Comprehensive records of the host-plant associations of Amorbus obscuricornis (Westwood) and Gelonus tasmanicus (Le Guillou), undertaken over three years at field sites in southern Tasmania, are presented for the first time. Also presented are the results of performance experiments conducted predominantly with native Tasmanian Eucalyptus species. Both insect species were found to be oligophagous for Eucalyptus. However, A. obscuricornis was found to feed more widely than G. tasmanicus; that is, the former species fed upon eucalypts belonging to the ash, gum and peppermint groups whilst the latter was confined to the ash and gum species of Eucalyptus in Tasmania. On the basis of collection records, A. obscuricornis was found to be abundant in both wet and dry sclerophyll forest habitats whilst G. tasmanicus was more abundant in wet sclerophyll forests. The wider degree of oligophagy exhibited by A. obscuricornis than by G. tasmanicus is suggested as being related to this species’ preference for floristically diverse habitats, for example dry sclerophyll forest. In addition, inter- and intraspecific host selection in the exclusively shoot- feeding A. obscuricornis was found to be positively influenced by the architecture, in particular the coppicing phenology, of hosts. The significance of factors such as plant architecture, resource abundance and nutritional quality to the host-plant associations of both species are discussed in relation to secondary chemistry and habitat preferences.

The Russian Far East

The Russian Far East (RFE) is an important hotspot of biodiversity whose insect fauna remains understudied, particularly its Microlepidoptera. Here we explore the diversity of leaf-mining micromoths of the family Gracillariidae, their distribution and host plant associations in RFE using a combination of field observations and sampling, DNA barcoding, morphological analysis and literature review.                We collected 91 gracillariid specimens (45 larvae, 9 pupae and 37 adults) in 12 localities across RFE and identified 34 species using a combination of DNA barcoding and morphology. We provide a genetic library of 57 DNA barcodes belonging to 37 Barcode Index Numbers (BINs), including four BINs that could potentially represent species new to science. Leaf mines and leaf shelters are described and illustrated for 32 studied species, male or female genitalia as well as forewing patterns of adults are shown, especially for those species identified based on morphology.                Three species, Micrurapteryx caraganella (Hering), Callisto insperatella (Nickerl), and Phyllonorycter junoniella (Zeller) are newly recorded from RFE. Five species previously known from some regions of RFE, were found for the first time in Amurskaya Oblast: Phyllonorycter populifoliella (Treitschke), Primorskii Krai: Ph. sorbicola Kumata and Sahkalin Island: Caloptilia heringi Kumata, Ph. ermani (Kumata) and Ph. ulmifoliella (Hübner). Eight gracillariid–plant associations are novel to science: Caloptilia gloriosa Kumata on Acer pseudosieboldianum, Cameraria niphonica Kumata on A. caudatum subsp. ukurundense, Parornix ermolaevi Kuznetzov on Corylus sieboldiana, Phyllonorycter ermani (Kumata) on Betula platyphylla, Ph. nipponicella (Issiki) on Quercus mongolica, Ph. orientalis (Kumata) and Ph. pseudojezoniella Noreika on Acer saccharum, Ph. sorbicola on Prunus maakii. For the first time we documented the “green island” phenotype on Phyllonorycter cavella (Zeller) mines on Betula platyphylla.                Two pestiferous species have been recorded during our surveys: Micrurapteryx caraganella on ornamental Caragana arborescens in urban plantations in Amurskaya Oblast, and the lime leafminer Phyllonorycter issikii (Kumata), a species known to be native to RFE and invasive elsewhere in Russia and in European countries.                A revised checklist of RFE gracillariids has been compiled. It accounts for 135 species among which 17 species (13%) are only known to occur in RFE. The gracillariid fauna of RFE is more similar to the Japanese fauna (49%), than to the fauna of the rest of Russia (i.e European part and Siberia) (32%).

