| Forty six beetles Scotocryptus melitophilus Reitter, 1881 collected in a nest of Melipona quadrifasciata Lepeletier, 1836 were studied. All beetles were put together in a large petri dish with 14 males, 14 virgin queens and 14 workers of M. quadrifasciata, which was not aggressive towards the S. melitophilus and flew with 3 to 10 beetles attached to them. When groups of 20 workers, 20 males and 20 virgin queens were put separately in three petri dishes, the workers become attractive to beetles after they were seven days old, while the males after the 19 days old. Only one virgin queen five days old attracted one beetle. The anatomic parts of the workers bees more attractive to the beetles when smeared to a filter paper were the head (32%), abdomen (29%)... |

| Commensalism between Corydalus Latreille, 1802 (Megaloptera, Corydalidae) and Corynoneura Winnertz, 1846 (Diptera, Chironomidae, Orthocladiinae) larvae was recorded in Indaiá stream, at 1,380 m a.s.l. (Parque Nacional da Serra do Cipó, 19º-20ºS, 43º-44ºW) and in the headwaters of São Francisco river, at 1,300-1,700 m a.s.l. (Parque Nacional da Serra da Canastra, 20º00'-20º30'S, 46º15'-47º00'W), in Minas Gerais state, Brazil. Seventy eight Corydalus larvae (range 22-88 mm) were sampled: 61 in the Indaiá stream and 17 in other two streams. Twelve Corydalus larvae (22-79 mm) in the Indaiá stream and three out of 15 larvae in the headwaters of São Francisco river (38-50 mm) had Corynoneura, larvae and pupae on their gills (3rd to 6th) and a few larvae attached... |

| Dung beetles (Coleoptera: Scarabaeidae: Scarabaeinae) compete intensively for dung resources, and most species forage in the understory. Here, we describe the unique behavior of one dung beetle species, Canthon aff. quadriguttatus (Olivier), associated with two species of monkeys from Peru. We observed this beetle species on the genital and anal regions of the brown titi monkey, Callicebus brunneus (Wagner), and subsequently falling with dung as the monkeys defecated. The same association was also observed with the bald-faced saki monkey, Pithecia irrorata irrorata (Gray). Using the " sit and wait" at the source behavior, C. quadriguttus may arrive first at the dung resource, possibly out-competing other dung beetle species. This paper is the first report... |

| De huertas comerciales de mango de Guerrero y Michoacán, México, se colectaron trips por muestreo aleatorio de árboles para identificación de especies, determinar su relación forética con Fusarium spp., transmisión de estos hongos, agentes causales de malformación vegetativa y floral de mango, y fundación de colonias de trips en condiciones asépticas en cámaras bioclimáticas. Se obtuvieron ejemplares de trips pertenecientes a dos géneros y 11 especies, siete pertenecientes a Scirtothrips y cuatro a Frankliniella. Los trips fueron recolectados detejidos vegetativos y florales, asintomáticos o malformados. Se reporta por primera vez a F. difficilis, F. occidentalis, F. gardeniae, F. minor, S. bisbravoae y S. silvicola asociados al cultivo de mango en... |

| En el presente trabajo se documentaron y describieron los diferentes aspectos de la taxonomía, biología y ecología de los ácaros asociados a escolitinos de importancia forestal en nuestro país. El objetivo principal fue el de conocer su diversidad, abundancia, distribución, estructura poblacional, así como conocer diferentes aspectos de las relaciones que presentan con otros microorganismos en el mismo microecosistema. Para ello se realizaron muestreos desde 2008 hasta el 2012, en los cuales se tomaron muestras de corteza y raíces con signos de daño por los descortezadores. Como complemento se revisaron colecciones acarológicas de diferentes instituciones, así como colecciones de descortezadores preservadas en alcohol. De acuerdo a la información obtenida... |
