Wisconsin Cranberry IPM Newsletter vou-eku, x-uoe-s, Julys, 1993 Integrated Pest management for Cranberries RAINFALL RECITAL Has this spring seemed wet to you? Have you pumped more water out of the marsh than you ever hoped to? . The National Weather Service reports that rainfall since April 1, 1993 has been roughly double the 30 year average. The following table shows rainfall totals and 30 year means by district. Actual rainfall amounts will vary widely within districts due to local conditions. District Last Since Normal week April 1 since (June 21) A ril 1 NW 0.6 15.2 9.7 NC 1.0 17.7 9.6 NE 1.1 15.2 9.6 WC 0.6 18.8 10.5 C 0.8 18.9 10.0 EC 1.4 17.3 9.1 SW 1.5 19.2 10. 1 SC 0.9 17.6 10.0 SE 0.6 17.1 9.5 Temperatures are also cooler than normal, about the same as 1992. Remember, 1992 was a record cool year. See the weather data on the back page. Bill Bland assures me the temperature data are accurate. He checked the original data. Teryl Roper, UW-Horticulture PEST PROFILE Cranberry Fruitworm, Acrobasis Vaccinii Riley (Lepidoptera: Pyralidae) belongs to the Snout or Grass Moth Family. This family of moths is the second largest in the order Lepidoptera and includes other well known species of insects such as Cranberry Girdler, European Corn Borer, Sod Webworms and Wax Moths. As you can see, members of this family exhibit a great deal of variation in appearance and habits. As cranberry plants began to bloom, you may have noticed an increase in moth (''miller'') activity on your marsh mainly due to Cranberry Girdler flight (besides some spanworms, fireworm and Sparganothis) but on occasion you can kick up a f'rtlitwolqyl moth. The frtlitwolnzl moth is nocturnal and during the daytime adults normally hide down among the vines unless disturbed (sort of like teenagersq. Their flight is very short and quick with jerky motions. Adults are approximately one-half inch long with distinct patches of white and dark brown (almost black in appearance) scales on their wings. As we discovered during the 1992 growing season (using an experimental pheromone) flight begins around the east of June and continues through at least the end of July. Peak flight coincided with peak bloom or during the first week of July in 1992. Only one generation occurs each year in Wisconsin. Egg laying begins as berries start to set and grow and may continue until August. Eggs are deposited singly under on of the lobes at the blossom end (calyx end) of the berry. Eggs appear clear when first laid, then turn yellowish as they develop prior to hatching. Hatch is said to occur in about three to five days depending upon temperatures. Newly hatched larvae are pale yellow-green with an amber head. Larvae chew small entrance holes usually near the stem end which they close with a silken window. As larvae mature in late August and September, then about an inch in lengthy they become bright green with a reddish tinge along the tops of their bodies. Larvae consume the seed cavity and pulp of five to seven berries leaving them filled with brass (waste
