biological aspects of periga circumstans walker 1855 lepidoptera Saturniidae hemileucinae with larvae reared on khaki and mate plant leaves
Brazilian Journal of Biology, 2011Co-Authors: Alexandre Specht, L M Lorini, Edegar Fronza, Graziela PolettoAbstract:The goal of the present study was to investigate biological aspects of Periga circumstans Walker, 1855 (Lepidoptera: Saturniidae: Hemileucinae) whose larvae were fed on leaves of khaki-plant (Diospyros khaki Linnaeus - Ebenaceae) and Mate-plant (Ilex paraguariensis Saint Hilaire - Aquifoliaceae) leaves. The biological parameters were obtained from specimens kept under controlled conditions: temperature of 25 ± 1 °C, relative humidity of 70 ± 10%, and photoperiod of 12 hours. For each developmental stage, morphological and ethological parameters are described. The larvae passed through six instars with a growth average rate of 1.4 for each instar. The host plants influenced significantly only the total duration of the larval phase, which was prolonged for larvae fed on khaki-plant leaves. Several aspects related to the morphology and the ethology of P. circumstans are similar to those described for Lonomia obliqua Walker, 1855.

aspectos biologicos e morfologicos de leucanella viridescens lepidoptera Saturniidae hemileucinae
Zoologia, 2009Co-Authors: Alexandre Specht, Elio Corseuil, Augusto J Benedetti, Graziela Poletto, Aline Carraro FormentiniAbstract:The goal of this work was to describe aspects of the biology and morphology of Leucanella viridescens (Walker, 1855), a polyphytophagous species that is a pest to several crops of economical interest and whose larvae may cause erucism. Biological parameters were obtained under controlled conditions: temperature of 25 ± 1oC, relative humidity of 70 ± 10%, and a 14 h photophase. Morphological and behavioral aspects were analyzed in each developmental phase. The larval stage had six instars, with an average growth rate of 1.396. A high degree of polyphytophagy was observed, including over 49 host plant species belonging to 25 families, especially Leguminosae, Solanaceae and Salicaceae. The considerable chromatic variability of the adults obtained from the same egg batch corroborates the need for a new taxonomic assessment of L. viridescens viridescens Walker, 1855 and L. viridescens viridior Lemaire, 1973.

Brazilian Journal of Biology, 2007Co-Authors: Alexandre Specht, Aline Carraro Formentini, Elio CorseuilAbstract:The aim of this work was to study biological aspects and the life cycle of Hylesia Metapyrrha in a laboratory. Laboratorial breeding was made at 25 +/- 1 degrees C, 70 +/- 10% UR and 14 hours of photophase, feeding the larvae with guava leaves (Psidium guayava L. - Myrtaceae). Time was evaluated on the days of all the development stages; morphometry was evaluated in millimeters and the pupas mass in grams. The eggs were disposed in groups and covered by urticating abdominal hair. The incubation period lasted 52 days. The larvae, with gregarious habits, presented background black coloration, yellowish scoli and two orange longitudinal lines above and below the spiracles, during the development which lasted an average period of 74.59 days and went through seven instars. The pre-pupa and the pupa stages lasted on average 8.82 and 50.56 days, respectively; the female pupae presented a duration, weight and size which was significantly bigger. The adult stage lasted on average 5.50 days with periods of pre, post and oviposition of 2.30, 1.90 and 1.00 days, respectively. This study broadens the knowledge of the immature stages, biological, morphological and behavioral aspects, until then restricted to the morphology and to registers of the occurrence of the adult forms.

