captured tiny parasitic flies, and wasps, and plant lice, and similar light, 

 small-bodied insects. In fact, the insect specialists think that prohahly 

 such light insect v;ind drift will be found considerably hij^er than the 14,000 

 level at which they stopped their collections. 



The pink boll worm moth, which has been supposed to be a comparatively 

 weak flier with a decided tendency to stay down among the plants, was fo'und 

 as high as 3,000 feet in the air. 



According to Mr, B. R. Goad, the principal entomologist who had charge 

 of this investigation! there is no question that as this work is continued 

 and extended it will throw more new light on how many insects travel. Air 

 currents at the higher altitudes often become very swift compared to the winds 

 at the ground. Once aji insect gets up into suchfe,st currents of air, it may 

 be carried forward on them for hundreds of miles within a comoarativGly short 

 time. Then a descending current of air may' return it to earth whore it may 

 start a new center of infestation. 



These findings will probably have an important bearing on many of our 

 plans to fight insect pests.

AITNOUIT CEMENT : That is catching your insect facts on the wing J In telling 



you about this work of Uncle Sam's Naturalists Station was cooperating 



with the United States Department of Agriculture, This time wcok after next 

 we'll overhear soaothing else from Nature's laboratories.
