| The mode of action of Pochonia as a biological control agent is the penetration by means of the hyphae into the target nematode eggs. The egg shell of nematodes has an outer vitelline membrane composed mainly by proteins. Thus, hyphal penetration is the result of a physic pressure and the specific hydrolytic activity of some enzymes such as proteases and chitinases. The most important protease studied in Pochonia chlamydosporia var. chlamydosporia is VCP1. The aim of this work was to detect and characterize the protease VCP1 in a strain of P. chlamydosporia var. catenulata, a potential biological control agent for root-knot nematodes. The specific activity of this protease was tested on different culture media supplemented with protein inductors using... |

| Nematode assemblages associated to three species of lizards of the genus Mabuya Fitzinger, 1826 [M. agilis (Raddi, 1823), M. caissara Rebouças-spieker, 1974 and M. macrorhyncha Hoge, 1946] from three mainland sites and three island sites along the eastern Brazilian coast were analyzed. A total of six nematode species were recorded, with total nematode richness varying from one to four and overall nematode prevalences varying from 6.7% to 90.5% among host populations. Number of nematode species per host individual (including all hosts, infected and uninfected) varied among host populations from 0.07 to 1.05, but most infected lizards in all six host populations harbored a single nematode species. Both insular and continental populations of Mabuya spp.... |
