Leaf Rollers
Two kinds: Fruit tree leaf roller and oblique-banded leaf roller. They eat
40 kinds
of plants. Spring, summer or fall adult moths
lay egg clusters which are covered
with waterproof cement.
Some species hatch early and overwinter in cracks in
the
bark of host trees. Other species don�t hatch until spring. First few
weeks
after hatching while the green larve are about the size
of long rice grains, they
eat day and night. When half
grown, they begin to hide during the daytime by
folding leaves
together and feeding at night. At some point in maturity, a larva
pupates. From pupa - lite brown or green segmented clyinder
within rolled-up
leaf, emergers as adult moth. The
obligue banded leaf roller produces 1 - 2
generations a year.
A number of parasitic insects usually keeps population
down. Light infestation - pick by hand or use Bacillus thuringionsis.
