Description
Technical Field
The invention belongs to the field of pest control, and particularly relates to an active component of a daylily thrips trapping agent, a trapping agent and a trapping method.
Background
The day lily is called hemerocallis fulva and is also called day lily; it is rich in protein, fat, calcium, phosphorus, ferrum and vitamins, and has the effects of tranquilizing mind, promoting blood circulation, invigorating stomach, and promoting urination. Meanwhile, the daylily has strong adaptability, is easy to cultivate, has low requirements on soil and illumination conditions, and has low investment and quick response. However, the day lily is easy to be attacked by plant diseases and insect pests in the growth process, especially thrips, so that the yield of crops is reduced. Thrips belong to the Thysanoptera thysannoptera thrips superfamily thripidea, and over 2000 species of the genus 276 are known worldwide, including 4 subfamilies of the subfamily cynanchoviridae panchae, Dendrothripinae, serinochripinae sericosthripinae and thrithrips subfamily thrips. The insects of the family are widely distributed around the world, have complicated feeding habits, mainly comprise phytophagy, fungus feeding habits and predation habits, wherein the phytophagy accounts for more than half of the feeding habits, and are one of important economic pests. The thrips uses imagoes and nymphs to file and suck the juice of young tissues (branches, leaves, flowers, fruits and the like) of plants, and the damaged young leaves and young tips become hard, curl and wither, so that the plants grow slowly and internodes are shortened; young fruits (such as eggplants, cucumbers, watermelons and the like) are hardened after being damaged, and fruit drop is caused in severe cases, so that the yield and the quality are seriously influenced.
The thrips are mainly harmed by adults and nymphs on the backs of leaves or in the slits of heart leaves of the flower shoots at spring and summer crossings on the day lily, leaves become thin after tender leaves are damaged, grey white or grey brown streak spots appear on two sides of the midrib of the leaves, and the epidermis is grey brown, deformed and curled and has weak growth potential; the flower bud becomes short and small after being damaged, the flower stalk has yellow brown filing trace, and the flower bud bends when serious, thus losing commodity value. Due to the high propagation speed of the thrips, if the thrips cannot be prevented and controlled in time, disastrous damage can be caused, the growth of plants and the quality of flower buds are seriously influenced, and the yield and the commodity quality of the day lily are directly influenced.
The prevention and treatment method of thrips mainly comprises agricultural prevention and treatment, physical prevention and treatment and chemical prevention and treatment. The agricultural control method is to remove field weeds and dead branches and leaves in early spring, burn or bury deeply and eliminate overwintering imagoes and nymphs. The management of fertilizer and water is enhanced, the plants are enabled to grow strongly, and the harm is reduced. The physical prevention and control means that blue sticky boards are arranged in the field to trap and kill adults by utilizing the blue and yellow habits of thrips, and the height of the sticky boards is equal to that of crops. The chemical prevention and control mainly uses 35 percent of thiamethoxam suspension seed coating agent, 25 percent of thiamethoxam water dispersible granule 3000-. Agricultural control and physical control consume a large amount of manpower and physics and the control effect on thrips is not obvious. Therefore, from the viewpoint of ecological environment and food safety, finding stable and efficient green prevention and control technologies has become the key work of modern pest control. The pheromone prevention and control in the novel green prevention and control technology has the advantages of high selectivity, good safety, small influence on an ecosystem and the like, is an indispensable important component in the comprehensive prevention and control of pests, and the research on the green, safe and effective prevention and control technology becomes a trend for the development of modern agriculture and forestry.
Pheromones are chemical substances for information exchange between and within insect species, and some of the pheromones identified in thrips include aggregation pheromone (aggregation pheromone), sex pheromone (sex pheromone), alarm pheromone (alarm pheromone), contact pheromone (contact pheromone), and the like. The aggregation pheromone is an important component of insect semiochemicals and has the function of attracting swarming, and meanwhile, the aggregation pheromone is an important food source signal and attracts male and female adults and nymphs to eat before. The gathering pheromones of thrips include five kinds of (R) -lavandulyl-3-methylbutanoaat, (R) -lavandulol, (S) -2-methylbutanoate, (R) -lavandulyl acetate neryl and (E, E) -farnesyl acetate, which are mainly used for attracting female insects, facilitating mating and mating positioning. The sirens deccyl acetate and dodecyl acetate not only induce the 2-year old thrips to fall from the host and thus reduce the female spawning, but also attract predatory insects such as Amblyseius cupmeris (Amblyseius Neoseiulus cupmeris) and Orius triticolus tritici. The contact pheromone 7-methytricosine is generated by male imagoes, the amphoteric imagoes can perform behavioral reaction only when contacting the substance, and the mutual recognition among species plays an important role; the diamyl adipate and diamyl glutamate can induce the behavioral response of thrips, and the pheromone can be applied to the mating interference of thrips. Meanwhile, phytophagous pests mainly feed stems, leaves, fruits, nectar and the like of plants, and often show obvious preference to some plants, which is the result of environmental adaptation of insects in the long-term evolution process. Plant volatile matters play an important role in pest food preference selection behaviors, and the food attractant (also called as 'plant-source attractant') developed based on pest preference food sources or volatile matters thereof is an important green pest prevention and control product
Thrips is used as a rasping-sucking type pest, the patent on the prevention and the treatment of the pest is mainly an imidacloprid compound agent (CN 199510016465.2), the main components mentioned in the patent are imidacloprid, nereistoxin, pyrethrins, organophosphorus, carbamates and heterocyclic pesticides; nitrogenous heterocyclic compounds having insecticidal activity, their preparation and use (CN 200810205009.0); oxime ether dichloro allyl ether compounds (CN 201110163149.8) with insecticidal activity, wherein the main component of the compound is oxime ether dichloro allyl ether compounds; a composition (CN 200810190739.8) containing oxadiazine and pyrazole pesticide comprises indoxacarb and butene fipronil and ethiprole as pyrazole pesticide; these are all compounded agents and have broad-spectrum killing property, and no report about thrips specific attractant is found at present.
In the practice of pest control, the attraction of a plant-derived attractant prepared from host plant volatiles to insects plays an important role in pollution-free comprehensive control. The reaction of the insects to plant volatile components is determined, active components are screened and identified and developed into an attractant, and the attractant is synergistic with the aggregation pheromone of the insects, so that the attractant is an important direction for safe control of the insects, and has important significance for reducing the use of conventional chemical pesticides, further preventing the development of the drug resistance of the insects and protecting the environment.
