In Brazil, the species Diatraea flavipennella and D. saccharalis play an important role in the sugar and alcohol agribusiness by causing many damages in sugarcane fields. The egg, larva, pupa, and adult stages are very morphologically similar between these species, and the identification can be confused. The internal transcribed spacer 2 (ITS 2) from ribosomal DNA has important features as evol.. Read More»

Plague outbreaks are occasionally reported in Brazil. Unfortunately, due to great genetic similarity, molecular subtyping of Yersinia pestis strains is difficult. Analysis of multiple-locus variable number of tandem repeats (VNTR), also known as MLVA, has been found to be a valuable tool to discriminate among strains. To check for genetic differences, strains obtained from two different ecologi.. Read More»

Aedes aegypti and A. albopictus represent the two most important species of mosquitoes in relation to dengue virus transmission both in the Americas and Asia. However, the study of theses species generally requires the establishment of a colony for the larvae to hatch, or waiting for the adult development to perform its taxonomic classification, which is time consuming. Thus, the establishment .. Read More»
