Preferences of Sitophilus zeamais to different types of Italian commercial rice and cereal pasta
Bulletin of Insectology 62 (1), 103-106
Abstract: Bioassays by means of modified Flit-Track M2 trap-device were carried out on the maize weevil Sitophilus zeamais Motschulsky (Coleoptera Curculionidae) adults. Different types of Italian rice and cereal pasta were tested. Attraction of S. zeamais to comune (variety Originario), semifino (variety Padano), fino (variety Ribe), superfino (variety Arborio), pre-cooked (fino, variety Ribe), enriched rice, parboiled (fino, variety Ribe), integrale (variety Ribe) and expanded rice were compared. Superfino and parboiled rice were more attractive than the other rice categories; on the contrary pre-cooked rice and enriched rice were less attractive to maize weevil adults. Eight different types of cereal pasta were also compared: barley, buckwheat, durum wheat, five cereals (a mixture of durum wheat, barley, spelt, oat, and rye), kamut, corn, rice and spelt. In this case the choice tests demonstrated that corn pasta was more attractive than the buckwheat pasta, durum wheat pasta and rice type; barley pasta, kamut pasta, spelt pasta, and five cereals pasta were less attractive to maize weevil adults.
