     The insecticides, miticides, nematicides and soil pesticides of the present invention are applied in an active ingredient concentration of from 0.1 to 20,000 ppm, preferably from 1 to 2,000 ppm. The active ingredient concentration may optionally be changed depending upon the formulation, the manner, purpose, timing or place of the application and the condition of the insect pests. For instance, aquatic noxious insects can be controlled by applying the formulation having the above-mentioned concentration to the site of the outbreak, and thus, the concentration of the active ingredient in water is less than the above-mentioned range. 
     The amount of the application of the active ingredient per unit surface area is usually from about 0.1 to 5,000 g, preferably from 10 to 1,000 g, per hectare. However, in a certain special case, the amount of the application may be outside the above range. 
     Various formulations containing the compounds of the present invention or their diluted compositions may be applied by conventional methods for application which are commonly employed, such as spraying (e.g. spraying, jetting, misting, atomizing, powder or grain scattering or dispersing in water), soil application (e.g. mixing or drenching), surface application (e.g. coating, powdering or covering) or impregnation to obtain poisonous feed. Further, it is possible to feed domestic animals with a feed containing the above active ingredient and to control the outbreak or growth of pests, particularly insect pests, with their excrements. Furthermore, the active ingredient may also be applied by a so-called ultra low-volume application method. In this method, the composition may be composed of 100% of the active ingredient.

The petiole of each of eggplants with only one foliage leaf left (planted in a pot having a diameter of 8 cm and a height of 7 cm) was coated with a sticker, and about 2-3 apterous viviparous female of green peach aphid (Myzus persicae) were infested and incubated on the foliage leaf of the eggplant. After two days from the infestation, the adult insects were removed and the number of larvae was counted. Then, the foliage leaf of the eggplant infested with the larvae was dipped in the above prepared dispersion having the predetermined concentration for about 10 seconds, then dried in air and kept in a constant temperature chamber with lightening at 26° C. On the 5th day after the treatment, dead insects were counted, and the mortality was calculated by the following equation: ##EQU2## 
     The insects released from the leaf were counted as dead insects. 
     As this result, the mortality was 100% with each of Compounds Nos. 1-10, 17, 20-26, 29-40, 53-62, 64 and 65. 
     TEST EXAMPLE 4 
     Penetration and translocation test against green peach aphid (Myzus persicae) 
     Each formulation containing an active ingredient was dispersed in water to obtain a dispersion of each active ingredient having a concentration of 800 ppm. The petiole of each of eggplants with only one foliage leaf left (planted in a pot having a diameter of 8 cm and a height of 7 cm) was coated with a sticker, and about 2-3 apterous viviparous female of green peach aphid (Myzus persicae) were infested and incubated to the foliage leaf of the eggplant. After two days from the infestation, the adult insects were removed and the number of larvae was counted. Then, the eggplant infested with the larvae was treated by drenching 10 ml of the above prepared dispersion having the predetermined concentration into the soil in the pot, and was kept in a constant temperature chamber with lightening at 26° C. On the 5th day after the treatment, dead insects were counted, and the mortality was calculated in the same manner as in Test Example 3. 
     The insects released from the leaf were counted as dead insects. 
     As this result, the mortality was 100% with each of Compounds Nos. 1-10, 17, 20-26, 29-37, 53-60 and 62-65. 
     TEST EXAMPLE 5 
     Insecticidal test against common cutworm (Spodoptera litura) 
     Each formulation containing an active ingredient was dispersed in water to obtain a dispersion of each active ingredient having a concentration of 800 ppm. Leaves of cabbage were dipped in the respective dispersion for about 10 seconds, and then dried in air. A sheet of moistened filter paper was placed in a Petri dish having a diameter of 9 cm, and the dried leaves of cabbage were put on the filter paper. 10 Larvae of common cutworm (Spodoptera litura) in second or third instar were released on the leaves, and the Petri dishes were covered and kept in a constant temperature chamber with lightening at a temperature of 26° C. On the 5th day after release, dead insects were counted, and the mortality was calculated in the same manner as in Test Example 1. 
     As this result, the mortality was 100% with each of Compounds Nos. 1-10, 17, 20-40, 53-58, 60-62, 64 and 65.
