Abstract Genetic diversity is one of the most important issues in studies on conservation of cattle breeds and endangered species. The objective of this study was to estimate the levels of genetic differentiation between locally adapted taurine (Bos taurus taurus) and zebu (Bos taurus indicus) breeds in Brazil, which were genotyped for more than 777,000 SNPs. The fixation index (FST), principal component analysis (PCA), and Bayesian clustering were estimated. The FST highlighted genetic differentiation between taurine and zebu breeds. The taurine lines, Caracu and Caracu Caldeano, had significant genetic differentiation (FST close to 5%) despite their recent selection for different uses (meat and milk). This genetic variability can be used for conservation of locally adapted animals, as well as for breeding programs on zebu breeds. Introgression of zebu in locally adapted breeds was identified, especially in Curraleiro Pé-Duro breed. The Gyr breed, however, had low breed purity at genomic level due to its very heterogeneous mixing pattern. |

Considering the importance of Euschistus heros a soybean pest and the high incidence of the parasitoid Hexacladia smithii on this host, its influence on the survival and reproductive potential was evaluated. These two factors were compared under laboratory conditions (25C+2C, 65%+10% RH, 14L:10D) using healthy and parasitized females at different development stages (1,7 and 14 days of adult life). A strong influence of H. smithii parasitism on the reproductive capacity of E. heros females at the different ages studied was detected. Fecundity was drasticaly reduced when the parasitism occurred at the first day female adult life, when they are reproductively imature. During ca. 46 days, healthy E. heros females deposited an average of 66.92 eggs, (11.31 eggs masses/female), statistically higher than the values obtained for females parasitized by H. smithii at 1,7 and 14 days of adult life, when average values of 1,8.86 and 14.10 eggs per female, respectively. In relation to egg masses size there was significant differences among treatments. Althoug data had shown a tendency for bigger egg masses (5.71 eggs) for healthy females as compared to H. smithii parasitized females (1 to 4.24 eggs/egg mass). E. heros egg fertility was not affected by H. smithii parasitism when this occurred at seven (60.41%) and 14 days of adult life (71.40%) as compared to healthy females (94.22%). Parasitism supressed adult survival after 45 days, compared to 32% survival of unparasitized ones. These results indicate that parasitism by H. snithii affected the reproductive capacity of E. heros in all stages tested being its influence higher when the insect was immature (1 day) reducing the offsprings and causing high mortality to the host.
