“…Therefore, information about the impacts of climate on the field performance of these biological control agents is needed for classical biological control programs. 26 Identifying environmental variables that influence the distribution and successful release of potential biocontrol agents is crucial for developing biocontrol programs targeting invasive pests, especially in areas without effective biocontrol agents available. The ecological niche models provide an effective method to predict the potential distribution of species with their known geographical distribution and climatic variables.…”

BackgroundThe biological control agent Phytoseiulus persimilis is a commercialized specialist predator of two agricultural pest mite species Tetranychus urticae and Tetranychus evansi. Biocontrol of these pest species by P. persimilis has achieved success in biological control in some areas. However, the lack of precise information about the influence of global climate change on the worldwide distribution of this biocontrol agent hampers international efforts to manage pest mites with P. persimilis. With 276 occurrence records and 19 bioclimatic variables, this study investigated the potential global distribution of P. persimilis.ResultsThe results demonstrated that the Maximum Entropy (MaxEnt) model performed well, with the area under the curve being 0.956, indicating the high accuracy of this model. Two variables, the minimum temperature of the coldest month (Bio_6) and precipitation of the coldest quarter (Bio_19) were the most important environmental variables that influenced the distribution of P. persimilis, contributing more than 30% to the model, respectively. The suitable area currently occupies 21.67% of the world's land area, spanning latitudes between 60°S and 60°N. Under shared socio‐economic pathway (SSP) 5‐8.5 (high‐carbon emissions), the low suitable area would increase by 1.31% until the 2050s.ConclusionThis study successfully identified that south‐eastern China, parts of countries in the Mediterranean coastal regions, including Libya, Algeria, Portugal, Spain, and France, are climatically favorable regions for P. persimilis, providing valuable information about the potential areas where it can be effectively exploited as biocontrol agents in classical biological control programs to manage pest spider mites environmentally friendly. © 2024 Society of Chemical Industry.

Cycads hold important economic and conservation value. Some species are extensively used in landscaping, while others are endangered and legally protected. The Australian cycad-attacking weevil, Siraton internatus, is notably destructive, occasionally causing infestations and invasions across various countries. This study simulated habitat suitability for S. internatus to assess its potential invasion and the impact of climate change. Habitat suitability was evaluated under current climate and four climate change scenarios over two time frames (2050 and 2090). Furthermore, we investigated the threat posed by S. internatus to cycad reserves, using Taiwanese reserves as a representative case. Our MaxEnt predictions demonstrated high accuracy, meeting multiple evaluation criteria. We explored the potential distribution of S. internatus within Australia and internationally, identifying suitable habitats in Africa, the Americas, Asia, and Europe. The case study highlighted the low habitat suitability within the two Taiwanese cycad reserves, which is projected to decrease to unsuitable levels under future climate change scenarios for this weevil species. Moreover, our results revealed that suitable habitat for S. internatus is projected to contract globally under all climate scenarios and time periods, but expansion in Chile and the southern Himalaya (e.g., Nepal). This study provides valuable insights into cycad conservation and pest invasion risks. The results support both global and local efforts to manage the invasion threats from this destructive Australian cycad-attacking weevil species. It also accentuates the urgency for continuous biosecurity inspections and prevention of exporting mature cycad caudexes from Australia.

BACKGROUND The spotted lanternfly (Lycorma delicatula), a significant agricultural and forestry pest, poses concerns due to its potential for rapid spread in favorable environments. Originating from East Asia, its distribution and ecological impacts in various regions, including Taiwan, remain subject to uncertainty. This study employed a comprehensive methodology combining field surveys, museum specimen analysis, and ecological niche modeling to assess the presence and potential invasion risks of L. delicatula in Taiwan.RESULTS Despite extensive surveys over two years and thorough reviews of museum collections, which were estimated by iNEXT3D analysis to ensure survey completeness, we found no conclusive evidence for the presence of the species in Taiwan, challenging previous controversial records. Ecological niche models indicate that, under current climate conditions, L. delicatula might find suitable habitats primarily in specific high-altitude areas, while coastal and lower elevation zones generally show low suitability. Additionally, in Taiwan, most regions where the host plants of L. delicatula were recorded exhibited extremely low habitat suitability. Global climate change predictions suggest a possible northward shift in suitable habitats, and the existing limited suitable habitats in Taiwan may further decrease as climate change progresses.CONCLUSION However, concerning the relatively higher suitability for the species in particular mountainous areas, continuous monitoring and further research are recommended to conduct for better understanding the risk and preparing for potential future scenarios.
