The knowledge on benthic fauna is important to know the biological interactions of the ecosystem. Abundance and composition of benthos along with some physico-chemical parameters of water of Rajdhalabeel, Netrokona was carried out from May 1998 to April 1999. The water parameters varied between or within the months but they did not vary from location to location. The benthic organisms had fluctuated both quantitatively and qualitatively. Considerable variation of benthos was detected during the period of the study. The composition of benthos were 38.26%, 29.86% and 25.22% for molluscs, oligochaetes and chironimids respectively. The highest number (1310.98 ind/m2) was recorded in July, 1998 while it was lowest (333.3 ind/m2) in April, 1999.The study revealed the beel as productive one and implementation of a little development work, good management and protect fishes from poaching may turn the beel into a very good fish resource.

Saint Martin's Island is the only island in Bangladesh where coral communities are found. An expedition on marine biodiversity monitoring of Saint Martin’s Island through underwater visual census method was carried out from December 2017 to March 2018. In this study, a total of 25 scleractinian coral species of 8 families and 14 genera were identified, of which 12 species, Dipsastraea lizardensis, Dipsastraea maritima, Dipsastraea veroni, Favites acuticollis, Favites melicerum, Favites pentagona, Goniastrea stelligera, Goniopora albiconus, Goniopora norfolkensis, Pavona clavus, Plesiastrea versipora, and Psammocora exesa were recorded for the first time in Bangladeshi marine water. These new records exemplify gaps in sampling and recording of coral species in Bangladesh, and suggest the need of extensive research on coral ecosystem in the country. Assessment of different valid reports and publications including the present study revealed that a total of 98 species of hard corals of 18 families and 37 genera have been reported until now in Saint Martin’s Island as well as Bangladesh.

This investigation was undertaken to evaluate some physico-chemical parameter of water of the trans-boundary Haora River in Brahmanbaria during October 2018 to September 2019 from three different sites. The study revealed that air temperature at three different sites ranged 13 – 38 °C while the water temperature was 11 – 32 °C. Transparency of water varied from 18 – 55 cm Secchi depth and became more turbid during monsoon. The average values of pH and dissolved oxygen (DO) both in sites and seasons were within the standard limits for aquatic organisms. Total dissolved solids (TDS) were found between 77 and 352 mg/L and varied greatly in seasons. Electric conductivity (EC) was ranged 135 to 650 μS/cm. On the other hand, maximum and minimum hardness of water were recorded as 322 mg/L and 118 mg/L respectively and become lowest in monsoon. The rainy season bear high torrential water which brought huge amount of different types of garbage through the water flow from the Indian part. Most of the garbage are of floating and submerged type as plastic containers, bottles, polybags, cans, etc along with natural debris. During the study period highest (172 kg) and lowest (113 kg) plastic garbage were collected in May and July respectively. This foreign garbage may impair the normal healthiness of the river ecology.

The experimental culture of 3 seaweed species, i.e. Hypnea musciformis, Enteromorpha intestinalis and Padina tetrastromatica in three locations of Cox’s Bazar coast, Bangladesh using 4×4 m horizontal coir rope net method were conducted during 2016 to 2018. Results showed that the biomass yield was highest from H. musciformis (30.23±0.40 kg fw m−1) and significantly differ from E. intestinalis (24.50±0.08 kg fw m−1) and P. tetrastromatica (10.18±0.45 kg fw m−1). The Daily Growth Rate (DGR) of H. musciformis (8.88% day−1) was also higher than the DGR of E. intestinalis (6.55% day−1) and P. tetrastromatica (6.74% day−1). Saint Martin’s Island showed higher biomass yield of seaweeds than Bakkhali and Inani due to favourable water quality. In context to physico-chemical parameters of seaweed farming, Cox's Bazar coast is suitable for seaweed cultivation, although more suitable culture areas and longer culture period yet to be identified. The findings of the present study suggest that the cultivation of H. musciformis is viable and coastal people can take up such activities as seasonal income generating activity in coastal water.

2016 - 2018年，在孟加拉国Cox 's Bazar海岸的三个地点，采用4×4 m水平椰绳网法进行了3种海藻(Hypnea musciformis、Enteromorpha intestalis和Padina tetrastromatica)的实验培养。结果表明，麻蝇的生物量产量最高(30.23±0.40 kg fw m−1)，显著高于肠螨(24.50±0.08 kg fw m−1)和四眼蝶(10.18±0.45 kg fw m−1)。musciformis的日生长率(DGR)为8.88% (d−1)，高于E. in肠(6.55%)和P. tetrastromatica(6.74%)。圣马丁岛由于良好的水质，其海藻生物量产量高于Bakkhali岛和Inani岛。从海藻养殖的理化参数来看，Cox's Bazar海岸适合海藻养殖，但更适合的养殖区域和更长的养殖周期尚未确定。本研究结果表明，在沿海水域养殖蝇蛆是可行的，沿海居民可以从事季节性创收活动。浙江大学学报(自然科学版)，49(1):47-56,2021

With global expansion of vector borne diseases, dengue has emerged as a big health crisis and social problem in recent years in Bangladesh. Despite its endemicity since 2000, very few studies were conducted outside of the Capital Dhaka city regarding vector breeding status. Within this dark situation, the year 2019 reported the ever highest number of dengue cases of 101,354. Of them about 50% were from out of Dhaka. To reduce this burden, keeping the vector population density under threshold level is must. In the present entomological study, 100 houses were checked randomly from five areas of Gazipur City Corporation (GCC) during the month of September in 2019. Both of the Aedes vectors were found in all areas, but Aedes aegypti population was dominant. Rooftop garden and under construction site were identified as the most important vector breeding sites. Highly urbanized area (SA2) produced the highest and suburban area (SA4) produced the lowest Breteau Index (BI) of 110 and 15 respectively. The overall House Index (HI) and Breteau Index (BI) of the study areas were 16 and 49 respectively. Four kinds of containers, namely; cemented tank, drum, big earthen pot (chari) and buckets contained about 80 percent of immature Aedes and identified as key container among the positive containers. The Said study has identified comparatively higher number of Ae. aegypti breeding, which is potential for triggering any major outbreak. Further, large-scale surveillance in all administrative wards with a larger sample may indicate the real picture of vector infestation situation throughout the municipality. Bangladesh J.

Pest management relies on proper identification of insect species, which usually depends on morphological keys. In this research, DNA barcoding was used to identify three pest species of genus Aulacophora (A. foveicollis, A. lewisii and A. indica) attacking horticultural crops in Bangladesh. Accurate phylogenetic information and evolutionary divergence data were supported and evidenced by various parameters, including the rates of substitution, nucleotide composition and genetic divergence. The nucleotide composition of these three species indicates that the total adenine and thiamine content (A+T, 67.3%) was higher than the guanine and cytosine content (G+C, 32.87%). Intraspecific genetic divergence ranged from 0.0158-0.1415. To confirm the origin and evolution, phylogenetic tree and haplotype network was drawn. Both the maximum likelihood and neighbor joining analyses showed that A. indica and A. foveicollis were clustered in one group, and A. lewisii was originated from another group. Haplotype showed that A. lewisii has the highest amount of mutational steps among the sequenced pests and genetically distant species from its common ancestors by 78 mutational numbers. Present investigation can be reliably treated for developing reference libraries for species identification via sequence matches and designing specific pest management approach. Bangladesh J.
