Discussion
 Bigeyed bugs typically were common throughout most of the growing season

 in the soybean fields sampled in our study, with greatest population densities

 occurring near the end of the growing season. These results from Alabama and

 Florida are similar to previously published studies conducted in other states

 in the southern U.S. (Raney and Yeargan 1977, Dietz et al. 1976, Shepard et

 al. 1974a, Pitre et al. 1978). Bigeyed bugs apparently have a similar

 phenology in soybean throughout the region. Bigeyed bugs obviously are

 important, indigenous natural enemies of soybean pests in the southern U.S.

 Enhancement and conservation of their populations should be a major priority

 in soybean IPM programs.

 Nymphal populations were clumped in the fields sampled in this study,

which contrasts with the conclusion drawn by Waddill et al. (1974) that

populations were random and best described by the poisson distribution.

Differences between the studies may indicate that dispersion characteristics

of bigeyed bug nymphs change as a function of population density and/or

sample-unit size. However, our results from a wide-range of densities in a

number of fields over two growing seasons would be a strong indication that

clumping is typical for nymphal populations. Adult populations usually were

randomly distributed, but sometimes clumped. These results corroborate the

conclusions drawn by Waddill et al. (1974) that their populations are best

described as randomly distributed.
