“…Stadium pupa bervariasi berlangsung selama 5-7 hari. Karakteristik pupa betina N. coleta mirip dengan pupa betina Agrotis malefida yang lebih besar dan lebih berat daripada pupa jantan dan memiliki umur yang bervariasi (Specht et al 2013). Atmaja dan Djatnika (1999) menyatakan lama stadium prepupa dan pupa N. coleta masing-masing 1 dan 7 hari.…”

“…Telur P. auratalis hampir menyerupai telur N. coleta, tetapi terdapat warna hitam di tengah telur P. auratalis (Gambar 2a). Pada umumnya, bentuk dan ukuran telur dari ordo Lepidoptera hampir sama tetapi terdapat perbedaan pada warna kulit permukaan telur dari masing-masing spesies karena adanya pengaruh suhu di sekitar lingkungan tempat serangga tumbuh dan berkembang (García-Barros 2000; Kok et al 2011;Specht et al 2013). Keberhasilan telur P. auratalis menetas menjadi larva sekitar 75%.…”

ABSTRAKSambung nyawa (Gynura procumbens) merupakan salah satu tanaman obat yang mempunyai beragam manfaat bagi kesehatan, bermanfaat sebagai analgesik hingga antimikroba. Pada tanaman ini terdapat dua spesies larva dari ordo Lepidoptera yang merupakan hama perusak daun, sehingga menghambat pertumbuhan sambung nyawa. Tujuan penelitian untuk mengetahui perilaku dan siklus hidup dari kedua jenis ulat yang ditemukan di pertanaman sambung nyawa, sebagai dasar dalam penelitian pengendalian hama pada pertanaman sambung nyawa. Penelitian dilakukan di Laboratorium Hama Balai Penelitian Tanaman Rempah dan Obat (Balittro) sejak Januari sampai April 2016. Larva yang dikumpulkan dari lapangan dipelihara dan dikembangbiakkan di laboratorium. Parameter yang diamati meliputi stadium dan karakteristik tiap stadium dari siklus hidup dua spesies hama yang ditemukan di pertanaman sambung nyawa. Hasil penelitian menunjukkan bahwa dua jenis larva yang ditemukan di pertanaman sambung nyawa adalah Nyctemera coleta dan Paliga auratalis, termasuk dalam ordo Lepidoptera. Stadium larva N. coleta merupakan stadium yang paling panjang dengan kisaran umur larva rata-rata 24 hari. Larva N. coleta merusak daun dengan memakan jaringan daun sehingga meninggalkan tulang-tulang daun. Stadium yang paling panjang pada P. auratalis adalah stadium pupa dengan rata-rata kisaran umur stadium 13,1 hari. Larva P. auratalis merusak daun sambung nyawa dengan memakan daun dan juga merekatkan sisi-sisi daun menggunakan saliva yang dikeluarkan dari mulutnya. Kata kunci: Gynura procumbens, Nyctemera coleta, Paliga auratalis, larva, pupa ABSTRACT Gynura procumbens is one of medicinal plants useful for human health as analgesic and antimicrobe. There are two species of larvae from Lepidoptera order found as a pest for damaging leaf, hence inhibiting growth of G. procumbens. The aims of the study were to identify and determine the behaviour and life cycle of both types of larvae found on G. procumbens. This study was conducted in Pest Laboratory of the Indonesian Spices and Medicinal Crops ResearchInstitute (ISMCRI) from January to April 2016. The larvae were collected from the field in Bogor area, mass-reared and grown in laboratory. The parameters observed were the stadium and the characteristics of each stadium of those two pest species found on G. procumbens plant. The result showed that two species of larvaes found on G. procumbens were identified as Nyctemera coleta and Paliga auratalis. The larvae of N. coleta was the longest stadium for 24 days. It damaged plant by eating leaves tissues and leaving only the petiole. The longest stadium of P. auratalis was pupae at 13.1 days. P. auratalis larvae destroyed the leaves of G. procumbens by chewing the leaf tissue and attached the leaf sides using secreted saliva.Key words: Gynura procumbens, Nyctemera coleta, Paliga auratalis, larvae, pupae PENDAHULUANPengembangan agroindustri tanaman obat di Indonesia memiliki prospek yang baik, karena didukung oleh besarnya kekayaan sumber daya alam Indonesia sebagai sumber ba...

