used in the experiments. In one case 289 freshly hatched caterpillars 

 were caught on a surface of 977 square feet, the larvte having been 

 carried by wind from one-eighth of a mile to over one mile. In 

 another capture 346 caterpillars were caught on the sticky surface 

 of 1,614 square feet, blown a distance of from one-eighth of a mile 

 to thirteen and one-half miles.

 in spreading the wee mites (red spiders). It goes without saying 

 that we must take account of the action of wind in insect dispersion. 

 This argues forcibly for community action in fighting our insect pests.
