Here we describe the life histories of adult males of the the Amazonian stingless bee Melipona flavolineata Friese, commonly known as ?uruçu amarela?. Males reach sexual maturity inside nests, presenting seminal vesicles full of sperm cells and becoming able to fl y at a mean age of 10 and 15 days, respectively. They aggregate twice in their lives, once before leaving the nest, and another at external congregation sites, by using their capacity to reach congregation sites dependent on morphological attributes, such as large eyes and elongated thorax. Furthermore, we describe three atypical phenomena for Meliponini males: M. fl avolineata males have dimorphic color pattern; they lose their genital capsules, even when they fail to copulate; and penisless (sterile) males can stay alive for up to two days. The life history strategies of Meliponini males have only just started to be told and provide many interesting questions for future studies. |

The proper nitrogen management is required to achieve high irrigated rice yield. This study aimed to determine the rice response to nitrogen topdressing doses and calibrate the chlorophyll meter reading. Three experiments were conducted in a randomized block design. In the first experiment, five N rates (0, 30, 60, 90, and 120 kg ha-1) were evaluated as the first, and 30 kg ha-1 N as the second topdressing, which were combined with the application of 30 kg ha-1 N as the first and five N rates, as the second topdressing. The other experiments assessed the application of 30 kg ha-1 of N, as the first, and four N rates (0, 40, 80, and 120 kg ha-1), as the second topdressing. There was a response to N application, with maximum technical efficiency reaching 33 kg ha-1 in the first and between 40 and 50 kg ha-1 in the second topdressing. The chlorophyll meter was sensitive to estimate the amount of N to be applied in topdressing, using the nitrogen sufficiency index (NSI). To each percent unit of NSI below 95%, one should apply 10 kg ha-1 of N as the first and 2-3 kg ha-1 of N as the second topdressing. |
