Description

Essential oil composition and method for preventing and treating psyllium Technical Field The invention relates to the field of pest control, in particular to an essential oil composition and method for controlling psyllid. Background The psyllium (Liposcelis bostrychophila) is a worldwide distribution storage pest, mainly damages stored grains, books, archives, chinese medicinal materials and the like, is one of the main pests of organic matter cultural relics (such as ancient books, archives, animal specimens, silk and hair folk-custom cultural relics and the like) in a museum, has small size, short propagation period, is easy to generate drug resistance and extremely high control difficulty, mainly depends on chemical fumigating agents (such as phosphine and bromomethane) and pesticides such as pyrethroids, has serious drug resistance problem due to the long-term massive use of chemical pesticides, has various defects of pesticide residues, environmental pollution, potential risks on health of operators and the like, and has become urgent demands in the field along with the improvement of people on food safety and environmental protection consciousness. Pest control in museums and other places is a worldwide problem, and has extremely high requirements on the safety (no corrosion and no residue) of medicaments. The botanical pesticide is regarded as one of ideal substitutes for chemical pesticides due to the characteristics of natural source, easy degradation, relative safety to non-target organisms and the like, wherein the botanical essential oil is particularly suitable for fumigating and controlling pests in closed environments (such as warehouses and containers) due to volatility, a great deal of researches in the prior art report fumigating activity of a single botanical essential oil on various pests, and for example, published researches show that thyme essential oil, peppermint essential oil, lavender essential oil and the like all have certain biological activity on certain stored pests. However, the plant source control schemes disclosed in the prior art, especially those involving essential oil applications, are ubiquitous with the following drawbacks and deficiencies: Firstly, the use of a single essential oil often has the problems of insufficient activity or too high required effective concentration, and in order to achieve the ideal control effect, a large dosage is often required, so that the cost is increased, and the high concentration can bring uncomfortable smell or have potential influence on the quality of stored objects, so that the practical application potential is limited. Secondly, although the teaching of simply mixing and using various essential oils exists in the prior art, most of the essential oils stay on an empirical and rough compounding level, and the deep research on the structure-activity relationship between a specific compounding proportion and the bioactivity of the essential oils is lacked, most of the essential oils are simply mixed, the effects of the essential oils are mostly added, and even the essential oils are possibly antagonized mutually, so that the synergistic effect cannot be realized. Thirdly, for storage pests which are psyllid and are difficult to control, a special compound essential oil fumigation agent which has a synergistic effect and is clear in dosage is lacking in the prior art, and a person skilled in the art cannot obtain clear indication from the prior art so as to screen out the optimal essential oil combination and the accurate proportion thereof which have a remarkable synergistic effect on psyllid adults. Therefore, there is an urgent need in the art to develop an essential oil compound composition and method which have a remarkable synergistic effect against psyllids, particularly adults thereof, can reduce the dosage used, and are environmentally friendly. Disclosure of Invention In view of the above, the present invention aims to provide an essential oil compound composition and a method which have a remarkable synergistic effect against psyllids, particularly adults thereof, can reduce the dosage used, and are environmentally friendly. In order to achieve the above purpose, the invention provides an essential oil composition for preventing and treating psyllium, wherein the active ingredients of the essential oil composition comprise thyme essential oil and lavender essential oil, and the volume ratio of the thyme essential oil to the lavender essential oil is (8-10): 1. As a further improvement on the technical scheme, the volume ratio of the thyme essential oil to the lavender essential oil is 9:1. As a further improvement to the above technical solution, the essential oil composition is used for controlling psyllid adults. As a further improvement to the above technical solution, the essential oil composition functions by fumigation. As a further improvement on the technical scheme, the thyme essential oil comprises 35.17% of
