Recommended product: Sexton ® Drosophila bait
Sexton ® The Drosophila bait and kill set is a high-tech product designed to lure Drosophila melanogaster and Drosophila melanogaster, which are harmful to soft skinned fruits such as blueberries, cherries, grapes and raspberries. Through the pheromones emitted by the special formula bait, it continuously attracts Drosophila to approach and contact the bait bag in an open environment, so as to achieve the goal of continuously reducing the population base. Sexton ® The Drosophila bait is different from the bait bottle. It achieves "internal" lure and "external" killing instead of "internal" lure and "internal" killing, and its efficiency is far higher than that of ordinary bait and kill products. Moreover, the lure radius of this product is no more than 5 meters, which will not attract far away fruit flies to harm, and can effectively protect the orchard.

working principle
1. The sexton Drosophila bait contained in the bag strongly attracts male and female adults of Drosophila to approach; 2. After Drosophila adults are attracted by the smell, they stay and crawl on the surface of the bait bag, and very few enter the bait bag; 3. When the adult crawls on the surface of the bait bag, it contacts the waterproof drug film covered on the surface of the bait bag, then its activity decreases and it dies slowly.

Product advantages
1. Duration: about 20 days;  
2. Specificity: the attractant formula is unique, only for Drosophila melanogaster and Drosophila melanogaster, and does not harm natural enemies and beneficial insects;  
3. High efficiency: the area of the bait bag is much larger than the hole on the trap, and the Drosophila does not need to "enter" the bait bag, but only needs to contact the surface of the bait bag to die;  
4. No drug resistance, no blind area: the smell released by the inducer permeates all corners of the park, and there is no drug blind area and drug resistance;  
5. Green and safe: the inducer bag does not touch the fruit surface, and there is no pesticide residue; The medicine will not disperse and will not pollute the environment.

Usage method
After mixing the Drosophila attractant with water in the ratio of 1:3, inject 400ml into the attractant bag per bag, hang 10-30 bags per mu on the branches of fruit trees 2 / 3 above the ground; The validity period is about 20 days.
It is usually used seven days before fruit ripening, but in principle, it can be used as long as Drosophila is detected, and the number of inducers or inducer bags can be supplemented as needed.

Three optional field application schemes:
① Whole process prevention and control (recommended): minimize the population base of fruit flies in the orchard. The commercial fruit should be used 7 days before harvesting. It is recommended to use 10-20 points per mu and replace the inducer every 15-18 days.
② Basic prevention and control: when the number of insects was low in previous years, it was used in conjunction with other prevention and control measures to help reduce the harm of fruit flies. It is recommended to use 10-15 points per mu for 1-2 times.
③ Emergency prevention and control: Drosophila damage has occurred in the field, which is used to quickly reduce the population base and recover part of the losses. It is recommended to use 20-30 points per mu.

Key points of use
1. Pheromone control technology is greatly affected by the environment when it is used in a small area, and the control effect is not stable enough, so it is recommended to use it in large areas;
2. 1:2 dilution in rainy areas and 1:3 dilution in dry areas. In case of continuous high temperature and dry weather after use, it may be necessary to supplement the medicine;
3. Prevention and control in advance, even if the harm to the orchard in the early stage is light, we should still pay attention to the protection of early maturing varieties;
4. For orchards with a harvesting period of more than 20 days, new attractants should be added 15-18 days later to continuously lure Drosophila and reduce the number of insects;
5. It is recommended to monitor the number of Drosophila from fruit setting to the end of harvesting;
6. When used for the first time, it should be used together with other agricultural and physical prevention and control measures. If necessary, it is still necessary to use chemicals scientifically to control and reduce the insect population.

Matters needing attention
1. Store in a cool place away from light. Please use it up as soon as possible after opening the lid to prevent the product from losing efficacy due to the smell of attractant;
2. The surface of the inducer bag of this product needs to be covered with a drug film (optional). Gloves should be worn during use. It is not allowed to directly contact the surface of the inducer bag with bare skin. The attractant smell is strong, and some sensitive people should wear masks when using it;
3. In case of continuous high-temperature weather, the medication cycle should be shortened as appropriate, about 15-20 days;
4. Do not let children eat the bait by mistake or touch the surface of the bait bag;
5. Please do not discard the bait bag after use, please put it into the garbage can.

