Arkansas Agric. Exp. Stn. Bull. 829, 36 pp. 

 Several cotton fields were scouted weekly for cotton insect infestations and 

 relevant crop performance information in 1974 and 1975, using conventional and 

 innovative methods. Each field was scouted independently but simultaneously by 

 two scouts. About half of the fields also were scouted by two more scouts at 

 another time the same week. Counts included: 1) thrips by beating small plants 

 against a "beater box", 2) node to 1st square, 3) sets of small squares, 4) plant 

 bugs in terminals and squares, 5) predators in terminals, 6) bollworm-budworm 

 eggs and small larvae in terminals, 7) plant bugs on drop sheet, 8) predators on 

 drop sheet, 9) boll weevil-punctured squares, 10) bollworm-budworra-damaged squares, 

 11) squaring rates, 12) square size, 13) insect-mite infestations of leaves, 14) 

 damaged white blooms, 15) plant densities, and 16) plant height. Use of a back- . 

 pack suction machine (D-Vac®) was compared to terminal and drop-sheet sampling. 

 It proved to be about equally effective as the drop sheet in sampling for plant 

 bugs and predators, and was the only effective method for leaf hoppers. The drop 

 sheet technique was much more productive than examining terminals for plant bugs 

 and predators. However, statistical precision was not improved. Time required 

 for each stop and total time per field was recorded in selected fields. In others, 

 time required for each operation was recorded. 



512. . 1980. Role of entomology in reducing cost of cotton production in 



1980. Proc. 1980 Beltwide Cotton Prod. Res. Conf,, pp. 313-314. 

 The greatest opportunity for impact of Entomology on cotton production in 1980 

 lies in two areas: 1) Scouting, surveillance, and decision-making. This requires 

 lots of high-quality troops in the field. The growth of professionalism among 

 Pest Management Consultants is most gratifying, but much remains to be done before
