The International Journal of Tropical Insect Science (Int J Trop Insect Sci) is a peer-reviewed journal established in 1980 to promote insect science mainly in the tropics. This study aimed to provide a Bibliometric overview of Int J Trop Insect Sci publications and citations between 2012 and 2020, ending September 2020. A sample of 488 documents extracted from the Web of Science (WoS) was analysed using widely used bioclimatic indicators. The articles were written by 1726 authors. During this period, the most productive authors comprised S Roy, followed by S Ekesi, S Subramanian and M Tamo. The dominant keyword was ‘resistance’, followed by ‘Homoptera'. India took a leading position in Single Country Publications (SCP) while Kenya took the lead in Multiple Country Publications (MCP). Bibliometric analysis reveals vibrant collaboration between African and Western countries and active publication of multi-country authored articles. We conclude that there is an increasing trend for collaboration among different countries on the general topic of insect science. Research in insect science has the potential to impact both academic researchers and practitioners the knowledge use chain. This study will help researchers, journal editors, science policy makers managers, and others working in the biodiversity space and potential research gaps needing for further studies.

Bothalia: African Biodiveristy & Conservation is published by AOSIS for the South African National Biodiversity Institute (SANBI) and aims to disseminate knowledge, information and innovative approaches that promote and enhanve the wise use and management of biodiversity in order to sustain the systems and species that support and benefit the people of Africa. The journal was previously publishd as Bothalia, and had served the South African botanical community since 1921. However the expande mandate of SANBI necessitated a broader scope for the journal, and in 2017, the subtitle, African Biodiversity & Conservation was added to reflect this change.

Parthenium hysterophorus L. (Asteraceae), commonly known as famine weed in South Africa, is one of the most invasive weeds worldwide, accountable for losses to biodiversity, agriculture, the economy, and the health of livestock and human beings. The spread of this weed is not easy to manage or reverse. With globalization, trade, and human movement, it will continue to spread, allowing its range to expand into new areas. This weed has serious adverse effects on rangeland and agricultural crop production. Because of its unique characteristics, its invasiveness and competitive success rates are attributed to its high reproductive ability, fast growth rate, tolerance to environmental stresses, climate change adaptability, allelopathic potential, and unpalatability to animals. Parthenium hysterophorus dominates diverse habitats by spreading quickly as a contaminant of grain and other crop products and through farm machinery. It is widely distributed and has become problematic in various countries, including South Africa. It has successfully invaded several provinces in the country since its introduction in 1880. Since plant invasions are not universal, this study aimed to review research that has been conducted on the aggressive weed P. hysterophorus to understand the ecological characteristics that enable its successful establishment, the economic costs associated with its detrimental impacts, and to briefly assess knowledge gaps to improve its management strategies.

Invasive species typically establish in areas outside their natural distribution through accidental introduction and accidental release or escape. Some species are introduced legally for economic and social benefits such as recreational hunting, the pet trade and research through established permitting processes driven by appropriate laws and regulations. The aim of this study was to determine whether there is a trend in demand for regulated alien taxa based on permit requests and to ascertain the activities for which permits requested in order to infer the drivers of alien taxa demand in South Africa. We examined the Department of Environmental Affairs (DEA) species permitting application database records from October 2015 to February 2018. From the total of 1,390 permit applications during this period, 79.2% of the permits were issued for various economic and social activities associated with the following species: Red lechwe (Kobus leche leche, Gray), fallow deer (Dama dama Linnaeus), Grass carp (Ctenopharyngodon idella Valenciennes), Nile tilapia (Oreochromis niloticus Linnaeus) and rose‐ring parakeet (Psittacula krameri Scopoli). Our results suggest that economic activities such as hunting and sport fishing are driving the demand for some regulated species. We suggest reinforced monitoring and inspection for permit compliance for species sought to minimise potential escape.
