and tobacco budworm control on cotton in large aerially applied plots and in 

 small plots treated with ground machinery. Weevil damage was reduced most 

 by Zolone (1.5 + 3.0), Carbaryl + Molasses + chlordimeform (1.50 + 0.125), 

 Lorsban (1.0), azinphosmethyl + methyl parathion (0.25 + 1.00) and CGA 18809 

 (0.50) (lbs + Al/acre in parenthesis). No weevil resistance to insecticides 

 was shown. Budworm damage was reduced most by FMC 33297 (0.05, 0.10 + 0.20). 

 RH 218 (1.00), CGA 15324 (1.00), Methorayl (0.75) and Acephate (1.00). Several 

 of the other compounds and mixtures resulted in reduced budworm damage to 

 bolls equal to the above materials, but square damage was more severe.

 Cotton aphid s, Aphis gossypii Glover, and cowpea aphids. Aphis caracclvora 

 Koch,, were more numerous on pilose cotton than on smoothier varieties. Aphids 

 were least numerous on mutant, bronze leaf, yellow green and virescent yellow 

 cottons. The leaf miner, Liriomyza munda Frick, was more numerous on pilose 

 cotton than on smoother cottons and least numerous on red leaf cotton. No 

 differences in parasitism of leaf miners were detected on the various cotton 

 types. Cotton fleahoppers, Pseudatomosce^ is seriatus Reuter, v;ere more numerous 

 on pilose cotton than on the smoother cottons. Not enough fleahoppers were 

 present in the colored cottons to detect differences. More fleahoppers were 

 present on Frego Bract cottons than on their normal counterparts. The fewest 

 fleahoppers were found on the heavily glanded XG-15; however, another heavily 

 glanded cotton, 39, had more fleahoppers than Bayou or Deltapine Sraoothleaf. 

 The cotton leaf preforator, Bucculatrix thurberiella Busck, was most numerous 

 on red leaf cotton and least on mutant. The boll weevil, Anthonomus grand is 

 Boheman, did less damage to pilose, bronze leaf and red leaf cotton. Diffe-
