Description

technical field [0001] The invention relates to a plant insecticide, in particular to a drug formula for controlling Bactrocera citrus. Background technique [0002] Bactrocera minax (Enderlein) belongs to Diptera (Diptera) Tephritidae (Tephritidae), is a destructive pest of citrus, the insect is mainly distributed in Hunan, Hubei, Sichuan, Chongqing, Yunnan, Guizhou and other regions in China . The insect has one generation per year, and it lays eggs in the citrus fruit. The larvae bore into the citrus fruit and feed on the pulp of the tangerine petals, causing the fruit to yellow and fall off before it is ripe, and lose its edible value. The fruit loss rate is about 20-30%. When the yield loss is serious, it can reach 70%-80% or even 100%. It has become the first insect pest in citrus production in my country, and the prevention and control situation is severe. The control methods of Bactrocera citrus include radiation sterility, agricultural physical control, chemical co...

Problems solved by technology

In the 1980s, the Institute of Atomic Energy of the Chinese Academy of Agricultural Sciences and the Institute of Atomic Energy of the Zhejiang Academy of Agricultural Sciences released radiation-sterile Bactrocera citrus in citrus orchards, and achieved good control effects. However, the prevention and control of radiation sterility requires government investment, which is very expensive. Its application has been affected; agricultural physical control includes picking maggots to eliminate insects, winter plowing to eliminate pupae, and covering film to kill insects. In the early stage and at the peak of occurrence, the pesticides are banned, and the soil is banned in the pupal stage, and the large-scale use of pesticides will cause environmental pollution, affect the health of humans and animals, pesticide residues and pest resistance, etc.
