diapause, pupation sites and parasitism of the horn fly, haematobia irritans, in south-eastern brazil.	in order to verify the occurrence of diapause, preference for pupation sites and hymenopteran parasitism, the pupae of the horn fly, haematobia irritans (diptera: muscidae), were collected from undisturbed cattle dung pats in pastures, and adults of the fly were sampled from cattle in são paulo state, south-eastern brazil, from april 1993 to july 1994. diapause was verified in 7.7% of pupae sampled from pastures in june and july of 1993 and in 9.9% of those sampled in may, june and july of 1994 ...	1999	10484164
variation in population density of horn flies (haematobia irritans irritans) (l.) (diptera: muscidae) in nellore cattle (bos indicus).	the population density of horn flies was evaluated in the year 1998 in the municipality of araçatuba, são paulo brazil, in relation to temperature and rainfall conditions. two lots of 30 nellore steers (bos indicus) were used which had no insecticidal treatment and were naturally infested with horn flies. the infestations were assessed by two counting methods, i.e., the traditional estimate method and the filming method. the highest fly frequencies were recorded in spring, summer, autumn and the ...	2003	14637033
molecular characterization and relatedness of haematobia irritans (horn fly) populations, by rapd-pcr.	haematobia irritans is a hematophagous parasite of cattle that causes significant economic losses in many parts of the world, including brazil. in the present work, one american and four brazilian populations of this species were studied by random amplified polymorpht dna (rapd) to assess basically genetic variability within and between populations. ten different decamer random primers were employed in the genomic dna amplification, yielding 117 fragments in the five h. irritans populations. in ...	2005	16010999
