ساقه­ خواران نیشکر در ایران شامل دو گونه Sesamia cretica Led. و S. nonagrioides Lef. می­ باشند که از مهم ترین آفات نیشکر محسوب می­ شوند. مهم­ ترین دشمن طبیعی ساقه­ خواران نیشکر در خوزستان زنبور پارازیتوئید Telenomus busseolae Gahan است که نقش مهمی در تنظیم جمعیت میزبان ایفا می­ نماید. به منظور ارزیابی تأثیر میزبان بر زنبور T. busseolae یک بررسی آزمایشگاهی انجام شد. برای این منظور، طول دوره بلوغ...

From aerial parts of the fern Pteris multifida Poir. (Polypodiaceae) two diterpenes, entkaurane-2 beta, 16 alpha-diol and ent-kaur-16-ene-2 beta, 15 alpha-diol, were isolated by repeated column chromatography using silica gel and silica gel impregnated with silver nitrate. The structures were confirmed by spectroscopic methods. Both compounds showed a moderate cytotoxicity to Ehrlich ascites tu...

Six new ent-15-oxokauran-19-oic acid derivatives, named pterisolic acids A-F (1-6), were isolated from the ethanol extract of the fern Pteris semipinnata (Pteridaceae), and the structures of these new ent-kauranoids were elucidated on the basis of extensive spectroscopic studies and single crystal X-ray diffraction analysis.

Self-incompatibility (SI) in plants is a classic example of a trait evolving under strong frequency-dependent selection. As a consequence, population genetic theory predicts that the S locus, which controls SI, should maintain numerous alleles, display a high level of nucleotide diversity, and, in structured populations, show a lower level of among-population differentiation compared to neutral...

Brake fern, Pteris vittata, not only tolerates arsenic but also hyperaccumulates it in the frond. The hypothesis that arsenic hyperaccumulation in this fern could function as a defense against insect herbivory was tested. Fronds from control and arsenic-treated ferns were presented to nymphs of the grasshopper Schistocerca americana. Feeding damage was recorded by visual observation and quantif...

Pteris vittata L., a fern was evaluated for its alpha amylase inhibitory potential owing to its previously reported antihyperglycemic activity. This Pteridophyte was also assayed for its free radical inhibition ability in ABTS decolourisation assay followed by quantification and HPTLC of polyphenols. The Porcine pancreatic alpha amylase inhibition was studied invitro and compared with standard ...
