The list includes records before 1992, which have been published in previous papers, as well as data from an almost ten-year survey using Rothamsted suction traps and Moericke traps. The recorded aphidofauna consisted of 301 species. The family Aphididae is represented by 13 subfamilies and 120 genera (300 species), while only one genus (1 species) belongs to Phylloxeridae. The aphid fauna is dominated by the subfamily Aphidi- nae (57.1 and 68.4 % of the total number of genera and species, respectively), especially the tribe Macrosiphini, and to a lesser extent the subfamily Eriosomatinae (12.6 and 8.3 % of the total number of genera and species, respectively). -

This information is not only important for conservation efforts, but also has important implications for sustainable agricultural practices. Associated biodiversity can provide ecosystem services like pollination and pest control, but because organisms may respond differently to the unique environmental filters of specific urban landscapes, it is valuable to compare regions that have different abiotic conditions and urbanization histories. In this study, we compared the abundance and diversity of ladybird beetles within urban gardens in California and Michigan, USA. We asked what species are shared, and what species are unique to urban regions. Moreover, we asked how beetle diversity is influenced by the amount and rate of urbanization surrounding sampled urban gardens. We found that the abundance and diversity of beetles, particularly of unique species, respond in opposite directions to urbanization: ladybirds increased with urbanization in California, but decreased with urbanization in Michigan. -

As part of the environmental safety assessment of MIR604 maize, risks to non-target organisms of mCry3A were assessed. The potential exposure of non-target organisms to mCry3A following cultivation of MIR604 maize was determined, and the hypothesis that such exposure is not harmful was tested. The hypothesis was tested rigorously by making worst-case or highly conservative assumptions about exposure, along with laboratory testing for hazards using species taxonomically related to the target pest and species expected to have high exposure to mCry3A, or both. Further rigour was introduced by study designs incorporating long exposures and measurements of sensitive endpoints. No adverse effects were observed in any study, and in most cases exposure to mCry3A in the study was higher than the worst-case expected exposure. In all cases, exposure in the study was higher than realistic, but still conservative, estimates of exposure. These results indicate minimal risk of MIR604 maize to non-target organisms. Key words: environmental safety, exposure, hazard, hypothesis testing, transgenic plants 1 Introduction Control of corn rootworms requires insecticides or crop rotation, and both methods can occasionally fail Corn rootworms are serious pests of maize in the USA, to prevent yield loss because of adaptation of the pest where they cause estimated annual losses of 1 billion (Rice 2003). -

Arthropod Communities and Transgenic Cotton in the Western United States: Implications for Biological Control S.E
284 Naranjo and Ellsworth ___________________________________________________________________ ARTHROPOD COMMUNITIES AND TRANSGENIC COTTON IN THE WESTERN UNITED STATES: IMPLICATIONS FOR BIOLOGICAL CONTROL S.E. Naranjo1 and P.C. Ellsworth2 1U.S. Department of Agriculture, Agricultural Research Service, Phoenix, Arizona, U.S.A. 2University of Arizona, Maricopa, Arizona, U.S.A. INTRODUCTION Cotton, transgenically modified to express the insecticidal proteins of Bacillus thuringiensis (Bt), has been available commercially in the United States since 1996. Bt cotton is widely used throughout the cotton belt (Layton et al., 1999), and more than 65% of the acreage in Arizona has been planted to Bt cotton since 1997. In the low desert production areas of Arizona and California, Pectinophora gossypiella (Saunders), the pink bollworm, is the major target of Bt cotton. A number of other lepidopterous species occur in this area, but they are sporadic secondary pests of cotton whose population outbreaks are typically induced by indiscriminate use of broad-spectrum insecticides. As a result of the adoption of Bt-cotton and the coincident introduction and adoption of selective insect growth regulators for suppression of Bemisia tabaci (Gennadius), insecticide usage in Arizona cotton over the past decade as declined from a high of 12.5 applications per acre in 1995 to 1.9 in 1999 (Ellsworth and Jones, 2001). These reductions in insecticide use have broadened opportunities for all biological control approaches in cotton. Beyond concern for the maintenance of susceptibility in target pest populations there also are a number of ecological and environmental questions associated with use of transgenic crops, one of the most prominent being effects on non-target organisms. -
Rnai of Selected Insect Genes

