A reVlSIOn of the genus Eriosoma and its allied genera in Japan (Homoptera: Aphidoidea). Ins. matsum. n.S. 27: 37-106, 3 tabs., 26 figs. Nine species of Eriosoma and its allied genera, all leaf-roll aphids on Ulmaceae and occur ring in Japan, are dealt with. Descriptions of gall-generations, exules, sexuparae and galls are given, with brief biological notes for some species. The species-complex hitherto called Eriosoma japonicum is classified into 6 species, including 5 ones new to science. A parasitic form of Eriosoma yangi, occurring on Ulmus davidiana var. japonica, is formally described as a new subspecies different from the nominate form on Ulmus parvifolia in not only behavior but also morphological characters of their fundatrices. The subdivision of Eriosoma is recon sidered in connection with the divergence and distribution of the host plants, and the ulmi group is newly proposed. A leaf-roll aphid associated with Zelkova is described as a new species belonging to Hemipodaphis, which has only been known from the morph occurring on the secon dary host in India; on the basis of the new species Hemipodaphis is transferred to the Pemphigidae (Eriosomatinae) from the Hormaphididae. -

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. -

Conservation Biological Control of Rosy Apple Aphid, Dysaphis Plantaginea (Passerini), in Eastern North America
COMMUNITY AND ECOSYSTEM ECOLOGY Conservation Biological Control of Rosy Apple Aphid, Dysaphis plantaginea (Passerini), in Eastern North America 1 2 M. W. BROWN AND CLARISSA R. MATHEWS Environ. Entomol. 36(5): 1131Ð1139 (2007) ABSTRACT Because of the potentially serious damage rosy apple aphid, Dysaphis plantaginea (Passerini) (Homoptera: Aphididae), can cause to apple fruit and branch development, prophylactic insecticides are often used for control. If biological control could be relied on, the amount of pesticide applied in orchards could be reduced. This study examined biological control of rosy apple aphid in eastern West Virginia and the potential for enhancement through conservation biological control, in particular, the effect of interplanting extraßoral nectar-bearing peach trees. By 20 d after Þrst bloom, only 2% of fundatrices initially present survived to form colonies based on regression of data from 687 colonies. Exclusion studies showed that many of the early colonies were probably destroyed by predation; the major predator responsible seemed to be adult Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae). Mortality before apple bloom was most important in controlling rosy apple aphid population growth but by itself is not sufÞciently reliable to prevent economic injury. Interplanting of extraßoral nectar-bearing trees did not increase biological control, and interplanting with 50% trees with extraßoral nectar glands reduced biological control. The number of leaf curl colonies in the 50% interplanted orchards was lower than in monoculture orchards, suggesting a preference of alate oviparae for more diverse habitats, supporting the resource concentration hypothesis but not at a level sufÞcient to prevent injury. Predation and parasitism after the formation of leaf curl colonies was not adequate to control rosy apple aphid populations. -
The Mechanism by Which Aphids Adhere to Smooth Surfaces
J. exp. Biol. 152, 243-253 (1990) 243 Printed in Great Britain © The Company of Biologists Limited 1990 THE MECHANISM BY WHICH APHIDS ADHERE TO SMOOTH SURFACES BY A. F. G. DIXON, P. C. CROGHAN AND R. P. GOWING School of Biological Sciences, University of East Anglia, Norwich, NR4 7TJ Accepted 30 April 1990 Summary 1. The adhesive force acting between the adhesive organs and substratum for a number of aphid species has been studied. In the case of Aphis fabae, the force per foot is about 10/iN. This is much the same on both glass (amphiphilic) and silanized glass (hydrophobic) surfaces. The adhesive force is about 20 times greater than the gravitational force tending to detach each foot of an inverted aphid. 2. The mechanism of adhesion was considered. Direct van der Waals forces and viscous force were shown to be trivial and electrostatic force and muscular force were shown to be improbable. An adhesive force resulting from surface tension at an air-fluid interface was shown to be adequate and likely. 3. Evidence was collected that the working fluid of the adhesive organ has the properties of a dilute aqueous solution of a surfactant. There is a considerable reserve of fluid, presumably in the cuticle of the adhesive organ. Introduction The mechanism by which certain insects can walk on smooth vertical and even inverted surfaces has long interested entomologists and recently there have been several studies on this subject (Stork, 1980; Wigglesworth, 1987; Lees and Hardie, 1988). The elegant study of Lees and Hardie (1988) on the feet of the vetch aphid Megoura viciae Buckt. -

Entomol. 40(6): 1541Ð1545 (2011); DOI: http://dx.doi.org/10.1603/EN10240 Downloaded from https://academic.oup.com/ee/article/40/6/1541/532414 by guest on 23 September 2021 ABSTRACT Thermal requirements (lower temperature threshold and thermal constant) for the development of each developmental stage of the predator Harmonia axyridis (Pallas) were studied on Aphis fabae Scopoli and Dysaphis crataegi (Kaltenbach) under controlled laboratory conditions. The effect of temperature (15, 20, 25, and 30ЊC) and prey species was examined on pre-imaginal developmental duration and life cycle (pre-oviposition period included) of the predator. Our results suggest comparable thermal requirements for the development of H. axyridis on the particular prey and when compared with other aphid species. The total preimaginal development of H. axyridis,at 15, 20, and 30ЊC, and its life cycle, at 15 and 30ЊC, are shorter on D. crataegi than on A. fabae.

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). -

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.
