Considering Biology when Inferring Range-Limiting Stress Mechanisms for Agricultural Pests: A Case Study of the Beet Armyworm

Publication Date: March, 2018

We examined a published niche model for the beet armyworm, Spodoptera exigua, to assess its suitability for bioeconomic analyses of its pest threat, and identified issues with the model that rendered

The Potential Distribution of Cassava Mealybug (Phenacoccus manihoti), a Threat to Food Security for the Poor

Publication Date: January, 2017

We build upon and update a CLIMEX niche model by correcting inconsistent parameters and re-fitting it based on a careful examination of geographical distribution data and relevant literature. Further, we consider the role of irrigation, the known distribution of cassava production and a targeted review of satellite imagery to refine, validate and interpret our model and results.

"The Potential Global Distribution of Chilo partellus, Including Consideration of Irrigation and Cropping Patterns"

Publication Date: August, 2016

Chilo partellus is a major crop pest in Asia and Africa, and has recently spread to the Mediterranean region. Knowledge of its potential distribution can inform biosecurity policies aimed at limiting its further spread and efforts to reduce its impact in areas that are already invaded.

Population Dynamics and Management of Diamondback Moth (Plutella xylostella) in China: The Relative Contributions of Climate, Natural Enemies and Cropping Patterns

Publication Date: April, 2016

The model simulates the phenology and abundance patterns in the population dynamics across the climatic gradient in China reasonably well.

Long-run and Global R&D Funding Trajectories: The U.S. Farm Bill in a Changing Context

Publication Date: October, 2015

We present new evidence that today's middle-income countries—notably China, Brazil, and India— are not only growing in relative importance as producers of agricultural innovations through investments in public R&D, they are also gaining considerable ground in terms of their share of privately performed research of relevance for agriculture.

Research Investment Implications of Shifts in the Global Geography of Wheat Stripe Rust

Publication Date: October, 2015

Comparing the cost of developing stripe-rust-resistant varieties of wheat with the cost of stripe-rust-induced yield losses, we estimate that a sustained annual research investment of at least US$32 million into stripe rust resistance is economically justified.

The Potential Distribution of Invading Helicoverpa Armigera in North America: Is It Just a Matter of Time?

Publication Date: March, 2015

Helicoverpa armigera has recently invaded South and Central America, and appears to be spreading rapidly. We update a previously developed potential distribution model to highlight the global invasion threat, with emphasis on the risks to the United States.

Moving Matters: The Effect of Location on Crop Production

Publication Date: March, 2015

Our new spatial output indexes show that 16 to 21 percent of the increase in U.S. corn output over the 128 years beginning in 1879 was attributable to spatial movement in production.
