Description

fruit fly trap

technical field

The utility model relates to a device for trapping and killing insects, which belongs to the field of pest control.

Background technique

Fruit flies belong to the family Diptera Drosophila and Tephritidae insects. Fruit flies are widely distributed and can seriously damage a variety of fruits and vegetables, such as bayberry, mango, papaya, cucumber, etc., causing major economic losses to growers. Many fruit flies are the objects of internal and external quarantine, and they do serious damage at the stage when chemical pesticides cannot be applied, which affects postpartum storage, transportation and preservation. For example, before the hard seeds of bayberry fruit are colored, fruit flies occur less and do not cause harm to it. But after the red bayberry enters the mature period, the fruit becomes soft, the fragrance is strong, and the insect fruit rate reaches more than 60%, which seriously affects the quality and output of the red bayberry, and postpartum storage and fresh-keeping. Fruit fly control is very difficult, mainly because 1) the reproduction rate is high, such as a female of Mediterranean fruit fly can reach 21.5 billion after three generations of reproduction, and the time only needs 60 days. The fruit fly has a short generation period and a fast reproduction speed; 2) the pests have strong resistance to pesticides; 3) most of them are low-light pests; 4) they are mostly omnivorous, and the harmful plant species and hosts are various. wide, and the harm of changing the master is frequent. 5) The developmental temperature of fruit flies and fruit flies is low. The starting temperature of C. medfly development is 12°C, and the effective accumulated temperature for one generation is 622 degrees per day. If the temperature is between 16-32°C, the relative humidity is between 75%-85%. Fruit flies exist widely in nature, and when the temperature exceeds 10°C, the activities of fruit fly adults can be seen. Under the conditions of temperature 21-25°C and humidity 75%-85%, the duration of one generation is only 4-7 days. In the field, the generations overlap, and it is difficult to divide the algebra, and each insect state coexists at the same time. 6) Strong flying ability, the flight distance of Ceratitis medfly reaches 3212 kilometers.

Since fruit flies are always harmful at the mature stage, this is generally the period when chemical pesticides should not be used, so other non-chemical pesticide control methods must be sought. At present, in addition to ecological control such as weeding in orchards, physiological fruit drop before fruit ripening, and rotten fruit falling to the ground during the mature harvest period, fruit fly control is completely dependent on chemical pesticides. However, spraying with pesticides kills the fruit flies, but also poisons the natural enemies and leaves pesticide residues. Since it has entered the mature harvesting season and the ripening time is short, spraying pesticides will directly affect the safety of the fruit.

Semiochemical control technology has the advantages of high selectivity, extreme sensitivity, no direct contact with plants or fruits, completely harmless to the environment, and no drug resistance problems. Therefore, the development of semiochemical trapping with high attractant activity is an important prerequisite for ensuring the production of safe agricultural products, protecting the agricultural ecosystem and the environment-friendly control technology of natural enemies. In the trapping and killing technology, in addition to the activity of the attractant, the efficiency of the trap is also quite critical.

In recent years, many fruit fly traps have been invented, including multiple traps for fruit flies to escape, such as "fly trap" (patent application number: 93108576.4), "mosquito trap" (patent application number : 99225349.7), fruit fly trap bottle (patent application number: 02249655.6), "anti-escape device for fruit fly trap" (patent application number: 03242521.x), "fruit fly trap" (patent application number 200510200197.4), etc. .

These existing technical scheme designs that can be used for trapping devices for fruit flies consider how to utilize attractants to lure fruit flies into the traps and how to prevent the fruit flies entering the traps from escaping, but the device and the anti-escape The designs are all more complicated and the cost is higher, which is unfavorable for popularizing and using them in rural areas.
