Our new publication presents a model that predicts the phenology and climate-based establishment risk for the spotted lanternfly (Lycorma delicatula), an invasive pest that poses a serious economic threat to multiple industries in the U.S., Canada, and Europe, including grape (viticulture), nursery, orchard, and hardwood. 🍇 🌹 🌿 🍎

Check out the near real-time forecasts at the USA National Phenology Network to help you know where and when to expect life stages of the pest in the contiguous US. Pay closest attention to areas with tree-of-heaven, SLF's preferred host plant! Early detection allows for rapid and cost-effective control measures. Forecasts are also available on the USPest.org system.

Our publication in Biology presents models of the potential invasive distribution of Calonectria pseudonaviculata, the most widespread and damaging pathogen of boxwood, a major evergreen shrub crop and keystone forest species. The models can assist with identifying areas to watch for the plant pathogen both regionally and globally, which is important for protecting native Buxus species and the horticulture industry.

A chapter that I collaborated on in the book "Tactical Sciences for Biosecurity in Animal and Plant Systems" has been published! The content focuses on reviewing how to design and implement an effective surveillance system for early detection, identification, and containment of invasive species that threaten agricultural resources.

My new publication in PLoS ONE introduces DDRP (Degree-Days, Risk mapping, and Phenological event mapping), which is a population modeling platform that integrates mapping of phenology and climatic suitability in real-time to provide guidance on both where and when invasive insect species could potentially invade the 48-state conterminous United States. The platform serves as an open-source and relatively easy-to-parameterize decision support tool to help detect new invasive threats, schedule monitoring and management actions, optimize biological control, and predict potential impacts on agricultural production. Currently we are using DDRP to model 15 high-priority invasive insects as specified by stakeholders at APHIS PPQ, and we are developing models for IPM insect pest species.

A book chapter that I co-authored in "Integrated management (IPM) of insect pests" was just published. The book volume focuses on advances in understanding insect species and landscape ecology, which provide the foundations for effective IPM.

In our chapter, we describe general concepts and methods of the systems approach using applied phenology (seasonal activities) modeling of insect pests. In other words, we describe how to break down the complex attributes of an insect's life cycle to better understand and model its activities and development. This knowledge is needed for sustainable, productive agriculture.
