Bunn Road, Prosser, WA 99350, U.S.A Foottit R.G., Maw H.E.L., Pike K.S. – DNA barcodes to explore diversity in aphids (Hemiptera Aphididae and Adelgidae). A tendency towards loss of taxonomically useful characters, and morphological plasticity due to host and environmental factors, complicates the identification of aphid species and the analysis of relationships. The presence of different morphological forms of a single species on different hosts and at different times of the year makes it difficult to consistently associate routinely collected field samples with particular species definitions. DNA barcoding has been proposed as a standardized approach to the characterization of life forms. We have tested the effectiveness of the standard 658-bp barcode fragment from the 5’ end of the mitochondrial cytochrome c oxidase 1 gene (COI) to differentiate among species of aphids and adelgids. Results are presented for a preliminary study on the application of DNA barcoding in which approximately 3600 specimens representing 568 species and 169 genera of the major subfamilies of aphids and the adelgids have been sequenced. Examples are provided where DNA barcoding has been used as a tool in recognizing the existence of cryptic new taxa, linking life stages on different hosts of adelgids, and as an aid in the delineation of species boundaries. -

Although these medically important Rickettsia are often transmitted via haematophagous arthropods, other Rickettsia, such as those in the Torix group, appear to reside exclusively in invertebrates and protists with no secondary vertebrate host. Importantly, little is known about the diversity or host range of Torix group Rickettsia. -

DISTRIBUTION of VILLAS and SOME of the MAL TESE ECONOMY in the ROMAN PERIOD by ANTIIONY BONANNO
DISTRIBUTION OF VILLAS AND SOME OF THE MAL TESE ECONOMY IN THE ROMAN PERIOD by ANTIIONY BONANNO CERTAINLY one of the most striking aspects of the Maltese archae ology of the Roman period is the comparatively large number of villas, or rural houses, distributed in different areas of the two major islands of the Maltese archipelago. Already twenty-two sites have been recorded, their state of preservation ranging from just a few foundation wall s to full-seal e buil din g compl exe s. By far the largest and most impressive remains of such buildings are those excavated in recent years by the Italian Mission from the University of Rome at San Pawl Milqi.l Another villa, not much smaller in scale, was excavated in 1915 by Ashby at Ta' Kacca tura, near Biri:ebbuga, on the other side of the valley opposite the well-known prehistoric site of Gnar Dalam. 2 Yet another is cur rently being excavated by the Mus~um Department at Zejtun. 3 The thermal complex of Gnajn Tuffiena, decorated with pleasant and varied geometrical mosaics, must have formed part of a sumptuous villa. 4 Traces of similar baths have been recorded at Marsaxlokk,5 and another villa with richly patterned mosaics was brought to light at Ramla Bay in Gozo. 6 Other sites which have produced re mains of villas are: Tas-Sittin (near Fawwara), Ras ir-Raheb (near Bahrija), Fiddien (near ,Mtahleb), Wardija, Bidnija, Hal Far and St. Thomas Bay.7, Until its name is corrected it may not be super fluous to repeat that the so-called 'Roman Villa' of Rabat is not a villa at all, but a Roman town house. -

Colonization of Ecological Islands: Galling Aphid Populations (Sternorrhyncha: Aphidoidea: Pemphigidae) on Recoveringpistacia Trees After Destruction by Fire
Eur. J. Entomol. 95: 41-53, 1998 ISSN 1210-5759 Colonization of ecological islands: Galling aphid populations (Sternorrhyncha: Aphidoidea: Pemphigidae) on recoveringPistacia trees after destruction by fire D avid WOOL and M oshe INBAR* Department of Zoology, George S. Wise Faculty of Life Sciences, Tel Aviv University, 69978 Israel; e-mail: [email protected] Gall-forming aphids, Pemphigidae, Fordinae,Pistacia, fire, recolonization Abstract. Pistacia palaestina (Anacardiaceae) is a common tree in the natural forest of Mt. Carmel, Is rael, and the primary host of five common species of gall-forming aphids (Sternorrhyncha: Aphidoidea: Pemphigidae: Fordinae). After a forest fire, resprouting P. palaestina trees, which are colonized by migrants from outside the burned area, become “ecological islands” for host-specific herbivores. A portion of the Carmel National Park was destroyed by fire in September of 1989. The same winter, thirty-nine resprouting trees that formed green islands in the otherwise barren environment were identified and marked. Tree growth was extraordinarily vigorous during the first year after the fire, but shoot elon gation declined markedly in subsequent years. Recolonization of the 39 “islands” by the Fordinae was studied for six consecutive years. Although the life cycle of the aphids and the deciduous phenology of the tree dictate that the “islands” must be newly recolonized every year, the results of this study show that trees are persistently occupied once colonized. This is probably due to establishment of aphid colonies on the roots of secondary hosts near each tree following the first successful production of a gall. Differences in colonization success of different species could be related to both the abundance of dif ferent aphid species in the unburned forest and the biological characteristics of each aphid species. -

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). -

A new species of the genus Tramaforda Manheim, 2007 (Hemiptera, Aphididae, Eriosomatinae, Fordini). Spixiana 43 (1): 93-104. Tramaforda wooli Manheim belongs to a monotypic genus that induces galls on Pistacia atlantica Desf. in Israel. Based on distinct gall characteristics, differences in morphometrics and molecular markers (CO I, CO II and microsatellite analysis), we recognized a new species in this genus, Tramaforda koachi sp. nov. which is cur- rently endemic to north-central Israel and the Golan Heights. Fall migrants of Tramaforda koachi sp. nov. are smaller (1.62-2.02 mm) than the same form of T. wooli (> 2.14 mm). However, no distinct qualitative morphological differences were found between fall migrants of these two species.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).
