Description
Technical Field
The invention relates to the technical field of agricultural prevention and control, in particular to a method for preventing and controlling citrus fruit flies.
Background
Bactrocera dorsalis (Bactrocera dorsalis) Hendel is Diptera of Diptera, Trypetidae of Bactroceraceae, Dacinae of subfamily Oligochaeta. The citrus fruit fly larvae eat the fruits and are harmful, so that the fruits are usually unripe and yellow and fall off first, and the yield and the quality are seriously influenced. Except for oranges, the fruit can also be more than 250 kinds of fruits such as mango, guava, kiwi fruit, carambola, loquat, watermelon, towel gourd, balsam pear, pepper, tomato, eggplant and the like. Adults can lay eggs in host fruits for multiple times, larvae take flesh from the fruits and develop and grow, the larvae grow out of the fruits after being mature, enter soil and pupate, and the adults emerge in the soil. After the fruit of the crop is damaged by the bactrocera dorsalis larvae, fruit drop or fruit loss of economic value can be caused, which leads to serious yield reduction and fruit quality reduction, and even causes the crop to be in no harvest.
The citrus fruit fly imago has long service life, long spawning period and long pre-spawning period. In south China, because of high temperature and rain, high temperature accumulation all year round and evergreen all year round, 6-7 generations can occur all year round, and the field generations are overlapped, so that adults of 2-3 generations can survive at the same time. Except for winter, the quantity of the citrus fruit fly imagoes does not have obvious peak-valley change in spring, summer and autumn, so the traditional mode of forecasting the occurrence peak of the citrus fruit fly according to generation prediction according to field survey and adopting corresponding prevention and control measures has poor effect in south China. The beginning of the fruiting period of bactrocera dorsalis in most areas in south China is 3 to 4, adults gradually increase from the middle and the last of 5 months, and the peak is reached after 7 months, but certain differences exist in different ecological areas. However, at present, no method for preventing and controlling the harm of bactrocera dorsalis by predicting and forecasting bactrocera dorsalis in different areas exists, so that the field prevention and control work of the bactrocera dorsalis is difficult to effectively carry out.
