importance of supercooling points in the overwintering of the horn fly and stable fly (diptera:muscidae).	supercooling points were determined for eggs, 3rd instars, pupae, newly emerged unfed adults and 3-d-old engorged laboratory reared adults of haematobia irritans (l.) and stomoxys calcitrans (l.). wild nondiapausing and diapausing pupae of h. irritans also were tested. mean supercooling points ranged from -28.0 degrees c for h. irritans eggs to -6.8 degrees c for h. irritans larvae. mean supercooling points of all h. irritans developmental stages were lower than those of comparable s. calcitrans ...	1997	9220676
population genetics and gene variation of stable fly populations (diptera:muscidae) in nebraska.	genetic variation in stable fly, stomoxys calcitrans (l.), populations from nebraska, canada, and texas was sampled. four of 12 allozyme loci were polymorphic, with an average of 1.7 alleles per locus. observed and expected heterozygosities were 0.086 and 0.070, respectively. nei's genetic distance between populations averaged 0.001 and ranged from 0.000 to 0.005. wright's f statistics revealed greater variation within than among populations. allele frequencies were homogeneous among temporal sa ...	1996	8667389
