Integration and Application of Comprehensive Prevention and Control Technology for Sugarcane Borers in Low Latitude Plateau of China.

Aimed al the difficult problem of prevention and control of disastrous sugircane borers in low latitude plateau of China, this research systematically overcame the botlleneck of comprehensive prevention and control of sugarcane bores after 10 years of collaIborative research, and formed a number of core product technologies, which promoted the green and high-quality development of the sugarcane industry and achieved llie following innovative results. In this study, the species, population structure and damage characteristics of disastrous sugarcane borers in low latitude plateau were clarified for the first time, which provided a scientific basis for the formulation of technology and application of comprehensive prevention and control. The monitoring technology system and early warning monitoring network were constructed for the monitoring of borer pojHilation in low latitude plateau sugarcane area, wliich realized the accurate monitoring of the population dynamics of sugan-ane bores and provided technical support for comprehensive prevention and control, the flight spraying technology by unmanned aerial vehicle ( UAV) was developed for bores in the low latitude plateau cane area, and ii has been successfull) applied in a large area, therein opening up a new way of light, simple and efficienl for effeclive conlrol of borers. The scale application of lain]) trapping and sexual attracting to kill adult insects technology promoted the advancement of green control technology of bores. Integration was made to the comprehensive control techniques like UAV flight control, biological agents, physical and chemical inducement and control, and sexual attractant trapping in the low latitude plateau sugarcane area, and standardized technical regulations have been formulated, which significantly improved the overall prevention and control effect of large areas. The technologies for the comprehensive prevention and control of sugarcane Infers have been popularized and applied in 8 major sugarcane producing states (cities) in low altitude plateau of Yunnan over llie years, which has controlled the damage and showed remarkable control effect. In 2017 -2018, the integrated conlrol technology was popularized and applied to a total of 2.78x10⁵ hm2( 1.33x10⁴ hm² of LAV flight control) of area, which recovered a total of 3.666x10⁶ t of sugarcrane losses, increasing 4. 69 x 10 t of sugar with the sales increase of 3.979 billion yuan, added profits of 1.251 billion yuan and the taxes increase of 188 million yuan. The research results show that the technology has high technical integration, strong practicability, high degree of transformation, significant economic:, sexual and ecological benefits, which provide technical supports for the sustainable development, loss reduction and efficiency increase of the sugarcane industry in the low-latitude plateau sugarcane region, and make significant contributions to the economic development of ethnic minorities in the border-stricken areas and the increase of farmers" income and poverty alleviation.
