Description

Technical Field

[0001] The invention relates to the technical field of agricultural pest control, and more specifically, to an ornamental rapeseed Pieris rapae dynamic control device and a use method thereof. Background Art

[0002] Ornamental rapeseed has the advantages of bright colors, long flowering period and high economic benefits, and has become a dominant crop to promote the revitalization of rural industries. However, cabbage loopers (rapeseed butterfly larvae) harm rapeseed leaves and buds. In severe cases, the leaf loss rate can reach 90%, which hinders the growth and development of rapeseed, reduces the ornamental effect and economic value, and seriously restricts the development of the ornamental rapeseed industry. Traditional single pest control methods, such as chemical control, biological control, and physical control, all have many disadvantages. Chemical control is easy to cause environmental pollution and reduce the number of natural enemies. In particular, the safe interval of chemical pesticides is mostly more than 3 days. For areas with frequent tourist activities such as urban landscapes and agricultural sightseeing parks, pesticide residues may pose a potential threat to human health. In addition, biological control, such as the application of microbial agents such as Bacillus thuringiensis and Beauveria bassiana, the release of natural enemies, and physical control methods, such as manual capture and the setting of insect-proof nets, are restricted by environmental factors. For large-scale ornamental rapeseed, it not only consumes a lot of manpower and material resources, but also has limited control effects.

[0003] At a time when the ornamental rapeseed industry is booming, rapeseed pest control faces many difficulties, mainly manifested in the lack of in-depth "IPM" integrated pest control concept, single control methods, lack of equipment capable of integrated pest control, and the misunderstanding that pests need to be completely eliminated. There are also devices on the market that combine the two control methods, such as pheromone light source double lure traps, but the equipment is still based on the purpose of eliminating pests and is not suitable for the control of ornamental rapeseed pests. The ornamental value of ornamental rapeseed consists of "viewing flowers" and "viewing butterflies". It is necessary to control the harmful cabbage loopers within the control threshold, obtain more adult cabbage butterflies, and create higher social and economic benefits. At present, ornamental rapeseed fields mainly reduce the damage of cabbage loopers through chemical control and biological control, and raise cabbage butterflies through artificial breeding, and release them during the rapeseed flowering period to attract tourists. This method is costly and time-consuming, so it is urgent to develop innovative devices and methods that take into account both the control of larval cabbage loopers and the regulation of the population of adult cabbage butterflies.

[0004] The present invention is based on the rhythmic difference between the larvae of Pieris rapae (nocturnal) and the adult of Pieris rapae (diurnal), and utilizes the "push-pull" theory of integrated pest control to provide an efficient, environmentally friendly, and sustainable ornamental rapeseed flower-Pieris rapae dynamic control device, which has important practical significance. Summary of the invention

During the day, the device can attract the rapeseed butterfly with a trap made of sex pheromone or natural plant extracts, thereby improving the ornamental value and dynamically controlling the number of the rapeseed butterfly population, implementing the "IPM" integrated pest control concept, achieving efficient and environmentally friendly prevention and control of ornamental rapeseed pests, and at the same time, simplifying the operation and reducing the labor intensity.
