New Insights Into the Microbiota of Moth Pests
International Journal of Molecular Sciences Review New Insights into the Microbiota of Moth Pests Valeria Mereghetti, Bessem Chouaia and Matteo Montagna * ID Dipartimento di Scienze Agrarie e Ambientali, Università degli Studi di Milano, 20122 Milan, Italy; [email protected] (V.M.); [email protected] (B.C.) * Correspondence: [email protected]; Tel.: +39-02-5031-6782 Received: 31 August 2017; Accepted: 14 November 2017; Published: 18 November 2017 Abstract: In recent years, next generation sequencing (NGS) technologies have helped to improve our understanding of the bacterial communities associated with insects, shedding light on their wide taxonomic and functional diversity. To date, little is known about the microbiota of lepidopterans, which includes some of the most damaging agricultural and forest pests worldwide. Studying their microbiota could help us better understand their ecology and offer insights into developing new pest control strategies. In this paper, we review the literature pertaining to the microbiota of lepidopterans with a focus on pests, and highlight potential recurrent patterns regarding microbiota structure and composition. Keywords: symbiosis; bacterial communities; crop pests; forest pests; Lepidoptera; next generation sequencing (NGS) technologies; diet; developmental stages 1. Introduction Insects represent the most successful taxa of eukaryotic life, being able to colonize almost all environments, including Antarctica, which is populated by some species of chironomids (e.g., Belgica antarctica, Eretmoptera murphyi, and Parochlus steinenii)[1,2]. Many insects are beneficial to plants, playing important roles in seed dispersal, pollination, and plant defense (by feeding upon herbivores, for example) [3]. On the other hand, there are also damaging insects that feed on crops, forest and ornamental plants, or stored products, and, for these reasons, are they considered pests. -
Gut Bacterial Communities of Two Insect Species Feeding on Toxic Plants Are Dominated by Enterococcus Sp

Meta-Omics Tools in the World of Insect-Microorganism Interactions
biology Review Meta-Omics Tools in the World of Insect-Microorganism Interactions Antonino Malacrinò Department of Physics, Chemistry and Biology (IFM), Linköping University, 58183 Linköping, Sweden; [email protected] or [email protected] Received: 25 October 2018; Accepted: 22 November 2018; Published: 27 November 2018 Abstract: Microorganisms are able to influence several aspects of insects’ life, and this statement is gaining increasing strength, as research demonstrates it daily. At the same time, new sequencing technologies are now available at a lower cost per base, and bioinformatic procedures are becoming more user-friendly. This is triggering a huge effort in studying the microbial diversity associated to insects, and especially to economically important insect pests. The importance of the microbiome has been widely acknowledged for a wide range of animals, and also for insects this topic is gaining considerable importance. In addition to bacterial-associates, the insect-associated fungal communities are also gaining attention, especially those including plant pathogens. The use of meta-omics tools is not restricted to the description of the microbial world, but it can be also used in bio-surveillance, food safety assessment, or even to bring novelties to the industry. This mini-review aims to give a wide overview of how meta-omics tools are fostering advances in research on insect-microorganism interactions. Keywords: metagenomics; metatranscriptomics; metaproteomics; microbiome; insect pests 1. Introduction It is widely acknowledged that microorganisms are the main drivers of several fundamental physical, chemical and biological phenomena [1]. As scientific techniques and instruments evolve, the role of microorganisms in shaping the lifestyle of other organisms becomes clearer. -

Sell Cut Flowers from Perennial Summer-Flowering Bulbs
SELL CUT FLOWERS FROM PERENNIAL SUMMER-FLOWERING BULBS Andy Hankins Extension Specialist-Alternative Agriculture, Virginia State University Reviewed by Chris Mullins, Virginia State University 2018 Commercial producers of field-grown flower cut flowers generally have a wide selection of crops to sell in April, May and June. Many species of annual and especially perennial cut flowers bloom during these three months. Many flower crops are sensitive to day length. Crops that bloom during long days such as larkspur, yarrow, peonies and gypsophila cannot be made to bloom after the summer equinox on June 21st. Other crops such as snapdragons may be day length neutral but they are adversely affected by the very warm days and nights of mid-summer. It is much more challenging for Virginia cut flower growers to have a diverse selection of flower crops for marketing from July to September when day length is getting shorter and day temperatures are getting hotter. Quite a few growers offer the same inventory of sunflowers, zinnias, celosia and gladiolas during the middle of the summer because everything else has come and gone. A group of plants that may offer new opportunities for sales of cut flowers during mid-summer are summer-flowering bulbs. Many of these summer-flowering bulbs are tropical plants that have only become available in the United States during the last few years. The first question that growers should ask about any tropical plant recommended for field planting is, " Will this species be winter hardy in Virginia?" Many of the bulb species described in this article are not very winter hardy. -

Current anatomical research in Liliaceae, Amaryllidaceae and Iridaceae. Telopea 2(4): 425-452, Fig.1-An annotated bibliography is presented covering literature over the period 1968 to date. Recent research is described and areas of future work are discussed. INTRODUCTION In this article, the literature for the past twelve or so years is recorded on the anatomy of Liliaceae, AmarylIidaceae and Iridaceae and the smaller, related families, Alliaceae, Haemodoraceae, Hypoxidaceae, Ruscaceae, Smilacaceae and Trilliaceae. Subjects covered range from embryology, vegetative and floral anatomy to seed anatomy. A format is used in which references are arranged alphabetically, numbered and annotated, so that the reader can rapidly obtain an idea of the range and contents of papers on subjects of particular interest to him. The main research trends have been identified, classified, and check lists compiled for the major headings. Current systematic anatomy on the 'Anatomy of the Monocotyledons' series is reported. Comment is made on areas of research which might prove to be of future significance. -

SUMMARY Developmental constraints have been proposed different characteristics of microsporogenesis, only cell to interfere with natural selection in limiting the available wall formation appeared as constrained. We show that set of potential adaptations. Whereas this concept has constraints may also result from biases in the correlated long been debated on theoretical grounds, it has been occurrence of developmental steps (e.g., lack of successive investigated empirically only in a few studies. In this article, cytokinesis when wall formation is centripetal). We document we evaluate the importance of developmental constraints such biases and their potential outcomes, notably the during microsporogenesis (male meiosis in plants), with an establishment of intermediate stages, which allow emphasis on phylogenetic patterns in Asparagales. Different development to bypass such constraints. These insights are developmental constraints were tested by character discussed with regard to potential selection on pollen reshuffling or by simulated distributions. Among the morphology.

His enthusiasm, erudite advice and friendship have proved invaluable in coming to terms with Langley. In a similar vein, I would like to thank Dr Vanessa Noble for assisting me with my earlier honours thesis. It was during this adventure that I developed the urge to tell Langley’s story. Secondly, I would also like to thank Jean Thomassen. This thesis would have never taken flight if it were not for her efforts in unearthing documents relating to Langley and putting me in contact with fellow members of the Langley family. Thirdly, I would like to thank Jackie Harris, Julia Martin, Michael Cope, and Jolyon and Michael Nuttall for the selfless way in which they shared stories and anecdotes relating to Langley with me.
