Butterfly-plant interaction in a forest ecosystem is a dynamic key factor that determines the status of a forest. A research team of the Environmental Biology and Biodiversity Laboratory (EBBL) of the department of Zoology, Dhaka University worked successfully on a population census of butterflies in some forests by using their newly innovated method the “Biotic-epicntre technical model”. This method deals with two important points for practicing it in the field condition. These are ethological aspects of the butterflies and application of epicentre-spot-design. In total 202 butterfly species (belonging to seven different families) were studied in the forests experimental stations of Bangladesh. The families are Hesperiidae, Papilionidae, Nymphalidae, Pieridae, Danaidae, Lycaenidae and Satyridae. The „vulnerability status‟ comprises„Available (Av)‟, „Rare (Rr)‟, „Near Threatened (Nt)‟, „Threatened (Tr)‟, „Critically Threatened (Ct)‟ and „Endangered (En)‟. The study revealed that the highest number of host-plant families (25 families) was used by lycaenids (45 species). The family Satyridae had the lowest number hostplant families (only 2). The second highest number of host-plant families (24 families) was associated with the family Nymphalidae (34 butterfly species). 38 butterfly species of Hesperiidae were associated with only nine families of the host-plants. The family Papilionidae (19 species) was related to only five host plant families. The butterflies (23 species) of the family Pieridae were found to depend on ten host-plant families. The members of the family Danaidae (12 species) were found on four host-plant families. More than 35 forest-areas of Bangladesh were included in the present investigation. Out of the total studied species (202), six species were found and declared „Endangered‟. Among the examined butterflies, 12, 13, 9, 64 and 98 species hold the status of Critically Threatened, Threatened, Near Threatened, Rare and Available respectively. The population census of the butterflies was carried out in three major forest areas of Bangladesh. The biodiversity assessment methods practiced in the various experimental fields have been illustrated with their respective different figures.</p> <p>J. Biodivers. Conserv. Bioresour.

The experiment was conducted in a randomized complete block design (RCBD) replicated thrice with six treatments. Growth parameters, <em>viz. </em>plant height, base diameter, green weight, dry matter weight, fiber yield and stick yield were assessed. The highest height (3.7 m), maximum base diameter (16.17 mm), maximum green plants yield with leaves (58.65 t ha<sup>-1</sup>), maximum green plants yield without leaves (37.46 t ha<sup>-1</sup>), highest fiber yield (2.87 t ha<sup>-1</sup> ) and highest stick yield (6.2 t ha<sup>-1</sup>) were recorded with T<sub>2</sub>(100% RDF + 0% effluent). From the economic analysis point of view, it was found that T<sub>4</sub> (50% RDF + 50% effluent) showed higher BCR (2.73) than T<sub>2</sub> (100% RDF + 0% effluent). Although the best growth performance was observed in T<sub>2</sub> (100% RDF + 0% effluent), but in terms of BCR T<sub>4</sub> (50% RDF + 50% effluent) was the best.</p> <p>J. Biodivers. Conserv.

The results showed that <em>Aedes caspius </em>was most abundant in all the three sites surveyed, with a rate of 66.43% of the total fauna indicated. While the remaining two mosquito species have different rates during the study period. From the estimates of the main physicochemical parameters of the water, we were able to show the relationship between the abundance of these mosquito species and the typology of breeding sites. These mosquitos were present in alkaline sites, with medium mineralization and high oxygen levels. Thus, these species likely choose salty water environment.</p> <p>J. Biodivers. Conserv. Bioresour.

The seeds were categorized into apparently healthy seeds, black point seeds, and shriveled and undersized seeds. Variation in different parameters (viz.Grading, weight, purity percentage, germination and seedling growth) became evident among the varieties. Seed health test on blotters and agar plate method showed that the major fungi associated with healthy seeds and black point seeds were <em>Alternaria alternata</em>, <em>A. triticina</em>, <em>Bipolaris sorokiniana</em>, <em>B. tetramera</em>, <em>Curvularia lunata</em>, <em>Fusarium </em>spp., and species of <em>Aspergillus</em>. The incidence of <em>B. sorokiniana </em>increased with increasing severity of black point infection. Reduction in germination, seedling emergence, plant stand, root and shoot growth, and vigor index were directly related with the severity of black point. <em>Aspergillus </em>spp. were seen more frequently associated with non-germinated seeds.</p> <p>J.

Sampling is done monthly using the “Dipping” method to collect the mosquito larvae which were then transported to the laboratory for identification. Five mosquito species were collected in the surveyed site presented by 1035 individuals, these were <em>Culex pipiens, Culex theileri, Culex hortensis, Culex deserticola </em>and <em>Culiseta longiareolata </em>which appears to be the most abundant with three significant pullulation peaks. This inventory is supplemented by a physicochemical analysis of water to study the correlation between mosquito larval density and site water quality.</p> <p>J. Biodivers. Conserv. Bioresour.

