S. littoralis is found widely in Africa, Mediterranean Europe and Middle Eastern countries.It is a highly polyphagous organism that is a pest of many cultivated plants and crops. caterpillar ( Spodoptera litura [Fabricius]) (Lepi-doptera: Noctuidae) are laid in clusters of 200 to 300 underneath leaves and covered with brown scales from the body of the mother. Distribution and habitat Occurs from India to the Pacific. Sivapragasam , A. The broad host range of the herbivore is due to its ability to downregulate plant defense across different plants. Supriya1*, T.V.K. data sheet on Spodoptera littoralis). As a result of fluctuation, insect can shorten or elongate their life cycle. Females contributed highest number of progeny (mx=338.13) in the life cycle on the 41st day of pivotal age. The caterpillars are known to swarm and travel large distances in search of food. for Spodoptera litura nucleopolyhedrovirus . Singh1, V. Sunitha2, S.K. Vinod3 and C. Narendrareddy1 1Department of Entomology, College of Agriculture, Prof. Jayashankar Telangana State The adult is a stronger flyer; in North America there is an annual migration northward. Spodoptera litura is a notorious leaf feeding insect pest of more than one hundred plants around the Asia-Pacific region. is found in Africa and the Mediterranean region (cf. The Spodoptera complex consists of important species that attack a wide variety of field and vegetable crops. Spodoptera littoralis, also referred to as the African cotton leafworm or Egyptian cotton leafworm or Mediterranean brocade, is a species of moth in the family Noctuidae. Economic Importance for Humans: Positive. The objective of this study was to evaluate the development … Laboratory studies were carried out to determine the effect of temperature on the biology of Spodoptera litura Fab. Newly hatched larvae of the beet armyworm, Spodoptera exigua (Hübner). This fact underscores the need for studies that analyze the nutrition and development of pests on different hosts. Life Table Study of Tobacco Caterpillar Spodoptera litura (F.) (Noctuidae: Lepidoptera) on Different Bt Cotton Hybrids During 120-150 DAS (Days after Sowing) G.B. Applied Entomology and Zoology 8, 205-214. ao Patil RA, Mehta DM, Jat BL (2014) Studies on Life Fecundity Tables of Spodoptera Litura Fabricius on Tobacco Nicotiana tabacum Linnaeus. Two separated testes fused into a single one during the larva-to-pupa metamorphosis, which is believed to contribute … The adult moths are nocturnal and are not often seen. Mochida O (1973) Two important pests, Spodoptera litura and S. littoralis on various crops morphological discrimination of the adult, pupal and larval stages. Life Cycle (3, 10) During the 2nd-5th days following emergence, females lay about 2,500 eggs in egg masses of 200-600 eggs on the leaves of the host-plant ( 4 ) . 3.1 Morphological description of Spodoptera litura 3.1.1 Egg In the laboratory, oviposition occurred during night-time and To study the life span routine of Spodoptera litura. The life cycle can be ... resistance. FEDERICI, in Handbook of Biological Control, 1999. Identification notes for Spodoptera litura and Spodoptera littoralis and some native Spodoptera moths - USDA APHIS PPQ; Steps for the dissection of male Spodoptera moths and notes on distinguishing S. litura and S. littoralis from native Spodoptera species - USDA APHIS PPQ; Data Sheets on Quarantine Pests - European and Mediterranean Plant Protection Organization Spodoptera exigua is considered one of the worst agricultural pests worldwide. Due to its larvae consuming a wide range of vegetation, S. exigua can have a disastrous effect on crop production. Spodoptera litura Photo: Natasha Wright, Florida Department of Agriculture and Consumer Services, Bugwood.org, #5190079 . Localization of proteinacious factors from the male reproductive system of S. litura that happen to be responsible for changing the physiology of egg creation and egg laying. 5 pp. Descriptor(s) : arthropod pests arthropod pests Subject Category: Organism Groups Randolph, N.M. (1963) Life cycle, habits and control of the beet armyworm. Example pests controlled: Beet armyworm (Spodoptera litura) Example applications: Beet crops . The duration of egg, larvae, and pupa lasted for an average of 5.0±0.00 days, 15.45±1.14 and 9.37±1.37 days. The most improtant pests include S. exigua, S. frugiperda, S. litura, and S. littoralis. Spodoptera litura underwent the holometabolous type of development and the studies on biology of S. litura indicated that on an average female moth laid 200-250 eggs in her life span. The identity of Spodoptera litura released effectors that downregulate plant defense are largely unknown. The rice-cotton cutworm ... Life cycle Adults can live for 8 to 10 days Eggs hatch in 4 to 12 days Larvae pass through six instars in about 13 days ( 2001 ) The genus Spodoptera with emphasis on the ecology and natural enemies of the beet armyworm, Spodoptera exigua Hübner in Malaysia . Photograph by Lyle J. Buss, University of Florida. We aimed to study the biodiversity of the microbiota across the life cycle of S. exigua and to provide a better and obtain insight into new pest control strategies. Purification and Characterization of the protein; Determination of the amino acid sequence of the protein. The life cycle is about 25 days, and during that time the female lays between 300 and 600 eggs. Progress Report, Texas Agricultural Station 2287 .
