Esta pesquisa foi conduzida no laboratorio de Controle Biologico da Coordenadoria Regional Sul do IAA/PLANALSUCAR, Araras, SP. Teve por objetivo determinar alguns dos parametros biologicos e a competicao intra-especifica das moscas Metagonistylum minense Towns., 1927, e Paratheresia claripalpis Wulp, 1896, parasitoides de broca-da-cana, Diatraea saccharalis Fabr., 1794. Foram feitas 1.000 inoculacoes com cinco repeticoes de 200 lagartas para cada especie, visando acompanhar a biologia destes taquinideos. O periodo larval medio para M. minense foi de 8,49 dias e a peso medio dos puparios "simples" foi de 39,52 mg. Para a especie P. claripalpis, o periodo larval medio foi de 10,48 dias, sendo o peso medio dos puparios "simples" de 53,73mg. Quanto a competicao intra-especifica, observou-se que ela e mais acentuada em P. claripalpis, onde o peso medio dos puparios "triplos" foi cerca de 50,94% inferior ao peso de puparios "simples", enquanto para M. minense esta reducao foi cerca de 42,73%. O numero medio de larvas geradas por femea da especie P. claripalpis foi de 374,46 +- 22,61, e de M. minense 438,86 +- 22,35. |

This study evaluated the effect of uterine health on the fertility of postpartum beef cows. Multiparous lactating Nelore cows (Bos indicus; n = 155) were subjected to a timed artificial insemination (TAI) protocol. Cows were included in a progesterone-estradiol based TAI protocol. On Day 0, before the beginning of the protocol, cows were subjected to evaluation of purulent vaginal discharge (PVD) and collection of uterine tissue using the cytobrush technique. Slides for polymorphonuclear (PMN) cells counting were prepared before the same cytobrush was used for RNA extraction and analysis of IL-1B, IL-6, IL-8, TNFa, GAPDH, and Bactin gene transcription. Cows were separated into 4 categories according to the proportion of PMN and PVD: 1) Healthy (HE; n = 87), cows with <- 4.75% PMN and PVD of 0; 2) Positive Purulent Vaginal Discharge (PVD+; n = 24), cows with < - 4.75% PMN and PVD >- 1; 3) Subclinical Endometritis (SCE; n = 29), cows with > 4.75% PMN and PVD of 0, and; 4) Subclinical Endometritis + PVD+ (SCEP; n = 15), cows with > 4.75% PMN and PVD ? 1. Cows in the HE group had a greater (P < 0.05) pregnancy per AI (P/IA) than cows in SCE and SCEP groups. However, P/AI in cows from the PVD+ group was not different in comparison to HE and SCE groups (P > 0.05). Cows from the SCE and SCEP groups had a higher (P < 0.001) proportion of PMN cells in the uterus than HE and PVD+ groups. Relative transcription of IL-6 and TNFa did not change among groups (P > 0.05). In contrast, transcription of IL-8 was greater (P = 0.02) in SCEP than HE and SCE groups. The relative transcription IL-1B was greater (P < 0.05) in SCEP than in PVD+, but the cows in the HE and SCE groups were not different from the other groups (P = 0.08). Our results demonstrate that postpartum beef cows, raised in the Amazon biome, with a higher proportion of PMN cells have lower fertility. Moreover, ~ 40% of the postpartum cows included in TAI programs early postpartum had suboptimal uterine conditions (subclinical endometritis, purulent vaginal discharge, or both).
