Studies were made to determine whether insect eggs on the exterior surfaces of jet aircraft survive flights in the stratosphere. The first flight was at 40,000 feet for 8 minutes at Mach 0.82 (465 knots true air speed) and an air temperature of -57.; the second at 45,000 to 50,000 feet for 30 minutes with 12 minutes above Mach one and an air temperature of -60. Complete mortality of eggs of the yellow-striped army worm (Prodenia ornithogalli Guen.), a representative species of Phalaenidae, the only family reported as laying eggs on aircraft, was obtained in both tests. There was, however, a normal hatch of the cold-resistant eggs of the eastern tent caterpillar (Malacosoma americanum (F.)) under these conditions.