Reproductive potential of Spodoptera eridania (Stoll) (Lepidoptera: Noctuidae) in the laboratory: effect of multiple couples and the size

et al. 2016

View full text Add to dashboard Cite

This study aimed to evaluate the effect of keeping three couples in the same cage, and the size of adults emerged from small, medium-sized and large pupae (278.67 mg; 333.20 mg and 381.58 mg, respectively), on the reproductive potential of S. eridania (Stoll, 1782) adults, under controlled conditions (25 ± 1 °C, 70% RH and 14 hour photophase). We evaluated the survival, number of copulations, fecundity and fertility of the adult females. The survival of females from these different pupal sizes did not differ statistically, but the survival of males from large pupae was statistically shorter than from small pupae. Fecundity differed significantly and correlated positively with size. The number of effective copulations (espematophores) and fertility did not vary significantly with pupal size. Our results emphasize the importance of indicating the number of copulations and the size of the insects when reproductive parameters are compared.Keywords: Southern armyworm, spermatophore, fertility, reproduction.Potencial reprodutivo de Spodoptera eridania (Stoll) (Lepidoptera: Noctuidae) em laboratório: efeito de múltiplos casais e do tamanho ResumoEste estudo objetivou avaliar o efeito de confinar três casais em cada gaiola e o tamanho de adultos emergidos de pupas pequenas, medias e grandes (278,67 mg, 333,20 mg e 381,58 mg, respectivamente), sobre o potencial reprodutivo de S. eridania (Stoll, 1782), em condições controladas (25 ± 1 °C, 70% UR e 14 horas de fotofase). Avaliou-se a sobrevivência, o número de cópulas, fecundidade e fertilidade dos adultos. A sobrevivência não diferiu significativamente entre fêmeas provenientes de pupas de diferentes tamanhos, mas os machos oriundos de pupas grandes tiveram sobrevivência significativamente menor que os demais tamanhos. A fecundidade diferiu significativamente e correlacionou-se positivamente com o tamanho. O número de cópulas (espematóforos) e a fertilidade não variaram em função do peso pupal. Os resultados enfatizam a importância de indicar o número de cópulas e o tamanho dos insetos estudados para que comparações entre os parâmetros reprodutivos possam ser efetuadas.Palavras-chave: lagarta militar do Sul, espermatóforo, fertilidade, reprodução.

“…nov. appears to be temporally restricted from March to June (Fig. 35), which further suggests that this species has a single generation per year and go through larval (as prepupae) and pupal estival diapauses as observed in other species of Feltia, such as F. brachystria, F. gypaetina (Guenée, 1852) and F. robusta (Blanchard, 1852) (Specht et al 2004(Specht et al , 2013Bentancourt & Scatoni 2006). Both these areas (higher elevation grasslands) and months of the year (autumn and early winter) are usually less attended by collectors, which may in part explain the small number or complete absence of specimens of this species in collections.…”

The taxonomy of the hitherto unplaced taxon Porosagrotis carolia Schaus, 1929 is evaluated and the name is taken out of taxonomic limbo and combined with Feltia Walker, 1856. Feltia carolia comb. nov., described from a single female specimen, is redescribed, including the first description of the male. Head, thorax and its appendages, and male and female genitalia are illustrated through photographs and line drawings; photographs of the holotype and a distribution map for the species is provided. Additionally, the spatio-temporal occurrence of the species in Rio Grande do Sul was assessed by monthly standardized samplings with light traps from January of 1998 to December of 1999 in ten different physiographical zones of the state. Our results suggest that F. carolia comb. nov. is univoltine and goes through prepupal and pupal estival diapauses. The assessment of the distribution of the species, based on the standardized samplings and specimens deposited in entomological collections, suggests that F. carolia comb. nov. is restricted to the southern Brazilian Campos, a mostly neglected environment discontinuously distributed in mountainous plateaus of the southern Mata Atlântica biome.
