Macrophytes in oxbow lakes represent an important substrate for the Coleoptera. Two oxbow lakes the Rio Paranapanema were studied and the other two Rio Mogi-Guaçu, in the State de São Paulo, Brasil. In this study, there is greater similarity between the communities of Coleoptera of lakes greater connectivity with the main river channel or the difference in the species of Salvinia collected in t...

The occurrence of entomopathogenic fungi isolated from stored grain insect pests sampled from various geographical regions of Punjab, Pakistan, was investigated. In total, 25,720 insects from six different species were evaluated, and 195 isolates from 24 different fungal species were recovered. These included the Ascomycetes Beauveria bassiana sensu lato (Balsamo) Vuillemin (Hypocreales: Clavic...

The response of bark beetle predators and woodboring beetles to the bark beetle anti-aggregation pheromone, verbenone, was tested in the field with multiple-funnel traps baited with attractant kairomones. Catches of the predators Thanasimus undatulus (Say), Enoclerr~~ sphegeus (F.) , Erwclaus lecontei (Wolcott) (Coleoptera: Cleridae) , and hcono tu .~ complex LeConte (Coleoptera: Colydiidae) de...

the experiment was conducted to determine α-amylase activity and the effect of seven plant species extracts including punica granatum l. (punicaceae), rheum officinale b. (polygonaceae), rhus coriaria l. (anacardiaceae), artemisia sieberi b. ( compositae), peganum harmala l. (nitrariaceae) , datura stramonium l. (solanaceae) and thymus vulgaris l. (lamiaceae) on α-amylase activity of four store...

Coleoptera and Heteroptera associated with aquatic environments were studied at Berisso, near Rio de La Plata estuary (Buenos Aires Province, Argentina). Four waterbodies were characterized and compared: artificial pond, shallow pool, stream and artificial channel. Sampling was done twice a month, with a round sieve, for 12 months (April 1999 to April 2000). Sampling was quantified using a disc...

Based on a single well-preserved specimen from Eocene Baltic amber, Lilioceris groehnisp. n. is described and illustrated using phase-contrast X-ray microtomography. It is the first described species of Criocerinae (Coleoptera: Chrysomelidae) from Baltic amber. A check-list of fossil Criocerinae is provided. Placement of Crioceris pristiana (Germar, 1813) is discussed, this species is removed f...

The new species Pharaxonotha esperanzae (Coleoptera: Cucujoidea: Erotylidae: Pharaxonothinae) is described. It feeds on the pollen of the endangered Cuban cycad Microcycas calocoma (Miq.) A. DC. and breeds in its male cones. Its potential role as a pollinator of Microcycas is discussed. Resumen: Se describe la especie nueva: Pharaxonotha esperanzae (Coleoptera: Cucujoidea: Erotylidae: Pharaxono...
