Method for comprehensive prevention and control of bactrocera dorsalis and psyllids in citrus reticulata blanco orchard

Abstract

The invention belongs to the technical field of pest and disease prevention and control for fruit trees and particularly provides a method for comprehensive prevention and control of bactrocera dorsalis and psyllids in a citrus reticulata blanco orchard. The method includes physical prevention and control and chemical prevention and control. The physical prevention and control include: setting a net in height of 4-5m around the orchard, and circularly arranging a plant isolation protective belt outside the net; setting protective frames among rows of fruit trees in the orchard, hanging yellowor blue sticky trap boards on the protective frames, light traps are mounted above the protective frames, and traps with sex attractants are arranged above or below the protective frames. The chemicalprevention and control include: in a larval stage and an unearthed stage of bactrocera dorsalis, spraying 800-1000-fold solution of 50% phoxim to the ground; in a peak stage of adults, spraying mixedattractants to crowns of trees in the orchard and surrounding other trees; in a citrus yellow shoot general survey period and each germination period of citrus reticulata blanco, spraying a psyllid preventing agent to front and back surfaces of leaves of citrus reticulata blanco. By means of physical prevention and control, chemical prevention and control, biological prevention and control and the like, comprehensive prevention and control of bactrocera dorsalis and psyllids can be realized, the two types of major lethal pests to citrus reticulata blanco can be effectively prevented and controlled, and yield increasing of citrus reticulata blanco is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of fruit tree diseases and insect pests, and specifically provides a method for comprehensive prevention and control of Bactrocera dorsalis and psyllids in citrus orchards. Background technique [0002] Citrus citrus fruit orchards belong to Diptera, Diptera, Tephritidae Trypetidae, and subfamily Dacinae. It is one of the important pests in the production of Wo citrus. It turns yellow and falls off before it is ripe, which seriously affects the yield and quality of various fruits and vegetables such as tangerines. Bactrocera dorsalis has a very strong viability, and the larvae eat the fruit in the fruit. It is very difficult to control it. It is necessary to comprehensively control B. dorsalis by means of physical control and chemical control. [0003] The orchard psyllid is also one of the important pests in the production of Wogan, and it is the only vector insect that transmits ...
