Trichogramma Technology for Preventing Corn Borer
2023-09-21 08:08:05
At present, it has entered the period of release of Trichogramma to control corn borer. The release of Trichogramma can significantly control the damage of corn borer. The method is simple, and it has continuous control effect. It is one of the green prevention and control measures in the corn field.
First, the main advantages
1, easy to use: the release of Trichogramma method is simple, you only need to hang the bee card on the plants, both men and women can operate, no risk of poisoning.
2, save time and labor: release of Trichogramma only need to hang 8 to 10 bee cards per mu, fast operation, adults can hang cards about half an average of about half an individual, its efficiency is much higher than the spray pesticide or sprinkle particles Agent.
3, no pesticide residues: Trichogramma is the natural enemy of corn borer, release Trichogramma will not cause environmental pollution and pesticide residues, can better protect the quality of fresh corn.
4. The effect of continuous pest control is good: Trichogramma can use self-propagation of pest eggs, compared with the use of chemical pesticides, the release of Trichogramma better control of corn borer.
Second, after using the technology to enter the peak period of laying eggs, the first bee feeding time is expected to be around July 5, with 8 to 10 bee cards per acre, about 10,000 Trichogramma released bee. When placing the bee, the bee card is hung evenly under the leaves of the middle corn or under the leaves near the cob. After the first bee was released, the bees were released again after an interval of 5 days. Each corn borer generation needs to lay the bees 2 or 3 times. First determine the release of bee stings, and then be sure to put the bee, the bee professional team put the bee. The determination of the release of bee stings: from the 20th point on the ground to the first one to put the bee sting, from the first one to put the bee sting number 40 to the second bee sting, and so on. Put the confirmation of the bee point: Take the 13m from the place where the bee is placed and put it inward for the first place. From the first point of the bee, go inward again for 26m to put the second bee, and so on. After selecting the bees, place the bee card with a toothpick on the back of the blade at the middle of the bee-bearing corn plant, and bend the blade at a distance of 1/3 from the base of the blade. When hanging cards, try to choose before dusk so as not to affect the field life of Trichogramma and reduce the pest control effect.
Third, the release of Trichogramma attention
1. Large scale contiguous bee can improve comprehensive control effect Trichogramma and corn borer can both fly at short distance. The release of Trichogramma by large area can effectively reduce the base number of corn borer in the bee-keeping area and improve the long-term control of corn borer damage. Effect.
2, to avoid spraying chemical pesticides Trichogramma and other natural enemies insects are highly sensitive to pesticides, spraying pesticides during the release of bees will kill a large number of natural enemies, reduce the control of natural enemies on pests.
