Abstract:
Groups of 100 eggs (laid 6-24 hours
previously) of Cadra cautella, Corcyra
cephalonica, and Plodia interpunctella were
reared on 30 g of spikelets or kernels of Triticum
monococcum, T. dicoccum, and T. spelta in a
conditioned room at 26 ± 1 °C, 70 ± 5 % r.h.,
and photoperiod 16:8 (L:D). A higher mean
number of adults is observed when moths are
reared on kernels, except for C. cephalonica on
T. monococcum. The mean developmental time
is longer with spikelets except when P.
interpunctella is reared on T. monococcum. A
low number of adults of the three species is
observed on spikelets of T. dicoccum and T.
spelta. In fact kernels are covered by glumes and
inner glumes that hinder larvae feeding. The
highest number of adults of C. cautella is
observed on kernels of T. dicoccum (76.5 ± 7.8).
Few adults of this species emerge from spikelets
of T. dicoccum (4.7 ± 0.5) and T. spelta (4.5 ±
1.3). The mean developmental time is not
significantly different among kernels (from 49.5
to 54.2 days) and among spikelets (from 61.5 to
66 days) of the different species of cereals.
The highest number of C. cephalonica adults
is observed on kernels and spikelets of T.
monococcum and on kernels of T. dicoccum;
numbers are not significantly different (from 78.5 to 79.7 adults). A lower mean number of adults is
observed on spikelets of T. dicoccum
(28.2 ± 1.2) and T. spelta (28.5 ± 2) with a
longer mean developmental time, 96 ± 0.8 and
112.2 ± 3.2 days respectively. The shortest mean
developmental time is observed on kernels of T.
monococcum (54 ± 1.8). The highest mean
number of adults of P. interpunctella is observed
on kernels of T. dicoccum (71 ± 5.5) and of T.
spelta (70 ± 2.2) with mean developmental times
of 42 ± 0.8 and 36.7 ± 0.5 days respectively.
Few individuals develop on T. dicoccum
(5.2 ± 1.3) and T. spelta (2.2 ± 1.3) with mean
developmental times of 59.2 ± 5.4 and 42.5 ± 0.6
days.
