                         INSECT CONTROL IN BLUEBERRIES


               Suggested Control Program and Description of Pests

Blueberry production has increased steadily in the state of Florida with 500
acres of planted blueberries and 200 acres old enough to produce fruit.
Blueberries in Florida have few insect problems but as the industry grows it
is expected that the insect problems will also increase.

Homeowners who grow blueberries near or next to vegetable gardens will find
that foliage-feeding insects will migrate to blueberries on occasion and
carbaryl (Sevin) 50% WP applied at rate of 2 tablespoons to 3 gallons of water
should give control or malathion 57% WP at 3 tablespoons to 3 gallons of water.

BLUEBERRY BUD MITES are are tiny mites approximately 200 microns in length and
require a strong hand-lens to see them.  They approximate the citrus rust mite
in size.  This mite attacks the buds which become closely packed or rosetted
on the stem and then fail to expand and bloom.  This results in berry and leaf
loss.  Affected berries appear roughened and malformed.

THRIPS are tiny insects that can be a problem in early spring in north and
central Florida.  They damage the plants by laying eggs in young terminal
shoots. Thrips' populations can be monitored by using white PVC pipe, mounted
vertically at 3-5 feet covered with saran wrap and then apply a sticky
material.

BLUEBERRY FLEA BEETLES AND PLUM CURCULIO adults feed on foliage and buds, and
the larvae feed on foliage.  Plum Curculio can produce fruit damage in both
adult and larval stages.

CRANBERRY FRUITWORMS are small moth larvae of the family Pyralidae
approximately three-fourths of an inch in length (18-20 mm). Their color is
mostly green and may be rosy pink on top and grass green below.  Head is
yellowish to light brown. These insects have been known to produce
considerable fruit loss in other states.
\h 1 'Bird Repellents'



                                Bird Repellents

In January 1983, methyl carbamate (Mesurol) was approved for use on
blueberries as a repellent for robins, starlings, grackles, redwings,
bluejays, finches and other pest birds.  The 75% WP is applied at a rate of 2
to 2 2/3 pounds per acre.  Follow label directions carefully as product is
toxic to fish and wildlife.
