Yellow stem borer is notorious pest of Rice

9. The body
of the larva
is cream
colored
and the
head is
reddish
brown.

10. The pupa is
yellowish white with
a tinge of green. It
turns dark brown just
before adult
emergence. The
pupal stage takes
place inside the
stem, and often
below the soil
surface.

12. FEMALE V/S MALE
 The female YSB moth  The male, gray or light
has a pair of black spots brown in color, is smaller

14.  Yello rice stem borer is.....
 pest of deepwater rice.
 found in aquatic environments
 continuous flooding.
 High nitrogenous field favors population buildup of the stem
borers.
 Fields planted later favors more damage by the insect pest that
have built up in fields that have been planted earlier.
 Stubble that remains in the field can harbor stem borer larvae and
or pupae.

15. Stemborers feed on the crop during the vegetative
and reproductive stages of the rice plant.
Excessive boring through the sheath can destroy the
crop.
Second instar larvae enclose themselves in body leaf
wrappings to make tubes and detach themselves
from the leaf and falls onto the water surface. They
attach themselves to the tiller and bore into the stem.

16.  Deadhearts or dead tiller that
can be easily pulled from the
base during the vegetative
stages
 Whiteheads during reproductive
stage where the emerging
panicles are whitish and unfilled
or empty
 Tiny holes on the stems and
tillers DRYING OF THE CENTER TILLER
 Frass or fecal matters inside the
damaged stems

17. The young rice crop
can be visually
inspected for
deadhearts in the
vegetative stages and
whiteheads in
reproductive stages.
Stems can be pulled
and dissected for
larvae and pupae for
confirmation of stem
borer damage.
