ITS PARASITES, ffash. Ent. Soc. Proc. 12 (2): 72-73. 
During 3 years tobacco-horn worms ( Phi ege thon t ius sexta and 
P. guinque macul ata Haw.), when found feeding upon plants other than 
tobacco, were highly parasitized by Apan teles congregatus Say; but when 
they were found feeding upon tobacco plants, they were seldom parasitized. 
The author believes that the low parasitism was due to the toxic effect 
of nicotine in the tobacco.
