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.

Host Associations

An updated checklist of Iranian Encyrtidae (Hymenoptera, Chalcidoidea) is presented based on literature records from 1947–2016. The current list includes 159 species representing 48 genera. Parasitoid-host associations in Iran and distributional data are also provided. Twelve encyrtid species (7.55%) are known only from Iran but a high number of species (68 species, 42.77%) are widely distributed in the Palaearctic region. Four species previously listed from Iran, Metaphycus angustifrons Compere, 1957, Homalotylus ephippium (Ruschka, 1923), H. sinensis Xu & He, 1997, and Ooencyrtus kuvanae (Howard, 1910) are no longer considered present. Hosts of Iranian encyrtid species are tabulated by order and family, with the majority being Hemiptera (66.98%), followed by Lepidoptera and Coleoptera (each 9.44%), Diptera (6.60%), Hymenoptera (4.71%) and Neuroptera (2.83%). The majority of Encyrtidae known in Iran are parasitoids of the superfamily Coccoidea (46.22%). Host-plant associations of Iranian Encyrtidae are also tabulated, by plant family.

A New Species

We describe a new species, D. sonorae Heed and Castrezana from Sonora, Mexico in the repleta species group of Drosophila (Drosophilidae, Diptera). This species is morphologically similar to other members of the newly established D. longicornis complex, and the well-established D. longicornis cluster. Host plant associations, biogeography, and distributions of species in both the longicornis and mulleri species complexes are discussed here.

Five Tribes

The higher classification of the mirid subfamily Bryocorinae has received comparatively little attention. It is not highly species-rich in comparison with other mirid subfamilies but does exhibit extraordinary morphological heterogeneity. In this work we provide a synthesis of the subfamily on a global basis, providing a new key and updated diagnoses of supraspecific taxa. Five tribes are recognised: Bryocorini, Dicyphini, Eccritotarsini, Felisacini and Monaloniini. The genus Campyloneura Fieber is transferred from the tribe Dicyphini to the Eccritotarsini. Analysis of distributional patterns and a survey of host plant associations are provided. Available data on distribution of the main bryocorine lineages are summarised in tabular form and evaluated using UPGMA methods, and geographically structured patterns were detected. The synthesis will enable users to identify bryocorines to tribal level with confidence and provides a classificatory framework for future revisionary and phylogenetic studies.

The Sericothripinae is a largely tropical group of about 140 species that are often strikingly bicoloured and have complex surface sculpture, but for which the biology is poorly known. Although 15 genera have been described in this subfamily, only three of these are currently recognised, with five new generic synonymies indicated here. In Australia, Sericothrips Haliday is introduced, with one European species deployed as a weed biological control agent. Hydatothrips Karny comprises 43 species worldwide, with six species found in Australia, of which two are shared with Southeast Asia, and four are associated with the native vine genus, Parsonsia. Neohydatothrips John comprises 96 species worldwide, with nine species in Australia, of which one is shared with Southeast Asia and two are presumably introduced from the Americas. Illustrated keys are provided to the three genera and 16 species from Australia, including six new species [Hydatothrips aliceae; H. bhattii; H. williamsi; Neohydatothrips barrowi, N. bellissi, N. katherinae]. One new specific synonym is recognised [Hydatothrips haschemi Girault (=H. palawanensis Kudo)], also four new generic synonyms [Neohydatothrips John (=Faureana Bhatti; Onihothrips Bhatti; Sariathrips Bhatti; Papiliothrips Bhatti); Sericothrips Haliday (=Susserico- thrips Han)].
