Abstract

The introduction of three killing agents (propylene glycol, DDVP and water) inside perforated probe traps was evaluated for their efficiency in trapping Coieoptera adults infesting stored cereals. The experiment was carried out in nine steel bins containing wheat, located in Central Greece, in August 1997. For the most of the 26 beetle species found, no significant differences were observed among treatments. ForSitophilus spp.,Typhaea stercorea, Aloasverns advena, Oryzae-philus surinamensis, Latheticus oryzae, Palorns ratzeburgii, P. subdepressus, andTenebroides mauritanicus, significantly less adults were found in the control traps (with no killing agent). Significant differences among three killing agents were observed only forT. stercorea andT. mauritanicus. Given that the traps supplied with killing agents were found to contain adults even in locations where control traps did not, is concluded that the addition of killing agents has increased the detection sensitivity of traps.
