Occurrence, bionomics and harmfulness of Crepidodera aurea (Geoffr.) (Coleoptera, Alticidae)

A new species of the genus Crepidodera Chevrolat (Coleoptera: Chrysomelidae) from Baltic amber.

A new flea-beetle species, Crepidodera svetlanae sp. nov. (Coleoptera: Chrysomelidae: Galerucinae: Alticini) is described and illustrated from the Baltic amber. The new species is compared with the fossil and recent species of the genus. A key to species of flea beetles known from fossil resin is provided.

Isoflavones from Calpurnia Aurea subsp. aurea and their anticancer activity.

BACKGROUND Calpurnia aurea is an African medicinal plant used in many countries in Africa to treat a range of medical conditions or disorders. Extracts of the plant were shown to be active in antibacterial and antioxidant assays as well as against lice, ticks and maggots. The aim of the study was to isolate the phytochemical constituents from the plant and to test them in appropriate bioassays ...

bionomics of aphis gossypii (homoptera: aphididae) and its predators coccinella septempunctata and hippodamia variegata (coleoptera: coccinellidae) in natural conditions

bionomics of aphis gossypii glover and its predators coccinella septempunctata l. and hippodamia variegata goeze were studied in varamin (tehran province) during 11th may to 5th october 2006 on eggplant crop, with the interaction (density dependence) between the aphid and either of the predators determined. the reliable sample size (number of leaves) with a maximum variation of 6.73% was about ...

Iridoid and megastigmane glycosides from Phlomis aurea.

From the leaves of Phlomis aurea, two new iridoids of unique structures named 3-epiphlomurin (1) and phlomurin (2), a new megastigmane glucoside phlomuroside (3) and a new benzyl alcohol glycoside having the structure benzyl alcohol-O-beta-xylopyranosyl-(1-->2)-beta-glucopyranoside (4) have been isolated together with four known iridoids auroside, lamiide, 8-epiloganin and ipolamiide, two known...
