Description

Technical Field

[0001] This invention relates to the field of cockroach trapping, and more particularly to a cockroach attractant and its application. Background Technology

[0002] Cockroaches prefer warm, humid places with abundant food and many crevices. They are extremely resilient and reproduce rapidly, making them difficult to eradicate completely and causing significant disruption to people's lives. In recent years, the number of cockroach bait and trap products has increased rapidly. These products are effective at eliminating cockroaches and are suitable for use in areas such as kitchens and restaurants where aerosol or spray insecticides are not suitable. The main products for trapping and killing cockroaches include cockroach baits and cockroach traps. These products contain attractants that draw cockroaches closer, causing them to ingest the poison or become stuck on the trap and eventually die.

[0003] However, existing cockroach baits suffer from insufficient attractancy. This is especially true for formulations with specific requirements regarding color and consistency, such as transparent and white cockroach gel baits. Most substances that attract cockroaches cannot be used in these cases. Therefore, developing low-dosage, transparent compounds is of significant value for upgrading cockroach bait products.

[0004] Therefore, it is urgent to develop a cockroach attractant that has a significant attraction effect on cockroaches and can be added to various cockroach-killing products. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a cockroach attractant and its application. The cockroach attractant of this invention has a significant attractant effect on cockroaches, requires extremely low dosage, has a mild odor, is safe and non-irritating, can be added to various cockroach-killing products, has wide applications, high cost-effectiveness, and high economic value.

[0105] Cockroach traps containing cockroach attractants were placed in appropriate locations within the market. The number of German cockroaches caught within a certain time period was counted to test their attractiveness to wild German cockroaches in the market. The cockroach traps were placed side-by-side in each location, and the order of the three traps was reversed each time a location was changed. The allocation examples for Examples 2, 7, and 8 and Comparative Example 1 are shown in Table 6.

[0107]

[0108]

[0109] Test Example 5

[0110] This test example tested the performance of the white gel bait prepared according to Example 2 of the present invention (test example). The components are shown in Table 7, and the test results are shown in Table 8. The comparative example group was 2.5% imidacloprid cockroach bait (syringe type). The contents were white and derived from commercially available products. In the test example, 100 parts of the contents were squeezed out, 0.05 parts of 5-hydroxyfurfural diluent were added, and the mixture was mixed for 20 minutes with a mixer equipped with a spiral stirrer. The mixture was then filled into syringes and ready for use.

[0114]

[0115] Test Example 6

[0116] Product effectiveness test:

[0117] Cockroach traps containing cockroach attractants were placed in appropriate locations within the market. The number of German cockroaches caught within a certain time period was counted to test their attractiveness to wild German cockroaches in the market. The cockroach traps were placed side-by-side in each location, and the order of the traps was changed each time a location was moved. The diluent group only added diluent. The test results for Example 2 and Comparative Example 1 are shown in Table 9.

[0118] In Table 9, Comparative Example 1 is a blank cockroach house, the diluent is a cockroach house containing only the diluent, and the attractant is a cockroach house containing the cockroach attractant from Example 2.

[0119] Table 9. Number of cockroaches attracted

[0120]

[0121] As can be seen from the data in the table above, the cockroach traps used in the blank group and the diluent group were significantly less effective at attracting cockroaches than the cockroach traps in Example 1.

[0122] Test Example 7

[0123] Product effectiveness test:

[0124] Cockroach traps containing cockroach attractants were placed in appropriate locations within the market. The number of German cockroaches caught within a certain time period was counted to test their attractiveness to wild German cockroaches in the market. The cockroach traps were placed side-by-side in each location, and the order of the traps was changed each time a location was moved. Performance tests for Example 2 and Comparative Examples 2, 10, and 11 are shown in Table 11. The control group did not contain any diluent.

[0125] Table 11. Performance Tests of Example 2, Comparative Examples 2, 10, and 11

[0126]

[0127] Because cockroaches in the wild (i.e., markets and residences) exhibit variations in activity location, activity time, and life cycle, the number of cockroaches captured by the same attractant varies significantly depending on the location and time period. Therefore, the same reference object was used in each experimental group to determine the true differences in the attractability of the samples. The occurrence of individual groups showing attraction trends opposite to other groups is a random error in the experiment and does not affect the overall judgment.

[0128] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
