K. Ali1*, Nada F. Hemeda2 and Yasser F. Abdelaliem3 Abstract The subterranean termite Psammotermes hypostoma Desneux is considered as an important pest that could cause severe damage to buildings, furniture, silos of grain and crops or any material containing cellulose. This species of termites is widespread in Egypt and Africa. The lower termite’s ability to digest cellulose depends on the association of symbiotic organisms gut that digest cellulose (fagellates and bacteria). In this study, 33 diferent bacterial isolates were obtained from the gut of the termite P. hypostoma which were collected using cellulose traps. Strains were grown on carboxymethylcellulose (CMC) as a sole source of carbon. Cellulolytic strains were isolated in two diferent cellulose medium (mineral salt medium containing carboxymethylcellulose as the sole carbon source and agar cel- lulose medium). Five isolates showed signifcant cellulolytic activity identifed by a Congo red assay which gives clear zone. Based on biochemical tests and sequencing of 16s rRNA genes these isolates were identifed as Paenibacillus lactis, Lysinibacillus macrolides, Stenotrophomonas maltophilia, Lysinibacillus fusiformis and Bacillus cereus, that depos- ited in GenBank with accession numbers MG991563, MG991564, MG991565, MG991566 and MG991567, respectively.

  • Evaluation of the Chemical Defense Fluids of Macrotermes Carbonarius
    www.nature.com/scientificreports OPEN Evaluation of the chemical defense fuids of Macrotermes carbonarius and Globitermes sulphureus as possible household repellents and insecticides S. Appalasamy1,2*, M. H. Alia Diyana2, N. Arumugam2 & J. G. Boon3 The use of chemical insecticides has had many adverse efects. This study reports a novel perspective on the application of insect-based compounds to repel and eradicate other insects in a controlled environment. In this work, defense fuid was shown to be a repellent and insecticide against termites and cockroaches and was analyzed using gas chromatography-mass spectrometry (GC– MS). Globitermes sulphureus extract at 20 mg/ml showed the highest repellency for seven days against Macrotermes gilvus and for thirty days against Periplaneta americana. In terms of toxicity, G. sulphureus extract had a low LC50 compared to M. carbonarius extract against M. gilvus. Gas chromatography–mass spectrometry analysis of the M. carbonarius extract indicated the presence of six insecticidal and two repellent compounds in the extract, whereas the G. sulphureus extract contained fve insecticidal and three repellent compounds. The most obvious fnding was that G. sulphureus defense fuid had higher potential as a natural repellent and termiticide than the M. carbonarius extract. Both defense fuids can play a role as alternatives in the search for new, sustainable, natural repellents and termiticides. Our results demonstrate the potential use of termite defense fuid for pest management, providing repellent and insecticidal activities comparable to those of other green repellent and termiticidal commercial products. A termite infestation could be silent, but termites are known as destructive urban pests that cause structural damage by infesting wooden and timber structures, leading to economic loss.

Received: 28 December 2018; Accepted: 3 February 2019; Published: 8 February 2019 Abstract: Termites are social insects of economic importance that have a worldwide distribution. Identifying termite species has traditionally relied on morphometric characters. Recently, several mitochondrial genes have been used as genetic markers to determine the correlation between different species. Heavy metal accumulation causes serious health problems in humans and animals. Being involved in the food chain, insects are used as bioindicators of heavy metals. In the present study, 100 termite individuals of Anacanthotermes ochraceus were collected from two Saudi Arabian localities with different geoclimatic conditions (Riyadh and Taif). These individuals were subjected to morphological identification followed by molecular analysis using mitochondrial 12S rRNA gene sequence, thus confirming the morphological identification of A. ochraceus. Furthermore, a phylogenetic analysis was conducted to determine the genetic relationship between the acquired species and other termite species with sequences previously submitted in the GenBank database. Several heavy metals including Ca, Al, Mg, Zn, Fe, Cu, Mn, Ba, Cr, Co, Be, Ni, V, Pb, Cd, and Mo were measured in both collected termites and soil samples from both study sites.

