In order to keep abreast of the population dynamics of fruit fly, the biological and ecological characteristics of Bactrocera dorsalis should be monitored in the main producing areas of the fruit by setting up adult test sites, field investigations, and collecting fruit and fruit. Agricultural measures The same kind of fruit cultivation: In the same area as much as possible to plant the same species or fruit varieties mature to interrupt the orange fruit fly fruit chain. Orchard plowing: After harvesting the fruit, combined with the winter garden, plowing the garden soil once to kill some of the earthworms in the soil. Orchard cleaning: In the affected orchard, the fruit should be removed in a timely manner during the fruit drop period, once every 3 days during the fruit drop, and every fruitful period from the end of the fruit drop to the end of the fruit drop period. At the same time, there should be timely removal of green fruit and ripe fruit on the tree. The larvae of Bactrocera dorsalis can be killed by simple methods such as deep burial, flooding and incineration. The fruit bagging: According to different fruit varieties, use the corresponding fruit bag for fruit bagging, the bagging time should be based on the growth period of different fruit varieties and the local fruit planting situation, combined with the actual situation of the orange fruit fly, the red meat honey pomelo The bagging is usually started after the fruiting period. Experiments have shown that bagging is effective in preventing the infestation of Bactrocera dorsalis and the control effect can reach or approach 100%. Physical method Attractant trapping and attractant improvement: Adult attractants of the fruit fly, Bactrocera dorsalis, and other special attractants such as fly-catching ethers can also be used to supplement the habits of feeding the nutrient after copulation with Bactrocera dorsalis and using homemade proteins such as hydrolyzed protein. Poison baits trap male and female adults. The use of brown sugar, molasses and other mixed organophosphorus insecticides induced the fruit fly of Bactrocera dorsalis after 24 hours. chemical method At present, the effective chemical agents for Bactrocera dorsalis are mainly organic phosphorus and pyrethroid lipids, 40% of omethoate and other single agents and phoxim 1:9 mixture and phoximidine 1:1 mixture. The agent has a higher toxicity against B. dorsalis. In addition, the use of avermectin 1.8% EC 2000 times the average control effect of 85.1%, Kung Fu 2.5% EC control effect of 74.6%, dichlorvos 80% EC 1000 times control 71.1%, high efficiency cyflumethrin 4.5% EC 2000 times The liquid control effect was 54.4%, and the dipterex 80% soluble powder 1000 times liquid control effect was 40.4%. Technical Summary Prevention and control of Bactrocera dorsalis should be based on the tactics of killing males and fruits, fruit bagging and other agricultural measures, combined with chemical control, and making full use of natural enemies and biological pesticides that do not pollute the environment for comprehensive prevention and control.
