Description

Method for combined control of rice pests and application thereof
Technical Field
The invention belongs to the technical field of rice pest control, and particularly relates to a method for jointly controlling rice pests and application thereof.
Background
Rice (Oryza sativa L.) is susceptible to Chilo suppersalis, tryporyza incertulas, cnaphalocrocis medinalis and other insect pests in the growth and development process, and can cause reduction of rice tillering, delay of growth period, withered booting and white ears, influence flowering and fructification, improvement of empty hull rate and reduction of thousand seed weight, thereby causing reduction of yield, quality and the like. Chilo suppressalis, cnaphalocrocis medinalis guenee and the like are main pests of rice, chemical pesticides are mostly used in the conventional prevention and control method at present, but the unreasonable use of the pesticides easily causes the problems of crop phytotoxicity, pest resistance, pesticide residue standard exceeding, environmental pollution of rice fields and water areas and the like, so that the green prevention and control technology is adopted to prevent and control the diseases and insect pests of the rice fields, the important technical support for ensuring that the ration is full and good at the same time is provided, and the important composition of pesticide reduction and environmental ecological management is provided.
The green prevention and control technology mostly adopts a mode of sex attractant or food attractant, and the sex attractant refers to chemical substances having a sex attraction effect on mature animals and comprises sex pheromone and analogues having similar effects; the food attractant is a substance that attracts food odor (or hormones, wave bands, etc.) to animals. At present, double-control mode researches are carried out on green prevention and control technologies for crops such as cotton, peanuts and the like, for example, the food attractant and the sex attractant are used for cooperatively preventing and controlling the cotton bollworms of the peanuts, and in the aspect of green prevention and control of rice, because the existing double-control mode researches show that the combined prevention and control can be mutually influenced and the effect of the combined use of the two attractants is not good, the green prevention and control aspect of the rice in the field still stays at the prevention and control level of a single attractant or a single pest species, but in the practical production application, the phenomenon that a plurality of pests coexist and are harmful is caused. Therefore, a method for combined control of rice pests is urgently needed in the field, and the method can be used for comprehensively controlling the rice pests so as to achieve the purposes of cost saving and efficiency improvement.
Disclosure of Invention
In view of this, the present invention provides a method for combined control of rice pests, which uses two or more feeding attractants and/or sex attractants simultaneously to perform comprehensive control of rice pests, thereby saving the insect-catching cage, reducing the labor cost for placing the insect-catching cage and replacing the lure, and achieving the purposes of comprehensive control, cost saving and efficiency improvement.
In order to achieve the above object, the present invention provides the following technical solutions:
the invention provides a method for jointly controlling rice pests, which comprises the following steps: the trapping devices are placed in the rice field every 667m 2 1-2 trapping devices are placed to ensure that the trapping devices are always 20-30 cm higher than the leaf surfaces of the rice; the trapping device at least comprises two trapping cores.
Preferably, the lure comprises a food attractant, a sex attractant, a hormone attractant and a scent attractant.
Preferably, the phagostimulant comprises a biological phagostimulant of the oryza sativa leaf roller.
Preferably, the sex attractant comprises a luridol chilo suppressalis sex attractant.
Preferably, the rice pests comprise rice leaf rollers, chilo suppressalis, tryporyza incertulas and rice planthoppers.
Preferably, the time for placing the trapping device is the rice green turning period.
Preferably, the method also comprises the step of replacing the lure in time within the effective period of the lure.
The invention also provides application of the method in rice planting.
The invention also provides application of the method in improving the quality and/or yield of rice.
The invention has the beneficial effects that:
the chemical pesticide can cause environmental pollution, increase of rice pesticide residues, reduction of rice quality and the like, and compared with the traditional chemical pesticide for preventing and treating lepidoptera pests, the method disclosed by the invention has the effects of being more environment-friendly and reducing the amount of the pesticide. Compared with the existing green prevention and control technology, the existing food attractant or sex attractant prevention and control technology can only prevent and control single pests, and the food attractant and the sex attractant are considered to interfere with each other.
The invention reduces ovulation and larva generation by inhibiting the number of the lepidoptera pests in the early period of outbreak, greatly reduces the probability of large-area outbreak of pest disasters, and reduces the damage of the pests to plants. The method of the invention traps and kills pests by the temptation of food or sex hormone, solves the problems of single prevention and control mode, small trapping strength and the like of the rice pests in the prior art, realizes comprehensive trapping, can trap one pest by food attraction and sex attraction, and can trap different pests by food attraction and/or sex attraction simultaneously, thereby achieving the effect of trapping more pests.
