Sandidge 1 Abstract The Community Ecology of Ants (Formicidae) in Indonesian Grasslands with Special Focus on the Tropical Fire Ant, Solenopsis geminata. by Rebecca L. Sandidge Doctor of Philosophy in Environmental Science Policy and Management, Berkeley Professor Neil Tsutsui, Chair Invasive species and habitat destruction are considered to be the leading causes of biodiversity decline, signaling declining ecosystem health on a global scale. Ants (Formicidae) include some on the most widespread and impactful invasive species capable of establishing in high numbers in new habitats. The tropical grasslands of Indonesia are home to several invasive species of ants. Invasive ants are transported in shipped goods, causing many species to be of global concern. My dissertation explores ant communities in the grasslands of southeastern Indonesia. Communities are described for the first time with a special focus on the Tropical Fire Ant, Solenopsis geminata, which consumes grass seeds and can have negative ecological impacts in invaded areas. The first chapter describes grassland ant communities in both disturbed and undisturbed grasslands. -

Müller, 1818 and Claviger testaceus Preyssler, 1790. Both species are rare in Poland. Beetles of the genus Claviger are specialized myrmecophiles and are dependent on their host ants throughout the whole life cycle. During the field research, which were conducted in the Low Beskid Mts. (South-Eastern Poland), new sites of both species were found. C. longicornis was recorded in a colony of Lasius sabularum (Bondroit, 1918) and this is the first record of this ant as its host . -

These introduced species are called as non-native, exotic, invasive or tramp species. Here we record the well-known tramp species Tetramorium lanuginosum Mayr, for the first time from Turkey (Antalya-Alanya), and present first locality records for Paratrechina longicornis (Latreille) from Antalya- Alanya and Adana. Thus, the number of tramp ant species of Turkey is increased to 19. Key words: Tramp species, new record, Northeastern Mediterranean, Antalya-Alanya. Özet: Turizm, gelişmiş ulaşım ve artan ticaret gibi insan faaliyetleri faunal elemanların dağılım alanları dışındaki habitatlara taşınmasına neden olmakta ve dolayısıyla yerli faunayı etkilemektedir. Bu faaliyetlerle taşınan organizmalar yerli olmayan, egzotik, istilacı veya tramp türler olarak adlandırılır. Bu çalışmada, çok iyi bilinen tramp karınca türü olan Tetramorium lanuginosum Mayr’u Türkiye’den (Antalya-Alanya) ilk defa kayıt edilmekte ve Paratrechina longicornis (Latreille)’e ait ilk lokalite kayıtları ise Antalya-Alanya ve Adana’dan verilmektedir. -

