The exotic beetle Ophraella communa LeSage (Coleoptera: Chrysomelidae) was first found in 1996 in Japan and has rapidly expanded its distribution. This study investigated variation in flight activity and its genetic basis in this beetle by measuring its flight time on a flight mill system. The O. communa population exhibited substantial variation in flight activity among individuals. More than ...

Impacts of semiochemical-based insecticidal bait applications on beneficial arthropod groups common to field corn, Zea mays L., habitats were assessed in areawide-managed field sites in South Dakota and Iowa during 1997 and 1998. Slam, a commercial bait formulation comprised of 87% cucurbitacin and 13% carbaryl insecticide, was used for management of adult rootworm, Diabrotica spp., and control...

Australotymnes jipijapa new genus, new species (type locality: Ecuador) is described. Adults were collected from vegetation during the rainy season in disturbed and converted dry forest in western Ecuador.

The western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is a major pest of corn, Zea mays L., in North America that has recently invaded Europe. A loss of ovipositional fidelity to cornfields has allowed the species to circumvent crop rotation as a means of control in part of its range in the United States. Analyses of variation at eight microsatellite loc...

A new species of chrysomeline leaf beetle, Paropsisterna selmani Reid & de Little, is described, including all larval in-stars. This species, native to Australia, is now a significant pest of Eucalyptus plantations in Australia and Ireland, and has been recorded in southern England. Its occurrence in the British Isles represents the first record of establishment of a eucalypt feeding chrysomeli...

Abstract First North American records are presented for Cryptocephalus moraei (Linnaeus, 1758) (Coleoptera: Cryptocephalinae) and Psylliodes dulcamarae (Koch, 1803) Galerucinae: Alticini), as confirmed by morphology DNA barcoding. Additional information is about phenology host use C. , the first European Cryptocephalinae to be found elsewhere conclusively adventive. expected have no ecological ...

Heterochromatin characteristics have been studied in Leptinotarsa decemlineata belonging to the leaf beetles (Chrysomelidae) and compared to the thoroughly analysed heterochromatin of the mealworm beetle Tenebrio molitor, representing darkling beetles (Tenebrionidae). C-banding reveals heterochromatin in pericentromeric regions of all chromosomes of both species; however heterochromatic blocks ...

A male-produced aggregation pheromone was identified for the Colorado potato beetle Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae). While male beetles produced only minor amounts of the pheromone, its production could be enhanced by topical application of juvenile hormone III (JH III) (eightfold), by antennectomy (40-fold) or by the combined treatment of JH III and antennectomy (al...

Although some species of Cryptocephalinae (Coleoptera: Chrysomelidae) have been documented with ants (Hymenoptera: Formicidae) for almost 200 years, information on this association is fragmentary. This contribution synthesizes extant literature and analysizes the data for biological patterns. Myrmecophily is more common in the tribe Clytrini than in Cryptocephalini, but not documented for Fulci...

Since more than half a century, Pierre Hippolyte Auguste Jolivet has been the inspiring head of the community of leaf beetle researchers (Fig. 1). He promoted research on Chrysomelidae not only by his nearly 500 publications (see list below), but even more so by his personal input to the international and European symposia on leaf beetles, and especially by the six volumes he co-edited (nos. 27...
