Última Attraction of Bucephalogonia xanthophis (Hemiptera: Cicadellidae) to volatiles of its natural host Vernonia condensata (Asteraceae) Scientia Agricola Bento,José Maurício Simões; Arab,Alberto; Zacarin,Giuliano Grici; Signoretti,André Gustavo Corrêa; Silva,José Wilson Pereira da. Plant volatiles are important cues for the orientation of herbivorous insects. It is possible that these compounds indicate whether the plant is suitable for feeding and larval development, or for mating aggregation. Vernonia condensata (Asteraceae) is known to attract species of leafhoppers, most of them important vectors of the citrus variegated chlorosis (CVC). In this study, we evaluated the role of volatiles of V. condensata on the orientation of Bucephalogonia xanthophis (Hemiptera: Cicadellidae). Four-arm olfactometer bioassays showed that only males were attracted to the volatiles of the host-plants Citrus sp. and V. condensata. Furthermore, fresh leaves of V. condensata induced a stronger response than volatiles from hexane-extracted leaves. This...

(Lepidoptera: Arctiidae) reared on artificial diet BABT Signoretti,André Gustavo Corrêa; Nava,Dori Edson; Bento,José Maurício Simões; Parra,José Roberto Postali. A study on the biology of Utetheisa ornatrix reared on the artificial diet, was conducted to determine the thermal requirements in each development stage. The aim was to find out the thermal regions in the São Paulo state where the pest could develop on Crotalaria spp. The insects were reared on an artificial diet based on the white beans and yeast. U. ornatrix thermal requirements were tested at 18, 20, 22, 25, 28, 30, and 32ºC 70±20% RH, and 14-h photophase. Lower threshold temperatures (TT) and thermal constants (K) for the egg, larval and pupal stages were 12.7ºC and 51.2 GDD, 13.5ºC and 290.9 GDD, 13.8ºC and 108.4 GDD, respectively; TT and K values for the biological cycle were 13.8ºC and 436.3 GDD.