Ilze Visser December 2016 Copyright © 2016 Stellenbosch University All rights reserved ii Stellenbosch University https://scholar.sun.ac.za Abstract Diuraphis noxia (Kurdjumov, Hemiptera: Aphididae), commonly known as the Russian wheat aphid (RWA), is regarded as one of the most destructive and widely distributed insect species in the world. Nonetheless, the currently available control strategies, including chemical pesticides, biological control agents, and RWA resistant wheat cultivars, are still very limited and rather ineffective. The process of double-stranded RNA (dsRNA)-mediated interference (RNAi) displays high specificity and the prospect of developing into a new specific method for managing agricultural pests. Plants can potentially be genetically engineered to express dsRNA to down-regulate vital gene functions present in pest insects, resulting in the protection of plants. In order to survive and reproduce, aphids require close interaction with their host plants, during which effectors are transported inside the plant to modify host cell processes. -
Wikipedia Beetles Dung Beetles Are Beetles That Feed on Feces
Wikipedia beetles Dung beetles are beetles that feed on feces. Some species of dung beetles can bury dung times their own mass in one night. Many dung beetles, known as rollers , roll dung into round balls, which are used as a food source or breeding chambers. Others, known as tunnelers , bury the dung wherever they find it. A third group, the dwellers , neither roll nor burrow: they simply live in manure. They are often attracted by the dung collected by burrowing owls. There are dung beetle species of different colours and sizes, and some functional traits such as body mass or biomass and leg length can have high levels of variability. All the species belong to the superfamily Scarabaeoidea , most of them to the subfamilies Scarabaeinae and Aphodiinae of the family Scarabaeidae scarab beetles. As most species of Scarabaeinae feed exclusively on feces, that subfamily is often dubbed true dung beetles. There are dung-feeding beetles which belong to other families, such as the Geotrupidae the earth-boring dung beetle. The Scarabaeinae alone comprises more than 5, species. The nocturnal African dung beetle Scarabaeus satyrus is one of the few known non-vertebrate animals that navigate and orient themselves using the Milky Way. Dung beetles are not a single taxonomic group; dung feeding is found in a number of families of beetles, so the behaviour cannot be assumed to have evolved only once. Dung beetles live in many habitats , including desert, grasslands and savannas , [9] farmlands , and native and planted forests. They are found on all continents except Antarctica. They eat the dung of herbivores and omnivores , and prefer that produced by the latter. -

Characterization of the Mitochondrial Genomes of Diuraphis Noxia Biotypes
Characterization of the mitochondrial genomes of Diuraphis noxia biotypes By Laura de Jager Thesis presented in partial fulfilment of the requirements for the degree Magister Scientiae In the Faculty of Natural and Agricultural Science Department of Genetics University of Stellenbosch Stellenbosch Under the supervision of Prof. AM Botha-Oberholster December 2014 Stellenbosch University http://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: . 25 December 2014. Copyright 2014 Stellenbosch University All rights reserved ii Stellenbosch University http://scholar.sun.ac.za Abstract Diuraphis noxia (Kurdjumov, Hemiptera, Aphididae) commonly known as the Russian wheat aphid (RWA), is a small phloem-feeding pest of wheat (Triticum aestivum L). Virulent D. noxia biotypes that are able to feed on previously resistant wheat cultivars continue to develop and therefor the identification of factors contributing to virulence is vital. Since energy metabolism plays a key role in the survival of organisms, genes and processes involved in the production and regulation of energy may be key contributors to virulence: such as mitochondria and the NAD+/NADH that reflects the health and metabolic activities of a cell. The involvement of carotenoids in the generation of energy through a photosynthesis- like process may be an important factor, as well as its contribution to aphid immunity through mediation of oxidative stress. -
Integrative Taxonomy Reveals Hidden Species Within a Common Fungal Parasite of Ladybirds Received: 19 April 2018 Danny Haelewaters 1,2, André De Kesel3 & Donald H
www.nature.com/scientificreports OPEN Integrative taxonomy reveals hidden species within a common fungal parasite of ladybirds Received: 19 April 2018 Danny Haelewaters 1,2, André De Kesel3 & Donald H. Pfster1 Accepted: 8 October 2018 Our understanding of fungal diversity is far from complete. Species descriptions generally focus on Published: xx xx xxxx morphological features, but this approach may underestimate true diversity. Using the morphological species concept, Hesperomyces virescens (Ascomycota, Laboulbeniales) is a single species with global distribution and wide host range. Since its description 120 years ago, this fungal parasite has been reported from 30 species of ladybird hosts on all continents except Antarctica. These host usage patterns suggest that H. virescens could be made up of many diferent species, each adapted to individual host species. Using sequence data from three gene regions, we found evidence for distinct clades within Hesperomyces virescens, each clade corresponding to isolates from a single host species. We propose that these lineages represent separate species, driven by adaptation to diferent ladybird hosts. Our combined morphometric, molecular phylogenetic and ecological data provide support for a unifed species concept and an integrative taxonomy approach. What is a species? Tis is a perennial question in evolutionary biology. Te answer is complex and has been intensely argued for decades. Diferent species concepts corresponding to multiple biological properties pro- vide a means to recognize, delineate and describe species. Tese properties include diferences in morphological traits, nucleotide divergence and monophyly, reproductive isolation, ecological niches or adaptive zones, mate recognition or mating systems, geographic range, exclusive coalescence of alleles, etc. However, biologists from various research felds have advocated diferent and sometimes incompatible species concepts, leading to varying conclusions regarding delimitation of species and their numbers.
