“…Heavy metals, pesticides, and even radiation alter most of the earth’s ecosystems. Therefore, many living organisms are used as models and bioindicators in the monitoring and assessing of the state of the environment and changes in ecosystems and provide warning signals for imminent ecological changes (Nouchi, 2012; Testi et al, 2012; Kalkan and Altuǧ, 2015; Parmar et al, 2016; Siddig et al, 2016). Among species that raise great interest in the field of ecosystem monitoring, beetles have started to attract attention as biological indicators of environmental contaminants (Zödl and Wittmann, 2003).…”

Beetles as Model Organisms in Physiological, Biomedical and Environmental Studies – A Review

Model organisms are often used in biological, medical and environmental research. Among insects, Drosophila melanogaster, Galleria mellonella, Apis mellifera, Bombyx mori, Periplaneta americana , and Locusta migratoria are often used. However, new model organisms still appear. In recent years, an increasing number of insect species has been suggested as model organisms in life sciences research due to their worldwide distribution and environmental significance, the possibility of extrapolating research studies to vertebrates and the relatively low cost of rearing. Beetles are the largest insect order, with their representative – Tribolium castaneum – being the first species with a completely sequenced genome, and seem to be emerging as new potential candidates for model organisms in various studies. Apart from T. castaneum , additional species representing various Coleoptera families, such as Nicrophorus vespilloides, Leptinotarsa decemlineata, Coccinella septempunctata, Poecilus cupreus, Tenebrio molitor and many others, have been used. They are increasingly often included in two major research aspects: biomedical and environmental studies. Biomedical studies focus mainly on unraveling mechanisms of basic life processes, such as feeding, neurotransmission or activity of the immune system, as well as on elucidating the mechanism of different diseases (neurodegenerative, cardiovascular, metabolic, or immunological) using beetles as models. Furthermore, pharmacological bioassays for testing novel biologically active substances in beetles have also been developed. It should be emphasized that beetles are a source of compounds with potential antimicrobial and anticancer activity. Environmental-based studies focus mainly on the development and testing of new potential pesticides of both chemical and natural origin. Additionally, beetles are used as food or for their valuable supplements. Different beetle families are also used as bioindicators. Another important research area using beetles as models is behavioral ecology studies, for instance, parental care. In this paper, we review the current knowledge regarding beetles as model organisms and their practical application in various fields of life science.

“…Air pollution monitoring by plants: Air pollutants affect the physiology of the plants which results in abnormal growth. Plants respond variably to different pollutants individually and in combination (Emberson et al, 2001).Sensitive plants behave as early warning system and can be used to assess the extent of pollution in the milieu (Nouchi, 2002). Air pollution can be defined as the fluctuation in any atmospheric constituent from the value that would have existed without human intervention and is considered as one of the most serious problems the world is facing today.…”

Air pollution is a global phenomenon arising out of the unsustainable, unplanned and rapid develop-ment. The quality of air is deteriorating day by day because of rising concentrations of various gases in the atmos-phere. Presently, no such system has been developed ever that completely eliminates air pollutants, but nature has created many systems to deal with the harmful results of different anthropogenic activities up to a certain limit. Some plants can survive well with higher pollutant concentrations and act as pollution scavenger. Green plants act as a sink and filter to minimize air pollution by absorption, adsorption, detoxification, accumulation and/or metabolization without sustaining serious decline in growth, thus improving air quality by providing oxygen to the atmosphere. The plants which can withstand higher pollutant concentrations can serve as tolerant species and may be suggested to act as pollution scavengers. In the present study the air pollution tolerance index of some plants has been reviewed which are widely distributed throughout India and may prove helpful for the abatement of elevated air pollution levels such as Mangifera indica, Azardirachta indica, Saraca indica, Ficus religiosa, Ficus benghalensis, Shorea robusta and Bougainvillea spp. The wild indigenous species are superior performers in air pollution reduction as compared to the cultivated non indigenous species. The screening out of tolerant plant species from the sensitive ones can provide a database which may help landscapers to design green belts around industries and National Highways.

“…For example, sentinel plants have been used to provide adequate warning for damage downy mildew on cucurbit crops, and roses planted at the end of vineyard rows can give an early warning for problems with powdery mildew. In addition, some sentinel plants, are used as indicators of air pollutants (Nouchi 2002).…”

The number of invasive alien pest and pathogen species affecting ecosystem functioning, human health and economies has increased dramatically over the last decades. Discoveries of invasive pests and pathogens previously unknown to science or with unknown host associations yet damaging on novel hosts highlights the necessity of developing novel tools to predict their appearance in hitherto naïve environments. The use of sentinel plant systems is a promising tool to improve the detection of pests and pathogens before introduction and to provide valuable information for the development of preventative measures to minimize economic or environmental impacts. Though sentinel plantings have been established and studied during the last decade, there still remains a great need for guidance on which tools and protocols to put into practice in order to make assessments accurate and reliable. The sampling and diagnostic protocols chosen should enable as much information as possible about potential damaging agents and species identification. Consistency and comparison of results are based on the adoption of common procedures for sampling design and sample processing. In this paper, we suggest harmonized procedures that should be used in sentinel planting surveys for effective sampling and identification of potential pests and pathogens. We also review the benefits and limitations of various diagnostic methods for early detection in sentinel systems, and the feasibility of the results obtained supporting National Plant Protection Organizations in pest and commodity risk analysis.
