The tested isoamyl alcohol-based semisynthetic bisexual lure containing red wine as an organic component attracted flies of 10 families, including economically importa...

The white-line dart, Euxoa tritici L. (Lepidoptera: Noctuidae), is a polyphagous pest of many field crops in Europe. The cutworms feed on various crops (e.g., alfalfa, lettuce, potato , beet, and other row crops (see: https://www.gov. mb.ca/agric ultur e/crops/ insec ts/cutwo rms-field-crops. html) and also attack a wide range of low-growing plants...

The diurnal bees, lepidopterans, and other pollinators are among the most studied flower-visiting insect taxa. They mostly play distinct functions in temperate grasslands and ecotones of grassland-forest mosaics (such as in forest steppes). Although orthopterans are widely distributed in these habitats, however, their flower visitation is nearly un...
