A multi-bee and bee-mixed bee drone launched a new breakthrough in the treatment of red-eye bee
The use of Trichogramma to control corn borer, this biological control technology of "worm control" has been applied in China for decades, and has shown good control effects in many applications such as Jilin and Beijing. In recent years, with the continuous advancement of scientific research and technology, Trichogramma has achieved new breakthroughs in the treatment of insects. On June 30, at the on-site production and bio-defense observation meeting of Trichogramma in Jilin Changchun, the reporter saw that Trichogramma can not only be used to control corn borer, but also to deal with rice stem borer and achieve A large number of eggs, mixed bees, drones, greatly improved the control effect and prevention efficiency, and other green control technology assembly and application, can achieve the basic use of chemical pesticides. One ball can release three kinds of Trichogramma at the same time On the morning of June 30, in a 10,000-acre rice base in Wanchang Town, Yongji County, Jilin Province, a small drone vacated and flew over the rice fields. From time to time, the next ball was thrown. It is the natural enemy of rice stem borer, the red-eye bee. Looking up and looking at it, you will find that this seemingly ordinary ball is very popular. Wang Chengzhi, the agricultural technology promotion center of Yongji County, said that the ball-type bee-keeping device contains three different red-eye bees. One white-colored tussah eggs are Trichogramma and Trichogramma. On the small bee card is Trichogramma, each of which contains about 4,000 Trichogramma, among which the ratio of Trichogramma, Trichogramma and Trichogramma is 1 : 3:8. After being released into the field, the Trichogramma, which is less than 1 mm in size, will look for the egg mass of the rice stem borer and produce its own eggs, thereby achieving the effect of "worm control". "We found that Trichogramma ostriniae has the best control effect on rice stem borer, while the pine caterpillar, Trichogramma and Trichogramma, because of the large egg breeding, the cost is low, and the three are mixed and released, which can make up for The prevention and control effect can also reduce the cost of prevention and treatment." Jilin University of Agriculture researcher Qi Liansheng told reporters. Not only can a ball be released at the same time, it can release three kinds of Trichogram bees. For the special environment of paddy fields, the bee-keeping device has also been specially designed to be made of corn starch, which can be naturally degraded and naturally floated in water, and the hemisphere can be loaded at the bottom. Make sure that the buzzer is out of the bee hole, waterproof, flooded, and rainy, so that the red-eye bee can fly smoothly. The ball design is good for throwing, which greatly saves labor intensity. “The technology on display at the scene reflects a number of innovations and is in a leading position internationally.†Zhang Lisheng, chief expert of the National Key Research and Development Program’s Natural Enemy Insect Project, said that Trichogramma has been controlling corn borer for decades and has been in recent years. A new breakthrough, from the control of corn borer to the prevention and control of pests such as stem borer, expanded the control field of Trichogramma, realized the use of mixed bee and drone to improve the release effect and efficiency, and the treatment of Trichogramma It integrates with green pesticides, sexual attractants, rice paddy ducks, rice paddy crabs and other green prevention and control technologies to form a complete set of biological control solutions, avoiding the use of chemical pesticides at the source. Industrialized production achieves multiple technological breakthroughs On the same day, in the 5,000-acre paddy field in Wanchang Town, nearly 60 million Trichogramma were placed. How were these large numbers of Trichogramma corps cultivated? The reporters and representatives attended the agricultural modernization of Jilin Agricultural University. The Institute of Technology’s natural enemy insect production base will be explored. Zhang Junjie, deputy director of the Institute of Agricultural Modernization Technology of Jilin Agricultural University, said that the key part of the production of Trichogramma is to breed intermediate hosts as their carriers. The tussah eggs are commonly used intermediate hosts, which are relatively easy to raise and cost more. Low, these large eggs are suitable for the breeding of bee species such as Trichogramma, Trichogramma, and Trichogramma, but Trichogramma can not be parasitic in the tussah eggs, and can only be parasitized in the small eggs. To this end, Jilin Agricultural University Agricultural Modernization Technology Research Institute carried out key researches on the cultivation of Trichogramma in the rice moth egg factory, broke through the bottleneck of production technology, and realized the large-scale breeding of Trichogramma. On this basis, a new technology for the prevention and control of rice stem borer in large and small eggs breeding Trichogramma was developed. Not only can we mix and release bees, but the institute has also developed a multi-bee technology. Qi Liansheng told reporters that a multi-bee is referring to the species of Trichogramma and other Trichogramma in a tussah egg. Through this technological innovation, the dominant bee species such as Trichogramma and Trichogramma, which could not be bred by the tussah eggs, can be normally bred. The application of a multi-bee product in the field can increase the release of natural enemies and play a role in controlling a variety of pests. "In the prevention and control of corn caterpillar Trichogramma products, we have realized the application of diapause technology in the industrial production of Trichogramma in the tussah eggs for the first time in the world. The breakthrough of this technology makes the storage of Trichogramma The time has been extended to more than 90 days. The production in the first season has been produced several times a year, breaking through the seasonal restrictions on the production of Trichogramma and expanding the production scale by two to three times." Qi Liansheng said that Jilin Agricultural University's Agricultural Modernization Comprehensive Technology Research Institute has the capacity to produce 150 billion heads of Trichogramma. Since 2014, it has promoted 3 million mu of bio-defense area of ​​Trichogramma. In addition, the Institute has also developed a new product to control the soybean Trichogramma, control the Ginkgo biloba, and the new technology based on yacon as a host plant. The technology provides important technical reserves and support for biological control of major pests in agriculture and forestry. Green and effort will have more room for development As an important commodity grain base in China, Jilin Province plays an important role and strategic position in safeguarding national food security. In recent years, Jilin Province has vigorously promoted the technology of “control insects with insects†of Trichogramma, and the government has invested in the purchase of Trichogramma products for farmers, so that Trichogramma plays an increasingly important role in pest control. "The corn borer was the number one pest of corn. It is now less harmful, which is because it has been used for many years to release Trichogramma." Zhang Lisheng told reporters that the control of corn borer with Trichogramma has a long-lasting effect, and a virtuous cycle has been formed in the Northeast. . In addition to controlling corn borer, Trichogramma will also have a large space for the prevention and control of rice stem borer. "Red Tit bee control is especially suitable for areas where the pests occur in a rice producing area in Northeast China." Zhang Junjie introduced that rice is the second largest food crop in Jilin Province. The annual planting area is about 12 million mu. Huayu is the most important common pest in rice production in Jilin Province. Since 2014, Jilin Province has promoted the application of Trichogramma to control rice stem borer in many places. After long-term practice, the average control effect of this technology is about 70%, which greatly reduces the use of chemical pesticides and effectively improves the ecology. surroundings. Saving labor is another big advantage of Trichogramma. The reporter learned on the spot that the artificial sprayer can beat about 50 mu a day, artificially throwing a red-eye bee to put on a bee, and can operate 500 mu a day, while the drone is more efficient in placing the bee, and the delivery is more precise. Thousand acres. In addition, in terms of cost of prevention, the diffusion distance of Trichogramma is 15-20 meters, and only one spherical abalone can be placed on one acre field, and it is placed every 5-7 days in the beginning of adult mites. It can be placed three times in a row, and the cost per acre is 15 yuan, which is easily accepted by the growers. It is understood that in 2017, Jilin Province invested 6 million yuan to promote the application of 400,000 mu of rice. This year, it invested 15 million yuan to promote the prevention and control of T. chinensis on 1 million mu of rice.
