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

[0031] 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).

[0032] Table 1 Release Rate mg / sachet / week

[0033]

[0034] The results showed that the system could simultaneously release 2-phenylethyl alcohol and methyl salicylate. Those skilled in the art will recognize that there are other methods 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

[0036] Aiming at different combinations of attractants, the attractiveness of them to the wasps in fruit trees (apple) was compared. With the volatile matter described in the embodiment 1 of 500mg, every tree hangs a pouch, and the pouch of every kind of mixture hangs 10 trees. 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.

[0037] 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.

[0038] The results are shown in Table 2.

Embodiment 3

[0044] 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.

[0045] The observer selects 10 clusters of flowers on the branches of the north side and the south side of 5 trees among the trees treated by five kinds of volatiles described in embodiment 2, and counts the high-quality fruit quantity (diameter is greater than 20mm and counts as high-quality fruit).

[0046] The results are shown in Table 3.

[0047] Table 3 The number of high-quality fruit per 5x10 flower clusters of apples pollinated by wall bees

[0048]

[0049] The number of high-quality fruit was significantly higher in the treated trees, especially in the trees treated with the 40:60 mixture. Since methyl salicylate itself has no attraction to wall bees, it can be seen that it has a synergistic effect on attracting wall be...

Abstract

The invention provides an osmia attractant as well as a use method and application. The osmia attractant comprises the following components in parts by weight: 20-80 parts of 2-phenethyl alcohol and 20-80 parts of methyl salicylate. When being used, the osmia attractant is put into a plastic controlled-release device. The osmia attractant provided by the invention is used for enhancing crop pollination in the controlled-release device, and when being used in the controlled-release device, the osmia attractant is capable of improving activity of osmia and increasing fruit setting rates, and forfruit farmers with osmia pollination, the pollination rate can be increased, and the purposes of increasing fruit setting rates, increasing the yield and improving the 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. Using bees as pollinators is more efficient and yields more fruit per acre, especially the bees are now being cultivated and used by Chinese farmers. [0003] In the West, the main pollinator is the European honey bee, which produces honey and beeswax as well as pollination. Although this species is also common in China, most fruit trees, including apples ...
