“…1). Responses of males in the olfactometer were similar to those observed for Phyllocnistis citrella (Gracillariidae) (Parra et al, 2002;Parra-Pedrazzoli et al, 2006) and suggested that the gland extracts elicit sexual attraction of males.…”

The sex pheromone of Lonomia obliqua Walker (Lepidoptera: Saturniidae) was studied in the laboratory. All female calling occurred during the scotophase. Most females (70.6%) called first within 24 hr of eclosion. Calling varied with age of female, with older (5-to 6-day-old) females calling earlier in the scotophase and for longer durations than younger (0-to 1-day-old) females. The sex pheromone gland of 1-to 3-day-old virgin females was extracted during the calling peak. A Y-olfactometer bioassay showed significant attraction of males to a filter paper containing the female gland extract. Gas chromatographic-electroantennogram detection (GC-EAD) analysis of the extract indicated the presence of at least two possible pheromone components. Gas chromatographic-mass spectrometric analysis of the major GC-EAD-active peak indicated a hexadecenyl acetate; chemical derivatization indicated Δ11 unsaturation. Synthetic samples of (E)-and (Z)-11-hexadecenyl acetate were obtained by coupling 10-bromo-1-decanol and 1-hexyne, utilizing lithium chemistry. The comparison of the retention time of dimethyl disulfide derivatives of the natural compound, to those of synthetic chemicals, confirmed the natural compound as (E)-11-hexadecenyl acetate. The minor component was identified as the related alcohol, (E)-11-hexadecenol. The ratio of the two components in female extract was 100:35. Preliminary tests of males in a Y-olfactometer showed that their response to a mixture of the two compounds was not significantly different from that to gland extract.

“…Esses fatores podem ter infl uenciado o tamanho dos brotos oferecidos para o minador-dos-citros, visto que mudas maiores apresentam brotação mais vigorosa e, conseqüentemente, folhas de maior tamanho, podendo propiciar maior abundância de recursos para o desenvolvimento da praga (Heppner 1993). Segundo Godfray (1994) e Parra et al (2002), a maior quantidade de recursos oferecidos pelas plantas onde os hospedeiros se desenvolvem, pode resultar em menor mortalidade das fases imaturas dos parasitóides.…”

“…Avaliaram-se a duração e a sobrevivência das fases imaturas, a longevidade, a razão sexual, as taxas de oviposição e a atividade de predação dos adultos. Segundo Parra et al (2002), esses aspectos são importantes na avaliação da qualidade do parasitóide criado em laboratório em comparação com os que ocorrem na natureza.…”

-The biology of Cirrospilus neotropicus Diez & Fidalgo reared on third instar Phyllocnistis citrella Stainton larvae having Citrus limonia Osbeck as host plant, was evaluated under controlled conditions (25 ± 1ºC; 12h photophase). The survival, immatures development, longevity, sex ratio, host feeding and oviposition ratio of C. neotropicus, were registered. Two groups of parasitoid females were evaluated: one, with parasitoids obtained from P. citrella pupae collected in citrus orchards and the other group came from laboratory rearing. These females, after mating, were maintained individually on gerbox containers with honey and pollen as food source. At each 48h, 12 P. citrella larvae were changed. The average biological cycle of the female progenies from orchard and laboratory generation groups were 11.8 and 11.6 days, respectively. The males progenies had biological cycles of 11.6 and 10.9 days, as well. The shortest immature survival period, for both studied groups was the larval (57.3% -orchard group and 57.4% -lab group). The mated females average longevity (21.8 days) was superior than the non mated ones (9.1 days) for the orchard group. The average daily oviposition rate for this last group was also signifi cantly superior (2.8 eggs /day) than the lab group (1.6 eggs / day). The same trend was observed for the average daily host feeding rate (1.7 larvae /day for the orchard group and 0.9 larvae/ day for the lab group). These data suggest that C. neotropicus have potencial as a biological control agent of P. citrella.

“…Os adultos emergem ao amanhecer, e realizam suas atividades do crepúsculo ao amanhecer (ALBA, 1996;RÖSSLER, 1996;GARIJO;GARCIA, 1994;HEPPNER, 1993). A oviposição de P. citrella é realizada durante o crepúsculo (BADAWY, 1967;HEPPNER, 1993;PANDEY;PANDEY, 1964;VILELA;BENTO, 2002). A cópula inicia-se dentro de um período máximo de 9 a 72 h após a emergência, com duração variável de 30 min até 9 h (BA-ANGOOD, 1977;BATRA et al, 1988;CLAUSEN, 1931;HUANG et al,1989a;RADKE KANDALKAR, 1987;PANDEY;PANDEY, 1964;KNAPP et al,1994).…”
