“…For instance, climate, genetics, or soil conditions are thought to limit establishment of agents both within South Florida and more broadly into Central and North Florida (Center et al 2000, David et al 2020). These limitations may eventually be overcome by importing different biotypes of the same species [e.g., the importation of the Nepalese biotype of the Air potato beetle (Smith et al 2018)] or through the approval, release, and establishment of additional species of biological control agents.…”

Invasive species are a chief threat to native biodiversity and are only becoming more common with human globalization. This creates a need to understand the patterns in invasion biology, including where invasions are most likely to occur, which species are most likely to establish and spread, and what are likely to be the most influential ecological consequences. We examine these questions through the lens of South Florida, the continental region with the most invasive species across the globe. First, understanding why South Florida has so many invasives and how they are distributed across South Florida helps us to understand where we can expect similar levels of invasion to occur. Second, understanding which species are most likely to establish, spread, and have the greatest ecological impact informs which invasions we should be most concerned about. Finally, the history of control efforts and their relative success can help guide future management practices. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 54 is November 2023.

“…The search for cold-hardy genotypes may also be more efficient based on the assumption that intraspecific variation in temperature tolerance does not correlate with variation in host range (i.e., diet breadth). Two genotypes of the air potato beetle (Lilioceris cheni Gressit and Kimoto) (Coleoptera: Chrysomelidae), one collected in Nepal and another from China, exploit different environmental niches but share the same narrow host range [53,54]. Similarly, two genotypes of the planthopper (Megamelus scutellaris Berg) (Hemiptera: Delphacidae) introduced into the USA from two different climate sources, southern Argentina (cooler climate) and Paraguay (warmer climate), have the same narrow diet breadth [55,56].…”

Many weed biological control programs suffer from large-scale spatial variation in success due to restricted distributions or abundances of agents in temperate climates. For some of the world’s worst aquatic weeds, agents are established but overwintering conditions limit their survival in higher latitudes or elevations. The resulting need is for new or improved site- or region-specific biological control tools. Here, we review this challenge with a focus on low-temperature limitations of agents and propose a roadmap for improving success. Investigations across spatial scales, from global (e.g., foreign exploration), to local (selective breeding), to individual organisms (molecular modification), are discussed. A combination of traditional (foreign) and non-traditional (introduced range) exploration may lead to the discovery and development of better-adapted agent genotypes. A multivariate approach using ecologically relevant metrics to quantify and compare cold tolerance among agent populations is likely required. These data can be used to inform environmental niche modeling combined with mechanistic modeling of species’ fundamental climate niches and life histories to predict where, when, and at what abundance agents will occur. Finally, synthetic and systems biology approaches in conjunction with advanced modern genomics, gene silencing and gene editing technologies may be used to identify and alter the expression of genes enhancing cold tolerance, but this technology in the context of weed biological control has not been fully explored.

“…Often, there is sufficient variation in climatic tolerances among biological control agent populations in the native range, such that certain biotypes may be more suitable for introduction in a particular region. For example, Smith et al (2018) found that from among populations of Lilioceris cheni Grissit & Kimoto introduced into Florida, USA, for biological control of Dioscorea bulbifera L., a Nepalese biotype experienced greater overwintering success compared to a previously collected biotype from southern China, suggesting the former would be more suitable to the region. Additionally, failures of water hyacinth, Pontederia crassipes (Mart.)…”

Lack of successful biological control of alligatorweed, Alternanthera philoxeroides (Mart.) Griseb. (Amaranthaceae), by Agasicles hygrophila Selman & Vogt (Coleoptera: Chrysomelidae) in the USA is an emerging problem as A. philoxeroides expands into temperate climates due to poor cold tolerance of the beetles. Sourcing climatically suited biotypes of biological control agents is traditionally done through foreign exploration into their native range; however, surveying introduced populations may provide a cost‐effective and regulatory‐friendly alternative. To compare foreign biotypes to those established in the USA, two populations of A. hygrophila were collected from the coolest extent of their range in South America, and two populations were collected from stable populations in the southeastern USA. For comparing cold tolerance among introduced populations, eight populations were collected from across a climatic gradient. For all populations, cold tolerance was measured as a function of supercooling point, critical thermal minimum (CTmin), chill coma, and temperature‐dependent survival and development of eggs and larvae. Results of cold‐tolerance measures for North American populations were subjected to principal component analysis (PCA) to reduce dimensionality and detect trends in cold tolerance among populations. For foreign and locally collected A. hygrophila, South American populations were significantly more cold tolerant as measured by CTmin (Δ1.98 °C), chill coma (Δ1.95 °C), larval survival (Δ35.0%), and development time of eggs (24.7% faster) and larvae (17.4% faster) at 15 °C. Comparisons among North American populations found significant differences in cold tolerance across populations; however, results were less consistent than those observed for foreign populations. The first principal component (PC) explained 43.0% of variation in cold‐tolerance metrics and was strongly related to mean temperature of the coldest quarter. The use of a multivariate approach to evaluate and compare cold‐tolerance phenotypes provides strong evidence of local adaptation in introduced populations of A. hygrophila. However, South American populations may still provide the best chance for control of A. philoxeroides in northern infestations.
