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.
