| Summary: | The results of the present study showed a significant effect of the host kind (corn , sugar beet) and larval instars on some nutritional parameters of Agrotis ipsilon under laboratory condition (28 ± 1 C and 65 ± 5% R.H) The Ist instar larvae exhibit higher average values of ECD & ECI and RGR which reached 85.51, 170.55 and 0.294 respectively and the 2nd , 4th and fifth larval instars showed higher average values of AD and reached 82.76 , 82.95 and 83.21 respectively. The results also showed that the larva reared on corn exhibit a higher average values of ECD and ECI and reached 47.77 and 89.09 respectively while the larva reared on suger beet showed a higher average value of AD and RGR. |
