstration projects, radiation led to the main production areas to promote the application of pest green control technology, and constantly improve sugar cane production and quality, increase the supply of high-quality green products.
each demonstration area of not less than 30,000 mu, built a sugar cane pest monitoring and early warning system, the demonstration area within the range of sugar cane farmers and sugar factory farmers to be released in a timely manner according to the peak period.
innovative promotion model.
, Guangxi explores and summarizes a set of "sugar industry authorities, sugar enterprises, specialized prevention and control companies, sugar cane farmers" innovative promotion model.
department in charge of sugar industry in the county is mainly responsible for supervision and management, formulate specific implementation plans, determine the project demonstration area site selection, technical routes, service models, acceptance summary.
sugar enterprises to carry out the promotion and application of beekeeping technology, including the organization of the prevalence of aphids, pest characteristics of investigation and pest monitoring, technical publicity and training, to determine the time to release bees and carry out field bee release work, to carry out effect tracking survey.
Specialized prevention and control companies in the process of providing full service to sugar enterprises rely on the platform advantages, the project demonstration area cane farmers to achieve green prevention and control of new technology unified training, unified implementation, unified prevention and control, unified standards, so that the vast number of sugar cane farmers really feel the green prevention and control of new technology brought about by the increase in production and increase sugar efficiency, driving the vast number of sugar cane farmers independently choose to use the green prevention and control of new technologies.
a wide range of training demonstrations. the
demonstration area mainly takes the form of video playback of thematic bee-releasing technology, distribution of publicity materials, on-site explanation by technical personnel, etc., to strengthen the understanding and understanding of pest and disease investigation methods between agricultural personnel, sugarcane farmers and beekeepers, and to improve the technical level of the use of red-eyed bees to control sugar cane aphids.
statistics, from 2018 to 2020, the demonstration area produced and broadcast a total of 735 special videos, distributed 8,600 copies of promotional materials, carried out 70 live field demonstrations, and trained more than 2,500 people.
implementation has been remarkable.
2018, the region has promoted the application of red-eyed bees to control sugar cane worm demonstration area of 290,000 mu, accounting for 2.57 percent of the sugar cane cultivation area in Guangxi, achieved remarkable results.
After comprehensive assessment, the average rate of sugar cane cocoon damage in the demonstration area was 26.5%, which was 31.06 percentage points lower than that of chemical control, the average rate of cocooning was 2.31%, a decrease of 6.39 percentage points, and the average rate of broken tail (broken stem) was 2.21%, a decrease of 2.88 percentage points.
the average yield of sugar cane in the demonstration area was 5.91 tons/acre, an increase of 0.92 tons/acre, and the average theoretical sugar content was 16.41%, an increase of 0.96 percentage points.
0.5 kg/acre of pesticide use in conventional chemical control areas, the demonstration area basically does not use chemical pesticides, the control is obvious.
60 yuan per mu of sugar cane farmers, the average yield of 456 yuan per mu, input and output ratio of 1:7.6.
the relevant person in charge of the sugar industry development office of Guangxi Zhuang Autonomous Region said that the application of red-eyed bees to control sugar cane aphids is the implementation of the autonomous region "pesticide zero growth action" specific measures.
Next, the Office of Sugar Industry Development of the Autonomous Region will further increase the intensity of demonstration and promotion, strengthen the promotion and training of green sugarcane production, and continuously improve the enthusiasm and initiative of sugar-making enterprises and sugarcane farmers in the application of red-eyed bee control sugar cane worm technology, and accelerate the popularization and popularization of green prevention and control technology in sugarcane production.
