  • Some Aspects of the Ecology of Millipedes (Diplopoda) Thesis
    Some Aspects of the Ecology of Millipedes (Diplopoda) Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Monica A. Farfan, B.S. Graduate Program in Evolution, Ecology, and Organismal Biology The Ohio State University 2010 Thesis Committee: Hans Klompen, Advisor John W. Wenzel Andrew Michel Copyright by Monica A. Farfan 2010 Abstract The focus of this thesis is the ecology of invasive millipedes (Diplopoda) in the family Julidae. This particular group of millipedes are thought to be introduced into North America from Europe and are now widely found in many urban, anthropogenic habitats in the U.S. Why are these animals such effective colonizers and why do they seem to be mostly present in anthropogenic habitats? In a review of the literature addressing the role of millipedes in nutrient cycling, the interactions of millipedes and communities of fungi and bacteria are discussed. The presence of millipedes stimulates fungal growth while fungal hyphae and bacteria positively effect feeding intensity and nutrient assimilation efficiency in millipedes. Millipedes may also utilize enzymes from these organisms. In a continuation of the study of the ecology of the family Julidae, a comparative study was completed on mites associated with millipedes in the family Julidae in eastern North America and the United Kingdom. The goals of this study were: 1. To establish what mites are present on these millipedes in North America 2. To see if this fauna is the same as in Europe 3. To examine host association patterns looking specifically for host or habitat specificity.

  • Ommatoiulus Moreleti (Lucas) and Cylindroiulus
    Bulletin of the British Myriapod & Isopod Group Volume 30 (2018) OMMATOIULUS MORELETI (LUCAS) AND CYLINDROIULUS PYRENAICUS (BRÖLEMANN) NEW TO THE UK (DIPLOPODA, JULIDA: JULIDAE) AND A NEW HOST FOR RICKIA LABOULBENIOIDES (LABOULBENIALES) Steve J. Gregory1, Christian Owen2, Greg Jones and Emma Williams 1 4 Mount Pleasant Cottages, Church Street, East Hendred, Oxfordshire, OX12 8LA, UK. E-mail: [email protected] 2 75 Lewis Street, Aberbargoed. CF8 19DZ, UK. E-mail: [email protected] ABSTRACT The schizophylline millipede Ommatoiulus moreleti (Lucas) and the cylindroiuline millipede Cylindroiulus pyrenaicus (Brölemann) (Julida: Julidae) are recorded new for the UK from a site near Bridgend, Glamorganshire, in April 2017. An unidentified millipede first collected in April 2004 from Kenfig Burrows, Glamorganshire, is also confirmed as being C. pyrenaicus. Both species are described and illustrated, enabling identification. C. pyrenaicus is reported as a new host for the Laboulbeniales fungus Rickia laboulbenioides. Summary information is provided on habitat preferences of both species in South Wales and on their foreign distribution and habitats. It is considered likely that both species have been unintentionally introduced into the UK as a consequence of industrial activity in the Valleys of south Wales. INTRODUCTION The genera Ommatoiulus Latzel, 1884 and Cylindroiulus Verhoeff, 1894 (Julida: Julidae) both display high species diversity (Kime & Enghoff, 2017). Of the 47 described species of Ommatoiulus the majority are found in North Africa and the Iberian Peninsula (ibid). Currently, just one species, Ommatoiulus sabulosus (Linnaeus, 1758), is known from Britain and Ireland, a species that occurs widely across northern Europe (Kime, 1999) and in Britain reaches the northern Scottish coastline (Lee, 2006).

  • Portuguese Millipedes Portuguese Millipedes (Ommatoiulus Moreleti (Diplodia, Julida: Julidae) Invade Houses in a Number of City and Country Areas in SA
    Thursday, 15 September, 2016 Author: Peter Bailey, Contact: Greg Baker Portuguese Millipedes Portuguese millipedes (Ommatoiulus moreleti (Diplodia, Julida: Julidae) invade houses in a number of city and country areas in SA. These millipedes are now part of the environment. This fact sheet describes something of their life history, how the householder can minimise the impact of invasions, and how the Department of Primary Industries and Regions SA efforts at biological control may eventually reduce numbers below nuisance level. DESCRIPTION The Portuguese millipede belongs to a group of animals which have many body segments and two pairs of legs on most body segments. Millipedes are vegetarians, eating soft vegetation such as decaying leaf litter, mosses and pollen. Many species of millipedes occur in temperate and tropical parts of the world; Australia has numerous native species, some of which occur in SA. BENEFITS Millipedes are probably important in soil formation. They break down leaf litter and enrich the soil. MILLIPEDES AS PESTS Portuguese millipedes are pests because they invade houses. They are one of the few millipede species that are attracted to lights at night, and this behaviour explains why they invade houses. Once inside a house they usually die. They do not breed inside houses. Millipede invasions vary in intensity, depending on the environment surrounding a house. Where millipedes are dense, invasions of hundreds, or even thousands, may occur during several days. MILLIPEDES AND HEALTH There is no evidence that Portuguese millipedes affect human health. Their bodies contain rows of glands that secrete a pungent yellowish secretion when the millipede is agitated.

