Alkyl phenyl sulfide derivative and pest control agent

A pest control agent comprising:

• an alkyl phenyl sulfide derivative or an agriculturally acceptable salt thereof as an active ingredient,
• wherein the alkyl phenyl sulfide derivative is represented by the general formula [I′] or the agriculturally acceptable salt thereof
