The experiment was carried out with a randomized complete block design (RCBD) with 8 treatments and 3 replications. All the treatments significantly differed from the control. The total highest number and weight of healthy fruits were recorded in bagging (41.33 and 6.08 kg) but the lowest in control (19.00 and 2.22 kg, respectively). No infested fruits were found in bagging, meanwhile, the highest number and weight of infested fruits were counted in control (13.00 and 1.27 kg). In addition, bagging appeared to have no percent of infestation by number and weight. The highest percent of fruit infestation was found in control (40.75% and 36.48%) treatments based on number and weight. No wet reduction was found in the bagging treatment and the highest percent weight reduction per fruit was recorded in Ecomec 1.8 EC (30.17%). The highest number of larval densities were found in fruit fly bait with MSG (15.83) and the lowest in a yellow sticky trap set at 150 cm height (6.7). The highest number of fruit flies in a yellow sticky trap set at 50 cm height was captured on 21 March 2021 (4.33) and the lowest was on 29 April 2021 (1.33). The highest number of fruit flies were captured in a yellow sticky trap set at 50 cm height (43/trap) and the lowest in a bait trap with MSG (9.70/bait).

Four treatments, designated as T1, T2, T3, and T4 were used in the study, each with three replicates. The final weight of the prawns after 120 days of culture was highest in T1 (72.07 g) and lowest in T4 (50.23 g), but there was no significant difference in prawn growth between T1 and T2. In T4, where artificial feed was not employed, prawn, persa, and corsula mullet growth and survival rates were lower. T1 produced more prawns (173.27 kg ha-1), while T4 produced less (617.83 kg ha- 1). Significantly (p<0.05) higher production of persa was found in T1 (295.97 kg ha-1) and lower in T4 (152.28 kg ha-1). Corsula production was also observed to be higher in T1 (275.70 kg ha-1) and lower in T4 (155.36 kg ha-1).

The trial was conducted in the experimental field and laboratory of RSRC, BARI, from December 2020 to April 2021. Three released varieties (viz. BARI Morich 1, BARI Morich 2, and BARI Morich 3) and six genotypes (Viz. G10, G13, G25, G27, G30, and G31) were used as the test crops of the experiment. The findings showed a considerable amount of variation among the treatments. Regarding the number of mites/leaf, the G25 had the highest mean number (7.24) whereas the G31 had the lowest (0.69). The G30 was the most productive in terms of yield (512.27 g/plant). The weight of each fruit and the number of fruits per plant were directly related to yield. On the contrary, the G10 and the G13 supplied an optimum yield per plant, whereas the G25 produced the least yield (21.02/plant). The correlation between yield and mite infestation was negative, and the results revealed that the BARI Morich-1, the G27, and the G31 were highly resistant to chilli mite infestation, and the G13, the BARI Morich-3, and the G30 were resistant, while the BARI Morich-2 was only moderately resistant. The G10 was tolerant and the G25 was susceptible to chilli mite infestation.

However, the safety of the preparations is little understood. Parabens (alkyl esters of p-hydroxybenzoic acid) are widely used as preservatives in these pharmaceuticals. However, the presence of methylparaben in formulations raises anxiety due to its potential endocrine disruption functions. Endocrine disruption could lead to undesirable health abnormalities and carcinogenic, estrogenic, and adverse reproductive effects. The present investigation directs toward estimating of methylparaben in some anti-diabetic herbal preparations using UV- Vis spectrophotometric method abiding by International Conference on Harmonization (ICH) guidelines for validation. The analytical wavelength of methylparaben in methanol was determined and found at 256.5 nm. The method obeys Beer’s law in the analytical range and has a good coefficient of determination (r2= 0.9881). The limit of detection (LOD) and limit of quantification (LOQ) were 0.19 ppm and 0.57 ppm, respectively. Recoveries were 91.3-98.8% in analyte-free plant matrix and 91-105.8 % in a diluent. The coefficient of variation (CV%) varied between 0.005- 0.268% for different standards. Results of forty-eight anti-diabetic herbal preparations showed methylparaben was detected in thirty-four samples in the range of 13.12 – 325.13 mg/day with a mean exposure value of 78.25 mg/day. However, none of the samples raise concerns about safety (the safety ceiling for paraben is 420 mg/day). More investigation is required to determine, whether the herbal drugs are safe to consume in terms of methylparaben.\u0000J. Asiat. Soc.

Direct field observations were made from April 2020 to March 2021. In total, 109 species of birds belong to 18 orders, and 49 families were observed, with a total count of 5,453 individuals. Resident bird species (93 species, 85.32%) dominant in the study area, whereas the migratory species were only 16 (14.68%). The highest number of bird species (93 species, 85.32%) with the highest number of individuals (n=3171, 58.15%) was observed in Beleswar (rural site) area. Shannon diversity index value (H=3.89, Ds= 0.9724) was higher in the rural site than Madhukhali municipal area (urban site). In the winter season, the highest number of bird species (95 species, 87.15%) with the highest number of individuals (n=2303, 42.23%) was observed. Among micro-habitats, trees, particularly the native tree species, were the preferable sites for bird nesting, foraging, and roosting. Among birds, Acridotheres tristis was the most abundant species (n=316, 5.79%) in the study area, and an uneven distribution of species in the community structure was observed. The abundance of birds shows that 59 (54.12%) species were very common, 8 (7.33%) common, 9 (8.25%) uncommon, and 33 (30.27%) rare. Among the bird species, Ichthyophaga ichthyaetus was categorised as Near Threatened (NT), and the rest are Least Concerned (IUCN Bangladesh 2015). Illegal hunting of birds, especially waterbirds, is the major threat in the rural site.

A study was carried out at farmers’ papaya garden and homestead areas of 8 locations viz., Dumki, Bouphal, Dashmina, Patuakhali, Mirjagonj, Amtali, Kalapara and Kuakata of Patuakhali and Barguna districts of Bangladesh to observe the incidence, abundance, and damage potential of papaya mealybug, Paracoccus marginatus (Williams and Granara de Willink) from March to June 2019. An experiment consisting of seven treatments following randomized complete block design (RCBD) with three replications was conducted for controlling papaya mealybugs at Patuakhali Science and Technology University (PSTU) campus during March to June 2019. Results revealed that among 8 locations, the highest incidence of P. marginatus was recorded in June, and the lowest was in April. The maximum abundance of P. marginatus on leaves and fruits of the papaya plant was observed at Kolapara, and the lowest was at Amtali.
