Benefit-cost analysis of apiculture farm.
The market of bee products is being expanding in the last years. To make the apicultural farms successful, it requires raw materials, manpower, market but also quality of bee products (K. H. Devkota, 2006). In this context, the aim of the present study is to evaluate the profitability of apicultural farms by implementing the modern management instruments: new technologies, good apicultural practices, and HACCP guide. Benefit-cost analysis was applied to evaluate the apicultural farms of Transylvania. The analyse was made in two situations: 1 st -implementation of the classic methods and 2 nd – implementation of the modern management system (diversification of the products and increase of the quantity). The costs of production were divided in two categories: direct costs and fixed costs.
Benefit-Cost Analysis of Apiculture Enterprise: A Case Study of Jutpani VDC, Chitwan, Nepal
A survey study was conducted to study the benefit-cost analysis of apiculture enterprise in Jutpani VDC, Chitwan district. Data were collected by interviewing randomly selected 18 beekeepers for sample survey. Benefit : Cost (BC) ratio of apiculture was computed by including and excluding the revenue obtained from colony selling. Only 61.11% of beekeepers sold bee colonies for earning income. The study revealed that BC ratios of apiculture were 2.41 and 1.58 in the case of inclusion and exclusion of the income received from the colony selling, respectively. It showed that apiculture industry was running in profit in both cases. In the former case, the BC ratio ranged from 0.97 to 6.22 and about 88.88% beekeepers were in profit. The BC ratio in the later case ranged from 0.43 to 3.41 and about 77.77% beekeepers were in profit. The number of colonies ranged from 2 to 54 with an average of 21.33 colonies per bee farm. In the former case, average annual income was Rs. 70758.33 (US$ 969.29 approximately) per farm and Rs. 49588.31 (US$ 679.29 approximately) in the later case. Likewise, the average income per colony per annum was Rs. 3317.31 (US$ 45.44) and Rs. 1777.65 (US$ 24.35 approximately) in the former and later case, respectively. Key words : Apiculture, benefit-cost ratio, beekeeper

Melanocins A, B and C, new melanin synthesis inhibitors produced by Eupenicillium shearii. I. Taxonomy, fermentation, isolation and biological properties.
New melanin synthesis inhibitors, melanocins A, B and C, were isolated from the fermentation broth and mycelium extract of Eupenicillium shearii F80695. Melanocin A, an isocyanide compound, inhibited mushroom tyrosinase and melanin biosynthesis of B16 melanoma cells with IC50 value of 9.0 nM and MIC value of 0.9 microM, respectively. Melanocin A also inhibited growth of Streptomyces bikiniensis. While, the structurally very related but non-isocyanide compounds melanocins B and C did not show inhibitory activity in these assays. Melanocins A, B and C showed potent antioxidant activity with scavenging activity of DPPH radical and superoxide anion radical.