In social insects. In termites, vibroacoustic and chemical alarm signalling many taxa, a wide range of defensive strategies have evolved helping are bound to operate synergistically but have never been studied organisms to deal with costs imposed by such interactions. Strategies simultaneously in a single species. Here, we inspected the functional consist in combining mechanical (biting, kicking, fleeing) and/or significance of both communication channels in Constrictotermes chemical (toxic or repellent compounds) arsenal with an effective cyphergaster (Termitidae: Nasutitermitinae), confirming the hypothesis alarm communication. The ability to give and perceive conspecific that these are not exclusive, but rather complementary processes. In signalling about imminent threats has attained maximum complexity natural situations, the alarm predominantly attracts soldiers, which in social groups, such as vertebrates (Manser, 2001, 2013) and insects actively search for the source of a disturbance. Laboratory testing (Blum, 1985; Hölldobler, 1999; Hölldobler and Wilson, 2009). revealed that the frontal gland of soldiers produces a rich mixture of In termites, one facet of such complexity is represented by the terpenoid compounds including an alarm pheromone.

  • Role of Arthropods in Maintaining Soil Fertility

Culliney Plant Epidemiology and Risk Analysis Laboratory, Plant Protection and Quarantine, Center for Plant Health Science and Technology, USDA-APHIS, 1730 Varsity Drive, Suite 300, Raleigh, NC 27606, USA; E-Mail: [email protected]; Tel.: +1-919-855-7506; Fax: +1-919-855-7595 Received: 6 August 2013; in revised form: 31 August 2013 / Accepted: 3 September 2013 / Published: 25 September 2013 Abstract: In terms of species richness, arthropods may represent as much as 85% of the soil fauna. They comprise a large proportion of the meso- and macrofauna of the soil. Within the litter/soil system, five groups are chiefly represented: Isopoda, Myriapoda, Insecta, Acari, and Collembola, the latter two being by far the most abundant and diverse. Arthropods function on two of the three broad levels of organization of the soil food web: they are plant litter transformers or ecosystem engineers. Litter transformers fragment, or comminute, and humidify ingested plant debris, which is deposited in feces for further decomposition by micro-organisms, and foster the growth and dispersal of microbial populations. Large quantities of annual litter input may be processed (e.g., up to 60% by termites). The comminuted plant matter in feces presents an increased surface area to attack by micro-organisms, which, through the process of mineralization, convert its organic nutrients into simpler, inorganic compounds available to plants. Ecosystem engineers alter soil structure, mineral and organic matter composition, and hydrology.

  • The Plasticity and Developmental Potential of Termites
    HYPOTHESIS AND THEORY published: 18 February 2021 doi: 10.3389/fevo.2021.552624 The Plasticity and Developmental Potential of Termites Lewis Revely 1,2*, Seirian Sumner 1* and Paul Eggleton 2 1 Centre for Biodiversity and Environmental Research, Department of Genetics, Evolution and Environment, University College London, London, United Kingdom, 2 Termite Research Group, Department of Life Sciences, The Natural History Museum, London, United Kingdom Phenotypic plasticity provides organisms with the potential to adapt to their environment and can drive evolutionary innovations. Developmental plasticity is environmentally induced variation in phenotypes during development that arise from a shared genomic background. Social insects are useful models for studying the mechanisms of developmental plasticity, due to the phenotypic diversity they display in the form of castes. However, the literature has been biased toward the study of developmental plasticity in the holometabolous social insects (i.e., bees, wasps, and ants); the hemimetabolous social insects (i.e., the termites) have received less attention. Here, we review the phenotypic complexity and diversity of termites as models for studying developmental plasticity. We argue that the current terminology used to define plastic phenotypes in social insects does not capture the diversity and complexity of these hemimetabolous social insects. We suggest that terminology used to describe levels of cellular potency Edited by: Heikki Helanterä, could be helpful in describing the many levels of phenotypic plasticity in termites.
