Systemic insecticides reduce feeding, survival, and fecundity of adult black vine weevils (Coleoptera: Curculionidae) on a variety of ornamental nursery crops.

Systemic insecticides for control of black vine weevil (Coleoptera: Curculionidae) in container- and field-grown nursery crops.

Black vine weevils, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae), are serious pests of container- and field-grown nursery crops. Management programs usually target the larval stage in container-grown plants and the adults in field-grown plants. We tested several new systemic insecticides for efficacy against black vine weevil in container-grown Sedum spp. and field-grown Taxus spp. In...

Prior host feeding experience influences ovipositional but not feeding preference in a polyphagous insect herbivore

Black vine weevils, Otiorhynchus sulcatus (Fabricius) (Coleoptera: Curculionidae), are globally-distributed polyphagous pests of many horticultural crops. We investigated how adult weevils were affected by host switching and, in particular, how host plant species nutritional and defensive chemistry affected subsequent host plant species selection and oviposition. Adults were fed one of three ho...

Soil-Applied Imidacloprid Translocates to Ornamental Flowers and Reduces Survival of Adult Coleomegilla maculata, Harmonia axyridis, and Hippodamia convergens Lady Beetles, and Larval Danaus plexippus and Vanessa cardui Butterflies

Integrated Pest Management (IPM) is a decision making process used to manage pests that relies on many tactics, including cultural and biological control, which are practices that conserve beneficial insects and mites, and when needed, the use of conventional insecticides. However, systemic, soil-applied neonicotinoid insecticides are translocated to pollen and nectar of flowers, often for mont...

Taxonomic use of endophallus in weevils of the genus sitona (coleoptera : curculionidae)

Comparison of Trap Types, Placement, and Colors for Monitoring Anthonomus musculus (Coleoptera: Curculionidae) Adults in Highbush Blueberries

The cranberry weevil, Anthonomus musculus Say (Coleoptera: Curculionidae), is a key (univoltine) pest of highbush blueberries in the northeast United States. To date, however, no trapping system has been developed to successfully monitor this pest. In 2012–2014, studies were conducted in commercial highbush blueberry farms in New Jersey to 1) evaluate the efficacy of various commercially availa...
