Related Background Art

Although numerous pest control agents have been discovered so far, the development of novel drugs which has high safety is still required in view of the problem of reduction in drug sensitivity, the issue of long-term efficacy, safety to workers or safety in terms of environmental impacts. Further, in agriculture, in order to achieve a reduction in labor for the pest control work, it is general to mix a plurality of components of a chemical for pest control and treat seeds or farm products during the growing seedling period with the chemical, and under these circumstances, it is required to use a long-term residual efficacy type chemical having penetrating and migrating property. In addition, it is also possible to solve problems such as scattering of a chemical to the surrounding environment outside agricultural land or exposure to a person who performs pest control by seed treatment or treatment during the growing seedling period.

Reference Test Example 19 Pest Control Test of Nilaparvata Lugens

A rice seedling in pot culture was subjected to soil drench with a solution of the compound of Formula (I), which had been prepared so as to be a 10% acetone water. Three days after the treatment, ten second instar larvae of Nilaparvata lugens, which had been collected outdoors and proliferated indoors, were each released to the rice seedling.

Furthermore, for comparison, the test against a species of Nilaparvata lugens which is highly susceptible to imidacloprid was performed by the same method as described above, and the results thereof are shown in Table 45. As described in Table 45, Compound P212 and Compound 1-20 exhibited high insecticidal effects against susceptible species and drug resistant species of Nilaparvata lugens, and the death rates of larvae at 0.005 mg/seedling were (susceptible species) 100% and 100%, (resistant population I) 95% and 77% and (resistant population II) 100% and 85%, respectively. Meanwhile, the death rates of imidacloprid at 0.05 mg/seedling were (susceptible species) 100%, (resistant population I) 38% and (resistant population II) 69%, and the insecticidal effect thereof was also low even at a high dose. From the above results, it became obvious that Compound P212 and Compound 1-20 have high insecticidal effects even against Nilaparvata lugens resistance against imidacloprid.

Test Example 15 Test of the Control of Haemaphysalis Longicornis

A capsule with a diameter of 2 cm and a height of 2 cm was attached to the dorsal surface of a mouse. A compound of Formula (I), ivermectin, moxidectin, permethrin, amitraz, fipronil, spinetram and the mixture of the compound of Formula (I) and each insecticide were dissolved in ethanol at the concentrations given in Table O, and each of these was dripped onto the surface of a mouse body within a capsule. After thorough drying, eight Haemaphysalis longicornis nymphs were released and the top of the capsule was sealed with a lid. The mouse was kept in a cage at 25° C. using a 12-hour light period and a 12-hour dark period. Five days after the release, the capsule was removed and the number of surviving and dead nymphs and the number of engorged individuals were counted and the insect mortality and agonal rate was calculated by the following equation.

Insect mortality and agonal rate (%)={number of dead and agonal insects/(number of survived insects+number of dead and agonal insects)}×100

The results showed that, at a rate of 0.009 μg of ivermectin or moxidectin, the mixed agent of either with Compound P212 also gave a tick control effect that was the same as treatment with ivermectin, moxidectin, permethrin, amitraz, fipronil and spinetram alone and mixed treatment with ivermectin, moxidectin, permethrin, amitraz, fipronil and spinetram is thus possible.
