On July 30, the reporter learned that in order to effectively control the American white moth, the forest defense station of the Luohe Forestry Bureau is currently working with the Forestry Bureau of Yuanhui District to release Zhou's small bees. It is reported that this control is another centralized control action of the American white moth organized by Luohe City after the control of aircraft spraying, and it is a supplement to the control of key areas that are not suitable for flight prevention, and it is expected to release 5 million Zhou's wasps.
According to reports, the American white moth, also known as the American lamp moth and autumn moth, is extremely harmful to fruit trees and ornamental trees, especially broad-leaved trees. Summer into the peak of the activity of the American white moth, Luohe City's warm and humid climate is very suitable for the growth of the American white moth, if not timely prevention and control, it is very easy to cause large-scale reproduction of the American white moth, causing immeasurable losses to agriculture and forestry.
Zhou's wasp, belonging to the genus Ofcher bees of the family Ji Bee, is a dominant natural enemy in the current control of the epidemic of the American white moth in China, with high parasitic rate and strong fertility, and is the natural enemy of forestry pests such as the American white moth, which can stab its egg layer into the pupae of the American white moth and other pests, and develop and grow in the pupa, suck all the nutrients in the parasitic pupa to cause its death, which can effectively reduce the density of the mouth of the American white moth. Biological predator control is safe and environmentally friendly, non-toxic to people, livestock and plants, does not pollute the environment, pests will not produce resistance, and can receive long-term pest control effects.
It is understood that a total of 5 million Zhou's small bees were released this time. This control is also another centralized control action of the American white moth organized by Luohe City after the control of aircraft spraying, which is a supplement to the prevention and control of key areas that are not suitable for flight control.
