本发明属于生物防治领域，具体是一种控制日本追寄蝇种群的方法。The invention belongs to the field of biological control, and in particular relates to a method for controlling the population of Japanese parasitoid flies.
日本追寄蝇
Exorista japonica (Townsend) （双翅目 Diptera 寄蝇科 Tachinidae）是大卵型寄生蝇，雌蝇将卵产至寄主体表，幼虫孵化后钻至寄主体腔内，最后在寄主幼虫或蛹期钻出寄主化蛹；其可寄生多种农林业害虫，包括美国白蛾、松毛虫、黏虫、菜粉蝶、玉米螟等30多种鳞翅目害虫。日本追寄蝇被释放到自然界后，其种群在自然条件下的难以再控制，近几年发现有日本寄蝇寄生危害家蚕（
Bombyx mori L.）幼虫。现有技术一般采用物理法以及药物法避免追寄蝇对家蚕的寄生，比如采用灭蚕蝇或者拉网，但是药物对家蚕存在危害，会造成蚕死亡，防蝇装置主要针对蚕室且效果不佳，对于大棚养殖不适用。因此，在生物防治上迫切需要开放一种方法对释放的天敌种群加以控制，另外，在蚕区也需要对日本追寄蝇的种群进行控制，使其在经济危害水平之下，实现生物防治和蚕业安全生产的平衡发展。
Japan 's chase of the flying flies (TowNSEND) (TowNSEND) (TACHINIDAE) is a large egg parasitic fly. Female flies will produce eggs to the main table. After the larvae hatch, they will drill out of the host larvae or pupae. Pests, including more than 30 types of bulge -winged pests such as American white moth, pine caterpillars, sticky worms, vegetable powder butterflies, corn crickets. After the Japanese parasitic fly was released into the natural world, its population is difficult to control under natural conditions. In recent years, it has been found that the Japanese parasitic fly parasitizes and harms the larvae of silkworm ( Bombyx mori L.). In the prior art, physical methods and drug methods are generally used to avoid the parasitism of silkworms by chasing flies, such as killing silkworms or pulling nets, but drugs are harmful to silkworms and will cause silkworms to die. Therefore, there is an urgent need to open a method to control the released natural enemy population in biological control. In addition, it is also necessary to control the population of Japanese parasites in silkworm areas, so that it can achieve a balanced development of biological control and sericulture production safety under the level of economic harm.

针对目前尚无有效的方法控制日本追寄蝇种群及其在蚕业生产上的危害，本发明首次公开了一种利用家蚕控制生产上日本追寄蝇种群的新方法，下面对本发明的具体实施方式进一步的详细描述。At present, there is no effective method to control the population of Japanese parasites and its harm in sericulture production. The present invention discloses a new method for controlling and producing the population of Japanese parasites by using silkworms for the first time. The specific embodiments of the present invention will be further described in detail below.
实验材料：家蚕品种：菁松×皓月、秋丰×白玉、苏豪×钟晔等品种，具有家蚕一般品种的普遍性特征。日本追寄蝇：苏州大学蚕桑研究所资源。追寄蝇成虫饲料：蜜糖与香精混合物。家蚕饲养为常规方法。家蚕体表如有追寄蝇卵，蝇卵大小和外形类似白色芝麻粒，容易分辨。Experimental materials: Bombyx mori species: Jingsong×Haoyue, Qiufeng×Baiyu, Suhao×Zhongye and other varieties, which have the universal characteristics of common silkworm varieties. Japanese chasing parasites: resources from the Institute of Sericulture, Soochow University. Feed for parasitoid adults: a mixture of honey and essence. Silkworm rearing is a conventional method. If there are fly eggs on the body surface of the silkworm, the size and shape of the fly eggs are similar to white sesame seeds, so they are easy to distinguish.
实施例一 环境中日本追寄蝇种群的控制方法：在2020年5月春蚕生产前，在江苏省如皋市的东陈镇、搬经镇和磨头镇分别选取四块1000平方米的养蚕区，互相间隔，各自养蚕区的追寄蝇互不影响；对照区饲养常规家蚕品种（大棚育，苏豪×钟晔）；试验区在对照区的基础上，在室外暴露饲养至5龄的菁松×皓月幼虫，每个试验区的东、南、西、北角和中间各投放1000头用于吸引追寄蝇寄生；对比区在对照区的基础上，在室外暴露饲养至5龄的秋丰×白玉幼虫，每个试验区的东、南、西、北角和中间各投放1000头；诱饵区在对照区的基础上，在室外暴露饲放置追寄蝇成虫饲料：蜜糖与香精混合物，每个试验区的东、南、西、北角和中间均匀放置。养殖结束后采用追寄蝇成虫饲料引诱环境中的日本追寄蝇，统计种群数量，日本追寄蝇种群数量在本发明方法使用前后的变化情况如表1所示。Example 1 Control method of Japanese parasitoid fly population in the environment: Before the spring silkworm production in May 2020, four sericulture areas of 1,000 square meters were selected in Dongchen Town, Qianjing Town and Motou Town of Rugao City, Jiangsu Province respectively, separated from each other, and the parasitism flies in each sericulture area did not affect each other; the control area was raised with conventional silkworm species (greenhouse cultivation, Suhao × Zhongye); the test area was based on the control area, and the 5-year-old Jingsong × Haoyue larvae were exposed outdoors and reared to 5 instars In the east, south, west, north corners and middle of each test area, 1000 larvae were placed in the east, south, west, north and middle of each test area to attract parasitism; in the comparison area, on the basis of the control area, 1000 Qiufeng × Baiyu larvae were raised outdoors to the 5th instar, and 1000 larvae were placed in the east, south, west, north corner and middle of each test area; on the basis of the control area, the bait area was placed in the outdoor exposure feeding. . After breeding, adopt the japonica adult feed to lure the japonica in the environment, count the population size, and the change situation of the japonica population before and after the method of the present invention is used is as shown in table 1.
