Isolation and structure determination of nematicidal iridoid sweroside from Alstonia scholaris

  The methanol extract of aerial parts of Alstonia scholaris (sapthaparna) was found to possess good nematicidal activity against the plant parasitic nematode, Meloidogyne incognita. The active nematicidal compound was isolated from the methanol extract by column chromatographic techniques and purified by TLC. Chemical structure was determined by chemical and spectroscopic methods to be that...

A new species of genus Squamigera (Insecta: Zygentoma: Nicoletiidae) from the Mayan ruins of Palenque, Chiapas, Mexico

  Due to the difficulty in collecting specimens, the genus Squamigera (Insecta: Nicoletiidae: Cubacubaninae) remains one of the least studied groups of the American nicoletiid insects. before this investigation, only six specimens were available for study. Furthermore, previous assessments of its phylogenetic relationship within the Cubacubaninae used incomplete 16S rRNA sequences that had...
