Study Guide Entomology & Nematology Department
STUDY GUIDE ENTOMOLOGY & NEMATOLOGY DEPARTMENT DPM COMPREHENSIVE EXAMINATIONS The Entomology & Nematology Comprehensive Examinations consist of 3 sections: pest identification (30%), pest biology and management (40%), and core concepts and synthesis (30%). These examinations are limited to information about invertebrate animal pests, principally insects and nematodes, but also plant feeding mites and terrestrial molluscs. A. Pest identification Students will be presented with insects, mites, molluscs, and nematodes that they must identify. Some may be recognizable by sight, but others may require keys for identification. Students will be provided with identification aids (keys), where necessary, and be expected to use them to identify the subjects accurately. The unknowns will be selected from the list of important insect, mite, mollusc, and nematode pests (Table 1) though we will emphasize those with a single or double asterisk [* or **]), as these normally are the more important pests. Included in this list are some that pose a threat but are not currently found in Florida. B. Pest biology and management Students will answer 8-10 questions on insect, mite, mollusc, and nematode pest biology (sampling, distribution, life cycle, damage) and management. The animals for which students are responsible to know biology and management are listed in Table 1 (preceded by double asterisk [**]). C. Core Concepts and Synthesis Section: Students will answer 3 or 4 questions that cover core areas of Entomology/Nematology and demonstrate knowledge of core areas, but also analysis and problem solving. Suggested reference/reading material is listed in Table 2. You might want to read through these in preparation for the Comprehensive Examinations. -
(Mollusca, Gastropoda) of the Bulgarian Part of the Alibotush Mts
Malacologica Bohemoslovaca (2008), 7: 17–20 ISSN 1336-6939 Terrestrial gastropods (Mollusca, Gastropoda) of the Bulgarian part of the Alibotush Mts. IVAILO KANEV DEDOV Central Laboratory of General Ecology, 2 Gagarin Str., BG-1113 Sofia, Bulgaria, e-mail: [email protected] DEDOV I.K., 2008: Terrestrial gastropods (Mollusca, Gastropoda) of the Bulgarian part of the Alibotush Mts. – Malacologica Bohemoslovaca, 7: 17–20. Online serial at <http://mollusca.sav.sk> 20-Feb-2008. This work presents results of two years collecting efforts within the project “The role of the alpine karst area in Bulgaria as reservoir of species diversity”. It summarizes distribution data of 44 terrestrial gastropods from the Bulgarian part of Alibotush Mts. Twenty-seven species are newly recorded from the Alibotush Mts., 13 were con- firmed, while 4 species, previously known from the literature, were not found. In the gastropod fauna of Alibotush Mts. predominate species from Mediterranean zoogeographic complex. A large part of them is endemic species, and this demonstrates the high conservation value of large limestone areas in respect of terrestrial gastropods.

A short survey on the parasite fauna of terrestrial molluscs in south-east of Sicily was performed. In total, 432 specimens of 12 different snail species from the families Cochlostomatidae, Clausiliidae, Subulinidae, and Helicidae and five slug species from the families Agriolimacidae, Limacidae and Milacidae were collected and examined. Seven out of 17 examined gastropod species in the area were susceptible to nematode infection. Representatives of three nematode taxa, Angiostoma margaretae Ross, Malan & Ivanova, 2011, Phasmarhabditis spp. and Caenorhabditis elegans (Maupas, 1900), were isolated and molecularly characterised. New host, Papillifera papillaris affinis (Philippi, 1836), was recorded for A. margaretae, originally described from South Africa. The discovery of two different strains or even putative species of Phasmarhabditis at close localities is indicative of its possible diversity in the area. Trematodes from four families were found at four sites in Rumina decollata (Linnaeus, 1758), Cornu aspersum (O.F. Müller, 1774), Ambigolimax valentianus (Férussac, 1822), Tandonia sowerbyi (A. Férussac, 1823) and Milax nigricans (Philippi, 1836). Mixed trematode/nematode infection was observed in R. -

