The metabolic fate of C-methanol and l-C-ethanol in the adult larva of Prodenia litura has been investigated in vivo. Following the intersegmental injection of C-methanol (1.2 mg/g. insect), about 70% of the radioactivity was recovered as C02 in the expired air, after 20 hours. Also, about one fourth of the administered dose was recovered as unchanged methanol, during the first six hours. Only ...

A vast array of herbivorous arthropods live with symbiotic microorganisms. However, little is known about the nature and functional mechanism bacterial effects on plant defense responses towards herbivores. We explored role microbes present in extracts oral secretion (OS) isolated from larvae Spodoptera litura, a generalist herbivore, phytohormone signaling-dependent Arabidopsis thaliana (Arabi...

Reverse transcription quantitative polymerase chain reaction (qRT-PCR) has rapidly become the most sensitive and accurate method for the quantification of gene expression. To facilitate gene expression studies and obtain more accurate qRT-PCR data, normalization relative to stable housekeeping genes is required. These housekeeping genes need to show stable expression under the given experimenta...

Bacillus thuringiensis (Bt) being an eco-friendly bioinsecticide is effectively used in pest management strategies and, therefore, isolation and identification of new strains effective against a broad range of target pests is important. In the present study, new indigenous B. thuringiensis strains were isolated and investigated so that these could be used as an alternative and/or support the cu...

Abstrak. Hama ulat grayak (S. litura) merupakan salah satu hama yang menyebabkan daun berlubang tidak beraturan, sehingga mengganggu proses fotosintesis mengurangi produksi tanaman cabai perlu dilakukan penanganan hama. Tujuan dari penelitian untuk melihat perbandingan efektivitas B. thuringiensis dengan teknologi ozon dibangkitkan melalui reaktor Dielectric Barier Discharge Plasma dalam mengen...