  • The Black Portuguese Millipede, Ommatoiulus Moreleti, Is a Native of Portugal and Was Accidentally Introduced to Australia, First Appearing in South Australia in 1953
    The black Portuguese millipede, Ommatoiulus moreleti, is a native of Portugal and was accidentally introduced to Australia, first appearing in South Australia in 1953. They have since invaded all the southern mainland states. They are attracted to light and will enter buildings at night, although once inside they do not breed and will eventually die. While there is no evidence they affect human health, they can occur in plague numbers, and can contaminate food and infest carpet and bedding. Portuguese millipedes are herbivorous, which means in plague proportions they may also destroy seedlings and fruit and vegetable crops. When disturbed a millipede may release a pungent and distasteful yellowish secretion which discourages predators, such as birds. Note: the secretion may stain skin or clothes and is extremely irritating if rubbed into the eyes. However as it is composed of organic chemicals called quinones, it quickly breaks down in water. Mature black Portuguese millipedes are smooth and cylindrical, 20-45 mm long and slate- grey to black in colour. Juveniles are light brown and striped. Juveniles hatch from eggs in the soil and reach maturity in two years. During hot dry weather they will hide in the soil, however rain in spring and particularly in autumn will stimulate activity and breeding. What to do? Lighting Portuguese millipedes are attracted to light. If you are able to do so, turn off any external lights which are close to your house or other buildings and minimise any escape of light by closing curtains and blinds. Use weather-strips on doors as good door seals will also help prevent entry into the home.

ZooKeys 703: 97–107. https://doi.org/10.3897/zookeys.703.20986 Abstract Tridactylogonus warrenbenensis sp. n. is described from Warrenben Conservation Park at the southern end of the Yorke Peninsula in South Australia. Like T. obscurus Jeekel, 1982 and T. rugosissimus Jeekel, 2002, the new species has prominent cellular sculpturing on the prozonites and granulose sculpturing on parts of the metazonites. Unlike its congeners and most species in the subfamily Australiosomatinae, the new species lacks a femoral process or tubercle on male leg 1. Keywords Diplopoda, Polydesmida, Paradoxosomatidae,South Australia, Australia Introduction I collected the new species described here during two recent visits to the lower Yorke Peninsula in South Australia (Fig. 1). It was the only native polydesmidan species I found in the area, much of which has been heavily colonised by the introduced Portug- ese millipede Ommatoiulus moreleti (Lucas, 1860). It is a remarkably atypical species within the Australian Paradoxosomatidae, as it lacks a femoral process on male leg 1 and has prominent cuticular sculpturing on the prozonites and metazonites.

ABSTRACT This paper deals with the conceptions, knowledge and attitudes of the inhabitants of the county of Pedra Branca, Bahia State, on the arthropods of the class Diplopoda. Data were collected from February to June 2005 by means of open-ended interviews carried out with 28 individuals, which ages ranged from 13 to 86 years old. It was recorded some traditional knowledge regarding the following items: taxonomy, biology, habitat, ecology, seasonality, and behavior. Results show that the diplopods are classified as “insects”. The characteristic of coiling the body was the most com- mented, as well as the fact that these animals are considered as “poisonous”. In gen- eral, the traditional zoological knowledge of Pedra Branca’s inhabitants concerning the diplopods is coherent with the academic knowledge. Key words: Ethnozoology, ethnomyriapodology, perception, millipede. RESUMEN Este artículo registra las concepciones, los conocimientos y los comportamientos que los habitantes del poblado de Pedra Branca, en el estado de Bahía, poseen sobre los artrópodos de la clase Diplopoda.
