Sampling study of spittlebug eggs in pastures of Brachiaria decumbens was conducted by using a sample unit of 15 x 15 cm. The number of samples required for a certain level of precicion was inversely proportional to population density. A crude estimate of number os samples necessary for 10, 15 and 20% of precision were 133,59 and 33, respectively. A study of sampling variation showed that differences between plots were much more important than the block differences; therefore plot to plot variation must be considered wwhile sampling spittlebug eggs. The distribution pattern of numbers of eggs per 225cm2 of pasture fitted the negative binomial series. The sequential sampling plan presented here would reduce the sampling time over the conventional (fixed sample numbers) sampling. |

The chemical composition of the essential oil from the leaves and flowers of Lippia stachyoides var. martiana (Verbenaceae) from the Brazilian Cerrado was analyzed by GC/FID and GC/MS. Fifty-seven and forty-one essential oil constituents were identified in the flowers and leaves, respectively, being thirty-eight substances found in both oils. Flowers and leaves essential oils were rich in (E)-nerolidol (15.6 and 16.4%), ?-cadinene (15.8 and 18.5%), spathulenol (8.1 and 16.4%), caryophyllene oxide (6.6 and 7.8%) and cubebol (8.5 and 7.4%), respectively. Both essential oils also showed promising results against yeast-like fungi and bacteria. Good antifungal activity was observed for Cryptococcus neoformans, with MIC?s of 156 ?g/ml and 78 ?g/ml for flowers and leaves oils, respectively. |
