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.
A mitosporic fungal genus in the family Clavicipitaceae. It has teleomorphs in the family Nectriaceae. Metarhizium anisopliae is used in PESTICIDES.
Use of naturally-occuring or genetically-engineered organisms to reduce or eliminate populations of pests.
An order of fungi in the phylum ASCOMYCOTA that includes a number of species which are parasitic on higher plants, insects, or fungi. Other species are saprotrophic.
A genus of ascomycetous fungi (ASCOMYCOTA), family Clavicipitaceae, order HYPOCREALES, that grows by infecting insect larvae or mature insects with spores that germinate often before the cocoon is formed.
Reproductive bodies produced by fungi.
An organophosphate cholinesterase inhibitor that is used as an insecticide. It has low mammalian toxicity. (From Merck Index, 11th ed)
A large and heterogenous group of fungi whose common characteristic is the absence of a sexual state. Many of the pathogenic fungi in humans belong to this group.
A genus of TICKS, in the family IXODIDAE, widespread in Africa. Members of the genus include many important vectors of animal and human pathogens.
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)
Organisms, biological agents, or biologically-derived agents used strategically for their positive or adverse effect on the physiology and/or reproductive health of other organisms.
An organophosphorus insecticide that inhibits ACETYLCHOLINESTERASE.
Infestations with arthropods of the subclass ACARI, superorder Acariformes.
Compounds consisting of chains of AMINO ACIDS alternating with CARBOXYLIC ACIDS via ester and amide linkages. They are commonly cyclized.
A mitosporic fungal genus occasionally causing human diseases such as pulmonary infections, mycotic keratitis, endocarditis, and opportunistic infections. Its teleomorph is BYSSOCHLAMYS.
A surfactant that renders a surface wettable by water or enhances the spreading of water over the surface.
A genus of toxic marine GREEN ALGAE found throughout tropical and subtropical seas. One species, Caulerpa taxifolia, is highly invasive and produces the poison caulerpenyne, deadly to marine organisms though not humans.
A family (Aphididae) of small insects, in the suborder Sternorrhyncha, that suck the juices of plants. Important genera include Schizaphis and Myzus. The latter is known to carry more than 100 virus diseases between plants.
A genus of fleas in the family Pulicidae which includes the species that serves as the primary vector of BUBONIC PLAGUE, Xenopsylla cheopis.
A plant species of the genus MELIA, family MELIACEAE, which is toxic to insects. The name is very similar to Melia azadirachta (AZADIRACHTA).
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.
Contamination of bodies of water (such as LAKES; RIVERS; SEAS; and GROUNDWATER.)
Pesticides used to destroy unwanted vegetation, especially various types of weeds, grasses (POACEAE), and woody plants. Some plants develop HERBICIDE RESISTANCE.
Chemicals used to destroy pests of any sort. The concept includes fungicides (FUNGICIDES, INDUSTRIAL); INSECTICIDES; RODENTICIDES; etc.
An order of fungi comprising mostly insect pathogens, though some infect mammals including humans. Strict host specificity make these fungi a focus of many biological control studies.
The relationships of groups of organisms as reflected by their genetic makeup.
