Folic acid is a fast degradable vitamin, hence showing reducing functionality. Therefore, engineering of an efficacious vehicle for oral delivery of folic acid via encapsulation using an appropriate matrix is important. As eligible matrices, alginate and chickpea protein were compared in terms of stability, release kinetics, transport mechanism and bioaccessibility. Both matrices yielded particles of submicron-range with high encapsulation efficiency. Stability, in vitro release and bioaccessibility studies displayed reduced degradation, protection against gastric pH and increased bioaccessibility (80%) by alginate particles. The protein matrix also displayed slower release and higher bioaccessibility of folic acid compared to the free compound. Release of folic acid from alginate particles showed Fickian diffusion, while release from chickpea protein particles showed quasi Fickian diffusion and super case II transport mechanism at gastric and intestinal pHs, respectively. In conclusion, alginate particles were superior in affording thermal and photo stability, pH dependent release and higher bioaccessibility.

Chilli thrips (<em>Scirtothrips dorsalis</em> Hood) is the most important pest and cause leaf curl complex in chilli. Farmers misuse pesticides for control; leading to resistant development, high residue levels, and environmental pollution. Laboratory experiments using <em>Amblyseius swirskii</em> and <em>Orius leavigatus</em> Fieber in combination reduced the thrips population significantly after two weeks. Reduction of biological agents population was statistically significant after 04 weeks and 03 weeks in <em>Amblyseius swirskii</em> and <em>Orius leavigatus</em> respectively. Thus, combined use of <em>Amblyseius swirskii</em> and <em>Orius leavigatus</em> effectively controlled thrips, but the biological agents did not multiply though bee’s honey was provided as alternate food source.

Abstract not available

Mangroves represent one among the most carbon retaining ecosystems in the world, due to their high productivity and huge carbon sinking capacity within biomass and substratum. Majority of Sri Lankan mangroves are located on the north-eastern coast. Since they were highly isolated during the last three decades, there are limited research publications related to those. Present study was conducted at six major mangrove ecosystems in the northeast coast of Sri Lanka with the objectives of reporting the present vegetation structure and to estimate their capacity of the carbon pool with plant biomass. Highest mangrove diversity was recorded at Yanoya followed by Thondamannaru and Uppar lagoons. A critically endangered mangrove species, <em>Ceriops decandra</em>, was recorded at Yanoya mangrove ecosystem, this may be the first-time scientific record of the species in the recent history. Relatively higher biomass values (159 - 460 Mg ha^-1), recorded at Yanoya estuary. The average value for above ground biomass of the northeast coast of Sri Lanka was 226.34 Mg ha^-1. Statistically significant linear relationships occurred between the biomass and the mangrove vegetation structure, as well as between the soil salinity and the carbon retention capacity of mangrove. Results of the present study assist to add new knowledge and rationalize the conservation and proper management of mangrove ecosystems on the northeast coast of Sri Lanka.
