Mathematical models and numerical methods for the movement and life cycle of invasive pests across multiple scales
Invasive pests pose a significant threat to agriculture and native ecosystems. An important tool for managing these invasive pests is mathematical modeling, which enables forecasting of movements and the establishment potential of invasive species in an area, and can provide warnings to …

The ManhattAnt: Identification, natural history, and nutritional ecology of a recently introduced pest in New York City, Lasius emarginatus (Hymenoptera: Formicidae)
… for some of North America’s most damaging invasive pests, from chestnut blight to the Asian long-horned beetle. Despite these cautionary examples, there has been no formal research on a newly introduced ant species that was tentatively identified as a European ant species, <em>Lasius cf. …

Irrigators' Vulnerability to Drought in the Flathead River Basin, Montana
… crop water demand, and creating habitats for invasive pests and weeds. Further, drought will be increasingly problematic in irrigated areas as climate change continues to affect global climates and water resources. The Flathead River basin contains substantial areas of irrigated agriculture …

Exploitation of underexplored physiological, metabarcoding and evolutionary aspects to enhance invasive insect pest management
Invasive pests threaten agriculture and ecology of the invaded countries. To contrast and reduce their impact, entomologists develop specific and sustainable control strategies, which should target the pest and should not affect the surrounding environment. Therefore, a profound knowledge of pest …

The evolution and genetics of virus resistance in Drosophila
… viruses as biological control agents on the invasive species D. suzukii, one of the most important invasive pests of ripening fruits and wine production worldwide. Finally, I performed a genome-wide association analysis to investigate the genetic variation of resistance to the novel viruses …

Factors influencing the control of the Sirex woodwasp in South Africa
… Sirex noctilio is one of the most serious invasive pests of Pinus plantations in the southern hemisphere. Extensive control programs have been developed to manage this pest, of which biological control has been a major component. This thesis examined the factors that could influence the …

Simulated Emerald Ash Borer Induced Changes in Western New York Forests
Invasive pests and pathogens are among the biggest threats currently faced by Northeastern forests. The emerald ash borer (Agrilus planipennis) is one such pest and targets trees in the genus Fraxinus. The primary goal of this research was to determine the ecological effects of EAB on forests in …

Genome-scaled molecular clock studies of invasive mosquitoes and other organisms of societal relevance
… such as Anopheles and Drosophila, as well as to invasive mosquitoes Aedes aegypti and Aedes albopictus. Many other invasive pests are emerging worldwide aided by global trade, increased connectivity among countries, lack of prevention, and flawed invasive species management. Among them, there is …

Adaptation and hybridization in Helicoverpa crop pests
Invasive species threaten global food security and biodiversity. The process of biological invasion often results in secondary contact between closely related taxa, producing ‘experiments in evolution’. Evolutionary genetics can be used to study invasive species and inform their management. In this …

Ganaspis kimorum as a classical biological control agent for Drosophila suzukii: from laboratory studies to field assessments
… production faces constant threats from emerging pests. While globalization facilitates access to agricultural products worldwide, it also opens the door to the spread of new invasive pests, leading to significant economic losses. One of the most emblematic examples of such event, is given by the …
