Method Notes:
Climate Suitability Map
A Climate suitability map is now available. This survey should only be considered in the states with appropriate climate conditions and suitable hosts for this insect.
The map was produced by the SAFARIS Team. SAFARIS is a modeling framework that enables PPQ to quickly respond to emergencies, efficiently survey for pests, and assess potential pest impacts by collecting critical geospatial data and developing predictive models. SAFARIS is developed and maintained by the NC State University, Center for Integrated Pest Management (CIPM) with support from PPQ PERAL.
The SAFARIS team used a climate suitability model for cucurbit beetle occurrence in the continental United States, that was developed by PPQ PERAL and NCSU CIPM, to support CAPS survey planning. The model predicts the suitability of an area for cucurbit beetle occurrence based on the likelihood of favorable climate conditions for the insect occurring using tools and data within SAFARIS. The detailed method used in this assessment is described here.

Survey Recommendations
The following are recommendations for executing the survey using the approved methods for pest surveillance. The recommendations are developed through literature review and consultation with subject matter experts.
Key Diagnostic or Identification
Approved Method(s)
ID/Diagnostic:
Morphological: Diabrotica speciosa is almost identical to D. balteata which covers the whole southern U.S. in huge numbers. Confirmation by a Chrysomelid specialist is required.
Mistaken Identities:
Present in U.S.: Diabrotica balteata
Not present in U.S.: Diabrotica viridula, other pestiferous Diabrotica species in South America.
Not present in U.S.: Diabrotica viridula, other pestiferous Diabrotica species in South America.
