effects of caffeine on mating frequency and pre-copulation and copulation durations in drosophila prosaltans.	parameters of sexual behaviour were studied in drosophila prosaltans treated with 2,500 micrograms/ml of caffeine per 1 ml of banana culture medium. the mating frequency and copulation duration were greater in control than in treated flies, while the pre-copulation duration was greater in treated flies than in controls. statistical analysis showed that for the pre-copulation duration the difference was significant.	1995	8689898
the development of resistance to caffeine in drosophila prosaltans: productivity and longevity after ten generations of treatment.	the productivity of drosophila prosaltans treated with six concentrations of caffeine (from 50 micrograms/ml to 2,500 micrograms/ml of culture medium) during ten generations (approximately 8 months) decreased in a dosage dependent manner in every generation, but at the end of the treatment the flies in all experiments recovered normal productivity, except for those treated with 2,500 micrograms/ml. longevity in the tenth generation was significantly reduced in males and females only in the 2,500 ...	1998	10384710
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