complete mitochondrial genome of the atlas moth attacus atlas lepidoptera Saturniidae and the phylogenetic relationship of Saturniidae species
Gene, 2014Co-Authors: Miaomiao Chen, Yanqun Liu, Mo Chen, Huan Wang, Runxi Xia, Caiyun Zeng, Li QinAbstract:Abstract Mitochondrial genome (mitogenome) can provide information for genomic structure as well as for phylogenetic analysis and evolutionary biology. In this study, we present the complete mitogenome of the atlas moth, Attacus atlas (Lepidoptera: Saturniidae), a well-known silk-producing and ornamental insect with the largest wing surface area of all moths. The mitogenome of A. atlas is a circular molecule of 15,282 bp long, and its nucleotide composition shows heavily biased towards As and Ts, accounting for 79.30%. This genome comprises 13 protein-coding genes (PCGs), two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and an A + T-rich region. It is of note that this genome exhibits a slightly positive AT skew, which is different from the other known Saturniidae species. All PCGs are initiated by ATN codons, except for COI with CGA instead. Only six PCGs use a common stop codon of TAA or TAG, whereas the remaining seven use an incomplete termination codon T or TA. All tRNAs have the typical clover-leaf structure, with an exception for tRNASer(AGN). The A. atlas A + T-rich region contains non-repetitive sequences, but harbors several features common to the Bombycoidea insects. The phylogenetic relationships based on Maximum Likelihood method provide a well-supported outline of Saturniidae, which is in accordance with the traditional morphological classification and recent molecular works.

the complete mitochondrial genome of the ailanthus silkmoth samia cynthia cynthia lepidoptera Saturniidae
Gene, 2013Co-Authors: Yanghu Sima, Mo Chen, Rui Yao, Teng Liu, Xin Jin, Lipeng Wang, Yanqun LiuAbstract:Abstract The complete mitochondrial genome (mitogenome) of the Ailanthus silkmoth, Samia cynthia cynthia (Lepidoptera: Saturniidae) was determined. The circular genome is 15,345 bp long, and presents a typical gene organization and order for sequenced mitogenomes of Bombycidea species. The nucleotide composition of the genome is highly A+T biased, accounting for 79.86%. The AT skew of the genome is slightly negative, indicating the occurrence of more Ts than As, as found in other Saturniidae species. All protein-coding genes (PCGs) are initiated by ATN codons, except for COI and COII, which are tentatively designated by CGA and GTG, respectively, as observed in other insects. Four of 13 PCGs, including COI, COII, ATP6, and ND3, harbor the incomplete termination codons, T or TA. With an exception for tRNASer(AGN), all other tRNAs can form a typical clover-leaf structure of mitochondrial tRNA. The 359 bp A+T-rich region of S. c. cynthia contains non-repetitive sequences, but harbors several features common to the Bombycidea insects, including the motif ATAGA followed by a poly-T stretch of 19 bp, a microsatellite-like (AT)7 element preceded by the ATTTA motif, and a poly-A element upstream tRNAMet. The phylogenetic analyses support the morphology-based current hypothesis that Bombycidae and Saturniidae are monophyletic. Our result confirms that Saturniini and Attacini form a reciprocal monophyletic group within Saturniidae.

the complete mitochondrial genome of the chinese oak silkmoth antheraea pernyi lepidoptera Saturniidae
Acta Biochimica et Biophysica Sinica, 2008Co-Authors: Yanqun Liu, Minhui Pan, Fangyin Dai, Xuwei Zhu, Zhonghuai XiangAbstract:We determined the complete nucleotide sequence of the mitogenome from Chinese oak silkmoth, Antheraea pernyi (Lepidoptera: Saturniidae). The 15,566 bp circular genome contains a typical gene organization and order for lepidopteran mitogenomes. The mitogenome contains the lowest A+T content (80.16%) among the known lepidopteran mitogenome sequences. An unusual feature is the occurrence of more Ts than As, with a slightly negative AT skewness (−0.021), in the composition of the major genome strand. All proteincoding genes are initiated by ATN codons, except for cytochrome oxidase subunit I, which is proposed by the TTAG sequence as observed in other lepidopterans. All transfer RNAs (tRNAs) have a typical clover-leaf structure of mitochondrial tRNA, except for tRNA Ser (AGN), the DHU arm of which could not form a stable stem-loop structure. Two aligned sequence blocks with a length of more than 50 bp and 90% of the sequence identity were identified in the A+T-rich region of the Saturniidae and Bombycoidae species.

