Accelerating entomology with Web3D insects

Capturing high-quality 3D models of insects is challenging - they are usually too small for laser or depth camera based systems, and techniques such as CT scanning do not record color. We have developed a prototype system that generates unprecedentedly high-quality natural-color 3D models of various insects from 3mm to 30 mm in length. Through the use of 3D web standards we are able to use these models to develop novel applications for entomologists and ensure wide accessibility. © 2014 Authors.

Sigastus weevil - an emerging pest of macadamias in north Queensland

A large weevil was found infesting macadamia nuts on the Atherton Tableland during the 1994/95 season. It was unrepresented in various Australian insect collections but thought to belong to the genus Sigastus. This paper reports some preliminary studies on its biology, pest status and control. From 4-6 weeks after first nut-set adult females commence laying single eggs through the husk, after first scarifying an oviposition site. The nut stalk is then cleaved leading to rapid abscission. Nuts were generally attacked up until hard shell formation. Weevil larvae consumed whole kernels, with % survival higher and larval duration shorter in larger nuts. Infestation rates increased with increasing nut diameter, reaching 72.8% of fallen nuts by mid-October. A crop loss of 30% could be attributed to weevils in an unsprayed orchard. However, adult weevils are very susceptible to both carbaryl and methidathion sprays. In addition, exposure of infested nuts to full sunlight over several weeks kills 100% of larvae. Crops should be surveyed for weevil damage from the 5-10 mm diameter stage until mid-December. Methidathion used as an initial spray for fruitspotting bugs should provide control. Organic growers are advised to sweep infested nuts into mown interrows where solarisation will kill larvae.

Facilitating IPM adoption in northern region broadacre farming systems

The principal aim of the project was to contribute to the continuing adoption of integrated pest management (IPM) by grain growers in the GRDC's northern region, specifically, the Darling Downs and Central Queensland. This project provided an ongoing commitment to the development and refinement of pest management tactics, and continued support for the grower community by raising awareness of management options and strategies for their implementation. This outcome was achieved through facilitated learning by growers and their advisers via grower group meetings, field day demonstrations, technical literature and presentations by entomologists at technical forums.

“Islands” in Holocene forests: implications for forest openness, landscape clearance and “culture-steppe” species

Human activity has undoubtedly had a major impact on Holocene forested ecosystems, with the concurrent expansion of plants and animals associated with cleared landscapes and pasture, also known as 'culture-steppe'. However, this anthropogenic perspective may have underestimated the contribution of autogenic disturbance (e.g. wind-throw, fire), or a mixture of autogenic and anthropogenic processes, within early Holocene forests. Entomologists have long argued that the north European primary forest was probably similar in structure to pasture woodland. This idea has received support from the conservation biologist Frans Vera, who has recently strongly argued that the role of large herbivores in maintaining open forests in the primeval landscapes of Europe has been seriously underestimated. This paper reviews this debate from a fossil invertebrate perspective and looks at several early Holocene insect assemblages. Although wood taxa are indeed important during this period, species typical of open areas and grassland and dung beetles, usually associated with the dung of grazing animals, are persistent presences in many early woodland faunas. We also suggest that fire and other natural disturbance agents appear to have played an important ecological role in some of these forests, maintaining open areas and creating open vegetation islands within these systems. More work, however, is required to ascertain the role of grazing animals, but we conclude that fossil insects have a significant contribution to make to this debate. This evidence has fundamental implications in terms of how the palaeoecological record is interpreted, particularly by environmental archaeologists and palaeoecologists who may be more interested in identifying human-environment interactions rather than the ecological processes which may be preserved within palaeoecological records.

Determinación de los efectos en la salud de los trabajadores del programa de control de vectores expuestos laboralmente a organoclorados en tres departamentos de Colombia 2013

