Utilizou-se a sincronização do estro com esponjas vaginais de 30mg de acetato de fluorogestona durante 12 dias para avaliar o efeito de diferentes doses de eCG sobre o desempenho reprodutivo de ovelhas. Na retirada das esponjas as ovelhas foram divididas em três grupos para receberem 0 (n=26), 200 (n=30) ou 400UI (n=30) de eCG. O estro foi detectado a cada 12h utilizando-se um rufião. As fêmeas foram inseminadas por laparoscopia 60h após a retirada das esponjas. Realizaram-se colheitas de sangue aos 5 e 18 dias pós-inseminação para dosagem de progesterona e determinação do número de ovulações e prenhezes, respectivamente. A fertilidade foi verificada por ecografia aos 60 dias e ao parto. Das 86 ovelhas 70,9% apresentaram estro. Essa porcentagem foi maior (P<0,05) nas fêmeas tratadas com eCG: 96,7% (400UI) e 76,7% (200UI) versus 34,6% (0 UI). O intervalo entre o final do tratamento e o início do estro foi maior (P<0,05) no grupo sem eCG, 54,7±6,3h versus 45,9±7,8h para 200UI e 40,4±10,3h para 400UI. Verificou-se menor (P<0,05) número de ovulações e prenhezes no grupo sem eCG. A não aplicação de eCG influiu negativamente no desempenho reprodutivo de ovelhas deslanadas.
[Estrus synchronization, ovulation induction and fertility in hairless ewes treated with equine chorionic gonadotrophin].
The aim of this experiment was to evaluate the effect of different doses of eCG on reproductive performance of ewes. The estrus was synchronized with vaginal sponges with 30mg FGA during 12 days. At the time of sponge removal, ewes were distributed in three groups: 0 (n=26), 200IU eCG (n=30) and 400IU eCG (n=30). The estrus was detected by aid of a vasectomized ram. The ewes were inseminated by laparoscopy, 60h after sponge removal. Blood samples were collected at 5 and 18 days after insemination, in order to determine progesterone concentration. It was observed 70.9% of ewes in estrus after the end of treatment. The females that received eCG showed higher (P<0.05) percentage of estrus: 96.7% (400IU) and 76.7% (200IU) versus 34.6% (0 IU). The interval between the end of treatment and estrus onset was higher (P<0.05) in the group that did not receive eCG (54.7±6.3h) in comparison to the groups that received 200IU (45.9±7.8 h) and 400 IU eCG (40.4±10.3h). A lower (P<0.05) number of ovulating and pregnant ewes in the group that did not receive eCG was observed. The eCG withdraw resulted in negative effect on reproductive performance of ewes.

Hypothenemus hampei (Ferrari) is an important pest worldwide. Methods of monitoring and control using baited traps are not yet established in coffee plantations in the Brazilian Amazon. The objective of this work was to record, for the first time, results of the use of baited traps in coffee plantation located in Rondônia, in favor of the control and pest monitoring. Two areas were delineated: i) with use of the traps baited with ethanol/methanol (1:1), treatment; ii) without use of traps (control). For comparison of results, two factors were considered: damaged fruits (damage by H. hampei) and infested (H. hampei inside of fruits). It was observed higher levels of damaged fruits per plants in the control area compared to the area where traps were used. The density of the pest population per plants found on infested fruits was also higher in the control area compared to the trapping area. These results suggest that traps baited with ethanol/methanol (1:1) are an effective alternative for population control of pest also in the coffee plantations in Rondônia, where there is no such management with this tool. Use of the baited traps to monitor the insect accurately revealed that the flight stimulus of the colonizing females is influenced by values of the environmental variables. According to the results, colonizing females are more active in the afternoon. Therefore, in order to achieve more efficient control of H. hampei, the best time to apply control agents is between 2:00 pm and 6:00 pm.