aspectos morfologicos de lonomia obliqua walker lepidoptera Saturniidae
Neotropical Entomology, 2001Co-Authors: Lorini Lisete M, Elio CorseuilAbstract:Lonomia obliqua Walker (Lepidoptera, Saturniidae) has urticant spines in larval stages. This species may cause death as a result of haemorrhages caused by a toxin released from the caterpillar's spines onto the skin of the victim when touched. In order to determine the morphological features of this species, studies were performed at the Laboratory of Entomology of the Pontificia Universidade Catolica do Rio Grande do Sul. The morphological aspects of eggs, larvae, pupae and adults are discussed as well as illustrated with pictures and drawings. The eggs are light green, 1.98 mm mean height, 1.45 mm large and 1.61 mm long. From the first to the sixth larval instar, the insect has spines on the body with different sizes and they are green-brownish with strong and dark heads. The mean sizes are 5.19 mm long at the first larval instar and 53.49 mm at the sixth instar. The head capsules are 1.01 mm and 4.83 mm wide at the first and sixth instars respectively. The mean lengths of the pupae are 28.73 mm for males and 30.23 mm for females. Adults have sexual dimorphism in which the male is smaller and yellow and the female is larger and grey-brownish. The mean adult wing span is 60.47 mm in males and 80.33 mm in females.

management of hylesia nanus lepidoptera Saturniidae on eucalyptus myrtaceae plantations
Florida Entomologist, 2017Co-Authors: Marcus Vinicius Masson, Wagner De Souza Tavares, Deivide Walace Vitor Pereira, Willian Costa Matos, Fabricio De Almeida Lopes, Pedro Jose Ferreirafilho, Carlos Frederico Wilcken, José Cola ZanuncioAbstract:The management of Hylesia nanus (Walker, 1855) (Lepidoptera: Saturniidae: Hemileucinae), a defoliator of Eucalyptus spp. (Myrtales: Myrtaceae), was evaluated on the northern coast of Bahia state, Brazil by performing three connected experiments: (1) monitoring of H. nanus moths using light traps; (2) biological control of H. nanus pupae releasing the endoparasitoid Palmistichus elaeisis Delvare & La Salle, 1993 (Hymenoptera: Eulophidae: Chalcidoidea), and (3) chemical control of H. nanus larvae with one spraying of Talstar 100 EC + Agral. The light traps effectively assisted the monitoring and control of H. nanus moths, with a population peak of 7,392.85 individuals collected in a single nocturnal period. Palmistichus elaeisis was recovered from the H. nanus pupae 96 hours post release with parasitism rate of 22.58 ± 2.95%, indicating its ability to parasitize and contribute towards insect control in the field. Besides, this parasitoid can be integrated with the monitoring using light traps. Chemical control was highly effective against the last instar H. nanus larvae, with only 10.5 ± 3.0 larvae survivors per treetrunk 24 hours post spraying. Thus, the monitoring using light traps, control of pupae by releasing P. elaeisis released, and chemical control of last instar larvae are methods that can be integrated into a management plan for H. nanus in the field. Key Words: chemical control; light trap; Palmistichus elaeisis ; Tachinidae Resumo O manejo de Hylesia nanus Walker (Lepidoptera: Saturniidae), um desfolhador de especies de Eucalyptus (Myrtales: Myrtaceae), foi avaliado no litoral norte do estado da Bahia, Brasil atraves da realizacao de tres experimentos conectados: (1) monitoramento de mariposas de H. nanus utilizando armadilhas luminosas, (2) controle biologico de pupas de H. nanus liberando o endoparasitoide Palmistichus elaeisis Delvare & La Salle (Hymenoptera: Eulophidae) e (3) controle quimico de larvas de H. nanus com uma pulverizacao de bifentrina + etilenoxi. As armadilhas luminosas assistiram de forma eficaz o monitoramento e controle de mariposas de H. nanus , com um pico populacional medio (± EP) de 801 ± 438 individuos coletados por armadilha em um periodo noturno de 23 d. Palmistichus elaeisis foi recuperado das pupas de H. nanus 96 h apos a liberacao com taxa de parasitismo de 23 ± 3%, indicando uma capacidade de parasitar e contribuir para o controle de insetos no campo. Alem disso, este parasitoide pode ser integrado com o monitoramento com armadilhas luminosas. O controle quimico foi altamente eficaz contra as larvas de ultimo instar de H. nanus , com apenas 11 ± 3 larvas sobreviventes por caule 24 h apos a pulverizacao. Assim, o monitoramento de mariposas utilizando armadilhas luminosas, controle de pupas utilizando P. elaeisis liberado e controle quimico das larvas de ultimo instar sao metodos que podem ser integrados em um plano de manejo para H. nanus.

