Description
Technical Field
The utility model relates to the field of pest killing, in particular to a pest killing effect verification device.
Background
In agriculture and tobacco industry, for example, storage of foodstuffs and tobacco leaves is faced with insect pest problems.
In the tobacco industry, pests include mainly tobacco beetles, commonly referred to as cigarette beetles, cigar beetles, or tobacco beetles. The tobacco pests also include tobacco leaf rollers, which are tobacco moths of the family borer. These pests attack the tobacco material, severely affecting the final product. In the tobacco industry, considerable amounts of funds are spent in order to kill tobacco insects to exterminate these pests. The quality of tobacco leaves is critical to the quality of the final product at the stage of entering the tobacco industry production line. If the tobacco leaves are infested with tobacco beetles or tobacco leaf rollers, the tobacco leaves are not only affected by themselves infested with such pests, but also by-products of the pests. In summary, in the case of insect pests of tobacco beetles, the overall quality of the tobacco leaves is severely reduced. In addition, the insect-damaged tobacco leaves present a potential risk of contaminating other tobacco leaves that are still of good quality. Contamination can occur during storage of tobacco leaves, during the manufacturing process, and shipment into retail end products, potentially reaching end consumers. When insect infestation develops, it can cause significant disruption to the manufacturing process, as the tobacco inventory needs to be discarded, and the shipping carriers, storage areas, and production lines need to be cleaned and sterilized. Therefore, pest control and pest control are very important for tobacco warehouses where tobacco is stored. In addition, there is a need to constantly monitor insect conditions in tobacco warehouses in order to control insect pests in a timely manner.
At present, the main measures adopted in warehouse control of tobacco storage pests in China are chemical control, wherein the chemical control comprises fumigating with a fumigant and the use of a protective agent, the protective agent is very common in the control of grain storage pests, and common protective agents include insect phosphorus prevention, triamcinolone acetonide, kaiser and grain protection. Regarding the study of tobacco protectants, H.J. Benezet et al have studied the virulence of 11 insecticides (including 4 organophosphates, 6 pyrethroids and nicotine) to tobacco beetles, with pyrethroid insecticides being more virulent.
In the prior art, the effect of tobacco warehouse after control adopts tobacco to add the trapper to monitor insecticidal effect. For example, the trap is manufactured into the artificial tobacco beetle sex pheromone with high pertinence by a technology of artificial synthesis aiming at the principle that sex pheromone released by female beetle adults of tobacco beetles attracts male beetles. Such products are highly consistent with the chemical structure of natural sex pheromones. The bait has the advantages that the bait has a good attracting effect on male adults of tobacco beetles and tobacco powder borers, can be compared with natural sex pheromones, has high sensitivity, is matched with viscose boards for use, has a good trapping effect, and is very suitable for monitoring insect conditions of the tobacco beetles and the tobacco powder borers.
Therefore, the current method for killing insects and monitoring the insecticidal effect is to spray medicines in one bin or one area in a warehouse, and then monitor the insecticidal effect by matching with grains or tobacco and a trap. This inability to quickly verify the effectiveness of the protectant against insects and the need to spray the protectant one bin or zone at a time requires significant protectant and labor costs.
