V. Zumr et al., COMPARISON OF SEASONAL RESPONSES OF HYLOBIUS-ABIETIS (L) (COL, CURCULIONIDAE) TO CHEMICAL AND NATURAL LURES IN BAITED PITFALL TRAPS, Anzeiger fur Schadlingskunde, Pflanzenschutz, Umweltschutz, 68(7), 1995, pp. 166-168
Differences in catches of Hylobius abietis (L.) adults in baited pitfa
ll traps with chemical (alpha-pinene, ethanol, water) and natural (spr
uce billets, water) lures were found not in the over-all number of tra
pped adult weevils, but in the per cent occurrence and number of old a
nd young beetles in individual periods of the season.
