Mean numbers of P. ulmi eggs and motile stages surviving after the single release of T. setubali treatment at different release rates. a and b illustrates the mean number of eggs and motile stages recorded on the Skarlet cultivar every week after predatory mite release (0 days), with moderate initial density. c and d illustrates the mean number of eggs and motile stages recorded on Golden delicious, with high initial prey density. T/50: one release of T. setubali at the rate of 50/tree; T/100: one release of T. setubali at the rate of 100/tree; T/200: one release of T. setubali at the rate of 200/tree; Control: no release. The predatory mite releases were carried out on the 7th day of study
