Description

Port medical science medium biological monitoring is with luring fly cage

Technical Field

The utility model belongs to the technical field of fly catching devices, and particularly relates to a fly attracting cage for port medical medium biological monitoring.

Background

The medical quarantine and investigation of the port is an important link of port health quarantine work, and is an important gate for keeping national security. The capturing and monitoring work of the disease-causing insects is a key content of national port and customs health quarantine work, and the adult flies are common disease-causing insects which can carry a plurality of pathogenic microorganisms to be transmitted so as to endanger human health, so that the capturing and detecting of the adult flies is particularly important.

When capturing adult flies, a net trapping method and a cage trapping method are more commonly used. The net catching method is to catch adult flies by using a net made of small and medium-sized white basket bottom yarns, and put the fly into a poison bottle and then put the fly into a laboratory for identification and detection, and the net catching method is low in efficiency, tedious in catching and long in time consumption. The fly trapping cage trapping method generally adopts an outer net cover and an inner net cover, wherein the inner net cover is arranged in the outer net cover, a cavity is formed between the outer net cover and the inner net cover, the inner net cover is integrally in a conical structure with a small bottom and a large top, a bait disc is arranged at the bottom of the inner net cover, fish viscera and rotten fruits are filled in the bait disc to trap flies, and a hook is arranged at the top of the outer net cover to hang. Because the fly flies through the up-and-down swinging wings, according to stress analysis, the fly cannot fly in parallel or downwards but only can fly upwards or obliquely upwards, after the fly is attracted by the bait and enters the bait tray for feeding, the fly flies upwards and enter the outer net through the upper thin opening of the conical inner net cover, and cannot fly out, so that the fly is captured. However, the existing fly attracting cage has the following problems: firstly, the existing fly attracting cage structure generally has complicated structure, is very inconvenient to disassemble and assemble, and when the flies are taken out, the flies need to be taken out by separating the inner net cover from the outer net cover and then reinstalled, so that the use is very complicated, and meanwhile, the cleaning and maintenance are also very troublesome; secondly, when the fly attracting cage is subjected to field suspension operation, the fly attracting cage is often overturned due to wind and rain conditions, and the bait is poured out or the net cover is damaged due to the attack of birds, and naturally, the fly attracting cage which can be directly placed on the ground is also available, but a bait disc of the fly attracting cage is directly placed on the ground and is easily damaged by small animals such as mice, badgers and the like, so that the working stability of the device is poor; thirdly, when the bait is placed for a long time, dehydration and drying occur in the air, so that flies cannot be effectively attracted, and the fly catching effect is poor.
