Visible mutation induction in Mormoniella by low frequency ultrasonic energy.

Abstract excerpt

Low frequency ultrasonic energy was utilized in an attempt to induce visible mutations in the parasitoid wasp Mormoniella vitripennis (Walker). Ultrasonic exposure at a frequency of 20,000 cycles per second was accomplished in aqueous medium with a commercially obtained energy source. Among the 22,396 progeny of exposed males and females, 63 phenotypically changed wasps were recovered. Three of these changes from...
