Abstract

DESENVOLVIMENTO E REPRODUÇÃO DE DEVELOPMENT AND REPRODUCTION OF Dirphia moderata (LEPIDOPTERA: SATURNIIDAE) ON Eucalyptus cloeziana OR Psidium guajava LEAVES UNDER LABORATORY CONDITIONS ABSTRACT -This work studied the development and reproduction of Dirphia moderata 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

Biology and External Morphology of the Immature Stages of Dirphia moderata Bouvier (Lepidoptera: Saturniidae: Hemileucinae) in Anacardium occidentale L.

“…The first studies on the duration of the immature stages of D. moderata (Dias, 1988;Zanuncio et al, 1994;Pereira et al, 2008a, b) recorded cycles with an average of 90-130 days for a complete development of immature stages, which corresponds to approximately 3.5 generations per year, and this same pattern was corroborated in this study for D. moderata in the municipality of Cruz das Almas, as previously determined for other species of the genus recorded in the literature, such as Dirphia araucariae Jones, 1908, and Dirphia dolosa Bouvier, 1929(Specht et al, 2012Zenker et al, 2013), with the same proportion of days of each stage and larval instars, except for pre-pupae and pupa, which may vary according to the host plant, as observed by Pereira et al (2008b). This pattern of ontogeny of the immature stages has also been recorded for other genera of Hemileucinae, such as Lonomia Walker, 1855, Automeris Hübner [1819], and Periga Walker, 1855, specially for hot climates, characterizing such genera as multivoltine (Lorini, 1999;Specht et al, 2006bSpecht et al, , 2007bSpecht et al, , 2011.…”

“…In the laboratory, fed with cashew leaves, this stage lasted between 54-65 days. Zanuncio et al (1994), breeding D. moderata on E. urophylla leaves, and Pereira et al (2008b) breeding it on P. guajava leaves obtained 50 days. However, by feeding larvae with E. cloeziana leaves, a lower number was found (37 days), close to the results obtained by Santos et al (2011) on leaves of S. mombin.…”

Aspects of the biology and morphology of Dirphia dolosa Bouvier, 1929 (Lepidoptera: Saturniidae: Hemileucinae)

“…Among them are some species known to be polyphagous: D. avia Stoll, 1780 (Silva et al 1968, Janzen & Hallwachs 2009), D. horcana Schaus, 1911(Janzen & Hallwachs 2009, D. moderata (Dias 1988, Zanuncio et al 1994, Pereira et al 2008; or oligophagous, with larvae found feeding exclusively on Myrsinaceae such as D. baroma (Schaus, 1906) (Specht et al 2008) and Dirphia monticola Zerny, 1924(Zikán, 1927. Besides these, Callodirphia arpi (Schaus, 1908), whose larvae also only feed on Myrsinaceae (Zikán 1927), is worth mentioning.…”

Biological and morphometric aspects and rearing of Syssphinx molina (Cramer) (Lepidoptera: Saturniidae), a defoliator of parica tree

“…There is variation in the life cycle of adults of other Saturniidae when fed with alternative diet as seen in Dirphia moderata Bouvier, whose males lasted 8.84 and 6.78 days and the females, 10.23 and 10.07 days when fed on leaves of Eucalyptus cloeziana F. Muell. and Psidium guajava L. (Myrtaceae), respectively (Pereira et al 2008). The use of leaves of alternative hosts of S. molina and tests with artificial diets can provide a reduction in mortality especially in the first instar and optimize the results to enable rearing for further research on the outbreak control for parica trees crops.…”
