A6 and A10, crochets uniserial, biordinal, ar-
ranged in a complete circle (Figure 5F). In
segments A1 to A8: Setae D1 and D2 near-
ly equidistant; seta D2 more than 2 x as long
as seta D1; seta SD2 very short compared
to SD1; L group trisetose (each in a unique
pinaculum). SV group in A1 to A6 trisetose,
while in A7 and A8 bisetose (all originate
from a common pinaculum). Segment A9:
seta D1 dorsal to seta D2; L group trisetose,
L1 and L2 very close to each other on a com-
mon pinaculum, and L3 on a separate pinac-
ulum; L2 more than 3.5 x as long as L1; seta
L3 nearly equal in length to seta L1.
Pupa
Maximum length 6.8 mm (n=8); brown, in-
tegument almost smooth.

larvae con-
sumed 29.6-38.4% of

farcta
pods in the
studied areas during 2008-2009 (Table 2). All
the seeds along the mesocarp of the pods
were completely destroyed (Figure 2E).
