Honey bee Apis cerana is widely distributed in Asia and the Indonesian archipelago, including Sumatra. We studied molecular variations of A. using cytochrome c oxidase subunits 1 2 genes (cox1 cox2) cox1/cox2 intergenic spacers (igs) several altitudes six provinces explored haplotype distributions those three mtDNA markers for low-, mid-, highlands also analyzed their relationship with Sundaland markers. Our study revealed 12 new haplotypes cox1 Sumatra, while nine eight cox2 igs,...

Fusarium oxysporum has been the enemy in agriculture due to wide range of infections whole crop and postharvest. Botanical extracts traditional medicine systems were considered valuable sources for discovering new antifungals. Thus, exploration get antifungals from eco-friendly botanical as an alternative synthetic fungicides needs be expanded. Therefore, this study aims test antifungal potential seven aquadest against F. vitro. The was done on PDA media mycelial growth data collected every...

Indonesia is a biodiversity country and has much of samples bioacoustics but there are no data collected saved to be referred. Bioacoustics study frequency range, sound amplitudo intensity, fluctuation, patterns. It very useful more about population presumption species determination. This insect research done at Gunung Gede Pangrango National Park aims analyse variety cicada cricket. Methods which used recording the sounds, editing analyzing record result with Praat Raven Lite 2.0 softwares,...
