Abstract:

A study of the effect of light from ordinary electric light bulbs on egg deposition by the Oriental Fruit Moth was made on several varieties of peaches at New Brunswick and Moorestown, N. J. The lights were suspended above the trees in such a way that groups of trees received different degrees of illumination ranging from 0 to 10 or more foot candles. One tree in each of three tests was illuminated from above and below so that all parts of the tree received illumination of an intensity of 10 foot candles or more. The lights were burned nightly or at such times as the moths showed activity. A photo-electric relay and thermostat was used to switch the lights on and off at the desired light intensity and temperature in the orchard. The effect of the lights on egg deposition was measured by counting the number of injured twigs caused by first and second brood larvae and by the percentage of injured fruit at harvest. No repellancy of the moths was noted in any of the tests. No pronounced attraction of the moths by the light was evident either.
