Biological Control Agents
Pest Control, Biological
Reduviidae
A family of winged insects of the suborder HETEROPTERA, called assassin bugs, because most prey on other insects. However one subfamily, TRIATOMINAE, attacks humans and other vertebrates and transmits Chagas disease.
Phyllachorales
An order of fungi in the phylum ASCOMYCOTA characterized by stromatic perithecial forms in most species. Notable genera are Magnaporthe and Glomerella, the latter having the anamorph (mitosporic form) COLLETOTRICHUM.
Antibiosis
Beetles
Lysobacter
Ascomycota
Beauveria
A mitosporic fungal genus. Teleomorphs are found in the family Clavicipitaceae and include Cordyceps bassiana. The species Beauveria bassiana is a common pathogen of ARTHROPODS and is used in PEST CONTROL.
Pseudomonas fluorescens
Hemiptera
A large order of insects characterized by having the mouth parts adapted to piercing or sucking. It is comprised of four suborders: HETEROPTERA, Auchenorrhyncha, Sternorrhyncha, and Coleorrhyncha.
Wasps
Nematoda
Trichoderma
A mitosporic fungal genus frequently found in soil and on wood. It is sometimes used for controlling pathogenic fungi. Its teleomorph is HYPOCREA.
Spores, Fungal
Reproductive bodies produced by fungi.
Larva
Moths
Insects of the suborder Heterocera of the order LEPIDOPTERA.
Lepidoptera
A large order of insects comprising the butterflies and moths.
Riot Control Agents, Chemical
Fungi
A kingdom of eukaryotic, heterotrophic organisms that live parasitically as saprobes, including MUSHROOMS; YEASTS; smuts, molds, etc. They reproduce either sexually or asexually, and have life cycles that range from simple to complex. Filamentous fungi, commonly known as molds, refer to those that grow as multicellular colonies.
Pseudomonas
Soil Microbiology
The presence of bacteria, viruses, and fungi in the soil. This term is not restricted to pathogenic organisms.
Plant Leaves
Insect Control
Arthropods
Predatory Behavior
Sequence Analysis, DNA
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.
Pythium
Duddingtonia
A genus of ascomycetous mitosporic fungi in the family Orbiliaceae. It is used for the biological control of nematodes in livestock.
Rhizoctonia
Lycopersicon esculentum
Insecticides
Pantoea
A genus of gram-negative, facultatively anaerobic, straight rods which are motile by peritrichous flagella. Most strains produce a yellow pigment. This organism is isolated from plant surfaces, seeds, soil, and water, as well as from animals and human wounds, blood, and urine. (From Bergey's Manual of Determinative Bacteriology, 9th ed)
Phloroglucinol
Erwinia amylovora
Phenazines
Phenazines are nitrogen-containing heterocyclic compounds that have been widely studied for their antibacterial, antifungal, and antiparasitic properties, and can be found in various natural sources such as bacteria and fungi, or synthesized chemically.
Aedes
Hymenoptera
An extensive order of highly specialized insects including bees, wasps, and ants.
Melastomataceae
Insect Vectors
Malus
Oviposition
Bacillus thuringiensis
Heteroptera
A suborder of HEMIPTERA, called true bugs, characterized by the possession of two pairs of wings. It includes the medically important families CIMICIDAE and REDUVIIDAE. (From Dorland, 28th ed)
Endophytes
An endosymbiont that is either a bacterium or fungus living part of its life in a plant. Endophytes can benefit host plants by preventing pathogenic organisms from colonizing them.
Host-Parasite Interactions
The relationship between an invertebrate and another organism (the host), one of which lives at the expense of the other. Traditionally excluded from definition of parasites are pathogenic BACTERIA; FUNGI; VIRUSES; and PLANTS; though they may live parasitically.
Rahnella
Species Specificity
The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.
Rhabditoidea
A superfamily of nematodes of the order RHABDITIDA. Characteristics include an open tube stoma and an excretory system with lateral canals.
Plant Tumors
A localized proliferation of plant tissue forming a swelling or outgrowth, commonly with a characteristic shape and unlike any organ of the normal plant. Plant tumors or galls usually form in response to the action of a pathogen or a pest. (Holliday, P., A Dictionary of Plant Pathology, 1989, p330)
Biomphalaria
Xylariales
An order of ascomycetous FUNGI which includes many economically important plant parasites as well as saprophytes.
Food Chain
The sequence of transfers of matter and energy from organism to organism in the form of FOOD. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant. PLANTS, which convert SOLAR ENERGY to food by PHOTOSYNTHESIS, are the primary food source. In a predator chain, a plant-eating animal is eaten by a larger animal. In a parasite chain, a smaller organism consumes part of a larger host and may itself be parasitized by smaller organisms. In a saprophytic chain, microorganisms live on dead organic matter.
