The relative importance of COVID‐19 pandemic impacts on biodiversity conservation globally

Abstract: The COVID‐19 pandemic has had an enormous impact on almost all aspects of human society and endeavor; the natural world and its conservation have not been spared. Through a process of expert consultation, we identified and categorized, into 19 themes and 70 subthemes, the ways in which biodiversity and its conservation have been or could be affected by the pandemic globally. Nearly 60% of the effects have been broadly negative. Subsequently, we created a compendium of all themes and subthemes, each with explanatory text, and in August 2020 a diverse group of experienced conservationists with expertise from across sectors and geographies assessed each subtheme for its likely impact on biodiversity conservation globally. The 9 subthemes ranked highest all have a negative impact. These were, in rank order, governments sidelining the environment during their economic recovery, reduced wildlife‐based tourism income, increased habitat destruction, reduced government funding, increased plastic and other solid waste pollution, weakening of nature‐friendly regulations and their enforcement, increased illegal harvest of wild animals, reduced philanthropy, and threats to survival of conservation organizations. In combination, these impacts present a worrying future of increased threats to biodiversity conservation but reduced capacity to counter them. The highest ranking positive impact, at 10, was the beneficial impact of wildlife‐trade restrictions. More optimistically, among impacts ranked 11‐20, 6 were positive and 4 were negative. We hope our assessment will draw attention to the impacts of the pandemic and, thus, improve the conservation community's ability to respond to such threats in the future

Extracts of the rosary pea, Abrus precatorius, are toxic to the invasive termite, Coptotermes gestroi

In 2009 an outbreak of the termite Coptotermes gestroi caused major damage to buildings and vegetation in Fiji. Termite control is most commonly performed using synthetic insecticides, although many botanically-derived toxins are also being evaluated. The woody legume, Abrus precatorius, contains the toxic protein abrin, and has been investigated previously for insecticidal properties. The current study used laboratory experiments to evaluate extracts of A. precatorius as potential control agents for C. gestroi. In Petri dish assays, exposure to water- and methanol-based extracts of leaf and seed material significantly increased mortality and shortened time to death of C. gestroi. The results suggest that extracts of A. precatorius have potential for use as control agents of C. gestroi and should be evaluated further to determine their mode of action and efficacy under field conditions

Potential of the weed Abrus precatorius Linnaeus(Fabales: Fabaceae) for control of insect pests in the South Pacific: a review.

Abrus precatorius L. (Fabaceae) is a woody legume plant that grows in tropical countries and is an invasive weed in other areas. Extracts of this plant have insecticidal properties against several arthropod groups including Coleoptera, Diptera, Hemiptera, Isoptera, Lepidoptera and Orthoptera. It also has inhibitory effects against other pests including fungal plant pathogens, parasitic protozoans and molluscs. Studies that have examined the efficacy of A. precatorius extracts against invertebrate pests found in the South Pacific region suggest that this plant may be a potential mean for controlling many important invasive agricultural pests. Harvest and usage of A. precatorius may serve a dual purpose to restrict weed growth whilst providing material to produce a botanically-derived insecticide
