Simon R Leather Hon.FRES (13 March 1955 - 27 September 2021) [1] [2] was an entomologist in the UK, he was Professor of Entomology at Harper Adams University, Honorary Fellow of the Royal Entomological Society and an expert in aphids and applied entomology. [3]
Leather had a childhood interest in insects [4] and was educated at King George V School (Hong Kong) and Ripon Grammar School, he studied BSc Agricultural Zoology at the University of Leeds, graduating in 1977; and a PhD on the ecology of the bird cherry-oat aphid at the University of East Anglia, graduating in 1980. He was a Royal Society postdoctoral fellow in Finland, working on the bird cherry-oat aphid, he moved back to UEA and then worked at the Forestry Commission. [5]
In the early 1990s he moved the Silwood Park campus of Imperial College London to be a lecturer, rising to Reader in Applied Ecology, in 2012 Leather moved to Harper Adams University to be Professor of Entomology. [6]
Leather did extensive research into integrated pest management of insect pests in agriculture, horticulture and forestry [7] and he was a member of the UK government's Tree Health and Plant Biosecurity Taskforce. [8]
His work on aphids includes the discovery in pea aphids of cannibalistic behaviour. [9]
Leather has also carried out research in urban ecology, looking at the biodiversity value of roundabouts for over 10 years in Bracknell Forest. [10]
He was an advocate of the need for specialist training in entomology and taxonomy [11] and before his move to Harper Adams University was concerned that his then unique (in the UK) Masters courses in Entomology, Integrated Pest Management and Plant Pathology would cease on his eventual retirement. [12] In 2009 he coined the phrase 'institutional vertebratism' to describe the bias of scientific research funding to vertebrate animals, rather than the more numerous invertebrates. [13]
In late 2012 Leather joined Twitter with the account handle @entoprof [14] and in 2013 he started a personal blog Don't forget the roundabouts. He talked and wrote about new platforms for non-academic science communication that are available online. [15] [16]
Biological control or biocontrol is a method of controlling pests, whether pest animals such as insects and mites, weeds, or pathogens affecting animals or plants by using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs.
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs.
Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.
Frederick Vincent Theobald FES was an English entomologist and "distinguished authority on mosquitoes". During his career, he was responsible for the economic zoology section of the Natural History Museum, London, vice-principal of the South-Eastern Agricultural College at Wye, Kent, Professor of Agricultural Zoology at London University, and advisory entomologist to the Board of Agriculture for the South-Eastern district of England. He wrote a five volume monograph and sixty scientific papers on mosquitoes. He was recognised for his work in entomology, tropical medicine, and sanitation; awards for his work include the Imperial Ottoman Order of Osmanieh, the Mary Kingsley Medal, and the Victoria Medal of Honour, as well as honorary fellowships of learned societies.
Coccinellidae is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in Great Britain. Entomologists prefer the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval-shaped beetles with a domed back and flat underside. They are sexual dimorphic; adult females are larger than males. Many of the species have conspicuous aposematic colours and patterns, such as red with black spots, that warn potential predators that they are distasteful.
John Anthony Pickett CBE DSC FRS is a British chemist who is noted for his work on insect pheromones. Pickett is Professor of Biological Chemistry in the School of Chemistry at Cardiff University. He previously served as the Michael Elliott Distinguished Research Fellow at Rothamsted Research.
Erica McAlister Hon.FRES is an entomologist, museum curator and presenter in the United Kingdom. She is an expert in flies (Diptera) and is senior curator at the Natural History Museum, London. She is current President of the Amateur Entomologists' Society.
Charles Gordon Hewitt was a Canadian economic entomologist and pioneer of conservation biology. He was appointed dominion entomologist of Canada in 1909. He helped pass the Destructive Insect and Pest Act in 1910, and implemented significant changes in the Department of Agriculture. He published several books on the subjects of biology and entomology, and helped to further the 1916 treaty between Canada and the United States for the protection of migratory birds.
Hugh David Loxdale is an entomologist. He was professor of ecology at the Institute of Ecology, University of Jena from 2009 to 2010, president of the Royal Entomological Society from 2004 to 2006, and honorary visiting professor at the School of Biosciences, Cardiff University. Loxdale works on the population biology, ecology, and genetics of insects, especially aphids and their wasp parasitoids.
Lionel Roy Taylor was a British ecologist, president of the British Ecological Society 1984/85, and editor of the Journal of Animal Ecology.
Rhopalosiphum rufiabdominale, the rice root aphid or red rice root aphid, is a sap-sucking insect pest with a wide host range and a global distribution. As a member of the superfamily Aphidoidea, it is one of 16 species of the genus Rhopalosiphum. Adults and nymphs are soft-bodied and usually dark green with brown, red, or yellow tones. Like all aphids, reproduction is sexual and asexual, depending on the environmental conditions and host plant. Rice root aphids cause injury to external plant parts, namely the roots or stem, by feeding on plant sap and vector several important plant viruses. The hosts of this pest extend across multiple plant families with most belonging to Rosaceae, Poaceae, and Solanaceae. R. rufiabdominale is universally associated with Prunus species but also infests various field crops, greenhouse vegetables, cannabis, and other ornamental plants. While this aphid originates from east Asia, it spans nearly every continent. Dispersal is particularly widespread across the United States, India, and Australia, with crop damage documented in multiple instances, although economic losses are primarily associated with Japanese rice crops. Nonetheless, it remains a pest of serious concern due to its high mobility, discrete habitat, and adaptive plasticity, giving it the rightful reputation as a successful invader.
Adam Hart is an English scientist, author and broadcaster, specialising in ecology, entomology and conservation, especially in southern Africa. He has co-presented three BBC TV documentaries on social insects. Hart has written and presented numerous BBC Radio 4 and BBC World Service documentaries and written more than 120 scientific papers.
Louise M. Russell (1905-2009) was a US Department of Agriculture entomologist renowned for her expertise in insect identification and research on using parasites for biocontrol.
An increasing number of scientific studies are reporting substantial declines in insect populations worldwide. Most commonly, the declines involve reductions in abundance, though in some cases entire species are going extinct. The declines are far from uniform. In some localities, there have been reports of increases in overall insect population, and some types of insects appear to be increasing in abundance across the world.
