Spodoptera
Moths
Insects of the suborder Heterocera of the order LEPIDOPTERA.
Nucleopolyhedrovirus
A genus of the family BACULOVIRIDAE, subfamily Eubaculovirinae, characterized by the formation of crystalline, polyhedral occlusion bodies in the host cell nucleus. The type species is Autographa californica nucleopolyhedrovirus.
Baculoviridae
Family of INSECT VIRUSES containing two subfamilies: Eubaculovirinae (occluded baculoviruses) and Nudibaculovirinae (nonoccluded baculoviruses). The Eubaculovirinae, which contain polyhedron-shaped inclusion bodies, have two genera: NUCLEOPOLYHEDROVIRUS and GRANULOVIRUS. Baculovirus vectors are used for expression of foreign genes in insects.
Larva
Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.
Insect Viruses
Pest Control, Biological
Ascoviridae
A family of insect viruses causing disease in lepidopterous larvae, most commonly from species of the owlet moth family Noctuidae. There is one genus: Ascovirus.
Sf9 Cells
Cell line derived from SF21 CELLS which are a cell line isolated from primary explants of SPODOPTERA FRUGIPERDA pupal tissue.
Bacillus thuringiensis
A species of gram-positive bacteria which may be pathogenic for certain insects. It is used for the biological control of the Gypsy moth.
Insects
The class Insecta, in the phylum ARTHROPODA, whose members are characterized by division into three parts: head, thorax, and abdomen. They are the dominant group of animals on earth; several hundred thousand different kinds having been described. Three orders, HEMIPTERA; DIPTERA; and SIPHONAPTERA; are of medical interest in that they cause disease in humans and animals. (From Borror et al., An Introduction to the Study of Insects, 4th ed, p1)
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.

Ecdysteroids
Steroids that bring about MOLTING or ecdysis in insects. Ecdysteroids include the endogenous insect hormones (ECDYSONE and ECDYSTERONE) and the insect-molting hormones found in plants, the phytoecdysteroids. Phytoecdysteroids are natural insecticides.
Cloning, Molecular
Rhabditida
Viral Structural Proteins
Viral proteins that are components of the mature assembled VIRUS PARTICLES. They may include nucleocapsid core proteins (gag proteins), enzymes packaged within the virus particle (pol proteins), and membrane components (env proteins). These do not include the proteins encoded in the VIRAL GENOME that are produced in infected cells but which are not packaged in the mature virus particle,i.e. the so called non-structural proteins (VIRAL NONSTRUCTURAL PROTEINS).
Insect Control
The reduction or regulation of the population of noxious, destructive, or dangerous insects through chemical, biological, or other means.
Insecticides
Densovirus
A genus of PARVOVIRIDAE, subfamily DENSOVIRINAE, comprising helper-independent viruses containing only two species. Junonia coenia densovirus is the type species.
Pupa
An inactive stage between the larval and adult stages in the life cycle of insects.
Biological Control Agents
Fat Body
A nutritional reservoir of fatty tissue found mainly in insects and amphibians.
Genetic Vectors
DNA molecules capable of autonomous replication within a host cell and into which other DNA sequences can be inserted and thus amplified. Many are derived from PLASMIDS; BACTERIOPHAGES; or VIRUSES. They are used for transporting foreign genes into recipient cells. Genetic vectors possess a functional replicator site and contain GENETIC MARKERS to facilitate their selective recognition.

Granulovirus
A genus of the family BACULOVIRIDAE, subfamily Eubaculovirinae, characterized by ovicylindrical occlusion bodies. The type species is Cydia pomonella granulovirus.
Bacterial Toxins
Wasps
Any of numerous winged hymenopterous insects of social as well as solitary habits and having formidable stings.

Blotting, Southwestern
A method that is used to detect DNA-protein interactions. Proteins are separated by electrophoresis and blotted onto a nitrocellulose membrane similar to Western blotting (BLOTTING, WESTERN) but the proteins are identified when they bind labeled DNA PROBES (as with Southern blotting (BLOTTING, SOUTHERN)) instead of antibodies.
Volatile Organic Compounds
Digestive System
A group of organs stretching from the MOUTH to the ANUS, serving to breakdown foods, assimilate nutrients, and eliminate waste. In humans, the digestive system includes the GASTROINTESTINAL TRACT and the accessory glands (LIVER; BILIARY TRACT; PANCREAS).
Bombyx
A genus of silkworm MOTHS in the family Bombycidae of the order LEPIDOPTERA. The family contains a single species, Bombyx mori from the Greek for silkworm + mulberry tree (on which it feeds). A native of Asia, it is sometimes reared in this country. It has long been raised for its SILK and after centuries of domestication it probably does not exist in nature. It is used extensively in experimental GENETICS. (From Borror et al., An Introduction to the Study of Insects, 4th ed, p519)

Sequence Alignment
The arrangement of two or more amino acid or base sequences from an organism or organisms in such a way as to align areas of the sequences sharing common properties. The degree of relatedness or homology between the sequences is predicted computationally or statistically based on weights assigned to the elements aligned between the sequences. This in turn can serve as a potential indicator of the genetic relatedness between the organisms.
