Molecular Basis of the Remarkable Species Selectivity of an Insecticidal
www.nature.com/scientificreports OPEN Molecular basis of the remarkable species selectivity of an insecticidal sodium channel toxin from the Received: 03 February 2016 Accepted: 20 June 2016 African spider Augacephalus Published: 07 July 2016 ezendami Volker Herzig1,*, Maria Ikonomopoulou1,*,†, Jennifer J. Smith1,*, Sławomir Dziemborowicz2, John Gilchrist3, Lucia Kuhn-Nentwig4, Fernanda Oliveira Rezende5, Luciano Andrade Moreira5, Graham M. Nicholson2, Frank Bosmans3 & Glenn F. King1 The inexorable decline in the armament of registered chemical insecticides has stimulated research into environmentally-friendly alternatives. Insecticidal spider-venom peptides are promising candidates for bioinsecticide development but it is challenging to find peptides that are specific for targeted pests. In the present study, we isolated an insecticidal peptide (Ae1a) from venom of the African spider Augacephalus ezendami (family Theraphosidae). Injection of Ae1a into sheep blowflies (Lucilia cuprina) induced rapid but reversible paralysis. In striking contrast, Ae1a was lethal to closely related fruit flies (Drosophila melanogaster) but induced no adverse effects in the recalcitrant lepidopteran pest Helicoverpa armigera. Electrophysiological experiments revealed that Ae1a potently inhibits the voltage-gated sodium channel BgNaV1 from the German cockroach Blattella germanica by shifting the threshold for channel activation to more depolarized potentials. In contrast, Ae1a failed to significantly affect sodium currents in dorsal unpaired median neurons from the American cockroachPeriplaneta americana. We show that Ae1a interacts with the domain II voltage sensor and that sensitivity to the toxin is conferred by natural sequence variations in the S1–S2 loop of domain II. The phyletic specificity of Ae1a provides crucial information for development of sodium channel insecticides that target key insect pests without harming beneficial species. -

Tarantulas and Social Spiders
Tarantulas and Social Spiders: A Tale of Sex and Silk by Jonathan Bull BSc (Hons) MSc ICL Thesis Presented to the Institute of Biology of The University of Nottingham in Partial Fulfilment of the Requirements for the Degree of Doctor of Philosophy The University of Nottingham May 2012 DEDICATION To my parents… …because they both said to dedicate it to the other… I dedicate it to both ii ACKNOWLEDGEMENTS First and foremost I would like to thank my supervisor Dr Sara Goodacre for her guidance and support. I am also hugely endebted to Dr Keith Spriggs who became my mentor in the field of RNA and without whom my understanding of the field would have been but a fraction of what it is now. Particular thanks go to Professor John Brookfield, an expert in the field of biological statistics and data retrieval. Likewise with Dr Susan Liddell for her proteomics assistance, a truly remarkable individual on par with Professor Brookfield in being able to simplify even the most complex techniques and analyses. Finally, I would really like to thank Janet Beccaloni for her time and resources at the Natural History Museum, London, permitting me access to the collections therein; ten years on and still a delight. Finally, amongst the greats, Alexander ‘Sasha’ Kondrashov… a true inspiration. I would also like to express my gratitude to those who, although may not have directly contributed, should not be forgotten due to their continued assistance and considerate nature: Dr Chris Wade (five straight hours of help was not uncommon!), Sue Buxton (direct to my bench creepy crawlies), Sheila Keeble (ventures and cleans where others dare not), Alice Young (read/checked my thesis and overcame her arachnophobia!) and all those in the Centre for Biomolecular Sciences. -

