Photo 3. Photo 2. When Telenomus nawai Ashmead or Trichogramma ostriniae Pang & Chen (Hymenoptera: Trichogrammatidae) was inoculated into intact egg masses of Spodoptera litura (Fabricius) that were covered with a scale-hair layer, T. nawai emerged from 76% of the eggs, while emergence of T. ostriniae was from only 3% of the eggs. Spodoptera litura Photo: Natasha Wright, Florida Department of Agriculture and Consumer Services, Bugwood.org, #5190079 . Nov 1, 2013; How does one count the eggs of Spodoptera litura from an egg mass covered with annal hairs without disturbing the eggs? Its facticious hosts of the insect are S. litura, Spodoptera frugiperda (Smith), Spodoptera exigua (Hubner. Similarly the eggs were laid in mass on Sesbania aculeata L. containing 300 - 500 eggs where in 170 eggs per mass, on groundnut observed [7]. To study the life cycle of Spodoptera litura. EPPO (2015) PM 7/124 (1) Spodoptera littoralis, Spodoptera litura, Spodoptera frugiperda, Spodoptera eridania. ), Agrotis spinifera (Hubner. Life History: Females lay eggs in masses of 200 to 300 eggs that are approximately 4-7 mm (0.16-0.27 inches) in diameter and cream to golden brown in color. Question. C. Ooi, Insects and their Natural Enemies Associated Localization of proteinacious factors from the male reproductive system of S. litura which are responsible for modifying the physiology of egg production and egg laying. EPPO Bulletin 48, 330–349. The eggs of the hosts (0–24 h old) are pasted on egg cards and exposed to freshly emerged parasitoids kept in 10 × 2.5 cm size glass vials. Typically Spodoptera egg batches are covered with hairs from the females abdomen, coloured creamy white to light camel with tufts of darker hairs in some species (Fig. ), and C. cephalonica. 1 answer. 2); these hairs are often obvious, but sometimes only a few are present on As the caterpillars of Spodoptera litura enlarge they eat deeper into the leaf; in this photo they have eaten the top surface of the leaf. Growers guide to Bt; egg mass - Merle Shepard, Gerald R. Carner, P.A. 1.1 Identification of adults, larvae and eggs of Spodoptera littoralis and S. litura using real‐time PCR based on TaqMan ® chemistry. Purification and Characterization of the protein; … Egg masses are usually covered with body hair scales and laid on the underside of the host plant leaf. Spodoptera litura is a notorious leaf feeding insect pest of more than one hundred plants around the Asia-Pacific region. EPPO (2018) PM 3/85 Inspection of places of production – Vitis plants for planting. Egg mass and young caterpillars of Spodoptera litura eating the underside of the leaf. As with most moths, Spodoptera adults are nocturnal and not visible during the day. 3.1 Morphological description of Spodoptera litura 3.1.1 Egg In the laboratory, oviposition occurred during night-time and fecundity of individual female was 890.50±16.26 eggs. The eggs of this species are normally laid in an irregular furry mass on the underside of a leaf of a foodplant. EPPO Bulletin 45, 410–444. 1.2 Development, optimisation and validation of this test by BTLH van de Vossenberg and MJ van der Straten (National Plant Protection Organization – NL) was finalised September 2010.
