Problems solved by technology

Among pollinating bees, bees are relatively easy to be affected, while wall bees are pollinator species that are very difficult to be affected. At present, other attractants have no effect on attracting wall bees, and no one has previously discussed which type of attractant is effective. The wall bee has done specialized research effectively

Embodiment 1

[0036] The controlled-release device is a low-density polyethylene zipper pouch with a wall thickness of 0.5mm and a size of 2.5*1cm. Each sachet contains 500mg of wasp attractant, these sachets are closed with a zipper and further heat sealed. Weighed weekly for 42 days, the release rates of individual components and combinations were measured at room temperature (18°C to 23°C).

[0037] Table 1 Release Rate mg / sachet / week

[0038]

[0039] The results showed that the system could simultaneously release 3,7-dimethyl-2,6-octadien-1-ol and methyl salicylate. Those skilled in the art will recognize that there are other means of achieving controlled release of these compounds and mixtures, such as wax matrices, squeeze-sealed polyethylene tubing, and bottles made of other suitable polymers such as plasticized polyvinyl chloride. These can also be used as controlled release systems.

Embodiment 2

[0041] Aiming at different combinations of attractants, the attractiveness of them to the wasps in fruit trees (apple) was compared.

[0042] With the volatile matter described in the embodiment 1 of 500mg, every tree hangs a sachet, and the sachet is the same as embodiment 1, and the sachet of every kind of mixture hangs 10 trees.

[0043] Trees chosen for experiments should be equidistant from the wasp nests placed by fruit growers. The apple orchards used for the experiment had negligible numbers of bees as well as artificially released wall bees.

[0044] The observer selected 5 trees from the trees treated with five volatile compound combinations (50 minutes each), marked 10 clusters of flowers on their north and south sides respectively, and recorded the number of flower visits by wall bees within 1 minute. . No attractants were hung on the trees of the control group.

[0045] The results are shown in Table 2.

Embodiment 3

[0050] To compare the fruit set rate of apple trees in orchards releasing the wall bee for different attractant combinations. The apple orchards used for the experiment had negligible numbers of bees as well as artificially released wall bees.

[0051] Among the five kinds of volatile-treated trees described in Example 2, the observer selected the north and south sides of five trees.

[0052] 10 clusters of flowers on the side branches were used to count the number of high-quality fruit (diameter greater than 20mm is counted as high-quality fruit).

[0053] The results are shown in Table 3.

[0054] Table 3 The number of high-quality fruit per 5x10 flower clusters of apples pollinated by wall bees

[0055]

[0056]

[0057] The number of high-quality fruit was significantly higher in the treated trees, especially in the trees treated with the 50:50 mixture.

Abstract

The invention provides an osmia attractant as well as a use method and application thereof. The osmia attractant comprises the following components in parts by weight: 20-80 parts of 3,7-dimethyl-2,6-octadiene-1-alcohol and 20-80 parts of methyl salicylate. When being used, the osmia attractant is put into a plastic release-controlled device. The osmia attractant provided by the invention is put into the release-controlled device to enhance crop pollination, when the osmia attractant is used in the release-controlled device, the activity of osmia can be improved, the fruit setting rate can beincreased, the pollination rate can be increased for fruit farmers with osmia pollination, and the purposes of increasing the fruit setting rate, increasing yields and improving quality can be achieved.

Description

technical field [0001] The invention relates to the technical field of bee pollination, in particular to a bee attractant, a use method and its application in bee pollination. Background technique [0002] Most flowering plants require insects for pollination, and most bees are pollinating insects. If the flowers are not pollinated and the seeds are not fertilized, fruit cannot form. In the absence of insect pollinators, it is necessary for farmers to use paint brushes for hand pollination, which has become a common practice in northern China and is labor-intensive, costly and inefficient compared to insect pollinators. [0003] There are many kinds of bees, which can be roughly divided into pollinator bees and non-pollinator bees, among which pollinator bees include honeybees, European bees, bumble bees, wall bees, etc. Most of them visit flowers mainly to produce honey and beeswax, and by the way complete Pollination work, and the wall bees among them do not produce hone...
