“…First, we compiled a taxonomic checklist that accounted for all species of parasitoid wasps ( Hymenoptera ) that have either been deliberately or accidentally introduced into New Zealand using the recent publications of Edney-Browne et al 2017 , Ward and Edney-Browne 2015 . Second, all specimens of the introduced species were located in the NZAC and information on specimen labels manually transcribed into an internal collection management system to form the 'dataset'.…”

The introduction of species to new regions is occurring at an increasing rate. These introductions typically consist of species that are deliberately introduced for the purposes of biological control of pests or of species that are accidentally introduced through human-mediated transport networks. Understanding the potential and actual impacts of these introduced species requires comprehensive information on their geographic distributions and biological associations. However, apart from a few well-known case studies, such information is lacking for many introduced species which severely hinders further assessment of risks and impact. A dataset is provided on host associations, geographic distributions and dates of collection for both deliberately and accidentally-introduced parasitoid wasp species (Hymenoptera) in New Zealand. Information was obtained by digitising specimens from the New Zealand Arthropod Collection. Dates of records range from 1921 to 2017. The dataset includes 1265 specimen records, representing 127 parasitoid species from 12 families, with host records for 177 host species from 61 families and eight insect orders. These data provide baseline information to help evaluate the risk from introduced parasitoids to non-target and native species.

“…Most records of deliberately-introduced species are between the periods of 1960-1970s and 1980-1990s, periods that correspond with the greatest number of programmes to introduce and release biological control agents (Charles 1998).…”

“…In addition, a lot of studies provided evidence that warming is significantly related to native species in urban areas [27,28], while the environmental effects on non-native species need to be further studied. Studies had further revealed the complexity and specificity in the establishment processes for non-native species, such as the more significant impacts of connectivity of host plant patches, the number of international tourist arrivals, exotic vegetation cover, and regional GDP on invasive species than on native species [29,30]. However, phenotypic plasticity and resource availability can allow non-native pest species to succeed across heterogeneous environments, such as urban forest ecosystems.…”

Since China experienced a rapid and unprecedented process of urbanization and climate change from 1978 onwards, pest outbreaks were frequently reported on urban forests, which reflects a significant imbalance between natural regulation and human control. Based on information extracted from all journal articles and reports about insect pests on camphor tree (Cinnamomum camphora) in urban China, we characterized historical patterns and trends in pest outbreaks over large areas. Our results suggested that (1) most distribution areas of C. camphora in urban China had pest records (14 provinces) over the last 50 years, especially at the south-eastern coastal areas; (2) pests on camphor tree in urban China showed an accelerated growth since the 1990s; and (3) pests on camphor tree in urban China were characterized by native and leaf-feeding species. Urbanization seems to positively correlate with urban pest outbreaks. Changes of urban pest outbreaks could largely be described by synchronic changes of socio-economic indicators, of which CO 2 emissions as metric tons per capita is the most significant predictor, followed by GDP and human population. Thus, managers and city planners should allocate resources to socio-economic-related pest outbreaks for a sustainable ecosystem.

1. Although most populations of non-native species arriving in new environments fail to establish, mechanisms behind failed biological invasions are still poorly understood. 2. Propagule pressure has been found to be a dominant driver of establishment success, underpinned by processes such as stochasticity and Allee effects. While studies have revealed the presence of a component Allee effect in field populations, empirical support for demographic Allee effects has been limited. 3. We used the leaf-feeding beetle Neolema ogloblini, a biological control agent against the plant Tradescantiafluminensis, as a proxy invasive species to experimentally study the process of establishment. We investigated how the initial size of the population released affects the probability of establishment and population growth in the first season after introduction at isolated sites in New Zealand. 4. The probability of establishment was found to increase with numbers of individuals released. A significant quadratic relationship was found between population size released and per capita population growth rate; that is per capita population growth rate initially increased as population size released increased but decreased at higher population levels. 5. These results support the presence of a demographic Allee effect. However, as the influence of stochasticity (environmental and demographic) could not be completely separated from that of a demographic Allee effect, we conclude that extinction probability in the experimental populations of N. ogloblini was influenced by both a demographic Allee effect and stochasticity. 6. Our study demonstrates and supports the concept that experimental biocontrol agent releases can be used for testing hypotheses regarding invasion biology.
