          Abstract

          Neste trabalho, estudaram-se o desenvolvimento e a reprodução de Dirphia moderata Bouvier, 1919 (Lepidoptera: Saturniidae) alimentada com Eucalyptus cloeziana F. Muell ou Psidium guajava L. Os períodos de pré-oviposição, oviposição e incubação e a viabilidade e número de ovos por fêmea foram de 6,71 ± 0,18 dia; 4,00 ± 0,66 dia; 18,14 ± 0,18 dia; 17,54 ± 3,78%; 121,71 ± 18,96% para esse inseto com E. cloeziana e de 3,86 ± 0,26 dia; 5,86 ± 0,40 dia; 17,71 ± 0,21 dia; 23,12 ± 10,81%; 112,00 ± 8,79% com P. guajava, respectivamente. A duração e viabilidade larval (%) foram de 53,00 ± 0,09 e 80,00 ± 0,99 e de 55,83 ± 0,29 e de 77,5 ± 6,60 para lagartas de D. moderata criadas nos primeiro e segundo hospedeiros, respectivamente. A duração e viabilidade das fases de pré-pupa e pupa foram de 4,84 ± 0,07 dia e 96,88 ± 3,13% e de 37,64 ± 1,20 dia e 84,37 ± 6,53% com E. cloeziana e de 3,82 ± 0,06 dia e 100% e de 49,93 ± 2,04 dias e 75,00 ± 7,79% com P. guajava, respectivamente. A razão sexual de D. moderata foi de 0,48 e 0,46 e a longevidade, de 6,78 e 8,84 dias para machos e de 10,23 e 10,07 dias para fêmeas desse inseto com E. cloeziana e P. guajava, respectivamente. D. moderata apresentou melhor desenvolvimento e reprodução em E. cloeziana, mas P. guajava pode, também, ser utilizado para a criação desse inseto em laboratório.

          This work studied the development and reproduction of Dirphia moderata Bouvier, 1919 (Lepidoptera: Saturniidae) fed on Eucalyptus cloeziana F. Muell or Psidium guajava L. The periods of pre-oviposition, oviposition and egg incubation as well as viability and number of eggs per female were 6.71 ± 0.18 days; 4.00 ± 0.66 days; 18.14 ± 0.18 days; 17.54 ± 3.78%; 121.71 ± 18.96 for this insect on E. cloeziana and 3.86 ± 0.26 days; 5.86 ± 0.40 days; 17.71 ± 0.21 days; 23.12 ± 10.81%; 112.00 ± 8.79 on P. guajava, respectively. Larva stage duration and viability (%) were 53.00 ± 0.09 and 80.00 ± 0.99 and 55.83 ± 0.29 and 77.5 ± 6.60 for caterpillars of D. moderata reared with the first and second hosts, respectively. Duration and viability of the pre-pupa and pupa stages were 4.84 ± 0.07 days and 96.88 ± 3.13% and 37.64 ± 1.20 days and 84.37 ± 6.53% on E. cloeziana and 3.82 ± 0.06 days and 100.00% and 49.93 ± 2.04 days and 75.00 ± 7.79% on P. guajava, respectively. Sex rate of D. moderata was 0.48 and 0.46 and longevity was 6.78 and 8.84 days for males and 10.23 and 10.07 days for females when this insect fed on E. cloeziana and P. guajava, respectively. Dirphia moderata presented better development and reproduction with E. cloeziana but P. guajava can also be used to rear this insect in the laboratory.

              Rearing of Thyrinteina arnobia (Lepidoptera: Geometridae) on guava and Eucalyptus in laboratory

              Thyrinteina arnobia, is one of the most important defoliating caterpillars of Eucalyptus in Brazil The objective of this work was to evaluate the development and the reproduction of feeding on leaves of guava (Psidium guajava) or Eucalyptus grandis in the 15th generation, after rearing this species for 14 genrations on guava leaves. T. arnobia showed shorter larval period, better viability of caterpillars and pupae, heavier pupae, higher number of eggs per female, better egg viability and shorter longevity of females in guava leaves than in Eucalyptus leaves. The better development and reproduction with P. guajava showed that this insect could be reared in laboratory with guava leaves.
