Prevention and treatment method for bactrocera dorsalis

Abstract

The invention discloses a prevention and treatment method for bactrocera dorsalis. The method comprises the following steps: preparing an attractant and a trapping adhesive, and designing a fruit-shaped trapper by using a yellow-green plate with a virtual wavelength of 530-550 nanometers; coating the surface of the trapper with the trapping adhesive, and throwing the attractant into the trapper through a hole; hanging the trapper filled with the attractant on a fruit tree for trapping operation; and strengthening cultivation management in an orchard. According to the method disclosed by the invention, bactrocera dorsalis is trapped by utilizing the attractant and plant trapping components in the trapping adhesive; plant components such as guava fruit volatile matters and banana puree areapplied to prevention and control of bactrocera dorsalis, so the harm of bactrocera dorsalis can be reduced, the yield and quality of fruit can be improved, and pollution to the environment can be reduced; and the fruit-shaped trapper is designed by using the yellow-green plate with the virtual wavelength of 530-550 nanometers, so bactrocera dorsalis can be visually attracted, and trapping effectcan be improved.

Description

technical field [0001] The invention relates to the technical field of prevention and control of diseases and insect pests, in particular to a method for preventing and controlling Bactrocera dorsalis. Background technique [0002] Bactrocera dorsalis Hendel is an important pest in tropical and subtropical regions. It belongs to Diptera, Tephritidae, and Oligochrichtes subfamily. It is commonly known as fruit maggot, also known as golden fly and oriental fruit fly. Bactrocera dorsalis was first discovered in tropical and subtropical regions of Asia. my country is an invasive species. According to records, it was first discovered in Taiwan, China in 1911, and it was recorded in mainland China in 1937. At present, this insect has become one of the most harmful fruit and vegetable pests in my country. It has successively occurred in Guangdong, Guangxi, Fujian, Hainan, Yunnan, Guizhou, Hunan, Sichuan and other places. The damage is rampant, and the population continues to spread...

AI Technical Summary

Problems solved by technology

At present, the prevention and control methods for this insect are extremely scarce. The use of a large number of chemical pesticides not only cannot effectively kill B. dorsalis itself, but will also bring a huge negative impact on the orchard ecosystem and fruit production itself.
