Table 1 Effect of acetone and petroleum ether Barnoof extracts on the energy budget of

The energy stored in the body, the coefficient of
metabolizable energy (CME), the efficiency o storage
of ingested energy [ESI(E)] and the efficiency of
storage metabolizable energy [ESM(E)] were determined
in Table 1, Table 2 and Table 3.
Table 1 shows that the gross energy stored in the
bodies of F
1
progeny significantly decreased at all
treatments to 52.79%, 76.45% and 60.17% from the
control treatment at the concentrations 0%, 1.5%, 3%
of acetone extracts respectively and significantly
decreased to 73.13%, 59.21% and 62.02% from the
control treatment at the concentrations 0%, 1.5% and
3 % of the petroleum ether extracts respectively. These
previous levels or data exceed or more significantly
increased when plant extract combined with the dose
rate 100 Gy in Table 2 and also with the dose level
150 Gy.
In most treatments on Table 3, the significantly
increase in the gross energy stored in the bodies of F
1
progeny higher from 52.79% from the control
treatment in acetone treatment Table 1 to 83.86% from
the control treatment when acetone only combined
with both dose levels 100 and 150 Gy (Table 2 and
Table 3). The gross energy stored in the bodies
significantly increased from 76.45% and 60.17% in
1.5% nd 3% acetone extract in Table 1 to 83.86% and
70.35 % from the control treatment when combined
with the dose level 100 Gy respectively in Table 2 and
increased to 136.89% and 123.86% from the control
treatment respectively when combined with the dose
level 150 Gy in Table 3. Also, increased from 59.21%
and 62.02% from the control treatment at the
concentrations 1.5% and 3% of petroleum ether
extract to 91.76% and 92.13% from the control
treatment when combined with the dose level 100 Gy
in Table 2 and increased to 112.85% and 118.37%
from the control treatment when combined with the
dose level 150 Gy. Then, the combined of gamma
irradiation with plant extract Barnoof cause the
increasing in the gross energy stored in body, these
results agreement with Shaurub et al (2001) and
disagreement with Seth and Sehgal (1992). Generally,
the energy stored in the bodies of treated F
1
progeny
with plant extract was lower than that stored in the
bodies of non-treated larvae (ones) than it was higher
when combined with 100 Gy and 150 Gy of gamma
irradiation, this might be due to the ability of treated
larvae to utilize efficiently the input energy as
indicated by highest ESI (E) and ESM (E) relative to
