Cydiapomonella (L.) is a member of the order Lepidoptera. It is one of the most serious pod pests in the world and it is a national and international quarantine target. Over the years, it has been the main reason for countries in the world to limit the export of fruit from China. Its characteristics, first, miscellaneous eating habits, larvae and fruit damage, resulting in a large number of fruit drop, after the second generation of larvae damage can cause the center of the fruit rotten, seriously reducing its commercial nature; Second, many victims, in addition to harm the apple in my county outside Apple pears, pears, peaches, apricots, sand berries, etc. are the main targets of its harm; Third, resistance, adaptability. According to the survey, under the weather conditions in our county, it is entirely safe for wintering. Fourth, the harm is large, the loss is heavy, and the control of blockade is also very difficult. Moreover, it has the ability to migrate, and the larvae can be transported with fruit and spread over long distances. very fast. Its characteristics determine the difficulty and complexity of the control of codling moths. Based on our years of experience in research and demonstration, we summarized the following comprehensive prevention and control technologies:
First, the quarantine measures are mainly the use of legal means to block the spread of the codling moth. (1) Strengthen the market quarantine and implement the market access system. That is, a plant quarantine office is set up in the farmer's wholesale market, and quarantine inspections of fruits entering and exiting the county are made at any time. Circumstances of listing pests and fruits are strictly prohibited, and the detected fruit with insects is harmlessly disposed of or destroyed by law. (2) Intensify transport quarantine, and strictly control fruit exports. Strictly quarantine the fruit, packaging, and transportation tools that are brought out to prevent the further spread of the codling moth. (3) Strengthen the quarantine at the place of production and do a good job of source control.
Second, biological comprehensive prevention measures
1, trunk scraping old skin, lime brush white requirements: in the year after the temperature reached -10 °C until March 15 next year, the age of 10 years old fruit tree skin scraping clean, while lime white, clean orchards. The height of brushing is based on the height of the old skin of the fruit tree, generally more than 1 meter. The old bark after cleaning should be burned or buried deeply.
2, the use of frequency vibration type insecticidal lamp trapping adult requirements: the end of April to the end of September, set up in the orchard insecticidal lamp, set up every 20 acres. The on/off time of the light is turned on every day after dark, and it is turned off after dawn, and the insects in the insect receiving bag are promptly removed.
3. Application of attractants to kill males and prevent mating, so as to achieve the effect of insect control: Beginning in late April and ending in the end of September, set up traps 3-4 per acre orchard, add water in time, and replace them every 60 days. Lures.
4. Requirements and time for larvae and straw rings to trap and kill overwintering larvae: From late July to early August, use wheat straw, straw, corn stalks, broken sacks, etc. to make a circle on the main pole or trunk bifurcation. Trapping the overwintering larvae from November to the end of February of the following year, combined scraping of the bark, disintegrating the grass rings and burning them to destroy the overwintering larvae.
5, removal of pest fruit requirements and time: fruit growing season, especially after July, often check the orchard, timely picking up the fruit, deep-buried or fermented. Elimination of larvae which have not been de-fruited; before the fruits are brought into the pit, they must be carefully selected and picked up to prevent the larvae from spreading into the pits as winter fruits or consigned fruit to spread.
