Abstract The alfalfa weevil ( Hypera postica Gyllenhal, Coleoptera: Curculionidae) is a major pest of crops. Chemical control measures are inefficient, but the larvae often infested by parasitoid wasps genus Bathyplectes Förster (Hymenoptera: Ichneumonidae), which offer potential biological strategy. development effective requires identification species, conventional methods involve rearing par...

The alfalfa weevil Hypera postica (Gyllenhal) (Coleoptera: Curculionidae) is a major pest of worldwide. In Spain, insecticide sprayings are mainly used for control with low efficacy. As potential more sustainable method, we determined the effectiveness an winter cutting reducing populations in spring and its interaction parasitism rate due to Bathyplectes spp. (Hymenoptera: Ichneumonidae).

The guild of stem-infesting insect pests of sunflower, Helianthus annuus L., within the central Plains is a concern to producers chiefly due to losses caused by plant lodging from the sunflower stem weevil, Cylindrocopturus adspersus (LeConte) (Coleoptera: Curculionidae), and Dectes texanus texanus LeConte (Coleoptera: Cerambycidae).
