  • Fishing for Toxins
    000 - Applied Bio Systems Article 19/7/06 11:37 am Page 2 Fishing for Toxins ENVIRONMENTAL Professor Allan Cembella, Professor in the Faculty of Biology and Chemistry at the University of Bremen ANALYSIS and Head of Biological Sciences at the Alfred Wegener Institute. Email: [email protected] Abstract Researchers at the Alfred Wegener Institute (AWI) for Polar and Marine Research in Bremerhaven, Germany are applying advanced chemical and molecular biological technologies to answer ecological questions. They are analysing trace levels of natural bioactive substances in seawater and marine biotoxins produced by various phytoplankton (microalgae), bacteria and cyanobacteria (“blue- green algae”), trying to understand how these bioactive metabolites are produced and sequestered and what effects they have on the ecosystem. Allan Cembella, Professor in the Faculty of Biology and Chemistry at the University of Bremen and Head of Biological Sciences at AWI, describes how the division is using sophisticated chemical analytical technology, including liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS), and limited genomics approaches to define the genetic regulation of marine biotoxin production and eventually determine the distribution and functional ecology of these toxins in marine food webs. Introduction The Alfred Wegener Institute in Bremerhaven, named after the famous polar explorer and geomorphologist responsible for the continental drift theory, was established in 1980 as a research institute focusing primarily on the polar regions. Since then its mandate has enlarged to embrace other disciplines in marine and coastal research in temperate waters and global climate change studies. The Division of Biological Sciences at the Institute is involved in research on projects covering organismal biology, physiology and genetics, functional ecology, molecular biology, marine and natural products chemistry and, now, ecological chemistry - chemical aspects of biological and ecological processes and mechanisms.

  • Crab Spiders Impact Floral-Signal Evolution Indirectly Through Removal
    ARTICLE DOI: 10.1038/s41467-018-03792-x OPEN Crab spiders impact floral-signal evolution indirectly through removal of florivores Anina C. Knauer1, Moe Bakhtiari1,2 & Florian P. Schiestl1 The puzzling diversity of flowers is primarily shaped by selection and evolutionary change caused by the plant’s interaction with animals. The contribution of individual animal species to net selection, however, may vary depending on the network of interacting organisms. Here 1234567890():,; we document that in the buckler mustard, Biscutella laevigata, the crab spider Thomisus onustus reduces bee visits to flowers but also benefits plants by feeding on florivores. Uninfested plants experience a trade-off between pollinator and spider attraction as both bees and crab spiders are attracted by the floral volatile β-ocimene. This trade-off is reduced by the induced emission of β-ocimene after florivore infestation, which is stronger in plant populations where crab spiders are present than where they are absent, suggesting that plants are locally adapted to the presence of crab spiders. Our study demonstrates the context-dependence of selection and shows how crab spiders impact on floral evolution. 1 Department of Systematic and Evolutionary Botany, University of Zurich, Zollikerstrasse 107, 8008 Zurich, Switzerland. 2Present address: Institute of Biology, University of Neuchatel, Rue Emile-Argand 11, 2000 Neuchatel, Switzerland.

One possible alternative to chemical insecticides is biological pest control with the pteromalid wasp Lariophagus distinguendus against the weevils Sitophilus granarius, S. oryzae (Coleoptera: Dryophtoridae), and many other storage pest beetles. The use of this wasp as a biocontrol agent was already suggested in 1919 by Prof. Dr. Hase [1]. Despite many studies on host-finding and behavioral biology, the applied aspect was neglected until 1994. Nowadays the wasps are commercially available and can now even be reared on-site, facilitating their use tremendously. This review highlights the milestones in L. distinguendus research, gives insights in current studies, and ventures a glimpse into the future. Keywords: biological pest control; Pteromalidae; Lariophagus distinguendus; Sitophilus sp.; Stegobium paniceum; stored product protection 1. Introduction Stored grain is threatened by a vast number of storage pests, mostly insects [2]. Nowadays integrated pest management strategies (IPM) have superseded the excessive application of chemical insecticides used against storage pests in the past.

