La radiodisinfestazione del garofano dai Tortricidi dannosi.: Effects of ionizing radiations on the eggs of Epichoristodes acerbella Walk.

Abstract

The radiosensitivity of the eggs of Epichoristodes acerbella (Walk.) has been investigated in order to use ionizing radiations for treating infested cut carnations.
Doses from 5 to 70 krad have been applied to the eggs at 7, 4 and 1 day before hatching.
The main results achieved have shown:
- the doses of 7, 20 and 70 krad respectively applied on eggs of 2, 5 and 8 days of age caused a mortality of 100%;
- a dose of 13 krad on old eggs is sufficient to kill all insects in the crysalid stage;
- a dose of 10 krad induced a complete sterility of the adults obtained from treated eggs.
