Bioactivity of Chinese Insect Tea

Insect tea is a unique type of tea that differs from regular tea. Its production locations are primarily in rural areas of China inhabited by ethnic minorities, and its production mode is ethnically distinct. Kuding tea, Hawk tea, and fragrant leaves were obtained as fresh leaves from wild plants. Simple steaming reduced the astringency of […]

Accounts of Biological Functions for Accumulation of Radioisotopes in Fishes

The Fukushima Dai-ichi nuclear power plant in Fukushima-Ken (Prefecture), Japan, was destroyed in March 2011 by a major earthquake (magnitude 9) that struck off the northeast coast of Honshu Island, followed by a historic tsunami on March 11, 2011. Significant amounts of radioisotopes were released into the atmosphere and nearby seawater as a result of […]

Investigating the Effects of Host Grains on the Rice Weevil, Sitophilus oryzae (L.)

The present study was conducted to observe the effect of host preference on Sitophilus oryzae, the most cosmopolitan pest that causes severe losses in rice, maize, barley, wheat, on ovipsis, adult emergence, adult body length, longevity and sex ratio. Investigations into the production of S. were carried out. Oryzae in laboratory conditions on the four […]

A Comprehensive Review of Steroid Hormones in Reproduction and Roles of GnRH-a in Gonadal Maturation of Marine Fish

A series of hormones including gonadotropin-releasing hormones (GnRHs), gonadotropins (GTHs) and steroid hormones control the reproduction in teleosts. This literature review discusses the changes in steroid hormone levels in relation to sexual inversion, reproductive behaviour and gonadal growth, as well as the application of GnRH-a to induce marine fish maturation, in order to contribute to […]

Monitoring and Identification of Vietnamese Paphiopedilum Species Using Vegetative Morphology

Context: The use of floral morphology to discriminate against Paphiopedilum species has been used effectively and frequently because of the distinct characteristics of their reproductive parts. The definition of flower morphology and structure is also the subject of most classification references. Nevertheless, since unauthorised trade plants are often at non-flowered or plantlet levels, species protection […]

Jumping Plant-louse of the Genus Pseudoeriopsylla (Hemiptera-Psylloïdea-Homotomidae), Pest of Moraceae from Cameroon

In Cameroon, four species of Pseudoeriopsylla are known: P. laingi, P. etoundii, P. bitomi and P. mpoamei. The genus Pseudoeriopsylla is exclusively African and is distinguished by the presence of a pterostigma on the forewing and the absence of a costal split. In 1957, Eastop caught one species of P. laingi in a yellow trap […]

A Descriptive study on the Livelihood Status of Hilsa (Tenualosa ilisha) Fishermen of Greater Noakhali Regions of Bangladesh

During August 2014 to January 2015, the current study aimed to explain the livelihood status of Hilsa (Tenualosa ilisha) fishermen in Lakshmipur and Noahkali Districts in Bangladesh by means of a questionnaire survey tool. Pangas (Pangasius pangasius), Koral (Lates calcarifer) and Poa (Johnius coitor) were also found to be captured during Hilsa fishing, as by […]

An Assessmental Study on the Determination of Heavy Metals in Sediment of Fish Farms in Bangladesh

Despite scarce scientific work on revier sediemtn and fish in Bangladesh, heavy metal pollution of aquatic ecosystems is often most evident in sediments, but unfortunately no work has yet been published particularly on heavy metal contamination of fresh water fish farm sediments. In order to assess the environmental contamination of the selected fish farms in […]

Monitoring and Identification of Planktonic Genera/Species and Determination of the Physicochemical Factors Favoring the Growth of These Species in Cape 7 (Aftissat) Zone, South of Morocco

The research was carried out in the region of Cape 7 (Aftissat), south of Morocco, 232 km south of Laayoune. The goal is to define the planktonic genera/species and species 62 km south of Boujdour region. Determination of the physicochemical factors that favour these species’ development. The research was carried out by Carried out on […]

Assessment of Macrobenthic Community Structure: An Approach to Coastal Water Pollution in Bangladesh

The present study was planned to investigate the diversity of benthos in Bangladesh’s South-Western coastal waters with the following goals. A study was conducted during February-March 2015 on the assemblages of benthic macro faunal populations in the coastal areas of Bangladesh following the normal methods for assessing the environmental pollution status. The composition of macrobenthic […]
