Monitoring the Species of Elateridae Family in the Nursery of Gurghiu Forestry High School

Abstract

In the forestry nurseries, biological material is often heavily damaged by a rich complex of pests thatattack in the soil, or at the level of soil. The purpose of this research was the monitoring of the populationstructure of click beetles (wireworms). The monitoring of the wireworms in the larval stage was done bythe method of catching the worms with baited traps. For the bait have been used plastic cups with wheatand barley seeds in the ratio of 1:1 to which was added 15% coniferous sawdust. The larvae capturedwere identified after some aspects of external morphology. In 2011 with the help of 20 traps during themonitoring period have been captured 69 larvae of Elateridae family which is an average of 3.45 larvae/ trap. The species captured were Agriotes lineatus L., Agriotes sputator L., Agriotes obscurus L., Agriotesustulatus Schall., Selatosomus aneus L., Athous niger L., Athous haemorrhoisdalis F., Athous subfuscus Mull.,Prosternon tesselatum L. and Lacon murinum L. but Agriotes lineatus L. was the dominant specie. Thenext dominant specie was Selatosomus aneus L., which participated with 18.9% in the Elateridae faunastructure (13 specimens were caught). In 2012 in the nursery were captured 93 larvae of Elateridaefamily (with 24 larvae more than the previous year, representing an increase by 34.8 captures). In bothexperimental years in the both monitoring locations, the dominant species was Agriotes lineatus L.
