Technical Field
The invention relates to the technical field of jujube fruit fly attractants, and particularly relates to a high-efficiency jujube fruit fly attractant.
Background
The trypetidae insects have deep harm degree to economic crops and wide host range, so that the trypetidae insects are listed as quarantine pests in many countries. Wherein the fructus Jujubae fly is also one of the shells of fructus Jujubae fly for several months. The harm of the bactrocera dorsalis on the jujube trees is mainly that imagoes lay eggs on the jujube fruits to form egg laying holes, so that the abnormal development of jujube fruit tissues around the egg laying holes is caused, irregular pits or tumors are formed, and the quality of the jujube fruits is easily influenced. Then, eggs develop into larvae, and the larvae begin to eat the jujube fruits from outside to inside, so that the jujube fruits are premature or rotten, and the yield of the jujube fruits is greatly reduced. The fructus ziziphi spinosae is controlled in Xinjiang, but the fructus ziziphi spinosae still causes certain loss to local jujube industry, and the fructus ziziphi spinosae is colonized in Xinjiang, so that the fructus ziziphi spinosae risks invading other jujube producing areas in China. The jujube fruit fly is an important special fruit-eating pest of jujube plants and is listed in the name list of imported plant quarantine harmful organisms in China. In 2007, the Chinese jujube fruit flies are found in Turpan area in Xinjiang for the first time, and the serious influence is brought to the local jujube industry. In addition, most areas in China are suitable for colonization of the Chinese jujube flies, once the Chinese jujube flies are spread and diffused in Chinese jujube tree planting areas in China, the benefits of Xinjiang and even Chinese jujube farmers are seriously damaged, the export trade of jujube products is influenced, huge loss is brought to the jujube farmers, and meanwhile, the safety of the Chinese jujube industry and the healthy development of the whole jujube industry are directly threatened. In view of the great economic significance of the jujube fruit fly, the development of the prevention and control of the jujube fruit fly and the scientific research thereof are inevitable. For quarantine pests which have occurred locally, the accurate and timely judgment of the existence of an epidemic situation in a region is the basis and key of prevention and control.
However, research on the jujube fruit fly monitoring technology is not carried out so far, and yellow boards are still used for forest monitoring, so that the effect is poor. The monitoring attractant based on the jujube fruit fly pheromone is developed, and has great significance for timely and accurately grasping the occurrence hazard of the jujube fruit flies and understanding population dynamics. The attractant for inducing the jujube fruit flies in the prior art can simultaneously attract male flies and female flies, once the attractant is excessively consumed by the male flies, the female flies cannot be continuously attracted, the damage of the female flies to the jujube fruits is far greater than that of the male flies, and the un-attracted female flies have great influence on fruit trees.

The trapping site is selected as the host plant as the hanging point of the trap, but not directly shielded by the leaves or exposed to the sun, the hanging point is generally selected to be 1.3m from the ground, the traps and the attractant-carrying polyethylene slow-release pouch are replaced every 7d, and when a plurality of traps are installed, the spacing between each trap is at least 50 m.
Example 4:
the invention provides a high-efficiency drosophila melanogaster attractant which comprises, by weight, 6-12 parts of farnesene, 4-7 parts of nonanal, 4-7 parts of ethyl acetate, 5-8 parts of caryophyllene, 5-8 parts of ocimene, 3-12 parts of phellandrene and 4-10 parts of kafirene, and comprises, by weight, 10-16 parts of clear water as an auxiliary material.
Specifically, in this embodiment, the used raw materials (by weight) include 12 parts of farnesene, 7 parts of nonanal, 7 parts of folic alcohol acetate, 8 parts of caryophyllene, 8 parts of ocimene, 12 parts of phellandrene, and 10 parts of kamtene, and the used auxiliary materials (by weight) include 16 parts of clear water.
The invention also comprises a preparation method of the drosophila ziziphus attractant, which comprises the following specific steps:
taking seven test tubes, sequentially adding a proper amount of clear water into the test tubes, then sequentially adding a proper amount of farnesene, nonanal, folic alcohol acetate, caryophyllene, ocimene, phellandrene and kame into each test tube, and then stirring the mixed liquid in the test tubes respectively to dilute the farnesene, nonanal, folic alcohol acetate, caryophyllene, ocimene, phellandrene and kame;
and step two, taking another test tube, pouring the diluted farnesene, nonanal, folic alcohol acetate, caryophyllene, ocimene, phellodendrene and kaemprene into the test tube in sequence, and stirring at a low speed in the adding process to ensure that the farnesene, the nonanal, the folic alcohol acetate, the caryophyllene, the ocimene, the phellodendrene and the kaemprene can be fully mixed to prepare the attractant.
The use method of the attractant comprises the following steps: when the jujube fruit flies are trapped, a certain amount of trapping agent is sucked by a liquid transfer machine and dripped on absorbent cotton (the usage amount of the absorbent cotton is suitable for completely absorbing the attractant), the absorbent cotton is placed into polyethylene slow-release small bags with different specifications, then the polyethylene slow-release small bags loaded with the attractant are placed into an ice box, after the trapping site is reached, the pest sticking plate is firstly stuck to the bottom of the triangular trapping device, then the polyethylene slow-release small bags are hung in the trapping device (the small bags are prevented from being broken in the hanging process), and finally the trapping device is hung in the trapping site. The trapping site is selected as the host plant as the hanging point of the trap, but not directly shielded by the leaves or exposed to the sun, the hanging point is generally selected to be 1.5m from the ground, the traps and the attractant-loaded polyethylene slow-release pouch are replaced every 7d, and when a plurality of traps are installed, the spacing between each trap is at least 50 m.
Example 5:
the amount of the zaocys dhumnades in the actual trapping of the trapping agents prepared in examples 1 to 4 was counted (counting the amount of the zaocys dhumnades in the polyethylene slow-release pouch at the first replacement), and the amount of the female zaocys dhumnades and the male zaocys dhumnades were counted, respectively, to obtain the following data:
as can be seen from the above table, the mixture ratio of the raw materials in example 4 is moderate, the ratio of the female zaocys zizanoides to the total number of the captured zaocys zizanoides is the largest, and the trapping agent prepared in this example can attract more magnetic zaocys zizanoides compared to examples 1 to 3, wherein the trapping agent attracts the female zaocys zizanoides most. Therefore, the attractant prepared by the embodiment can attract more female Chinese date fruit flies in other attractants of the same type, so that the number of the female Chinese date fruit flies in an orchard can be effectively reduced, and the phenomenon that the normal growth of fruits is influenced by the fact that the female Chinese date fruit flies lay eggs on the fruits of the jujube trees is prevented.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