。
.
表1结果显示：对照区日本追寄蝇的种群平均数量为193头/1000平方米，使用本发明方法控制追寄蝇种群数量，日本追寄蝇种群数量下降了86%，因此使用本发明方法能有效控制蚕区追寄蝇种群数量，而且菁松×皓月可常规上蔟采茧，一方面不影响结茧率，另一方面追寄蝇无法破茧而致死。调查其他养殖区，有采用灭蚕蝇措施的，对比而言，灭蚕蝇措施没有本发明方法控制追寄蝇种群数量的效果好，且灭蚕蝇导致家蚕死亡。The results in Table 1 show: the average number of populations of Japanese parasites in the control area is 193 heads/1000 square meters. Using the method of the present invention to control the population of parasites, the population of parasitoids in Japan has dropped by 86%. Therefore, the method of the present invention can effectively control the population of parasites in silkworm areas, and Jingsong × Haoyue can routinely go up to pick cocoons. Investigate other breeding areas, there are those who adopt measures to kill silkworm flies. Comparatively speaking, the measures to kill silkworm flies are not as effective as the method of the present invention to control the population of chasing flies, and killing silkworm flies leads to the death of silkworms.
。
.
表2结果显示：室外未暴露饲养菁松×皓月的家蚕养殖区，追寄蝇寄生率较高，达到40%；室外暴露饲养菁松×皓月的家蚕养殖区，追寄蝇寄生率较低，只有2%。因此使用本发明方法可以有效保护养殖蚕，减少追寄蝇的寄生率。The results in Table 2 show that in the silkworm breeding area where Jingsong × Haoyue was reared without outdoor exposure, the parasitism rate of parasitoid flies was higher, reaching 40%; in the silkworm breeding area where Jingsong × Haoyue was raised outdoors, the parasitism rate of parasitism flies was lower, only 2%. Therefore, using the method of the invention can effectively protect the cultured silkworms and reduce the parasitic rate of chasing flies.
实施例二 日本追寄蝇寄生对蚕茧质量的影响：将家蚕（菁松×皓月）常规饲养至5龄起蚕，置于日本追寄蝇饲养的笼中寄生，选择被寄生家蚕幼虫1000头，饲养至上蔟结茧，对照区无日本追寄蝇寄生。调查雌雄各50粒，取平均值，统计结茧率、全茧量，茧层量，统计茧层率。经统计，表明被寄生个体和未被寄生个体均能正常结茧，结茧率达99%，无显著差异。全茧量和茧层率也无显著差异，表明采用5龄家蚕幼虫用于控制日本追寄蝇，不会影响蚕茧的产量和质量，具体见表3。Example 2 Effect of parasitism by Japanese parasitoids on the quality of silkworm cocoons: Bombyx mori (Jingsong x Haoyue) were routinely reared to the fifth instar silkworms, placed in cages raised by Japanese parasitoids for parasitism, and 1000 parasitized silkworm larvae were selected and reared until cocooning in the upper cocoon. There was no parasitism by Japanese parasitoids in the control area. Investigate 50 capsules of each male and female, take the average value, and count the cocooning rate, the amount of full cocoons, the amount of cocoon layers, and the rate of cocoon layers. Statistics show that both parasitized individuals and non-parasitized individuals can cocoon normally, and the cocooning rate reaches 99%, with no significant difference. There was also no significant difference in the amount of whole cocoons and the rate of cocoon layers, indicating that the use of 5th instar silkworm larvae to control the parasite fly will not affect the yield and quality of silkworm cocoons, see Table 3 for details.

5龄之前家蚕被追寄蝇寄生后，寄生率高，被寄生的家蚕发育质龄眠蚕期后，大量家蚕无法蜕皮变态，导致死亡，对蚕业生产危害极大。现有技术以开发新型的药物来防治家蚕追寄蝇为主，除化学药物防治外，也应用其他防治方法，如物理防治，利用家蚕追寄蝇的趋光性和对不同光谱的选择性，设置具有引诱捕杀功能的发光引诱器进行防治，或者利用家蚕追寄蝇成虫对某些化学物质的敏感性，配置具有化学引诱功能的装置进行捕杀。但是现有方法的效果不明显，且有时对家蚕养殖产生危害。本发明采用纯生态方法，创造性的提出以菁松×皓月家蚕来控制追寄蝇种群，大幅降低了家蚕养殖区追寄蝇种群数量，且对养殖的家蚕没有危害，提高了高价值家蚕的养殖成果。After the silkworm is parasitized by the chasing fly before the 5th instar, the parasitism rate is high. After the parasitized silkworm develops the quality age and sleeps silkworm stage, a large number of silkworms cannot molt and metamorphosis, resulting in death, which is extremely harmful to sericulture production. The prior art mainly focuses on the development of new drugs to prevent and control the silkworm chasing fly. In addition to chemical drug control, other control methods are also used, such as physical control. Using the phototaxis of the silkworm chasing fly and the selectivity to different spectra, a luminescent attractor with a lure and killing function is used for prevention and control, or the adult silkworm chasing fly is used. But the effect of existing method is not obvious, and produces harm to silkworm breeding sometimes. The present invention adopts a pure ecological method, and creatively proposes to control the population of chasing flies with Jingsong × Haoyue silkworm, which greatly reduces the population of chasing flies in silkworm breeding areas, has no harm to the cultured silkworms, and improves the breeding results of high-value silkworms.
