A kind of detection device for lychee stem borer and using method

Abstract

The invention relates to a detection device for lychee stem borers and a using method, belonging to the technical field of lychee stem borers detection, comprising a camera assembly, a detection assembly and a recording terminal device. A guide rod, the second guide rod is connected to a second circular ring, a plurality of detection holes are arranged on the second circular ring, and at least one indicator light is arranged on the outer side of each detection hole, and the indicator light is provided with at least two indication states, The indication state includes a state with lychee pedicle borers and a state without lychee pedicle borers; the present invention passes automatic detection through the whole process, and can perform all-round detection on lychees, solves the phenomenon that the occluded view area cannot be detected, and improves the detection data. Accuracy rate, but also conducive to the detection of personnel statistics. The present invention is small in size, can be easily carried to the site for sampling and all-round detection of lychees, and is beneficial to instructing farmers to spray pesticides.

Description

technical field [0001] The invention relates to the technical field of litchi stem borer detection, in particular to a detection device for litchi stem borer and a method for using the same. Background technique [0002] The lychee stem borer, also known as the lychee moth, belongs to the Lepidoptera family Lepidoptera. It is the most serious pest that damages lychees and longan fruits. It also damages tender stems, young leaves and flower spikes. The shoots or early-maturing varieties overwinter within the axis near the top of the flower spikes, and some studies suggest that there is no obvious overwintering phenomenon, but the litchi variety, climate, phenological period and other factors will affect the appearance time of the first generation of the insect. When the larvae hatch, they directly bore into the fruit from the bottom of the egg shell, resulting in a large number of fruit drop. When it damages the fruit at the near-mature stage, it only eats on the seed stalk. ...

Problems solved by technology

[0003] Nowadays, although technologies such as AR remote sensing technology and UAV remote sensing camera technology can capture certain images of litchi, there are still certain shortcomings in this type of technology, such as the blocked part cannot be photographed, which makes the staff work. I have to sample and test litchi until now. Due to the shortcomings of AR remote sensing technology and drone remote sensing camera technology, it is difficult to understand the actual insect situation. Often, sampling and testing are carried out on the spot. If it is only observed by human eyes to judge whether there are Pest infestation, low work efficiency

Nowadays, a large number of tests are performed by sampling lychees to the laboratory, and then using experimental instruments for testing. Using this method is inefficient