Journal of The Lepidopterists Society, 2012Co-Authors: Wagner De Souza Tavares, Olaf H. H. Mielke, Carlos Frederico Wilcken, Leroy Simon, Jose Eduardo Serrao, José Cola ZanuncioAbstract:ABSTRACT. The moth Citioica anthonilis (Herrich-Schaeffer, [1854]) (Lepidoptera: Saturniidae: Ceratocampinae) occurs in areas of preserved forests, where it is a significant defoliator of Piptadenia gonoacantha (Martius) Macbride (Fabaceae) trees. In this study, caterpillars of fourth instar C. anthonilis were collected from the ground after falling from a P. gonoacantha tree in a herbarium and were reared in the laboratory. Pupae of C. anthonilis, the velvetbean caterpillar Anticarsia gemmatalis Hubner, 1818 (Lepidoptera: Noctuidae), and the flour beetle Tenebrio molitor Linnaeus, 1758 (Coleoptera: Tenebrionidae) were each parasitized by mated parasitoid females wasp Palmistichus elaeisis Delvare & LaSalle, 1993 (Hymenoptera: Eulophidae). Data were collected relating to the levels of parasitism and emergence rates of P. elaeisis per host pupa, and the size of the host pupae. Our results show that the fecundity of P. elaeisis was highest in C. anthonilis hosts, probably because of the greater size of thes...

Species of Lepidoptera defoliators of Eucalyptus as new host for the parasitoid Palmistichus elaeisis (Hymenoptera: Eulophidae)
Instituto de Tecnologia do Paraná (Tecpar), 2008Co-Authors: Teresinha Vinha Zanuncio, Dirceu Pratissoli, José Cola Zanuncio, Marcelo Teixeira TavaresAbstract:Pupae of Thyrinteina arnobia (Stoll) and Thyrinteina leucoceraea Rindge (Lepidoptera: Geometridae) were obtained from Eucalyptus cloeziana F. Muell and Eucalyptus urophylla S.T. Blake plants, respectively. Specimens of a parasitoid emerged from T. arnobia pupae and also found parasitising T. leucoceraea pupae in the field were identified as Palmistichus elaeisis Delvare and LaSalle (Hymenoptera: Eulophidae). This is the first report on P. elaeisis parasitizing T. arnobia and T. leucoceraea pupae in natural conditions in Brazil. P. elaeisis also parasitized these hosts and Bombyx mori Linnaeus (Lepidoptera: Bombycidae), Anticarsia gemmatalis Hubner, Pseudaletia sequax Franclemont, Alabama argillacea Huebner (Lepidoptera: Noctuidae), Dirphia moderata Bouvier (Lepidoptera: Saturniidae) and Halysidota pearsoni Watson (Lepidoptera: Arctiidae) in the laboratory. The production and release of P. elaeisis could be an efficient alternative for controlling Lepidoptera defoliators in eucalyptus plantations.Pupas de Thyrinteina arnobia (Stoll) e Thyrinteina leucoceraea Rindge (Lepidoptera: Geometridae) foram coletadas em Eucalyptus cloeziana F.
