Abstract
Effect of X-ray radiation on the development inhibition was evaluated for all stages of the life cycle of Helicoverpa armigera to determine a radiation dose for potential quarantine treatment against the insect. ED99 values for inhibition of hatching, pupation, and adult emergence from irradiated eggs were 413, 210, and 154Â Gy, respectively. ED99 values for inhibition of pupation and adult emergence from irradiated larvae were 221 and 167Â Gy, respectively. Pupa was the most tolerant to X-ray radiation. ED99 value for inhibition of adult emergence from irradiated pupae was as high as 2310Â Gy, whereas that for inhibition of F1 egg hatching was only 66Â Gy. ED99 value for inhibition of hatching of F1 eggs which were laid by irradiated adults was estimated to 194Â Gy. X-ray irradiation against H. armigera is recommended as an alternative method to methyl bromide fumigation for phytosanitary treatments during quarantine. X-ray radiation dose of 200Â Gy is proposed as a potential quarantine treatment dose for H. armigera eggs and larvae.
