An electric pulse counter for counting and recording the number of insects killed in a commercial insect electrocutor through an on-site field server is disclosed. The pulse counter is configured of field servers, an internet, an administrative computer, and user terminals. An insect electrocutoris positioned near each of the field serversfor attracting insects present in the agricultural region and killing them by electrical discharge. An electromagnetic detection coilis disposed above or around the insect electrocutorfor detecting changes in the electromagnetic field caused by such electrical discharges. An AC signal converter circuitis disposed in each field serverand connected to the lead wire of the corresponding electromagnetic detection coilfor generating a digital count pulse from the signal outputted by the electromagnetic detection coil. The count pulse is accumulated in a storage unitin the field server and the accumulated value is transmitted to the administrative computerin response to a request therefrom. The administrative computerfunctions as a Web server to provide this data to users via the Internet.
