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

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.

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
