Problems solved by technology
However, the existing problem is that the black light lamps (ultraviolet to ultraviolet light range) mainly used in production are not effective in trapping rice leaf rollers. The use of light sources in other wavelength ranges is less, resulting in the high cost of studying monochromatic light in the wavelength range from purple to red light other than 420nm, so there are few experimental reports

Embodiment Construction
[0010] The present invention will be further described below in conjunction with specific embodiments.
[0011] 1.1 Source of test insects
[0012] The source of the adult S. chinensis is the overwintering generation of S. chinensis at the Fuyang Experimental Base of the China Rice Research Institute. It is divided into two parts, one part is the use of 200W incandescent lamps for light trapping and standby; The rice straw of the larvae or pupae of Diplodocus chinensis was placed in the net room, waited for its natural emergence, and was taken out for use every day. The trials were conducted between April and May of 2016-2017.
[0013] The adult population of the rice leafroller is the field population of the Fuyang Experimental Base of the China Rice Research Institute, which is captured daily from the field by artificial nets. The trials were conducted between July and September 2016-2017.
[0014] 1.2 LED light source
[0015] The light source is 15 kinds of monochromat...

The invention discloses a method for trapping striped rice borer and rice leaf folder by adopting double-LED monochromatic light compound wave bands and belongs to the technical field of agriculture.An LED illuminator adopted by the method emits light waves with the double-LED monochromatic light compound wave bands of 430+400nm. The method for trapping striped rice borer and rice leaf folder byadopting double-LED monochromatic light compound wave bands discovers that a range of effective monochromatic light waves for trapping striped rice borer and rice leaf folder is centralized at 360-520nm; the screened trapping effects is obviously superior to one double-monochromatic light combination 430+400nm of a reference band 380nm and a white light source; and due to use of the LED lamp, themonochromatic light of various bands and the light source of the compound wave bands are obtained, and the LED illuminator technology is mature gradually, so that the whole technical scheme is low incost, easy to realize and convenient to apply and popularize in future production.
Description
technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for trapping Diplodocus chinensis and Rice leafroller by adopting dual-LED monochromatic light composite wavelength bands. Background technique [0002] Rice is one of the most important food crops in the world. Rice is the staple food for more than half of the world's population. It is also the main food in my country and plays an important role in ensuring food security. Diploid and rice leafroller are both important pests of rice in my country, which have caused serious losses to rice production in my country. [0003] In the two main integrated control of rice, chemical control accounts for a large proportion, and even once became the main means of control. With the increase in the use of pesticides, the problems of environmental pollution, pesticide residues in rice and the growth of pest resistance have become increasingly prominent. However, as p...
