Synchronized estrus can be induced by different hormonal protocols including prostaglandin, progestagens, and gonadotrophins. Equine chorionic gonadotrophin is a FSH-like hormone produced by pregnant mares that can evoke antibody formation in goats. Thus, if possible, restriction of its use should be considered. The aim of this study was to investigate the possibility to omit the administration of eCG to induce estrus in Anglo- Nubian goats during the transition season. This study was done in February of 2009 in Espírito Santo do Pinhal/SP (22°57?S latitude and 46°58?W longitude), Brazil. The local breeding season extends from March to June. A total of 10 nulliparous and 10 pluriparous Anglo-Nubian goats were equally assigned into 2 treatments with (T1) or without (T2) 200 IU eCG (Novormon 5000®, Intervet Schering Plough Animal Health, São Paulo, Brazil) i.m. administration 24 h before sponge removal. All goats received (Day 0) intravaginal sponges (60 mg of MAP; Progespon®, Intervet Schering Plough Animal Health) and 50 mg d-cloprostenol (Ciosin®, Intervet Schering Plough Animal Health) i.m. Estrous behavior and transrectal ultrasonography (5-MHz transducer; Aloka SSD 500®, Tokyo, Japan) were performed at 12-h intervals (0600 and 1800h) until 96 h after sponge removal. Statistical analysis was performed using all tests at the 95% confidence interval with a SAEG® program (Funarbe, Viçosa, Brazil). Estrous response was 100% (10/10) for T1 and 70% (7/10) for T2 (P > 0.05). All animals that were detected in estrus ovulated, and none of the 3 that did not show estrus ovulated. The interval from sponge removal to estrous onset (h) was 36.0 ± 9.8 (T1) and 34.8 ± 10.5 (T2), whereas its duration (h) was 27.4 ± 14.5 (T1) and 32.6 ± 12.7 (P > 0.05). The interval from sponge removal to ovulation (h) was 67.0 ± 8.0 (T1) and 73.9 ± 6.4 (T2). Also, the interval from estrous onset to ovulation (h) was 25.2 ± 8.85 (T1) and 30.9 ± 6.4 (T2). No difference (P > 0.05) was observed in the number of ovulations for T1 (1.2 ± 0.4) and T2 (1.4 ± 0.5). The diameter of the ovulatory follicle (mm) was similar (P > 0.05) for T1 (6.7 ± 0.6) andT2 (6.5 ± 0.6) (P > 0.05). Further studies should be done to consider if the use of eCG is necessary in the transition season for Anglo-Nubian goats.

The sugarcane borer (Diatraea saccharalis, Fabricius, 1794) is a devastating pest that causes millions of dollars of losses each year to sugarcane producers by reducing sugar and ethanol yields. The control of this pest is difficult due to its endophytic behavior and rapid development. Pest management through biotechnological approaches has emerged in recent years as an alternative to currently applied methods. Genetic information about the target pests is often required to perform biotechnology-based management. The genomic and transcriptomic data for D. saccharalis are very limited. Herein, we report a tissue-specific transcriptome of D. saccharalis larvae and a differential expression analysis highlighting the physiological characteristics of this pest in response to two different diets: sugarcane and an artificial diet. Sequencing was performed on the Illumina HiSeq 2000 platform, and a de novo assembly was generated. A total of 27,626 protein-coding unigenes were identified, among which 1,934 sequences were differentially expressed between treatments. Processes such as defence, igestion, detoxification, signaling, and transport were highly represented among the differentially expressed genes (DEGs). Furthermore, seven aminopeptidase genes were identified as candidates to encode receptors of Cry proteins, which are toxins of Bacillus thuringiensis used to control lepidopteran pests. Since plantinsect interactions have produced a considerable number of adaptive responses in hosts and herbivorous insects, the success of phytophagous insects relies on their ability to overcome challenges such as the response to plant defences and the intake of nutrients. In this study, we identified metabolic pathways and specific genes involved in these processes. Thus, our data strongly contribute to the knowledge advancement of insect transcripts, which can be a source of target genes for pest management MenosThe sugarcane borer (Diatraea saccharalis, Fabricius, 1794) is a devastating pest that causes millions of dollars of losses each year to sugarcane producers by reducing sugar and ethanol yields.