Within Ariantinae, C. obtusus stands out because of its aberrant cylindrical shell shape. Here, we present phylogenetic trees based on these five marker sequences and discuss the position of C. obtusus and phylogeographical scenarios in comparison with previously published results. Our results provide strong support for the sister-group relationship between Cylindrus and Arianta confirming previous studies and imply that the split between the two genera is quite old. The tree reveals a phylogeographical pattern of Ariantinae with a well-supported clade comprising the Balkan taxa which is the sister group to a clade with individuals from Alpine localities. -
New Anatomical Data on the Iberian Endemic Atenia Quadrasi (Hidalgo, 1885) (Pulmonata, Helicodontidae)
JOURNAL OF CONCHOLOGY (2006), VOL.39, NO.1 55 NEW ANATOMICAL DATA ON THE IBERIAN ENDEMIC ATENIA QUADRASI (HIDALGO, 1885) (PULMONATA, HELICODONTIDAE) ALBERTO MARTÍNEZ-ORTÍ1 1 Museu Valencià d’Història Natural. Passeig de la Petxina, 15. E-46008 Valencia (Spain) Abstract Living Atenia quadrasi (Hidalgo, 1855) were collected from Pego (Alicante) giving new data about the repro- ductive system, shell, radula and jaw. This data suggests that the genus Atenia Gittenberger, 1968 should be placed in the Subfamily Lindholmiolinae Schileyko, 1978 within the Family Helicodontidae Kobelt, 1904. The small range of this species and the threat to the habitat both suggest that A. quadrasi should be considered threatened.

Mollusca – Mollusks Glistening trails of pearly mucous criss-cross mats and also seemed to be a preferred food. Perhaps we need to turfs of green, signalling the passing of snails and slugs on searach at night when the snails and slugs are more active. the low-growing bryophytes (Figure 1). In California, the white desert snail Eremarionta immaculata is more common on lichens and mosses than on other plant detritus and rocks (Wiesenborn 2003). Wiesenborn suggested that the snails might find more food and moisture there. Are these mollusks simply travelling from one place to another across the moist moss surface, or do they have a more dastardly purpose for traversing these miniature forests? Quantitative information on snails and slugs among bryophytes is scarce, and often only mentions that bryophytes are abundant in the habitat (e.g. Nekola 2002), but we might be able to glean some information from a study by Grime and Blythe (1969). In collections totalling 82.4 g of moss, they examined snail populations in a 0.75 m2 plot each morning on 7, 8, 9, & 12 September 1966. The copse snail, Arianta arbustorum (Figure 2), numbered 0, 7, 2, and 6 on those days, respectively, with weights of Figure 2.

Development and R Elopment and R Elopment and Reproduction In
Development and reproduction in Bulimulus tenuissimus (Mollusca: Bulimulidae) in laboratory Lidiane C. Silva; Liliane M. O. Meireles; Flávia O. Junqueira & Elisabeth C. A. Bessa Núcleo de Malacologia, Departamento de Zoologia, Instituto de Ciências Biológicas, Universidade Federal de Juiz de Fora. Campus Universitário, 36036-330 Juiz de Fora, Minas Gerais, Brasil. E-mail: [email protected] ABSTRACT: Bulimulus tenuissimus (d’Orbigny, 1835) is a land snail of parasitological importance with a poorly understood biology. The goal of this laboratory study was to determine development and reproductive patterns in B. tenuissimus. Recently hatched individuals in seven groups of 10 were maintained in the laboratory for two years. To test for self-fertilization, 73 additional individuals were isolated. After 180 days the isolated snails showed no signs of reproduction. Subsequently, 30 of these snails were paired to test fertility. We noted the date and time of egg-laying, the number of eggs produced, the number of egg-layings per individual, the incubation period and hatch success. This species shows indeterminate growth. Individuals that were maintained with others, as compared to isolated individuals, laid eggs sooner, laid more eggs and had a greater hatching success. This species can self-fertilize, however, with lower reproductive success. Bulimulus tenuissimus has a well-defined repro- ductive period that is apparently characteristic for this species. KEY WORDS. Growth; land snail; reproduction. RESUMO. Padrão de desenvolvimento e aspectos reprodutivos de Bulimulus tenuissimus (Mollusca: Bulimulidae) em condições de laboratório.

Land Snails of Leicestershire and Rutland
Land Snails of Leicestershire and Rutland Introduction There are 50 known species of land snail found in Leicestershire and Rutland (VC55) which represents about half of the 100 UK species. However molluscs are an under-recorded taxon group so it is possible that more species could be found and equally possible that a few may now be extinct in our two counties. There was a 20 year period of enthusiastic mollusc recording between 1967 and 1986, principally by museum staff, which account for the majority of species. Whilst records have increased again in the last three years thanks to NatureSpot, some species have not been recorded for over 30 years. All our land snails are in the class Gastropoda and the order Pulmonata. Whilst some of these species require damp habitats and are generally found near to aquatic habitats, they are all able to survive out of water. A number of species are largely restricted to calcareous habitats so are only found at a few sites. The sizes stated refer to the largest dimension of the shell typically found in adult specimens. There is much variation in many species and juveniles will of course be smaller. Note that the images are all greater than life size and not all the to the same scale. I have tried to display them at a sufficiently large scale so that the key features are visible. Always refer to the sizes given in the text. Status refers to abundance in Leicestershire and Rutland (VC55). However molluscs are generally under- recorded so our understanding of their distribution could easily change.
