and insect damage amont the cotton varieties Tamcot SP-37, Lockett 4789A,

 Growth characteristics, production potential, and response to insect pressure 

 were compared in cotton varieties Tamcot SP-37, Lockett 77-4, Lockett 4789A, 

 and Lankart Sel. 611. Yields were significantly different, but varietal re- 

 sistance to the bollworm, Heliothis zea (Boddie) , boll weevil, Anthonomus 

 grand is Boheman, or cotton fleahopper, Pseudatomoscelis seriatus (Reuter) , 

 was not detected. The two new varieties, Tamcot SP-37 and Lockett 77-4, per- 

 formed best because they produced the most squares and bolls and had a faster 

 rate of square production in early season.

Little data exist on the bacterial flora of the cotton boll weevil, Anthonomus 

 grandis , which is a common insect pest to cotton farmers in the United States. 

 This investigation determined the total numbers of aerobic and anaerobic bacteria 

 in diapausing field-collected boll weevils and active adult laboratory-reared 

 boll weevils. Identifications were made of aerobic genera isolated from field- 

 collected and laboratory-reared boll weevils that had previously been surface 

 sterilized. The genera found, in order of decreasing frequency, in the field- 

 collected boll weevils were Lactobacillus , Erwlnia, Flavobacterium , Entcrobacter , 

 and Pseudomonas . The genera found, in order of decreasing frequency, in the 

 laboratory-reared boll weevils were Lactobacillus , Pseudomonas , Streptococcus , 

 Erwinia , Enterobacter , and Flavobacterium , Lactobacillus was the most frequently 

 found genus in both groups.