A New Species

Thirty-nine species of sawfly (Symphyta) are recorded for the first time in Bulgaria. Most of these were collected during early spring of 2018, in the south-east of the country (Burgas and Varna Provinces). Empriaaridicola Macek & Prous, sp. nov. is described as new to science from specimens collected in several central, east and south European countries. Lectotypes are designated for Poecilosomaparvula Konow, 1892, Empriapravei Dovnar-Zapolskij, 1925 and E.pseudoklugi Dovnar-Zapolskij, 1929. Empriapravei and Sciapteryxbyzantina Benson, 1968 are at present only known in Europe from the coastal zone of the Black Sea. The new Bulgarian records of Hoplocampacantoti Chevin, 1986 and Neomessasteusloffi (Konow, 1892) represent large extensions in their recorded ranges, previously comprising respectively only northern France, and north-eastern Germany. Possible host plant associations are noted for several species, based on observations of adults.

The Psyllidae family is the most diverse within Psylloidea, with more than 1,300 species worldwide. Some psyllid species are important pests mainly of fruit trees, forest and ornamental plants. Despite being an economically relevant group, there are few studies on its biology, geographic distribution, natural enemies or host plant associations for many Argentinean psyllid species. This work records one species from Argentina for the first time, extends the distribution of another two psyllid species and provides information on host plants.

Much of the current knowledge on population biology and ecology of soilborne fungal pathogens has been derived from research based on populations recovered from plants displaying disease symptoms or soil associated with symptomatic plants. Many soilborne fungal pathogens are known to cause disease on a large number of crop plants, including a variety of important agronomical, horticultural, ornamental, and forest plants species. For instance, the fungus Verticillium dahliae causes disease on >400 host plants. From a phytopathological perspective, plants on which disease symptoms have not been yet observed are considered to be nonhosts for V. dahliae. This term may be misleading because it does not provide information regarding the nature of the plant–fungus association; that is, a nonhost plant may harbor the fungus as an endophyte. Yet, there are numerous instances in the literature where V. dahliae has been isolated from asymptomatic plants; thus, these plants should be considered hosts. In this article, we synthesize scattered research that indicates that V. dahliae, aside from being a successful and significant vascular plant pathogen, may have a cryptic biology on numerous asymptomatic plants as an endophyte. Thus, we suggest here that these endophytic associations among V. dahliae and asymptomatic plants are not unusual relationships in nature. We propose to embrace the broader ecology of many fungi by differentiating between “symptomatic hosts” as those plants in which the infection and colonization by a fungus results in disease, and “asymptomatic hosts” as those plants that harbor the fungus endophytically and are different than true nonhosts that should be used for plant species that do not interact with the given fungus. In fact, if we broaden our definition of “host plant” to include asymptomatic plants that harbor the fungus as an endophyte, it is likely that the host ranges for some soilborne fungal pathogens are much larger than previously envisioned. By ignoring the potential for soilborne fungal pathogens to display endophytic relationships, we leave gaps in our knowledge about the population biology and ecology, persistence, and spread of these fungi in agroecosystems.

Abstract Background Altica (Coleoptera: Chrysomelidae) is a highly diverse and taxonomically challenging flea beetle genus that has been used to address questions related to host plant specialization, reproductive isolation, and ecological speciation. To further evolutionary studies in this interesting group, here we present a draft genome of a representative specialist, Altica viridicyanea, the first Alticinae genome reported thus far. Results The genome is 864.8 Mb and consists of 4490 scaffolds with a N50 size of 557 kb, which covered 98.6% complete and 0.4% partial insect Benchmarking Universal Single-Copy Orthologs. Repetitive sequences accounted for 62.9% of the assembly, and a total of 17,730 protein-coding gene models and 2462 non-coding RNA models were predicted. To provide insight into host plant specialization of this monophagous species, we examined the key gene families involved in chemosensation, detoxification of plant secondary chemistry, and plant cell wall-degradation. Conclusions The genome assembled in this work provides an important resource for further studies on host plant adaptation and functionally affiliated genes. Moreover, this work also opens the way for comparative genomics studies among closely related Altica species, which may provide insight into the molecular evolutionary processes that occur during ecological speciation.
