Automatic and continuous aphidiidae releasing device

Abstract

The invention relates to the technical field of agriculture pest biological prevention and control devices, in particular to an automatic and continuous aphidiidae releasing device. The automatic and continuous aphidiidae releasing device comprises a supporting frame, a releasing hole formed in the supporting frame, a fixing ring, a 60-mesh gauze element and a 40-mesh gauze element, wherein the fixing ring is arranged in the release hole in a sleeved mode, the 60-mesh gauze element is fixed to the supporting frame, and the 40-mesh gauze element is arranged on the top face of the release hole. The 60-mesh gauze element is fixedly connected with the supporting frame through thin ropes. The 40-mesh gauze element is fixedly connected with the release hole through the fixing ring. By use of the automatic and continuous aphidiidae releasing device, eclosion of aphidiidae from stiff aphids is continuously carried out, the aphidiidae automatically enter a smoke yield to search for myzus persicae for parasitism, the parasitism rate can be improved to be 90-100%, manpower and material resources can be greatly saved, the prevention and control functions can be automatically and continuously achieved, and the aim of prevention and control over myzus persicae and aphid transmission viral diseases is achieved with a small quantity of pesticides or without pesticides.

Description

technical field [0001] The invention relates to the technical field of biological control equipment for agricultural pests, in particular to an automatic and sustained release device for aphids. Background technique [0002] Aphids aphids is an important parasitic natural enemy of aphids, and they follow and lag in nature. Therefore, the control of fulminant aphids still requires artificial breeding to release aphids. [0003] At present, two methods are mainly used to deal with it. (1) Build small sheds in the tobacco field. Each small shed is placed with 30 pots and requires a land area of ​​10 square meters. Building a small shed is time-consuming, costly, difficult to manage, and cannot be automated. It is difficult to control and count the bees continuously, and the device is inconvenient to recycle. If it is not economical to use small-area fields, and the seal is not tight, aphids often invade the tobacco field; (2) The bee collection bag is released into bees, The b...

[0003] At present, two methods are mainly used to deal with it. (1) Build small sheds in the tobacco field. Each small shed is placed with 30 pots and requires a land area of ​​10 square meters. Building a small shed is time-consuming, costly, difficult to manage, and cannot be automated. It is difficult to control and count the bees continuously, and the device is inconvenient to recycle. If it is not economical to use small-area fields, and the seal is not tight, aphids often invade the tobacco field; (2) The bee collection bag is released into bees, The bees collected by artificial harvesting or bee suction devices are transported to the smoke field for release, and the mortality rate of bees collected by manual bee collection or bee suction devices is high. One collection of bees cannot meet the release requirements of large-scale tobacco fields. Due to the short life span of adult bees, the adult bees There will also be a large number of deaths during transportation, and even if they survive, the spawning parasitism rate is greatly reduced
