Biocontrol of a red scale boosts citrus industry in North America | |||||
|
|
|||||
Problem Statement: Red scale was a serious pest affecting citrus crops because early attempts at control were ineffective. Methods: It was originally though that the red scale pest was Aonidiella citrina. However, taxonomic investigations revealed that red scale was in fact a closely related species, A. aurantii. This discovery provided the basis for further research, again drawing on expert taxonomic inputs, that led to selection of host specific parasitoids of the genus Aphytis. Outcomes and Impacts: The host specific parasitoids were eventually used successfully in control of red scale. Lessons: Taxonomic expertise was needed both for the correct identification of the red scale pest and for selection of parasitoids for biocontrol. | ||||||
