The world's 100 worst invasive alien insect species
<ol> <li>While there has been great interest in species characteristics that promote invasiveness, still little is known about the characteristics that distinguish invasive from non-invasive insects. Using a database on the naturalized distributions of alien insects and expert opinions about their impacts, we identified the world's 100 worst invasive insect species.</li> <li>By comparing species characteristics reported in the literature using a meta-analysis, between the 100 worst invasive species and related non-invasive species, we found that invasive insects overall have more pathways of introduction, occur in more habitats, have higher fecundities, higher voltinism, more genes, shorted lifespans and faster development from egg to adult. Some of the differences in species characteristics are related to propagule pressures, life-histories and biotic interactions, conditional on whether the non-invasive species compared is known to be naturalized somewhere, whether the invasive species is globally distributed, and the climatic region of the species.</li> <li> <em>Synthesis and applications</em>: We show for the first time, using a multi-species comparative approach, that invasive insects differ in several characteristics from related non-invasive insects. Our results show that invasive species, such as Spodoptera frugiperda, typically are habitat generalists with a high fecundity, a short lifespan, and fast development, whereas the importance of female body size and number of enemies are context dependent. Our study can guide and improve existing screening tools for assessing the invasion potential of alien insects.</li> </ol>
Permits issued in respect of South Africa's National Environmental Management: Biodiversity Act's Alien and Invasive Species Regulations over the period October 2014–December 2022
<p>Data based on records of permits issued by the South African Department of Forestry, Fisheries, and the Environment (DFFE) to conduct activities on listed invasive species restricted under the NEM:BA A&IS Regulations of 2014<br> This is based on the file <Copy of Official AIS Permit Register (31 Aug 2019).xlsx> with updates to 2020 based on the updates in the file <AIS Permit Register Updated to 21 January 2021.xlsx> and updates to Dec 2022 based on the file <AIS Permit register updated up to 31 Decenber 2022.xlsx><br> Compiled for the purposes of the reporting process "The Status of Biological Invasions and their Management in South Africa", see http://iasreport.sanbi.org.za/ for more details.
