Show ELECTRICITY TO KILL PE PESTS T I I First Experiments Made in dashing ton to Destroy Moths and Aphides by Incandescent Lights Some experiments s In electrocuting tree pests said to be the first ever eve made were recently conducted in tl the e estate state of Washington by V W. N. N Frost and J J. J C. C Lawrence In In t i six six-j oid old ear orchard many second brood od moths and green aphides were killed In a a. few minutes The apparatus af consisted consist consist- ed of or a storage battery and Inca des light cent-light globes of six candle power netted with fine steel wire coated with copper and tin Un alternately The globes were werft placed In the trees at the ends of covered wires and the moths flying Ing against them completing the electric circuit were killed and fell tell into receptacles beneath the globes Mr Frost estimates that one battery to an acre of ot trees will keep he moths under control dispensing with the usual spraying an saving many dollars He is preparing to wire hi his of ten acres containing seven hundred trees and some neigh neigh- neighbors bors will wUl do the same Seve Several al thou thou- and sand acres of or bearing apple trees will be thus equipped by spring if it com con mercial electric wires are nrc are extended to orchards the expense of batteries may mav be saved by making mattas direct connection with them I |