Concluding Remarks Acknowledgments Glossary Bibliography Biographical Sketch Summary In this chapter we describe the current state of tropical insect chemical ecology in Latin America with the aim of stimulating the use of this important tool for future generations of technicians and professionals workers in insect pest management. Sex pheromones of tropical insectsUNESCO that have been identified to– date EOLSS are mainly used for detection and population monitoring. Another strategy termed mating disruption, has been used in the control of the tomato pinworm, Keiferia lycopersicella, and the Guatemalan potato moth, Tecia solanivora. Research into other semiochemicals such as kairomones in tropical insects SAMPLErevealed evidence of their presence CHAPTERS in coleopterans. However, additional studies are necessary in order to confirm these laboratory results. In fruit flies, the isolation of potential attractants (kairomone) from Spondias mombin for Anastrepha obliqua was reported recently. The use of semiochemicals to control insect pests is advantageous in that it is safe for humans and the environment. The extensive use of these kinds of technologies could be very important in reducing the use of pesticides with the consequent reduction in the level of contamination caused by these products around the world.

Email: [email protected] (Received 24 June 2020; accepted 22 September 2020; first published online 13 November 2020) Abstract Although the use of nonhost plants intercropped among host crops has been a standard agricultural prac- tice for reducing insect herbivory for millennia, the use of nonhost signals to deter forest pests is much more recent, having been developed over the past several decades. Early exploratory studies with synthetic nonhost volatile semiochemicals led to targeted electrophysiological and trapping experiments on a variety of bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) across three continents. This work disclosed a suite of antennally and behaviourally active nonhost volatiles, which are detected in common across a range of coniferophagous bark beetles. It also established the fact that dispersing bark and ambro- sia beetles detect nonhost signals while in flight and avoid nonhost trees without necessarily landing on them. Later work showed that groups of synthetic nonhost volatiles, sometimes combined with insect- derived antiaggregants, are effective in protecting individual trees and forest stands.

  • Chemistry, Spectroscopic Characteristics and Biological Activity of Natural Occurring Cardiac Glycosides
    IOSR Journal of Biotechnology and Biochemistry (IOSR-JBB) ISSN: 2455-264X, Volume 2, Issue 6 Part: II (Sep. – Oct. 2016), PP 20-35 www.iosrjournals.org Chemistry, spectroscopic characteristics and biological activity of natural occurring cardiac glycosides Marzough Aziz DagerAlbalawi1* 1 Department of Chemistry, University college- Alwajh, University of Tabuk, Saudi Arabia Abstract:Cardiac glycosides are organic compounds containing two types namely Cardenolide and Bufadienolide. Cardiac glycosides are found in a diverse group of plants including Digitalis purpurea and Digitalis lanata (foxgloves), Nerium oleander (oleander),Thevetiaperuviana (yellow oleander), Convallariamajalis (lily of the valley), Urgineamaritima and Urgineaindica (squill), Strophanthusgratus (ouabain),Apocynumcannabinum (dogbane), and Cheiranthuscheiri (wallflower). In addition, the venom gland of cane toad (Bufomarinus) contains large quantities of a purported aphrodisiac substance that has resulted in cardiac glycoside poisoning.Therapeutic use of herbal cardiac glycosides continues to be a source of toxicity today. Recently, D.lanata was mistakenly substituted for plantain in herbal products marketed to cleanse the bowel; human toxicity resulted. Cardiac glycosides have been also found in Asian herbal products and have been a source of human toxicity.The most important use of Cardiac glycosides is its affects in treatment of cardiac failure and anticancer agent for several types of cancer. The therapeutic benefits of digitalis were first described by William Withering in 1785. Initially, digitalis was used to treat dropsy, which is an old term for edema. Subsequent investigations found that digitalis was most useful for edema that was caused by a weakened heart. Digitalis compounds have historically been used in the treatment of chronic heart failure owing to their cardiotonic effect.
