Abstract

The Greek ecosystems consist of a variety of plant species, of which a large percentage have aromatic and medicinal properties. Aromatic and medicinal plants play an important role in the health of people worldwide, especially in developing countries. The present review focuses on Sideritis spp. that is an important plant with an increased attention in the last years for its wide range of uses and especially due to its medicinal properties. The location and conditions of the areas that can be used for its cultivation should be similar to those of its natural habitat in order to keep the product quality. It is important to mention that both the yield and the lifetime of the crop depend to a large extent on cultivation care. Furthermore, it is noteworthy that Sideritis spp. fetch an auspicious potential for improvement of memory in healthy adults as well as in dementia patients. Currently, the demand for these plants and their derivatives has increased because they are natural, eco-friendly and generally recognized as safe products with high economic value. Therefore, it comprises an important commodity for extensive cultivation in Greece in the near future. Hence, this emphasizes the need of extensive study for reporting the additional information on the aromatic and medicinal importance of Sideritis spp.

Abstract

Croton species collected from the wild have always been used as herbal medicines for various diseases in Madagascar. The objective of this investigation was to review the ethnomedicinal uses, phytochemistry and biological activities of Croton species that are endemic to Madagascar. Relevant literature search was carried out using internet sources such as ACS, Web of Science, Wiley, SpringerLink, Scopus, Mendeley, Google Scholar, Pubmed, SciFinder, BioMed Central, Science Direct and Elsevier. Other literature sources were conference papers, book chapters, books, theses and websites. Literature sources revealed that leaves, bark, roots and twigs of Croton species are commonly used as traditional remedies for 38 human diseases and ailments in Madagascar. Cough, malaria, stomach problems, hypertension, asthma, colic and fever are the most commonly treated human diseases, including use of leafy branches of Croton species as insect and lice repellents. Phytochemical compounds isolated from Croton species include alkaloids, diterpenoids, essential oils, flavonoids, furanoditerpenoids and triterpenoids. Preliminary pharmacological studies indicate that crude extracts and compounds isolated from these species have antimicrobial and cytotoxic activities. In as much as the medicinal potential of Croton species should be evaluated, more intensive phytochemical and pharmacological assessments should be conducted to enhance the pharmaceutical potential of the species.

Abstract

There is no doubt that advances have been made and significant improvement reported on the application of orthodox therapies in the management and treatment of various acute and chronic diseases. However, different reports seem to show that orthodox therapies are restricted by mechanisms of action, which tend to focus on the symptoms of the disease instead of the main cause. On the other hand, throughout history, African traditional medicine (ATM) using products majorly from medicinal plants have been applied to alleviate symptoms of various diseases such as diabetes, hypertension, infertility, parasitic, bacterial, viral and fungal infections. Globally, information in respect of certain medicinal plants and their activities has been passed on from generation to generation. Fortunately, scientific studies have been able to confirm some of these claims and established the importance of medicinal plants in health care. Although African traditional medicine has contributed significantly to health care in Africa with over 80% of the population using African traditional medicine for their primary health service, it is faced with some challenges in term of its regulation and practice. Indiscriminate or non-regulated applications of various herbal medicines has put the health of people especially in African countries at the risk of toxicity or adverse effects or even death. It is for this reason that this paper examines the relevance of African traditional medicine, its regulation, the challenges associated with its regulation and the way forward.

Abstract

This paper reviews the importance of honey bee as pollinator of agriculture crops, fruit, vegetables, seeds etc. and losses in agriculture, honey bee and honey production due to use of chemical pesticides. Honey bee (Hymenoptera: Apidae) is economically important insect. Honeybees are existing all around world excluding extreme Polar Regions.  Honey bees (Apis mellifera) add approximately US $200 billion to the global economy every year, mainly through crop pollination. Productivity worth of pollination dependent crops equal to US$ 1590 million in Pakistan where 61 main pollinate crops are considered as foodstuff  (26 fruits, 19 vegetable, 7 oilseeds, 4 grain legumes, 2 flavoring crops and 3 nut shrubs) depend on  honey bee pollination. Honey bee population is declining with alarming speed all around the world and it is endangering global food security because one third of agriculture production depend upon on pollination particularly by honey bee. Current reduction in honey bee population for agriculture pollination is threatening to nuts, fruit, vegetable and seed production in Pakistan. Several factors responsible for decline of honey bee colonies including climate change, predation by other insects, air pollution, ecosemiotic collapse, the alteration of the bee microbiome, electromagnetic radiation from the sun, expose to initial life stress, nano materials, and biochemical pesticides, diseases, parasites surroundings of honey bees. The toxic chemicals are transported in hive through the pollen and nectar which may destroy the entire honey bee colony. Pesticides pattern applied in agriculture have been changed in last decade. This review research indicates how pesticide is used in agricultural crops for control of pests affecting on honey bee health and decline of bee populations. Then concludes with intensive studies on current management protocols would support in procedure formulation and resolution making polices regarding to shelter honey bees and management of pollination for agriculture purpose, which is lacking.

Abstract

Legumes (pulses) are ancient crops of the Sub-continent, Middle East and various parts of the Africa. These provide high quality protein and considered to be the best food for vegetarian population in India, South Asia, West Asia and Southern European countries. Chickpea is valued for its nutritive grains with high protein content of 25-29%. These grain legumes are, however, susceptible to different species of beetles of the family Bruchidae in storage commonly known as Dhora. At current, insect manage procedures frequently rely on synthetic insecticides and fumigants. Other than substance safety actions may be result as like numerous severe drawbacks. Insecticides have wide and unsystematic application causes natural imbalance confrontation to insect, insect recovery and epidemic of secondary insect creates phyto-toxicity. Insecticide residues in diet and nourish. Furthermore, non-stop use of insecticides leads to harmful result on insect pollination, biological agent like different Predators, parasitoids and too become cause of the ecological contamination. Owing to these drawbacks, internationally scientists are annoying to approve substitute methods of insect manage. The make use of close by obtainable native place resources in the management of harmful insects are a primeval technology.  Now in modern world, in numerous parts of the earth a range of crop of vegetation have been tried lately by researchers with an elevated amount of achievement as granule. Protestants next to pulse beetle to decrease plague in storage space. Observance these views in brain, the in attendance learning was conducted to examine the pesticide efficiency of a number of native botanicals powders as granule protestant next to Callosobruchus. chinensis legumes grains. Reviewed shows that different plant material which are friendly with ecosystems have significant results against pulse beetle and serve as an alternative methods for the pest control.
