Article: Survival of male click beetles, Agriotes obscurus L., (Coleoptera: Elateridae) during and after storage at different temperatures

The dusky wireworm, Agrietes obscurus L. (Coleoptera: Elateridae) is a significant pest of vegetable and field crops in the Fraser Valley of BC (Vernon et al. 2001). Adults emerge from the soil from late March through May and die soon after mating (males) or egg laying (Brian 1947), restricting their availability for research and necessitating storage methods that prolong survival. Here we compare beetle survival during and after storage at various temperatures for various durations.

Male A. obscurus beetles were collected at the Pacific Agri-Food Research Centre (Agassiz, BC) during their peak emergence (1st wk of May, 2005) and placed in groups of 10 beetles into 150 ml plastic containers ...