Objetivo: Evaluar la exposición a plaguicidas organoclorados empleados en salud publica en la población trabajadora del programa de control de vectores en tres regiones de Colombia en 2013. Métodos: Se realizó un estudio descriptivo de corte transversal en el grupo de trabajadores del programa de control de enfermedades transmitidas por vectores -ETV- (coordinadores, técnicos, entomólogos, técnicos y auxiliares) de los departamentos de Meta, Nariño y Risaralda. A todos los participantes se les realizó una entrevista en la cual se recogió, mediante cuestionario, información de las tres variables de muestreo: sociodemográficas, ocupacionales, clínicas y toxicológicas. Se determinaron los niveles de 13 organoclorados en suero mediante cromatografía de gases en el Instituto Nacional de Salud. Se llevó a cabo un análisis descriptivo y se llevo a cabo un análisis para determinar la distribución de medias entre variables de exposición ocupacional (Ji2 para cualitativas y U de Mann-Whitney para cuantitativas). Posteriormente, se llevó a cabo un análisis multivariado para estimar la asociación controlando por variables de antigüedad, exposición laboral a organoclorados. Resultados: El reporte de manipulación de insecticidas organoclorados fue del 39,1%. El 100% de los trabajadores que usaron organoclorados refirieron el uso DDT. El 7,5% (n=3) refirieron el uso de Aldrin. Los organoclorados fueron hexaclorbenceno, hexaclorocicloexano, heptacloro, heptaclorepoxi, α-Clordano, 4,4-DDT, 4,4-DDE, β -endosulfan, 2,4- DDT, endosulfan sulfato y mirex. Los organoclorados con niveles pico más altos fueron β-HCH, 4,4- DDT y α –HCH. Los síntomas de mayor presentación fueron: cefalea 28,7%, mareo 29,9%, disminución de fuerza en MMSS 17,2% y síntomas neurosiquiátricos.

Insect and bird interactions

This unique book is the first of its kind to explore the diversity of interactions between insects and birds. A group of international experts enthusiastically agreed to contribute to the four sections of the book following the success of an Entomological Club Conference on Insect and Bird Interactions. The first section covers population management issues, discussing effects on birds highly relevant to the planting of large areas of GM crops, new opportunities for increasing biodiversity in farming landscapes, and the novel aspect of managing insects by exploiting birds as biological control agents. This is followed by a section discussing the effects of insecticides on bird populations, and includes a contribution from the RSPB, as well as a re-appraisal of the effects of DDT on raptors. Next, the foraging behaviour of birds on insects is discussed, with chapters also on 'warning' coloration in insects and learning by birds. The first chapter in this section is unusual in having been written by an ophthalmologist and covers colour vision in birds, more specifically ultraviolet vision in relation to insect coloration. Finally, the authors look at insects that are parasites of birds or feed on the detritus in nests, and review the ecology and evolution of the co-adaptation of insect ectoparasites with birds. Insect and Bird Interactions is unparalleled in scope and coverage and will be of interest to entomologists, ornithologists, and ecologists alike.

Effect of morphine on the growth rate of Calliphora stygia (Fabricius) (Diptera : Calliphoridae) and possible implications for forensic entomology

Insect specimens collected from decomposing bodies enable forensic entomologists to estimate the minimum post-morten interval (PMI). Drugs and toxins within a corpose may affect the development rate of insects that feed on them and it is vital to quantify these effects to accurately calculate minimum PMI.... This suggests that C. sygia is a reliable model to use to accurately age a corpse containing morphine at any of the concentrations investigated.

Quaternary beetles : a review and issues for Australian studies

Few Australian entomologists, ecologists, biogeographers or Quaternary researchers are familiar with the details of Quaternary beetle research. Since the 1950s the study of fossil beetles has developed to become an important discipline of the Quaternary sciences. Unfortunately, however, the significance of the discipline for ecological and evolutionary research has been slow to penetrate mainstream entomological, ecological, and evolutionary thought. This paper outlines the history, methods and results of Quaternary beetle studies, based primarily upon research from the well-studied Northern Hemisphere, and then examines issues relevant to Australian research. Analysis of Quaternary beetle assemblages from Australia can contribute to the reconstruction of past environments and climates, in particular quantitative estimation of past temperature regimes, and potentially, effective precipitation. Of more significance to entomology, however, is the potential to reconstruct climatically-induced changes in distribution, essential for understanding the Quaternary biogeographic history of Australia's insect fauna. Furthermore, it will be possible to examine evidence, or the lack thereof, for speciation during the Quaternary, in the context of Quaternary environmental change.

Letters to a young scientist by Edward O. Wilson : interview

I am an early- to mid-career researcher, and Letters to a Young Scientist struck a chord with me from the very first page. The journey from amateur enthusiast to professional scientist is an exciting, challenging and often difficult one, and Edward Wilson - a Pulitzer prizewinner and one of the world's greatest entomologists - is well qualified to guide and advise the new generation. Written as a collection of letters filled with anecdotes and well-considered advice, this book is inspired by the author's experience of the journey from being a young boy enthused by ants to an eminent scholar. Like many in his field, Wilson's education began when he was a child fascinated by insects in the garden (my own summers spent excavating ant nests feel somewhat validated). He traces his progression through formal education to the establishment of his own scientific research programme.
