Biological prevention and control method utilizing cucumis melo as trap plant to prevent and control scale insects of citrus orchard

Abstract

The invention relates to the technical field of agriculture, in particular to a biological prevention and control method utilizing cucumis melo as a trap plant to prevent and control scale insects ofa citrus orchard. The method includes following steps: accelerating germination of cucumis melo, and transplanting into the citrus orchard after greenhouse seedling culture; in the citrus orchard, foran area where cucumis melo needs to be cultivated, ploughing, sufficiently watering, covering with thin films, and cultivating cucumis melo around and between rows of the citrus orchard area, managing water and fertilizer according to those of the citrus orchard, and managing cultivation according to cucumis melo planting technology; utilizing cucumis melo to attract the scale insects, and when damaged area of whole-plant fruits, leaves and vines of cucumis melo exceeds four fifth, bagging whole damaged cucumis melo plants, putting the same onto an open cement floor for exposure to the sun for several days, and burning up. The scale insects of the citrus orchard are attracted by utilizing cucumis melo and then treated in a centralized manner, so that the number of nymphs is reduced effectively, adults and eggs difficult to prevent and control are taken into consideration, and a new way is provided for efficient prevention and control of citrus scale insects.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a biological control method for preventing and controlling scale insects in citrus orchards by using pear melon as a trapping plant. Background technique [0002] At present, scale insects are a general term for Homoptera and Scale suborder insects, and are one of the most common and serious pests in citrus orchards. There are many kinds of them, and most of them are harmful to the branches, leaves, petioles, fruits, fruit stalks and other aerial parts of plants. For a long time, the control of scale insects has mainly relied on chemical pesticides, mainly nymphs. Because of the wax shells, wax powder, and wax filaments outside the adult body, there is no effective pesticide control. Once scale insects occur in large numbers, they all exist in a multi-worm state, and it is difficult for pesticides to achieve the purpose of eradicating them. Biological control of scale ins...

Problems solved by technology

Good control effect but strict requirements on the field environment, no other insecticides or fungicides can be sprayed in the field during the growth period

However, the research and development costs of these technical methods are high, time-consuming and labor-intensive, and the field application has great limitations.