A total of 304 tree species (both wild and planted) belonging to 201 genera under 69 families was recognized from the Chittagong University Campus flora. These species were categorized as angiosperms (297 species under 196 genera and 64 families) and gymnosperms (7 species under five genera and five families). Furthermore, the angiosperms were classified as dicot (95% species) and monocot (5% species). Among 69 families, top 10 families represented 47% of all species and remaining 59 families represented by 53% of the species. The study revealed that 12% of species were found in natural habitat, 32% in conservation programs, 20% both in natural and conservation areas, and 36% were exotics. Among 304 species, 13% were regarded as Vulnerable, 4% as Endangered and 3% as Critically Endangered, and collectively treated as threatened (20% of all recorded species). A checklist is prepared with updated nomenclature; each species is annotated with local name(s), family name, habitat, status of occurrence (wild/planted), and conservation status.</p> <p>J.

It was laid out in a completely randomized block design (CRBD) using 25 treatments having 3 replications each. Agronomic parameters of the growth and yield of tomato were recorded at 15, 30, 45, and 60 days interval. The highest growth and yield parameter found with 60 days. The tallest plant height (57 cm) was recorded in T<sub>13</sub>(N<sub>120</sub>P<sub>60</sub>K<sub>80</sub> kg ha<sup>-1</sup> + 2.5ton KWC ha<sup>-1</sup>). Highest number of leaf found (17 per plant) in T<sub>18</sub> (N<sub>30</sub>P<sub>15</sub>K<sub>20</sub> kg ha<sup>-1</sup> + 7.5 ton KWC ha<sup>-1</sup>) and T<sub>23</sub> (N<sub>60</sub>P<sub>30</sub>K<sub>40</sub> kg ha<sup>-1</sup> + 10 ton KWC ha1. The length of midrib (22 cm) inT<sub>3</sub> (5ton KWC ha<sup>-1</sup>) and dry weight of midrib (1.46 g plant<sup>-1</sup>) obtained topmost in T<sub>6</sub>(N<sub>30</sub>P<sub>15</sub>K<sub>20</sub> kg ha<sup>-1</sup>). The girth of plants (1.4 cm) in T<sub>14</sub>: (N<sub>30</sub>P<sub>15</sub>K<sub>20</sub> kg ha<sup>-1</sup> + 5 ton KWC ha<sup>-1</sup>, and leaf area (5.61 cm<sup>2</sup>) in T<sub>2</sub> (2.5 ton KWC ha<sup>-1</sup>). Total fresh weight of leaf, root and stem (60.3 g plant<sup>1</sup>) and dry weight of leaf, root and stem (21.91 g plant<sup>-1</sup>) were superior inT<sub>24</sub>(N<sub>90</sub>P<sub>45</sub>K<sub>60</sub> kg ha<sup>-1</sup> + 10 ton KWC ha<sup>-1</sup>), number of fruit per plant (10) inT<sub>5</sub>(10 ton KWC ha<sup>-1</sup>) and longest fruit (7.5 cm) inT<sub>5</sub>(10 ton KWC ha<sup>-1</sup>). Maximum fresh weight of tomato fruit (13.48 g plant<sup>-1</sup>) produces in T<sub>24</sub> (N<sub>90</sub>P<sub>45</sub>K<sub>60</sub> kg ha<sup>-1</sup> + 10 ton KWC ha<sup>-</sup><sup>1</sup>) and dry weight (5.32 g plant<sup>-1</sup>) in T<sub>20</sub> (N<sub>90</sub>P<sub>45</sub>K<sub>60</sub> kg ha<sup>-1</sup> + 7.5 ton KWC ha<sup>-1</sup>). The findings revealed that KWC with NPK T<sub>24</sub> (N<sub>90</sub>P<sub>45</sub>K<sub>60</sub> kg ha<sup>-1</sup> + 10 ton KWC ha<sup>-1</sup>) could be suggested to use for the maximum growth and yield of tomato. This trial has also been created the evidence that kitchen waste may be an alternative source of organic materials to produce tomato.</p> <p>J. Biodivers. Conserv. Bioresour.

The selected plants include <em>Detarium microcarpum, Daniela olivera, Vitallaria paradoxa and Entanda africana</em>. The various plant seeds were analysed for their proximate composition and the mean range values of moisture (5.09±0.24 to 6.73±1.11 g/100 g), ash (2.65±0.27 to 9.93±0.65 g/100 g), Crude fibres (1.24±0.10 to 6.75±0.37 g/100 g), crude protein (13.26±0.66 g/100 g), crude fat (8.72±0.42 to 16.00±0.68 g/100 g) and the calculated NFE range (54.53±0.27 g/100 g) were reported. Result revealed that all the plant seeds used were low in moisture contents an attributes for good storage and packaging for animal feed ratios. The qualitative analysis showed the presence of saponins, flavonoids, alkaloids, tannins, cardiac glycosides. Triterpenoids, quinine, sterols and traces of carbohydrate in <em>Vitellaria paradoxa </em>only. While phenol was not detected in all the plant seeds examined. The presence of saponins in all the plant seeds studied it is an indication that the seeds could be described as a potential source of natural antioxidants. This study therefore concluded that the phytochemical constituents revealed in some of the seed samples can be correlated with its medicinal properties used by traditional herbal healers around the study area.</p> <p>J.
