This study was made in an urban forest fragment in Campo Grande, Mato Grosso do Sul State, Midwest of Brazil. During a three year period, from 2012 to 2015, the presence of tick species in the environment (vegetation and soil), their seasonality and the occurrence of rickettsial infection in ticks was investigated. 1219 samples were collected, from which 1045 belonged to the Amblyomma sculptum species and 174 belonged to the Amblyomma dubitatum species. The A. sculptum species presented its main annual peak in the periods when rainfall and temperature were the highest, while the A. dubitatum species presented a higher population level in the following season. However, the A. sculptum population decreased during the second year of the study, probably due to the installation of a physical barrier by the end of the first year, what has possibly caused a momentary decrease in the circulation of the ectoparasites? hosts. The A. dubitatum population remained stable. All sampled ticks presented a negative result regarding rickettsia DNA detection using the polymerase chain reaction method. |

The objective of this work was to set up ideal conditions for conidia mass production of Dicyma pulvinata. Four isolates were compared in terms of their growth and conidia production on various substrates (grains of parboiled rice, common rice, maize and wheat, besides chipped maize and rice husk), temperatures (19, 22, 25, 28 and 31oC), growth containers (aluminum trays, polypropylene bags and Erlenmeyers) and light regimes (continuous darkness, 6 and 12 hours of light/darkness, and continuous light). Temperature effects on conidia germination capacity were also evaluated. The experiments were done in randomized complete block designs, in factorial arrangements (isolates x treatments ? substrates, containers, temperatures and light regimes), with four replicates. In general, parboiled rice and polypropylene bags provided the best development of the fungus. Complete darkness and 6 hours of light increased mycelial growth, whereas continuous light favored sporulation. All tested temperatures favored the cultures of the fungus, except 31oC. Temperatures between 19 and 25oC ensure spore germination of more than 76%. |
