Effect of X-ray irradiation on the F1 generation of Sitophilus zeamais Motschulsky and the germination rate of maize grain

Abstract Background The use of X-ray irradiation in the control maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) infesting stored was tested at 60, 70 and 80 KeV as part international concerted efforts to save production enhance food security. Investigations were done laboratory mean temperature relative humidity 29.2 °C 75.7%, respectively using three varieties maize. possibility that can affect viability grains when planted after weevil process also evaluated laboratory. Standard methods used achieve specific objectives, machine snap constituted exposure time for each dose. Results results revealed 10% mortality adult weevils 24 h 40% a period 7 days. result indicates moderate effect on mortality. Progressive increase recorded dose increased from 60 KeV. doses did not significantly ( P > 0.05) restrict S . emergence protect against damage flour production. There no difference pattern daily new progenies accumulated emergence. relationship between weight emerging require more analysis. Absence significant irradiated un-irradiated strongly suggests adversely seed viability, this gives technique an opportunity higher acceptability agriculture. Conclusions We recommend or its incorporation into integrated pest management system order effective post-harvest pest.
