Extensive surveys during the winter months in inland areas of Australia have greatly extended both the range and known hosts of Australia's two pest Helicoverpa species. H. punctigera was the more common species, being collected from c. half of the sites sampled. Here a further 47 plant species in 8 families are recorded as possible host plants; the majority (all except two) are new records of native hosts, and greatly extend the existing lists. H. armigera was less common, being recorded from c. 10% of the 554 sites sampled. This species was reared from 28 species in 10 plant families. Both moth species are recorded for the first time from various native plant species, predominantly in the Asteraceae and Fabaceae. The Goodeniaceae is also added to the host list of both species. Determination of the status of host plants is discussed.

Nameriophyes sapidae Xue & Zhang (Acari: Eriophyidae) was found on transplanted nikau palms, Rhopalostylis sapida (H. Wendl. & Drude) in Auckland, New Zealand and described as a new species (Xue & Zhang 2008). Although R. sapida is a native plant species, it was not known if this mite species was indigenous or adventive because it was collected only from transplanted palms in unnatural gardens in Auckland. A survey was undertaken of R. sapida and the Kermadec Island palm, Rhopalostylis baueri (Hook. f.) Wendl. & Drude in the northern part of the North Island and Chatham Island.

Urbanization contributes to the loss of the world's biodiversity and the homogenization of its biota. However, comparative studies of urban biodiversity leading to robust generalities of the status and drivers of biodiversity in cities at the global scale are lacking. Here, we compiled the largest global dataset to date of two diverse taxa in cities: birds (54 cities) and plants (110 cities). We found that the majority of urban bird and plant species are native in the world's cities. Few plants and birds are cosmopolitan, the most common being Columba livia and Poa annua . The density of bird and plant species (the number of species per km 2 ) has declined substantially: only 8% of native bird and 25% of native plant species are currently present compared with estimates of non-urban density of species. The current density of species in cities and the loss in density of species was best explained by anthropogenic features (landcover, city age) rather than by non-anthropogenic factors (geography, climate, topography). As urbanization continues to expand, efforts directed towards the conservation of intact vegetation within urban landscapes could support higher concentrations of both bird and plant species. Despite declines in the density of species, cities still retain endemic native species, thus providing opportunities for regional and global biodiversity conservation, restoration and education.

Abstract: The Pantanal Biome occupies 20% of the Brazilian territory extending its distribution over two Brazilian States, Mato Grosso and Mato Grosso do Sul. This Biome is one of Brazil's poorly known regions concerning insect gall and their interactions with host plants. In this study, we characterized for the first time the gall morphology, identified host plants and the gall makers from an area of Brazilian wetlands from Mato Grosso State, known as Pantanal Matogrossense. We sampled Pantanal Biome areas in Poconé municipality, along the Transpantaneira Road, Mato Grosso State, Brazil, in two expeditions, July 2012 and January 2013, with a total effort of 2 hours. We characterized 91 morphotypes of insect galls in 54 host plant species; 28 gall makers in 24 host plant species; the richest host plant families are Fabaceae, Myrtaceae, and Sapindaceae. Psidium guineense Sw. is the super host species. This area in Pantanal Matogrossense is the second in the richness of gall morphotypes (N=91) and average morphotypes/plant species (1.7), comparing phytophysiognomies. Additionally, 15 plant species are new record as host in galler-host plant interaction in the world. This number represents 30% of the total of host plant species sampled in Poconé. This inventory is new knowledge to the Pantanal Matogrossense and representing a unique testimony of insect-plant interactions consumed by the unprecedented fire that occurred in Pantanal Biome in the dry season of 2020.

AbstractDrosophila suzukii (Matsumura) (Diptera: Drosophilidae), was first detected in 2009 in the Okanagan Basin, British Columbia, Canada. During 2010–2016, 94 570 fruits of 35 non-crop species, from 12 plant families, were collected from 101 sites where adult D. suzukii flies were trapped, and incubated in a controlled environment. In total, 450 adult D. suzukii emerged from 62 of 929 fruit collections, and from 10 host plant species in five families, of which six species are native to the region. Five plant species are reported for the first time as hosts of D. suzukii, and 11 species for the first time as non-hosts. Measures of fly occurrence and infestation reveal it to be relatively abundant in five hosts and low in others. The fly reproduced in a succession of host plants, with first infestation of each from mid-July through mid-September, and was present until mid-October, but overwintering stages were not found. Degree-day accumulations for the infested period suggest that three to five generations of D. suzukii developed on non-crop plants and formed a large contribution to the annual increases observed in trap counts in a semi-arid cold winter climate, with implications for many strategies of pest management.