Academic Editor: Lourival D. Possani Received: 28 March 2017; Accepted: 28 April 2017; Published: 5 May 2017 Abstract: Many chemical insecticides are becoming less efficacious due to rising resistance in pest species, which has created much interest in the development of new, eco-friendly bioinsecticides. Since insects are the primary prey of most spiders, their venoms are a rich source of insect-active peptides that can be used as leads for new bioinsecticides or as tools to study molecular receptors that are insecticidal targets. In the present study, we isolated two insecticidal peptides, µ/!-TRTX-Mb1a and -Mb1b, from venom of the African tarantula Monocentropus balfouri. -
To Map Baboon Spider (Araneae: Theraphosidae) Distributions and Diversity in Southern Africa
The Baboon Spider Atlas – using citizen science and the ‘fear factor’ to map baboon spider (Araneae: Theraphosidae) distributions and diversity in Southern Africa Heather Campbell & Ian Engelbrecht Department of Zoology and Entomology, University of Pretoria, Pretoria, 0002, South Africa. Corresponding author email: [email protected] Abstract 1. Charismatic invertebrates are popular subjects for citizen science but it is harder to engage the public in research on animals that are perceived as dangerous. Many successful citizen science projects exist in North America and Europe, but with the increased use of new technologies and social media there is a greater capacity to expand citizen science to less developed regions. 2. Baboon spiders are African members of the tarantula family. They are threatened by habitat loss and illegal harvesting for the pet trade, but conservation efforts are hampered by a lack of knowledge on their ecology. 3. Here we describe the Baboon Spider Atlas, a project combining traditional research with citizen science to map the diversity and distributions of baboon spiders (Araneae: Theraphosidae) in Southern Africa. Our project embraces the ‘fear factor’ associated with spiders to obtain photographic records from the public. 4. The Baboon Spider Atlas has assembled the largest database of information on baboon spiders in Southern Africa and is providing novel insights into their biology. Distribution ranges have been extended and potential new species discovered. Preliminary results suggest that their distribution may be limited more by cold, wet climatic conditions than hot, dry conditions. Records for wandering adult females and immatures highlight a previously undocumented behaviour and challenges the notion that baboon spiders are sedentary 1 animals. -

Approximately 25 Mℓ/day of fissure water flows into the underground workings of the defunct Blyvooruitzicht Mine, which spans a strike of 6 km along the boundary with AGA. If dewatering at the Old Blyvooruitzicht Shafts (#4, #5 & 6#) shafts were to cease, uncontrolled fissure water would report to the AGA operations, which would pose both a flood and safety risk of AGA personnel and the mining operations. This report provides a professional opinion regarding the anticipated terrestrial, wetland and aquatic impacts from this proposed project. Location The proposed water pipeline and associated infrastructure is located approximately 80 km west of Johannesburg. It originates at CWC 4#, approximately 3.3 km south east of Carletonville and ends at the North Boundary Dam (NBD) approximately 6 km south-south-west of Carletonville in Blyvooruitzicht, Merafong City Local Municipality, West Rand District Municipality in the Gauteng Province of South Africa. -
Araneae (Spider) Photos
Araneae (Spider) Photos Araneae (Spiders) About Information on: Spider Photos of Links to WWW Spiders Spiders of North America Relationships Spider Groups Spider Resources -- An Identification Manual About Spiders As in the other arachnid orders, appendage specialization is very important in the evolution of spiders. In spiders the five pairs of appendages of the prosoma (one of the two main body sections) that follow the chelicerae are the pedipalps followed by four pairs of walking legs. The pedipalps are modified to serve as mating organs by mature male spiders. These modifications are often very complicated and differences in their structure are important characteristics used by araneologists in the classification of spiders. Pedipalps in female spiders are structurally much simpler and are used for sensing, manipulating food and sometimes in locomotion. It is relatively easy to tell mature or nearly mature males from female spiders (at least in most groups) by looking at the pedipalps -- in females they look like functional but small legs while in males the ends tend to be enlarged, often greatly so. In young spiders these differences are not evident. There are also appendages on the opisthosoma (the rear body section, the one with no walking legs) the best known being the spinnerets. In the first spiders there were four pairs of spinnerets. Living spiders may have four e.g., (liphistiomorph spiders) or three pairs (e.g., mygalomorph and ecribellate araneomorphs) or three paris of spinnerets and a silk spinning plate called a cribellum (the earliest and many extant araneomorph spiders). Spinnerets' history as appendages is suggested in part by their being projections away from the opisthosoma and the fact that they may retain muscles for movement Much of the success of spiders traces directly to their extensive use of silk and poison. -
