Against R. dominica on Wheat and Barley]]>KhoshnoudH. NematiN. AmirniaR. GhiyasiM. Hasanzadeh GhourttapehA. TajbakhshM. TalatiF. SalehzadehH. 52008115Tissues of higher plants contain novel natural substances
that can be used to develop environmental safe methods for insect control.
In this study, ethanol extract from flowers of Verbascum cheiranthifolium
Boiss. (Scrophulariaceae) was examined for their effect on mortality
and progeny production against adults of Rhyzopertha dominica (F.)
on two commodities, wheat and barley. The botanical extract was applied
at five dose rates, which 0.25, 0.5, 1.0, 2.0 and 3% (w/v). Adults of
R. dominica were exposed to the treated wheat and peeled barley
at 25 °C and 65% RH and mortality was assessed after 24 h, 48 h, 7
day, 14 day and 21 day of exposure. Then all adults were removed and the
treated substrate remained at the same conditions for an additional 45
day after this interval, the commodities were checked for progeny production.
In two commodities mortality increased with the increase of dose and exposure
interval. Results indicated that on wheat, mortality was 100% after 14
days of exposure at the highest dose rate. Whereas, in the same conditions
mortality of adults on barley was 63%. Thus plant extract was more effective
against adults of R. dominica on wheat than application of barley.
Interestingly in two diets, complete suppression (100%) of the progeny
production was observed in the treated wheat and barley than in control
even in the lowest dose rate.]]>Abbassi, K., Z. Atay-Kadiri and S. Ghaout,200326232236Abbott, W.S.,192518265267Aldryhim, Y.N.,1990Tribolium confusum DuV. and Sitophilus granarius (L.)