Notes on Ants (Hymenoptera: Formicidae) from Gambia (Western Africa)
ANNALS OF THE UPPER SILESIAN MUSEUM IN BYTOM ENTOMOLOGY Vol. 26 (online 010): 1–13 ISSN 0867-1966, eISSN 2544-039X (online) Bytom, 08.05.2018 LECH BOROWIEC1, SEBASTIAN SALATA2 Notes on ants (Hymenoptera: Formicidae) from Gambia (Western Africa) http://doi.org/10.5281/zenodo.1243767 1 Department of Biodiversity and Evolutionary Taxonomy, University of Wrocław, Przybyszewskiego 65, 51-148 Wrocław, Poland e-mail: [email protected], [email protected] Abstract: A list of 35 ant species or morphospecies collected in Gambia is presented, 9 of them are recorded for the first time from the country:Camponotus cf. vividus, Crematogaster cf. aegyptiaca, Dorylus nigricans burmeisteri SHUCKARD, 1840, Lepisiota canescens (EMERY, 1897), Monomorium cf. opacum, Monomorium cf. salomonis, Nylanderia jaegerskioeldi (MAYR, 1904), Technomyrmex pallipes (SMITH, 1876), and Trichomyrmex abyssinicus (FOREL, 1894). A checklist of 82 ant species recorded from Gambia is given. Key words: ants, faunistics, Gambia, new country records. INTRODUCTION Ants fauna of Gambia (West Africa) is poorly known. Literature data, AntWeb and other Internet resources recorded only 59 species from this country. For comparison from Senegal, which surrounds three sides of Gambia, 89 species have been recorded so far. Both of these records seem poor when compared with 654 species known from the whole western Africa (SHUCKARD 1840, ANDRÉ 1889, EMERY 1892, MENOZZI 1926, SANTSCHI 1939, LUSH 2007, ANTWIKI 2017, ANTWEB 2017, DIAMÉ et al. 2017, TAYLOR 2018). Most records from Gambia come from general web checklists of species. Unfortunately, they lack locality data, date of sampling, collector name, coordinates of the locality and notes on habitats. -
Evaluation of the Chemical Defense Fluids of Macrotermes Carbonarius
www.nature.com/scientificreports OPEN Evaluation of the chemical defense fuids of Macrotermes carbonarius and Globitermes sulphureus as possible household repellents and insecticides S. Appalasamy1,2*, M. H. Alia Diyana2, N. Arumugam2 & J. G. Boon3 The use of chemical insecticides has had many adverse efects. This study reports a novel perspective on the application of insect-based compounds to repel and eradicate other insects in a controlled environment. In this work, defense fuid was shown to be a repellent and insecticide against termites and cockroaches and was analyzed using gas chromatography-mass spectrometry (GC– MS). Globitermes sulphureus extract at 20 mg/ml showed the highest repellency for seven days against Macrotermes gilvus and for thirty days against Periplaneta americana. In terms of toxicity, G. sulphureus extract had a low LC50 compared to M. carbonarius extract against M. gilvus. Gas chromatography–mass spectrometry analysis of the M. carbonarius extract indicated the presence of six insecticidal and two repellent compounds in the extract, whereas the G. sulphureus extract contained fve insecticidal and three repellent compounds. The most obvious fnding was that G. sulphureus defense fuid had higher potential as a natural repellent and termiticide than the M. carbonarius extract. Both defense fuids can play a role as alternatives in the search for new, sustainable, natural repellents and termiticides. Our results demonstrate the potential use of termite defense fuid for pest management, providing repellent and insecticidal activities comparable to those of other green repellent and termiticidal commercial products. A termite infestation could be silent, but termites are known as destructive urban pests that cause structural damage by infesting wooden and timber structures, leading to economic loss. -
Ants (Hymenoptera: Formicidae) of Bermuda
212 Florida Entomologist 87(2) June 2004 ANTS (HYMENOPTERA: FORMICIDAE) OF BERMUDA JAMES K. WETTERER1 AND ANDREA L. WETTERER2 1Wilkes Honors College, Florida Atlantic University, 5353 Parkside Drive, Jupiter, FL 33458 2Department of Ecology, Evolution, and Environmental Biology, Columbia University, New York, NY 10027 ABSTRACT For more than 50 years, two exotic ant species, Linepithema humile (Mayr) and Pheidole megacephala (F.), have been battling for ecological supremacy in Bermuda. Here we summa- rize known ant records from Bermuda, provide an update on the conflict between the domi- nant ant species, and evaluate the possible impact of the dominant species on the other ants in Bermuda. We examined ant specimens from Bermuda representing 20 species: Brachy- myrmex heeri Forel, B. obscurior Forel, Camponotus pennsylvanicus (De Geer), Cardio- condyla emeryi Forel, C. obscurior Wheeler, Crematogaster sp., Hypoponera opaciceps (Mayr), H. punctatissima (Roger), L. humile, Monomorium monomorium Bolton, Odontomachus rug- inodis Smith, Paratrechina longicornis (Latreille), P. vividula (Nylander), P. megacephala, Plagiolepis alluaudi Forel, Solenopsis (Diplorhoptrum) sp., Tetramorium caldarium Roger, T. simillimum (Smith), Wasmannia auropunctata (Roger), and an undetermined Dacetini. Records for all but three (H. punctatissima, P. vividula, W. auropunctata) include specimens from 1987 or later. We found no specimens to confirm records of several other ant species, in- cluding Monomorium pharaonis (L.) and Tetramorium caespitum (L.). Currently, L. humile dominates most of Bermuda, while P. megacephala appear to be at its lowest population lev- els recorded. Though inconspicuous, B. obscurior is common and coexists with both dominant species. Paratrechina longicornis has conspicuous populations in two urban areas. Three other ant species are well established, but inconspicuous due to small size (B. -

Roberto José Guerrero Flórez, para optar al título de Doctor en Ciencias Tutor (es): Juan Carlos Navarro, Ph. D. Fernando Fernández, Ph. D (ICN-UN, Colombia) Caracas – Venezuela Octubre de 2017 2 3 RESUMEN Las hormigas del género Tapinoma son un elemento conspicuo adentro de la subfamilia Dolichoderinae. Estas hormigas son cosmopolitas, exhibiendo una mayor riqueza de especies en las regiones paleotropicales, no obstante, la región Neotropical alberga una fauna considerable de especies de Tapinoma. Por primera vez y tomando en consideración las especies de la región Neotropical, se revisan taxonómicamente las especies del género Tapinoma. El análisis morfológico, datos de distribución y en algunos casos la integración de información ecológica, respaldan la delimitación de 10 especies distribuidas en cuatro grupos de especies (Grupo Litorale, Grupo Melanocephalum, Grupo Ramulorum y Grupo Sessile), de los cuales Litorale y Ramulorum albergan el mayor número de especies Neotropicales. El esquema taxonómico es el siguiente: Tapinoma amazonae Wheeler, W.M. 1934, Tapinoma atriceps Emery, 1888 (=Tapinoma atriceps breviscapus Forel, 1908), Tapinoma inrectum Forel, 1908 (estatus revisado y revivido), T. litorae Wheeler, 1905 (=litorale cubaensis Wheeler, W.M. 1913, nuevo sinónimo; =panamense Wheeler, W.M. 1934, nuevo sinónimo), T. melanocephalum (Fabricius, 1793) (=T. luffae (Kuriam 1955), nuevo sinónimo; =T. melanocephalum coronatum Forel, 1908, nuevo sinónimo; =T. melanocephalum malesianum Forel, 1913, nuevo sinónimo), T. opacum Wheeler, W.M. & Mann, 1914, T. -
