ABSTRACT
Aims:
Lettuce and broccoli are high value vegetable crops in California. The western flower thrips, Frankliniella occidentalis on lettuce, and the cabbage aphid, Brevicoryne brassicae and the green peach aphid, Myzus persicae on broccoli are important insect pests that are frequently managed with chemical insecticides.
Observation:
Efficacy of various chemical insecticides and the entomopathogenic fungus Beauveria bassiana was evaluated against these pests in field studies in the Santa Maria area of California. Some insecticides varied in their efficacy against F. occidentalis from year to year and against different aphid species.
Conclusion:
A new insecticide sulfoxaflor provided good control of aphids on broccoli. Beauveria bassiana demonstrated a potential for broccoli and lettuce integrated pest management.
