Volume 54 Number 18 Date 08/28/2009 APPLE MAGGOT - Emergence continued in the southern counties where unprecedented numbers of flies were registered this month. High counts for the week were 51 flies on an unbaited red sphere at Rochester in Racine County and 48 flies on a baited red sphere at Mequon in Ozaukee County. Growers are cautioned not to cease controls prematurely. Apple maggot activity can be expected through mid-September. CODLING MOTH - Economic counts of 5 or more moths per trap were documented at fewer apple orchards in the last monitoring period, but numbers remain extremely high in some areas. Near Dodgeville in Iowa County, 68 moths were reported from August 21-27. Growers who continue to experience high numbers of these insects may need to reevaluate the effectiveness and timing of their codling moth management programs to account for late-season activity. -- Krista Hamilton, DATCP Entomologist CRANBERRY REPORT - Despite an irregular bloom period, cranberry growers are optimistic about fruit potential this season. Fruit concentrations are reported as good to excellent at most sites, but size is variable depending upon cultivar. Fruitworm infestations and fruit rot are secondary to weather concerns at this point in the season. Heat units and a late frost are needed for berries to mature and for full yield potentials to be realized. --Tod Planer, WSCGA Whole Farm Conservation Project
