| Thermal hygrometric requirements for the rearing and release of Tamarixia radiata (Waterston) (Hymenoptera, Eulophidae). Tamarixia radiata is the main agent for the biological control of Diaphorina citri in Brazil with a parasitism rate ranging from 20 to 80%. This study investigated the influence of temperature on the development, fecundity and longevity of adults of T. radiata and the effect of relative humidity (RH) on their parasitism capacity and survival rate in the pre-imaginal period. The effect of temperature was assessed in the range between 15 and 35 ± 1ºC, 70 ± 10% RH, and a 14-h photophase. The RH effect was evaluated in the range from 30 to 90 ± 10%, temperature at 25 ± 1ºC, and photophase of 14-h. At 25ºC, circa 166.7 nymphs were... |

| Influence of temperature on longevity, fecundity, and haematophagic activity of Aedes (Stegomyia) albopictus Skuse, 1894 (Diptera, Culicidae) under laboratory condition. Based on adults of Aedes albopictus maintained under four constant temperatures, 15ºC, 20ºC, 25ºC and 30ºC, longevity of males and females, fecundity, eggs viability, number of days from emergence to the first bloodsucking, and duration of the preoviposition period were observed. The average of the longevity for female was 19.45, 59.35, 61.55 and 42.72 days, under 15ºC, 20ºC, 25ºC and 30ºC, respectively. The greatest average number of bloodsucking per female was 8.32, under 25ºC. The average number of eggs per female was 1.00, 73.91, 269.87 and 183.69, and the greatest rates of viable eggs... |

| Abstract Borellia bruneri, a common grasshopper in much of the grasslands of Argentina and Uruguay, is considered, according to the categories widely accepted for defining the pest status of grasshopper species, a “Frequent plague of importance”. In order to determine fundamental aspects of its biology and reproduction, three cohorts of B. bruneri were monitored under controlled conditions (30º C, 14L: 10D, 40% RH). The total duration of nymphal development was 50.6 days, both males and females having five nymphal instars. There was a significant difference in the duration of the different stages within each cohort. In the three cohorts, the first instar duration (12.87 days) was longer than the rest, approximately 5.6 days more than the second that was... |

| Gliricidia sepium is a drought-tolerant species, easily multiplied by seeds, and has been exploited by farmers as a source of forage in the semi-arid region of northeast Brazil. The objective of the present study was to evaluate the effect of seed storage on the mobilization of reserves during imbibition of "Gliricidia" seeds. Freshly-harvested seeds were packed in kraft paper bags and stored for three and six months in the laboratory under ambient conditions (25 º C ± 3 T and 75% ± 3 RH). Cotyledons were isolated from imbibed seeds and macerated for the extraction and quantification of total soluble sugars, reducing sugars, sucrose and starch, as well as of proteins, amino acids and for amylase activity. Storage under these conditions resulted in an... |

| ABSTRACT This study aimed to estimate the growth and size at the onset of sexual maturity in a population of Aegla georginae . Specimens were sampled from November 2007 to October 2008 in the Perau Creek (Ibicuí-Mirim sub-basin; Uruguay River basin). All captured specimens were sexed, and their cephalothoracic length (CL), minor and larger propodi length (MPL, LPL, respectively), height of major chela (HMQ), and abdomen width (AW) were measured. The lengthwise growth of males and females was evaluated using the Bertalanffy model, and the morphological sexual maturity was evaluated using the REGRANS program. The smallest ovigerous female presented a 10.45 mm CL. Males reached larger sizes than did females, but the growth rate was similar between the sexes.... |

| ABSTRACT In commercial cultivation of sugarcane, knowledge about the repetition of agroindustrial characters is essential to identify long-lived genotypes in production cycles, which when selected, will contribute to the significant increase in productivity. This work evaluated the agroindustrial performance of 16 sugarcane genotypes in the sugarcane microregion Litoral Norte of Pernambuco in four harvest cycles and the regularity in the repetition of characters. The experiment was conducted in the agricultural area of São José sugar mill, Igarassu, state of Pernambuco, Brazil. The experiment was carried out following a randomized block design with four replications. The variables evaluated were: tons of POL per hectare (TPH), tons of cane per hectare... |

| Aimed to evaluate the coat and Quarter reproductive age used in equine production used in Vaquejada in micro regions of the Northeast. They used information from 264 horses, taken from the database of the Association of Quarter Horse Breeders (ABQM). Were collected individual information: date of birth, sex and animal fur, number of copies of disputed official Vaquejada, better and worse placed, cumulative score in ABQM, coats and dates of parents' birth (31), coats and birth dates mothers (257). There was a higher frequency (P<0.05) of births between the months of September and October. There was no age-specific greater use of stallions or matrix playback (P>0.05). There was no correlation (P>0.05) between the number of children and the stallion... |

| Cyrtomon luridus (Boheman) has adapted to the medicinal plant Duboisia sp., introduced from Australia. Its larvae feed on roots, causing up to 100% mortality damages. The population dynamics and biological cycle were studied to determine future control methods in Duboisia sp., in Arapongas, Paraná State, Brazil, from 1993 to 1996. C. luridus presented annual life cycle in Duboisia sp. under natural conditions. The larval development period was 120 to 150 days, from January to May, reaching an average size of 19.0 ± 2.0 mm in soil depth ranging on 24.9 ± 8.6 cm to 45.0 ± 10.0 cm. The beginning of the pupal phase happened in April. The larval-adult viability ranged on 7.5% to 19.6%. The typical symptoms of attack appeared in an infestation level of 60 larvae... |

| Present study was conducted to evaluate RD14 seed accelerated aging for longevity in humid tropic at Phrae Rice Research Center. Rice seeds from wet season, 2012 were stored in plastic bags at room temperature and were monitored for seed quality every month. Moreover, the rice seed samples were aliquoted for Accelerated Againg Test (AA) with 100% relative humidity and the temperature condition was varied from 44 46 and 48 0c for 72 96 120 and 144 hrs, respectively. The results revealed the correlation between seed germination from each temperature and time accelerated aging and seed stored in plastic bags at room temperature. It was shown that RD14 seed at moisture content 13% in plastic bag could be stored for 6 months with more than 80 % germination.... |

| Abstract Jambu (Acmella oleracea [(L.) RK Jansen]) is a vegetable of great importance in the Amazonian region; it can be found in the daily life of the citizens of the State of Pará (Brazil), since it is part of traditional dishes such as duck in tucupi and tacacá sauce. Although jambu is widely cultivated, agronomic information about its management remains scarce. The aim of the current study was to analyze the physiological potential of jambu seeds stored in different packages and environments. The investigated packages comprised glass, Eppendorf tubes, plastic bags and paper bags conditioned in refrigerator and under natural conditions in Castanhal, Pará, for 360 days. Seed germination, first germination count, emergence seedlings, germination and... |

| Abstract Conflicting responses have been found for the period of conservation of passion fruit seeds. Therefore, this study aimed to evaluate the response of the seeds of passion fruit progenies to a 24-month storage period. The sour passion fruit progenies from the third cycle of Universidade Estadual do Norte Fluminense Darcy Ribeiro - UENF intrapopulation recurrent selection program were grown in Itaocara- RJ and the progenies seeds were evaluated for: germination potential, germination first count, accelerated aging, first count of accelerated aging test, seedling and radicle size and germination speed index. The germination and vigor of the seeds of the full-sib progenies were assessed by analysis of variance and factorial arrangement with 3 progenies... |
