In this study, 144 bacterial strains were isolated from the intestinal tract of third instar larvae of <em>Allomyrina dichotoma</em>.

In 2015, we released parasitoids in three cities (Syracuse NY, Naperville IL, Boulder CO) while city arborists were simultaneously treating high-value street trees with insecticides.

We also hypothesized EAB densities would fall as non-treated ash died and would not subsequently rebound as insecticide treatments were removed from street trees due to the parasitism of biocontrol agents.

When left unchecked, salvinia forms dense mats on the water surface, limiting sunlight penetration and altering water quality that disrupt ecosystem processes. In 2016, salvinia was first reported in Lake Ossa, Cameroon, and by summer 2021, had expanded to cover almost 49 % of the lake’s 4,000-hectare surface. A multinational team initiated a biological control and monitoring program, importing the salvinia weevil, <em>Cyrtobagous salviniae</em> Calder &amp; Sands (Coleoptera: Curculionidae) from Louisiana, USA, in summer 2021. The objectives of this study were to: quantify the changes in salvinia cover and other floating vegetation, document the establishment and impact of the biological control program, and deliver a tool for near-real time monitoring of floating vegetation. We developed a satellite-based remote sensing application to document in near real-time the changes in coverage of floating vegetation. Using this tool, we quantified the reduction in the salvinia coverage by 80 % within three years of the release of the weevil. Field surveys in 2022 and 2023, demonstrated weevil establishment in the lake and widespread salvinia browning that was associated with weevil damage. Linear regressions of the percent cover of floating vegetation over time, demonstrated that after the weevil release, the rate of change decreased to −1.7 % per 60 days. Field monitoring and satellite imagery showed the establishment of a sedge (<em>Oxycaryum</em> sp., Cyperaceae) within the salvinia mat in late 2021. This secondary invasion slowed the reduction in coverage of floating vegetation from −1.7 % to −0.6 % per 60 days, and warrants further research. By late 2023, the revitalization of Lake Ossa restored fishing and transportation opportunities for the community, and also the comeback the emblematic African manatee. The success of the biological control of salvinia in Lake Ossa is not surprising due to its tropical conditions. However, it highlights the importance of early intervention and continuous monitoring.

One approach to this is pre-emptive biological control, involving the importation of classical biological control (CBC) agents for risk assessments and acquiring approval for their release prior to the expected arrival of their target pests. This aims to mitigate the economic and/or environmental consequences of a delayed biological control response to pest invasions. Guidelines to assess the feasibility of pre-emptive biological control for high priority pests were recently developed. Emerald ash borer (EAB), <em>Agrilus planipennis</em>, is an invasive woodboring pest of ash (<em>Fraxinus</em> spp.) in North America, European Russia and Ukraine, and is spreading westward into Europe, threatening the future of European ash (<em>Fraxinus excelsior</em>).

Three of the parasitoids; <em>Oobius agrili</em>, <em>Spathius galinae</em>, and <em>Tetrastichus planipennisi</em>, were found suitable for pre-emptive biological control. The fourth parasitoid, <em>Spathius agrili</em>, was found to have limited establishment in new environmental conditions, and was therefore deemed less suitable for pre-emptive biological control of EAB in Europe. This assessment can inform scientists and regulators in Europe on the most promising EAB parasitoids that should be considered for pre-emptive applications for importation and risk assessment to acquire pre-approval for immediate release should the target pest subsequently be discovered.
