RESUMO
Tetralonioidella Strand 1914 is a very rare apid genus globally, of which only two species, Tetralonioidella himalayana (Bingham, 1897) and Tetralonioidella tricolor (Lieftinck, 1972), are known from India. They are known to be cleptoparasitic on species of Habropoda Smith, 1854 and Elaphropoda Lieftinck, 1966. During hymenopteran survey in Arunachal Pradesh, we encountered Tetralonioidella himalayana (Bingham, 1897) and observed their behavioral regime, which is very poorly known. The identifying characteristics of both male and female, their foraging behavior, floral preference, distribution pattern, and possible host association have been studied. Exclusive floral association and host specialization are potential contributing factors to the rarity of T. himalayana. Such factors may limit the distribution range of the species. A priori sampling resolution with genetic and demographic exploration is required to evaluate the present status of such bee species.
RESUMO
The primary aim of this present study was to utilize the residual biomass (DB) of Spirulina platensis algae, left after in-situ transesterification, for biochar preparation. This is a solid waste residue of biodiesel industry. The biochar (BC) prepared was examined for its capacity to adsorb congo red dye from the aqueous solution. The results were compared with other adsorbents used in the study such as commercial activated carbon (AC), original algae biomass (AB) and DB. The results of proximate analysis of BC showed the decrease in the percentage of volatile matter and an increase in fixed carbon content compared to DB. The physico-chemical properties of BC were studied using elemental analysis, SEM, FTIR and XRD techniques. The AC and BC adsorbents showed better performance in removing 85.4% and 82.6% of dye respectively from solution compared to AB (76.6%) and DB (78.1%). The effect of initial dye concentration, adsorbent dosage and pH of solution on the adsorption phenomena was studied by conducting the batch adsorption experiments. The highest specific uptake for biochar was observed at acidic pH of 2 with 0.2 g/100 ml of adsorbent dosage and 90 mg/l of initial concentration. The equilibrium adsorption data were fitted to three isotherms, namely Langmuir, Freundlich and Temkin. Freundlich model proved to show the best suited results with value of correlation coefficient of 99.12%. Thus, the application of DB for production of biochar as potential adsorbent supports sustainability of algae biodiesel.
