The treefrog Scinax camposseabrai (Bokermann) is endemic to the Brazilian semiarid region and known from the municipalities of Maracás, Igaporã and Curaçá, in the state of Bahia, and from the municipality of Matias Cardoso, northern Minas Gerais state, Brazil (Frost 2019). It was removed from the synonymy of Scinax x-signatus (Spix), recognized as a valid species, and placed in the S. ruber clade (sensu Faivovich et al. 2005) by Caramaschi & Cardoso (2006). Taxonomic changes proposed by Duellman et al. (2016) for the genus Scinax were discussed by Lourenço et al. (2016) and Faivovich et al. (2018), and we follow here their suggestion to consider Ololygon and Julianus (erected for the S. uruguayus group) as synonyms of Scinax. This large genus Scinax currently would include 123 species (Frost 2019), many of which have had their larval morphology formerly described. Here, we describe the external morphology of the previously unknown tadpoles of S. camposseabrai.

ABSTRACT The northern semiarid region of Minas Gerais is an important producer of irrigated Prata-Anã banana variety, which is highly susceptible to fusarium wilt. The organic cultivation of resistant varieties may be an phytosanitary alternative, also adding value to fruits. This study aimed to characterize banana varieties produced in organic system based on chemical and physical assessments at post-harvest. Prata-Anã, BRS Platina, Fhia-18, BRS Conquista and BRS Tropical varieties were characterized at the point of harvest (green) and mature (stage six of maturation), by chemical and physical assessments. At the point of harvest, BRS Conquista and BRS Tropical banana varieties had more intense green skin color. ‘BRS Conquista’ presented lower fresh weight, shorter length and diameter than the other varieties. BRS Platinum variety had more fruit fresh mass, length and diameter. Mature Prata-Anã, BRS Platina, Fhia-18, BRS Conquista and BRS Tropical banana varieties showed no difference in soluble solids, pH, titrable acidity and ratio; BRS Platina variety had more intense yellow skin color and lower pulp/skin ratio. Greater dropping resistance occurred in BRS Conquista variety and BRS Tropical was less resistant. Prata-Anã banana variety showed higher firmness. Banana varieties differed more by the physical characteristics (skin color, size, dropping resistance, firmness and pulp/skin ratio) in relation to chemical characteristics.

Abstract Anthracnose stands out among rot diseases that can occur in the post-harvest phase of banana. The aim of this study was to evaluate the thermotherapy in the control of anthracnose in ‘Prata Anã’ banana produced in northern state of Minas Gerais. Bananas ‘Prata Anã’ variety were divided into groups of three fruits and inoculated with Colletotrichum musae. Groups were submitted to thermotherapy using five temperatures (40°C, 44°C, 48°C, 52°C and 56°C) and four immersion times (4, 8, 12 and 16 minutes) and control. Treatments were repeated five times in a completely randomized design. Area under the incidence progress curve (AUIPC) and area under the severity progress curve (AUSPC) were calculated. To evaluate the thermotherapy efficiency compared to chemical control, fruits were submitted to the following treatments: thermotherapy with and without fungicide application and fruits treated with fungicide only, the control fruits without thermotherapy and without fungicide application. After fifteen days of storage, fruits were evaluated for anthracnose severity. The results of experiments were submitted to analysis of variance and regression and means were compared by the Scott-Knott test (p<0.05). Control was compared to treatments by the Dunnett test (p<0,05). The lowest anthracnose AUIPC values were observed when using temperature of 48°C for eight and 12 minutes. Thermotherapy at 52°C from eight minutes of immersion, in addition to reducing the anthracnose AUSPC in fruits up to 81.6%, delayed maturation of fruits. Fruits submitted to thermotherapy at 56°C presented higher severity of the disease and resulted in the maturation of fruits. Thermotherapy reduces anthracnose severity in fruits in a manner similar to fungicide use, but the association of both results in better control of the disease in ‘Prata Anã’ banana. Thermotherapy is an efficient technique to reduce the severity of the disease in ‘Prata Anã’ banana produced in northern state of Minas Gerais.

ABSTRACT This paper aimed to evaluate the occurrence of Gonodonta larvae defoliating sugar apple (Annona squamosa) and atemoya fruits (Annona squamosa x Annona cherimolia L. Mill.) in northern state of Minas Gerais. Larvae were collected between December 2007 and January 2008 in Annonaceae plantation in the rural area of the municipality of Janaúba, MG. Adults obtained have been sent for identification. The species identified were Gonodonta bidens Geyer, G. nutrix Stoll and G. pyrgo Cramer. The infestation level observed in the orchard was 85% of plants with the presence of Gonodonta larvae and the average defoliation percentage was 30%. These are the first records of Gonodonta species defoliating sugar apple and atemoya in Brazil.

The objective of the present study was to evaluate the productive performance and nutritional value of forage of wheat and triticale cultivars at different harvest times in the semiarid region of Minas Gerais. Eight wheat cultivars and two triticale cultivars harvested at three stages of plant development were evaluated: Rubberization, grain at the stage of soft mass and harvest maturation. The experimental design adopted was a randomized block in a factorial scheme 10 × 3, with three replicates, 10 cultivars and 3 developmental stages for plant collection. The main agronomic characteristics and nutritional value were evaluated of forage of the cultivars under study. The study demonstrated the potential of wheat and triticale cultivation for forage in the semiarid region of Minas Gerais. The mean dry matter yield of wheat cultivars was 5.90 t ha-1, 7.85 t ha-1 and 7.98 t ha-1 and triticale 6.47 t ha-1, 9.97 t ha-1 and 10.5 t ha-1 for the rubber harvesting stages, grain at the stage of soft mass and harvest maturation, respectively. For the average crude protein content, the wheat cultivars showed 15.07%, 9.13%, 10.60% and the triticale cultivars showed 14.4%, 9.31% and 10.05% for the harvest stages of rubber formation, grain at the stage of soft mass and harvest maturation, respectively. When evaluating the average levels of total digestible nutrients, the wheat and triticale cultivars showed an average of 48.90% and 48.67% in the rubber harvesting stage and 42.68% and 49.60% in the grain in the mass stage suave and 44.43% and 42.90% at harvest maturation. The highest yield of digestible dry matter was observed with the cultivars harvested at the grain stage at the soft mass stage. Triticale IPR 111 and Wheat IPR PANATY had greater productive potential and better nutritional quality for use as forage.
