THE EFFECT OF ULTRA-VIOLET RADIATION ON THE INVASION, SURVIVAL AND FERTILITY OF LARVAE OF HETERODERA ROSTOCHIENSIS BY C. D. GREEN and STEPHANIE PLUMB Rothamsted Experimental Station, Harpenden, Herts., England Suspensions of second stage (newly hatched) larvae of H. rostochiensis were exposed to ultra- violet radiation at doses from 16 to 16,000 µw-min/cm2 and of H. schachtii at doses from 500 to 16,000 µw-min/cm2. Both species were immobilised after 10,000 µw-min/cm2. The number of H. rostochiensis larvae invading and establishing in potatoes decreased to one tenth after 500 µw-min/cm2 and the numbers of males and females which developed decreased proportionately. Even after 500 µw-min/cm2 both the males and females were fertile. Ultra-violet radiation alters the physiology of living tissue, damages the cells or nuclei and, in large doses, disrupts the tissue. Some effects on an organism may not show until later in life when a tissue changes its activity. For example, larvae of Nippostrongytus muri.r and T richinella spiratis may fail to mature after inoculation, and females that become adult may be infertile (Keeling, 1960, Stowens, 1942). Also, when fourth stage Ditylenchus dip.raci were irradiated and injected into onion seedlings (Green & Webster, 1965) they multiplied more slowly than
