Description:
This application is a continuation-in-part of the application Ser. No. 07/956,984 filed Oct. 6, 1992, now U.S. Pat. No. 5,318,959. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to novel triazole derivative as well as insecticide and acaricide containing the same as an active ingredient. 
     2. Description of the Related Art 
     Japanese Patent laid open No. 56-154464 and DE-A-3631511 disclose that various triazole derivatives develop insecticidal and acaricidal activities. However, it can not be said that the insecticidal and acaricidal activities of these compounds described in these specifications are satisfactory. 
     Up to the present, various compounds such as organophosphorus compound, organotin compound and the like have been used for the control of pests in farm and garden crops and mites. However, these compounds have been used over many years, so that the above injurious insects have a resistance to chemicals to a certain extent and it recently becomes difficult to control these insects. Particularly, this tendency is conspicuous in lepidopteran injurious insects, mites and aphids and becomes serious. As a result, it is demanded to develop new types of insecticide and acaricide having a different function. 
     SUMMARY OF THE INVENTION 
     The inventors have made various studies in order to create novel insecticides and acaricides having a very high effect against wide injurious pests and capable of safely using, which have never been found in the conventional technique, in the development of the insecticide and acaricide having a function different from that of the conventional one. 
     Further, the inventors have synthesized various triazole derivatives and examined their physiological activities. As a result, the inventors have found that novel triazole derivatives having a general formula [I] as mentioned later have an excellent effect against wide injurious pests in farm and garden crops, particularly lepidopteran injurious insects, mites and aphids and also develop a very high effect against eggs and larvae of mites and larvae of aphids having a resistance to the conventional chemicals, and the invention has been accomplished. 
     According to the invention, there is the provision of a triazole derivative having the following general formula [I]: ##STR2## (wherein R 1  is an alkyl group, X is a hydrogen atom, a halogen atom, an aklyl group, an alkoxy group, an alkylthio group, a nitro group, a cyano group or trifluoromethyl group, n is an integer of 1-5 provided that when n is 2 or more, X may be an optional combination of same or different atoms or groups, A is an oxygen atom, a sulfur atom, a lower alkylene group, a lower alkyleneoxy group, an oxy-lower alkylene group or a lower alkyleneoxyalkylene group, k is 0 or 1, R 2  is a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, trifluoromethyl group or trifluoromethoxy group, and m is an integer of 1-5 provided that when m is 2 or more, R 2  may be an optional combination of same or different atoms or groups). 
     Furthermore, the invention provides an insecticide or an acaricide containing the above triazole derivative as an active ingredient. 
     Throughout the specification, the term &#34;lower&#34; means that the carbon number in the group added with this term is not more than 6. 
     Further, the term &#34;alkyl group&#34; means a straight or branched-chain alkyl group having a carbon number of 1-30, which includes, for example, methyl group, ethyl group, n-propyl group, isopropyl group, n-butyl group, isobutyl group, sec-butyl group, t-butyl group, n-pentyl group, isoamyl group, neopentyl group, n-hexyl group, isohexyl group, 3,3-dimethylbutyl group, n-heptyl group, 5-methylhexyl group, 4-methylhexyl group, 3-methylhexyl group, 4,4-dimethylpentyl group, n-octyl group, 6-methylheptyl group, n-nonyl group, 7-methyloctyl group, n-decyl group, 8-methylnonyl group, n-undecyl group, 9-methyldecyl group, n-dodecyl group, 10-methylundecyl group, n-tridecyl group, 11-methyldodecyl group, n-tetradecyl group, 12-methyltridecyl group, n-pentadecyl group, 13-methyl-tetradecyl group, n-hexadecyl group, n-heptadecyl group, n-octadecyl group, n-nonadecyl group, n-eicosyl group and the like. 
     The terms &#34;alkoxy group&#34; and &#34;alkylthio group&#34; are (alkyl)-O-- group and (alkyl)-S-- group in which the alkyl portion has the same meaning as mentioned above, respectively. 
     The term &#34;halogen atom&#34; means fluorine, chlorine, bromine and iodine. 
     The term &#34;lower alkylene group&#34; means a straight or branched-chain alkylene group having a carbon number of 1-4, which includes, for example, --CH 2  --, --CH 2  CH 2  --, --CH(CH 3 )--, --CH 2  CH 2  CH 2  --, --CH(CH 3 )CH 2  --, --C(CH 3 ) 2  --, --CH 2  CH 2  CH 2  CH 2  --, --CH(CH 3 )CH 2  CH 2  --, --CH 2  CH(CH 3 )CH 2  -- and the like. 
     The term &#34;lower alkyleneoxy group&#34; means -(lower alkylene)-O-- group in which the lower alkylene portion has the same meaning as mentioned above. 
     The term &#34;oxy-lower alkylene group&#34; means --O-(lower alkylene)- group in which the lower alkylene portion has the same meaning as mentioned above.
