A total of 25 aphid species were collected from 49 ornamental plant species in S?o Carlos-S?o Paulo, Brazil; 12 aphids were monophagous, four oligophagous and nine polyphagous. A total of 58 aphid-plant associations are recorded, 43 unknown from Brazil. Eucarazzia elegans (Ferrari, 1872) (Aphididae: Aphidinae: Macrosiphini) is recorded for the first time from Brazil, and Nectandra megapotamica Spreng. (Lauraceae) is recorded for the first time as host plant for Lizerius tuberculatus (E.E. Blanchard, 1939) (Drepanosiphidae: Drepanosiphinae: Lizeriini). We also describe the injuries caused by aphids to the ornamental plants. 相似文献

Riassunto Nell'ambito del progetto «Flora Palinologica Italiana» e proseguendo lo studio delle Corylaceae, è qui presentata la scheda diCarpinus betulus L., con alcune osservazioni sul numero/posizione delle aperture e sulle principali differenze tra polline «fresco» e polline acetolizzato.
Summary According to the program «Palynological Italian Flora», and continuing the study of the Italian Corylaceae, the palynological card ofCarpinus betulus L. is shown. The study is carried out on pollen coming from three different localities and regards both «fresh» and acetolyzed pollen. For each sample, measurements are carried out on 30 «fresh» pollen grains in glicerol jelly and on 30 acetolyzed pollen grains in water/glicerol 1/1; general observations regard 500 «fresh» and 500 acetolyzed pollen grain/sample. Some morphological observations on the aperture number/position and differencies between «fresh» and acetolized pollen are pointed out.相似文献

Seeking to identify thrips species associated to peach and the injuries they cause, plants of Aurora and Tropic Beauty cultivars were weekly monitored, from May to August of 2005, in Holambra II district, in Paranapanema, SP. Flowers and fruits from six plants per hectare were sampled by the hitting technique. Frankliniella occidentalis (Pergande), F. schultzei (Trybom), F. gardenia (Moulton), F. condei John, F. insularis (Franklin) and Thrips tabaci Lindeman, in Thripidae, and Haplothrips gowdeyi (Franklin), in Phlaeothripidae were identified. F. occidentalis was dominant, comprising 55.7% of the total specimens sampled. Slight and severe injuries were registered in fruits. 相似文献
