Dr. Hans Dietrich Reckhaus (2019): Insect Respect.
9th, revised edition

«Das Gütezeichen für einen neuen Umgang mit Insekten.» Gais, Bielefeld: Insect Respect.

The documentation about Insect Respect introduces the quality seal and offers insight into the organisation's origins: In 2011, instigated by the conceptual artists Frank and Patrik Riklin, the biocide entrepreneur Dr. Hans-Dietrich Reckhaus asked himself «What's the value of a fly?». Their response: Save, don't kill. Thus, the idea of a scientific model was born which calculates insect loss through biocides for home use and to compensate the loss by establishing insect-friendly habitats outdoors. This book explains the philosophy and model and makes Insect Respect's concrete activities visible through which the organisation sensitises society for the value and benefit of Insects.

The author Dr. Hans-Dietrich Reckhaus ist CEO of Reckhaus GmbH & Co. KG in Bielefeld (Germany) and of Reckhaus AG in Gais (Switzerland). For 60 years the company has been specialised in development and production of insect control products. By founding Insect Respect, the company starts its transformation from a manufacturer of chemical products towards a supplier of ecological services.

The book can be bought postage-free (DACH region) in the internet shop. It is available in German only.

Insect Respect (2019): Conference documentation „Day of Insects Germany 2019“

What can we do to protect insects? For this question the Museum für Naturkunde Berlin and Insect Respect co-operated. All visitors of the research museum were invited to dive into the insects universe on the Day of Insects. On top of that, conference participants got many impulses on the topics of insect protection and insect decline. For example, the museum's general director, Prof. Johannes Vogel, stated that it is putting lipstick on a pig to say it is high time to do something about insect decline. Researchers and entrepreneurs presented their results and projects and motivated the participants to network and take action for insects. The event was, among others, supported by the REWE Group, the hk group, AIM, Europarc Germany and HektarNektar.

The multimedial conference documentation summarises the congress in photos, quotations and short articles. Furthermore, the presentation videos and power point slides are hyperlinked there.

Anniversary brochure:
10 years 'Biodiversity in Good Company' initiative

Because of Reckhaus' commitment to saving insects with Insect Respect the company became a member of the 'Biodiversity in Good Company' initiative. The members are companies, such as REWE, Ritter Sport and HeidelbergCement, which consistently champion biodiversity protection and conservation. The anniversary brochure was published in late 2018. It shows milestones of the members' best practice examples from the last decade, among others from Reckhaus.

Svenja Schulze, Federal Minister for the Environment, congratulated on the initiative's 10 year anniversary: "I appreciate it very much that the member companies fight for an economy which respects the limits of nature and environment. They live up to their societal responsibility and show with practical examples the different possibilities companies have when it comes to protecting biodiversity. This deserves respect and encourages imitation!"

Promote insects with expertise

The Insect Respect team relies on the expertise of biologist Dr. Philipp Unterweger. His scientific research focuses on the social acceptance of conservation measures and the connection between grassland management and insect populations. The results of his research help to improve green areas through adapted care and optimised marketing. In this way insect dying can be reduced and biological diversity increased. In his award-winning research project "Initiative Bunte Wiese", Dr. Philipp Unterweger combined the practical approaches of a non-governmental organisation (NGO) with the scientific issues of biodiversity and social research.

An overview of the publications of Dr. Philipp Unterweger can be found here.

Dr. Hans Dietrich Reckhaus (2017): Why every fly counts.

A Documentation about the Value and Endangerment of Insects. Springer Verlag, ISBN 978-3-319-58765-3.

"Warum jede Fliege zählt“ was published in English by Springer publishing house under the title „Why Every Fly Counts“ in summer 2017.

"The publications of Insect Respect are unique: They do not discuss single aspects like biotechnology or beneficial insects or pests, they rather show the important role of this animal group in the whole balance of ecosystems. This kind of literature really bridges a gap in the market."     

Prof. Dr. Stanislav N. Gorb, Zoological Institute, Functional Morphology and Biomechanics, Kiel University

"This is an important book in the age of unrestrained bees and insects dying. It is based on well investigated examples and demonstrates the importance of insects in their various functions for life on this planet as well as the fact that they can be unpleasent for humans. Thus their benefits for humans and ecosystems are presented as well as the dangers, which they can cause in their role as disease carriers or parasites for humans. Insects play a key role in the fine-tuned processes and the resilience of ecological processes that are essential for the preservation of an environment beneficial to human beings. However this balance was destroyed by human activities, such as the industrialized agriculture, where large amounts of insecticides are used. This book is not just an appeal to change our behaviour: In another publication (title: „Insect Respect“) the author points out ways to handle this challenge."     

Dr. Angelika Hilbeck, Swiss Federal Institute of Technology, Institute of Integrative Biology IBZ, ETH Zürich

Dr. Hans-Dietrich Reckhaus (2017): Kleine Riesen – Von Insekten, Kunst und Respekt.

In: Hildebrandt, Alexandra (Ed.): CSR und Digitalisierung.
Digital transformation: chances and challenges for economy and society. Berlin: Springer publishing house, p. 575-591.

For the Springer editor’s volume "CSR und Digitalisierung" Insect Respect contributed an article under the heading "Little Giants – About Insects, Art and Respect". But what is actually the correlation between digitization, corporate social responsibility (CSR) and insects dying? The authors Dr. Hans-Dietrich Reckhaus und Tina Teucher do ask this very question in their text. To pursue this, they tell the adventure trip of the company Reckhaus. This journey began with the door opening for the art: The company experienced a supposedly absurd fly-rescue action, initiated a detailed scientific study of nature, biodiversity and sustainability, leading to the transformation of the entire business model. It’s a story about the quest for truth, rethinking and change. In the Springer book the editors gather numerous contributions and forewords, among others by Wolfgang Schäuble, Fredmund Malik, Timothy Hottges, Henning Kagermann, Bert Rürup, Christian Seifert, Tim Leberecht, Dieter Gorny, Christoph Keese and Valerie Niehaus, showing the need of a new way of thinking to understand and shape tomorrow’s world. If a community keeps operating too long with an outdated operating system, an end up in social unrest, competition over resources, war, isolation of the elite and authoritarian ruling systems could be destined.
