New reports on parasitism by Haplometroides buccicola (Digenea, Plagiorchiidae) in Brazilian snakes

The occurrence of Haplometroides buccicola (Digenea, Plagiorchiidae) in the esophagus of two Brazilian snakes is reported in the present study. The trematodes were collected from one Micrurus corallinus (Elapidae) and one Phalotris lativittatus (Colubridae); both snakes were found in Botucatu city, São Paulo State, Brazil. Morphological and morphometric analyses of the trematodes are presented. For the first time Micrurus corallinus has been recorded as a host for H. buccicola and this is the second time that P. lativittatus has been reported as a host for this trematode species.

Hymenoptera marking technique

In true social hymenopterans, such as many species of bees, wasps and all species of ants, the main characteristics are the overlapping of generations, the care with the offspring and the division of labor among the members of the colony. The first biological feature means that in a same moment there are groups of individuals, with variable ages, that execute different activities in the colony. In order to study the division of labor among the members of the colony, or to estimate the life span of these insects, or even to analyze any kind of behavior in non-social insects, it is necessary to know the exact age of each individual. For this reason, the insects must be identified soon after emergence. The identification of insects with numbers is an important technological improvement in behavioral studies, mainly in honeybee colonies. The aim of this scientific note is to describe an easy and cheaper technique for marking hymenopterans.

Detection and partial characterization of a carlavirus causing stem necrosis of soybean in Brazil

No ano agrícola de 2000/2001, ocorreu um surto de nanismo e necrose da haste em soja (Glycine max) plantada em duas áreas do Brasil Central e na safra seguinte, esta anomalia foi constatada em outras regiões produtoras, mesmo distantes mais de 2.000 km de onde fora inicialmente constatada. Estudos envolvendo ensaios de transmissão (enxertia, mecânica e insetos vetores), microscopia eletrônica, purificação, sorologia e ensaios moleculares indicaram que a enfermidade foi causada por um carlavirus transmitido por mosca branca, possivelmente relacionado ao Cowpea mild mottle virus (CpMMV).
