Evaluation of compounds for repellency of the multicolored Asian lady beetle (Coleoptera: Coccinellidae) in vineyards

The purpose of this data collection was to evaluate the efficacy of alternative compounds that may be suitable for use in vineyards as repellents to the Harmonia axyridis. Products were screened as repellants for MALB in short-term laboratory trials. Products that showed a repellency of ≥50% were evaluated for residual repellency 24, 48, and 72 h after application. Eight repellent compounds were then evaluated in field trials in commercial vineyards with high MALB populations. The number of MALBs on vines was counted 2–6 h and 24–28 h after application.
