Epitrix hirtipennis (Melsheimer, 1847) (Coleoptera: Chrysomelidae: Galerucinae: Alticini), a leaf beetle native to North America, is recorded for the first time from Hungary. Several specimens were found on tobacco (Nicotiana tabacum L.) plantations in eastern and central parts of country. Its life cycle importance as pest are briefly discussed.
Environ. En!om,,!. 12: 1892-1897 (1983) ABSTRACT We determined the susceptibility of the Colorado potato beetle, Leptinotarsa decem/ineata (Say) to the fungal pathogen Beauveria bassiana (Balsamo)when reared on So/anum tuberosum L., So/anum dulcamara L., So/anum carolineme L., and Lycopersicwn escu/entum Miller growing in both the field and greenhouse. With the exceptionof L. escu/entwn, the ho...

Psyllototus doeberli sp. nov., a second species of the paleoendemic genus is described. This is the first named species of Alticini from the Upper Eocene Baltic amber of Yantarny, Kaliningrad region, Russia. A checklist of known Alticini from fossil resins is provided.
Resistance management is essential for maintaining the efficacy and long-term durability of transgenic corn engineered to control western corn rootworm (Diabrotica virgifera virgifera Le Conte). Theoretically, a refuge can be provided by growing susceptible (refuge) plants in either a separate section of the field adjacent to resistant (transgenic) plants, or as a seed mixture. We examined the ...
A new genus (Penghou) with a single new species (P. yulongshan) from Yunnan Province in China is described and illustrated. It is compared to Hespera Weise, Hesperomorpha Ogloblin, Laotzeus Chen, Luperomorpha Weise, Mandarella Duvivier, Omeiana Chen, Stenoluperus Ogloblin and Taiwanohespera Kimoto.
Under the framework of the DAISIE consortium, whose main mission is to make an inventory of the alien invasive species of Europe and its islands, we review the current state of knowledge and provide an up-to-date catalogue and distributional status for alien seed beetles (Coleoptera: Chrysomelidae: Bruchinae) in Europe. This work is based on studies of the species detected from the last century...
BACKGROUND Neonicotinoid insecticides were first used commercially for Colorado potato beetle [Leptinotarsa decemlineata (Say), Coleoptera: Chrysomelidae] control in the United States in 1995, and since then have been critical for management of this pest. Field populations from the northeastern and midwestern United States were tested from 1998 to 2010 for susceptibility to imidacloprid and thi...
The Gallerucida singularis species group is established. Gallerucida gebieni Weise, status restored and G. haroldi Weise, status restored are resurrected from synonymy with G. singularis Harold. Lectotypes are designated for G. haroldiand G .tonkinensis Laboissi6èe. The species are differentiated mainly based on the structure of the endophallic sclerites.
