| In most northwest provinces of Iran such as West Azarbaijan province, soil salinity is a growing problem, particularly in irrigated agricultural areas, and has been found to reduce barley yield, dramatically. To investigate the effect of sodium chloride on two barley (Hordeum vulgare) cultivars, four levels of salinity: 0, 4, 8 and 12 dS/m, were employed as a factorial experiment arranged in a completely randomized design with three replications in a controlled environment of the greenhouse during 2017-2018. The results indicated that increasing salinity from 0 to 12 dS/m, decreased the emergence percentage significantly. Two cultivars of Zarjoo and Valfajr responded differently to salinity, so that Zarjoo showed a significantly higher emergence rate. This... |

| Abstract The study investigated native solitary bee species that nest in pre-existing cavities in the Baturité Massif, State of Ceará, Brazil, their preference for nest substrates and aspects of these bee communities. Samples were taken in four distinct areas of the Baturité Massif using three types of trap-nests: dried bamboo internodes, cardboard tubes and rational boxes. Out of the 185 nests offered, 34 were colonized and 24 of them produced 131 bees, belonging to two families (Apidae and Megachilidae) and five genera (Centris, Mesocheira, Euglossa, Megachile and Coelioxys) from six species, including parasitic ones. Nesting preference was observed to certain types of substrates (χ²=17.89, p<0.001), with bamboo internodes being preferred by bee to... |

| Adult emergence and mating behavior of Neoleucinodes elegantalis Guenée were studied under laboratory conditions (23 ± 1°C, 12 h photophase and 70% RH). Adult emergence occurred only at scotophase period. Female began to emerge from the 1st hour to 8th hour with a peak occurring at 4th hour of scotophase. Male showed similar trend, but emerging from 2nd to 11th with a peak also at 4th hour of scotophase. Mating was preceded by wing vibration in the male prior to and during walking approach. Mating occurred only during the scotophase period between the 4th and 10th hour of scotophase, with the peak occurring at the 7th hour. Newly emerged N. elegantalis couples rarely mated (2.8%) whereas 48 and 96 h old couples mated 26.3% and 27.5% respectively. Glands... |

| RESUMO: O objetivo deste trabalho foi avaliar os efeitos do tempo de imersão e da concentração de ácido giberélico na quebra de dormência das sementes de diferentes matrizes de pequi. Consistiu em dois experimentos conduzidos em safras distintas: no primeiro, os caroços oriundos da mistura de várias plantas foram submetidos à imersão por dois e quatro dias, em três concentrações de GA3 (0,500 e 1000 mg.dm³). O delineamento experimental foi inteiramente ao acaso, com oito repetições de 50 sementes por parcela, em esquema fatorial 3x2, mais a testemunha constituída de caroços não tratados. O segundo foi conduzido na safra seguinte, sendo os caroços colhidos e mantidos separados por planta-matriz (sete ao todo) e submetidos à imersão por dois e quatro dias em... |
