The use of predacious mites for western flower thrips control in bedding plant production was demonstrated and release timing examined. Cost and efficacy comparisons were made between using a standard, calendar-based release program and one based on monitoring thrips levels. Acceptable thrips control was achieved with both methods but monitoring reduced costs by over 50%. Two new growers were introduced to using predacious mites for thrips control. Methods and results were presented to growers through two NY regional conferences and a national conference along with two newsletter articles. Data was also presented to CCE agents at a statewide in-service program.
