In this study, patterns of spatial synchrony in population fluctuations (cross-correlation) of an endemic fish assemblage of a Neotropical reservoir (Segredo Reservoir, Iguaçu River, Paraná State, Brazil) were reported. First, the level of population synchrony for 20 species was estimated. Second, population synchrony was correlated, using the Mantel test, with geographical distances among sites (n = 11) and also environmental synchrony (temperature). Nine species presented significant correlations between spatial synchrony and geographic distances (Astyanax sp. b, Astyanax sp. c, Pimelodus sp., Hoplias malabaricus, Crenicichla iguassuensis, Hypostomus derbyi, Hypostomus myersi, Rhamdia branneri, and R. voulezi). Considering the ecology of the species and the significant relationship between population and environmental synchronies, it seems that environmental stochasticity is the most plausible hypothesis in explaining the observed synchrony patterns.

Burnt pine longhorn (BPL) Arhopalus ferus (Mulsant) (Coleoptera Cerambycidae) is an introduced species sometimes found in association with export logs and sawn timber A rearing method was developed to produce larvae of a known age number and quality for control trials Growth of larvae from newly hatched to 5 weeks was measured on a standard cerambycid artificial diet and on modified diets Replacing pine wood with pine bark sawdust increased survival at 5 weeks from 23 to 76 and mean weight from 9 to 21 mg There were significant interactions between the influences of three factors (diet period of rearing initial larval density) on the weight of surviving larvae Individual rearing was preferred for convenience and a standardised method was used to rear 8740 larvae for disinfestation trials Establishment and survival to 6 weeks for these larvae was 97
