The reaction temperature is usually in the range of -78° C. to 200° C. 
     After completion of the reaction, ordinary post-treatments such as organic solvent extraction and concentration are conducted to isolate the desired compound of the present invention; if necessary, purification may be conducted by a technique such as chromatography or recrystallization. 
     The compound (VI) which is used as the starting material in the production process (A) can be produced, for example, by the following production process (a). 
     Production Process (a) 
     The process comprises reacting a compound of the general formula (IX): ##STR6## wherein X and R 2  are each as defined above, with a compound of the general formula (X): ##STR7## wherein R 1  is as defined above and W is chlorine, bromine or --OCOR 1  .

Examples of the base which can be used are organic bases such as triethylamine, pyridine, 4-N,N-dimethylaminopyridine and N,N-diethylaniline; inorganic bases such as sodium hydroxide, sodium hydride and potassium carbonate; organic metal bases such as n-butyl lithium and lithium diisopropylamide. 
     In this process, it is not necessary to use a solvent; it is, however, generally preferred that the reaction is effected in an inert solvent. When a solvent is used, it depends upon the substituent W in the general formula (X) or the kind of base used. Typical examples of the solvent ,are aromatic hydrocarbons such as benzene, toluene and xylene; pyridine compounds such as pyridine and picoline; halogenated hydrocarbons such as chloroform, carbon tetrachloride, 1,2-dichloroethane, 1,1,1-trichloroethane, tetrachloroethylene, trichloroethylene, chlorobenzene: and o-dichlorobenzene; aliphatic hydrocarbons such as n-hexane and n-heptane; alicyclic hydrocarbons such as cyclohexane; alcohols such as methanol, ethanol and isopropanol; aprotic polar solvents such as N,N-dimethylfonnamide and dimethylsulfoxide; ethers such as tetrahydrofuran and diethyl-ether; ketones such as acetone and methyl isobutyl ketone; water; or mixtures thereof. 
     The amounts of reaction reagents to be used in the production process (a) are usually in the range of 1 to 100 moles per mole of the compound of the general formula (IX) for each of the base and the compound of the general formula (X). The reaction temperature is usually in the range of -20° C. to 200° C. 
     After completion of the reaction, ordinary post-treatments such as extraction with an organic solvent and concentration are conducted to isolate the compound of the general formula (VI). 
     The compound of the general formula (IX) which is used as the starting material in the production process (a) is a known compound, which can be produced, for example, by a process as described in the U.S. Pat. No. 4,344,893.

     The following test examples will illustrate that the hydrazone compounds of the present invention are useful as an active ingredient of insecticides. In these test examples, the hydrazone compounds of the present invention are designated by the corresponding numbers as shown in Tables 4 and 5, and the compounds used for comparison are designated by the corresponding symbols as defined below. 
     Compound A: 4-chloro-4&#39;-(trifiuoromethylsulfonyloxy)benzophenone-N&#39;-acetylhydrazone (which is included in the compounds of the general formula described in the U.S. Pat. No. 4,344,893) 
     Compound B: 4-chloro-4&#39;-(trifluoromethylsulphonyloxy)benzophenone-N&#39;-(ethoxycarbonyl)hydrazone (which is identical to compound 83 as described in column 20 of the U.S. Pat. No. 4,344,893) 
     TEST EXAMPLE 1 
     Insecticidal Test on Spodoptera Litura 
     Each of the test compounds was formulated into an emulsifiable concentrate according to Formulation Example 1, which was then diluted with water to a concentration of 500 ppm. With 2 ml of the dilution was impregnated 13 g of an artificial diet for Spodoptera litura prepared in a polyethylene cup having a diameter of 11 cm. Then, ten fourth-instar larvae of Spodoptera litura were set free in the cup. After six days, the survival of larvae was examined to determine the mortality. 
     As a result, it was found that the compounds 1 to 32 exhibited the mortality of at least 80%. By contrast, the mortality in the non-treated field was 0%. 
     TEST EXAMPLE 2 
     Ovicidal and Larvicidal Tests on Plutella Xylostella 
     Each of the test compounds was formulated into an emulsifiable concentrate according to Formulation Example 1, which was then diluted with water to a concentration of 50 ppm. In the dilution were dipped four sprouted Japanese radishes which have been harvested five to six days after the seeding (i.e., two Japanese radishes on which 100 to 150 eggs of Plutella xyiostella were laid and two Japanese radishes on which no egg was laid), followed by air drying, and they were put in a polyethylene cup having a diameter of 5.5 cm. After six days, the hatching and the survival of larvae were examined to determine the ovicidal and larvicidal rates. 
     As a result, it was found that the compounds 1-8, 10-15, 18-25 and 30-32 exhibit the ovicidal and larvicidal rate of at least 90%. By contrast, the ovicidal and larvicidal rate in the non-treated field was less than 90%. 
     TEST EXAMPLE 3 
     Insecticidal Test on Larvae of Diabrotica Undecirnpunctata 
     Each of the test compounds was formulated into an emulsifiable concentrate according to Formulation Example 1, which was then diluted with water to a concentration of 50 ppm. On the bottom of a polyethylene cup having a diameter of 5.5 cm was laid a filter paper having the same diameter. Then, 1 ml of the dilution was dropped on the filter paper. Then, about 30 eggs of Diabrotica undecimpunctata were put on the filter paper, and a sprouted corn as a diet was put in the cup. After eight days, the survival of hatched larvae was examined. 
     As a result, it was found that the compounds 1-7, 9-12, 14-22, 24-25 and 30-32 exhibited the mortality of at least 90%. By the contrast, the mortality in the non-treated field was less than 90%. 
     TEST EXAMPLE 4 
     Insecticidal Test on Larvae of Blattella Germanica 
     Each of the test compounds was formulated into an emulsifiable concentrate according to Formulation Example 1, which was then diluted with water to a concentration of 500 ppm. On the bottom of a polyethylene cup having a diameter of 5.5 cm was laid a filter paper having the same diameter. Then, 0.7 ml of the dilution was dropped on the filter paper, and about 30 mg of sugar as a bait was uniformly put on the filter paper. Ten male adults of Blattella germanica were set free in the cup, and a lid was put on the cup. After six days, the survival of male adults was examined to determine the mortality. 
     As a result, it was found that the compounds 1-3, 5, 7-9, 12-14, 20-23, 25-28 and 30 exhibited the mortality of 100%. 
     TEST EXAMPLE 5 
     Insecticidal Test on Culex Pipiens Pallens 
     Each of the test compounds was formulated into an emulsifiable concentrate according to Formulation Example 1, which was then diluted with water (active ingredient concentration, 3.5 ppm). To 100 ml of deionized water was added 0.7 ml of the dilution, in which twenty final instar larvae of Culex pipiens pallens were set free. After one day, the survival of the larvae was examined to determine the mortality. 
     As a result, it was found that the compounds 1-32 exhibited the mortality of at least 90%. 
     TEST EXAMPLE 6 
     Acute Toxicity by Oral Application to Mice 
     Each of the test compounds, i.e., compound 1, 4, 12, 24 and 28 of the present invention and compounds A and B for comparison, was diluted to a predetermined concentration with corn oil. After about twenty-hour fasting, 0.1 ml of the dilution per 10 g weight for each ICR male 6-week old mouse (weight, 24 to 31 g) was forcibly applied to the stomach of each animal. The mice was given food and water since four hours after the application, and kept in a cage. Seven days after the application, the survival of the mice was examined to determine the mortality (4 mice per group). The results are shown in Table 6.