Fruit fly pests
Drosophila, Diptera, Drosophilidae
Drosophila is widely found in temperate and tropical climates around the world. Because its staple food is yeast, and rotten fruit is prone to yeast, it can be found in human habitats such as gardens and vegetable markets. The Drosophila melanogaster and Drosophila melanogaster have the greatest impact on our agricultural production, especially Drosophila melanogaster.

Host range: Drosophila melanogaster has a wide range of host crops. The known hosts involve more than 60 kinds of fruits in 18 families, mainly including bananas, kiwifruit, persimmons, figs, strawberries, cherries, plums, nectarines, pears, blackberries, raspberries, blueberries, grapes and tomatoes. Drosophila melanogaster is saprophytic and feeds on rotten fruits.

Distribution: it is widely distributed in temperate and tropical climate regions of the world.
Harm symptoms: due to the different structures of ovipositors, the harm modes of the two Drosophila species are different. The ovipositor of the female Drosophila melanogaster is hard and serrated. It can directly lay eggs in immature, near mature and fully mature cherry, peach, European plum, grape, strawberry, raspberry, blueberry, persimmon, tomato and other soft skinned fruits. The larvae feed in the fruits. The host crops of Drosophila melanogaster are extensive. The known hosts involve more than 60 fruits of 18 families, mainly including bananas, kiwifruit, persimmon, figs, strawberries, cherries, plums, nectarines, pears, blackberries, raspberries, blueberries, grapes and tomatoes. The larvae mainly feed on fruit pulp inside the fruit. The damaged fruit quickly begins to rot around the feeding point, and causes secondary infection of fungi, bacteria or other diseases, accelerating the decay of the fruit.
Drosophila melanogaster is saprophytic and feeds on rotten fruits. Since Drosophila melanogaster has no zigzag ovipositor, it can only harm fully mature and rotten fruits. From this point of view, Drosophila melanogaster has a greater impact on the commercialization of fruits. It can harm from the fruiting stage, but Drosophila melanogaster can only harm at the later stage of fruit maturation.

Occurrence law
Drosophila melanogaster can reproduce about 13 generations a year, and the fastest time is 12 days to complete the life cycle of one generation. The lifespan of adults varies greatly between different seasons and generations. The lifespan is mainly affected by temperature. It survives for 3 weeks to 10 months, and some can live for more than 300 days. It mainly overwinters as adults, and sometimes as larvae and pupae. In spring, when the temperature is around 10 ℃, the adults start to move, laying 1-3 eggs each time, and each adult produces nearly 400 eggs. The eggs hatch into larvae in 12-72 hours under normal temperature. The larvae feed in the fruit for 3-13 days, grow, mature and pupate. The pupae emerge into adults after 1-5 days.
Drosophila melanogaster has about 11 generations a year. It overwinters as a pupa in the depth of 1-3cm in the soil, rotten fruit or fruit shell. At the end of February and early March of the second year, when the temperature is about 15 ℃ and the ground temperature is 5 ℃, the adult begins to appear. When the temperature is stable at about 20 ℃ and the ground temperature is stable at about 15 ℃, the insect population increases. The adult begins to lay eggs on the fruit in late May. The peak period of egg laying is in the first and middle of June. After hatching, the larvae eat in the fruit for 5-6 days, After aging, they shed fruit and pupate. After the pupae emerge, they continue to lay eggs and reproduce the next generation, with overlapping generations. After the end of September, the number of Drosophila adults gradually decreased with the decrease of temperature. From the end of October to the beginning of November, the adults disappeared in the field and overwintered in the overwintering place as pupae.
 
Distinguishing features
Drosophila melanogaster is small, with a length of 3 ~ 4mm. There are some differences between Drosophila melanogaster and Drosophila melanogaster in morphology. Drosophila melanogaster, also known as Drosophila Suzuki, has black spots on the top corner of the leading edge of its wings, but Drosophila melanogaster does not; The first and second tarsal segments of the forefoot of the male flies of Drosophila melanogaster have a cluster of sexual combs respectively, and only the first tarsal segment of Drosophila melanogaster has a black sexual comb; There are uninterrupted black bands on the back of the ventral segment of the female Drosophila melanogaster, and black rings on the ventral end. There are 5 obvious uninterrupted black bands on the back of the abdomen of the female Drosophila melanogaster. The ovipositor of the female Drosophila melanogaster is obviously black zigzag, and the ovipositor of the female Drosophila melanogaster is non black zigzag.
