Insect

Insecticides are substances used to kill insects.
Humans regard certain insects as pests, and attempt to control them using insecticides, and a host of other techniques.

Rotenone

rotenoidrotenolone
Four extracts of plants are in commercial use: pyrethrum, rotenone, neem oil, and various essential oils
Rotenone is an odorless, colorless, crystalline isoflavone used as a broad-spectrum insecticide, piscicide, and pesticide.

Pesticide application

applicationsprayingResponsible use
Efficacy can be related to the quality of pesticide application, with small droplets, such as aerosols often improving performance.
Pesticide application refers to the practical way in which pesticides, (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).

Pyrethrum

pyrethroidC. coccineumpyrethrum powder
Four extracts of plants are in commercial use: pyrethrum, rotenone, neem oil, and various essential oils 1. Natural insecticides, such as nicotine, pyrethrum and neem extracts, made by plants as defenses against insects. Pyrethroid pesticides mimic the insecticidal activity of the natural compound pyrethrum, the biopesticide found in pyrethrins.
Pyrethrum is also the name of a natural insecticide made from the dried flower heads of Chrysanthemum cinerariifolium and Chrysanthemum coccineum.

Sulfur

sulphurSbrimstone
These can be inorganic insecticides, which are metals and include arsenates, copper and fluorine compounds, which are less commonly used, and the commonly used sulfur.
The element sulfur is used in matches, insecticides, and fungicides.

Larvicide

larvicidallarvicideslarvaciding
They include ovicides and larvicides used against insect eggs and larvae, respectively.
A larvicide (alternatively larvacide) is an insecticide that is specifically targeted against the larval life stage of an insect.

DDT

dichlorodiphenyltrichloroethanep,p'-DDTDichlorodiphenyltrichloroethane (DDT)
The best known organochloride, DDT, was created by Swiss scientist Paul Müller.
Dichlorodiphenyltrichloroethane, commonly known as DDT, is a colorless, tasteless, and almost odorless crystalline chemical compound, an organochlorine, originally developed as an insecticide, and ultimately becoming infamous for its environmental impacts.

RNA interference

RNAiregulatory RNARNA interference (RNAi)
The technique has been expanded to include the use of RNA interference RNAi that fatally silences crucial insect genes.
The pathway is also used as a practical tool in biotechnology, medicine and insecticides.

Pesticide resistance

resistanceherbicide resistanceresistant
The technique is expected to replace many other insecticides, which are losing effectiveness due to the spread of pesticide resistance.
The Insecticide Resistance Action Committee (IRAC) definition of insecticide resistance is 'a heritable change in the sensitivity of a pest population that is reflected in the repeated failure of a product to achieve the expected level of control when used according to the label recommendation for that pest species'.

Nicotine

nicotine addictionnicotine sulfatenicotinoid
1. Natural insecticides, such as nicotine, pyrethrum and neem extracts, made by plants as defenses against insects. Neonicotinoids are synthetic analogues of the natural insecticide nicotine (with much lower acute mammalian toxicity and greater field persistence).
Nicotine has been used as an insecticide since at least the 1690s, in the form of tobacco extracts (although other components of tobacco also seem to have pesticide effects).

Neonicotinoid

neonicotinoidsban on neonicotinoidsnicotinoid
Neonicotinoids are synthetic analogues of the natural insecticide nicotine (with much lower acute mammalian toxicity and greater field persistence).
Neonicotinoids (sometimes shortened to neonics ) are a class of neuro-active insecticides chemically similar to nicotine.

Beauveria bassiana

white muscardine diseaseBeauveriaB. bassiana
Other biological insecticides include products based on entomopathogenic fungi (e.g., Beauveria bassiana, Metarhizium anisopliae), nematodes (e.g., Steinernema feltiae) and viruses (e.g., Cydia pomonella granulovirus).
It is being used as a biological insecticide to control a number of pests such as termites, thrips, whiteflies, aphids and different beetles.

Imidacloprid

Advantageconfidor
Imidacloprid may be the most common.
Imidacloprid is a systemic insecticide that acts as an insect neurotoxin and belongs to a class of chemicals called the neonicotinoids which act on the central nervous system of insects.

Pyrethroid

pyrethroidspyrethoidssynthetic pyrethroid
Pyrethroid pesticides mimic the insecticidal activity of the natural compound pyrethrum, the biopesticide found in pyrethrins.
A pyrethroid is an organic compound similar to the natural pyrethrins produced by the flowers of pyrethrums (Chrysanthemum cinerariaefolium and C. coccineum). Pyrethroids constitute the majority of commercial household insecticides.

Bacillus thuringiensis

BtB. thuringiensisB . thuringiensis
For instance, a gene that codes for a specific Bacillus thuringiensis biocidal protein was introduced into corn (maize) and other species.
During sporulation, many Bt strains produce crystal proteins (proteinaceous inclusions), called δ-endotoxins, that have insecticidal action.

Pyrethrin

pyrethrinscinerinpyrethrin organic compounds
Pyrethroid pesticides mimic the insecticidal activity of the natural compound pyrethrum, the biopesticide found in pyrethrins.
The pyrethrins are a class of organic compounds normally derived from Chrysanthemum cinerariifolium that have potent insecticidal activity by targeting the nervous systems of insects.

Organophosphate

organophosphatesphosphate esterorganophosphate pesticide
Organophosphates are another large class of contact insecticides.
Like most functional groups organophosphates occur in a diverse range of forms, with important examples including key biomolecules such as DNA, RNA and ATP, as well as many insecticides, herbicides, and nerve agents.

Insect growth regulator

insect growth regulatorsjuvenile hormone mimic
Insect growth regulator (IGR) is a term coined to include insect hormone mimics and an earlier class of chemicals, the benzoylphenyl ureas, which inhibit chitin (exoskeleton) biosynthesis in insects Diflubenzuron is a member of the latter class, used primarily to control caterpillars that are pests.
IGRs are typically used as insecticides to control populations of harmful insect pests such as cockroaches and fleas.

Diflubenzuron

Insect growth regulator (IGR) is a term coined to include insect hormone mimics and an earlier class of chemicals, the benzoylphenyl ureas, which inhibit chitin (exoskeleton) biosynthesis in insects Diflubenzuron is a member of the latter class, used primarily to control caterpillars that are pests.
Diflubenzuron is an insecticide of the benzoylurea class.

Ryanoid

ryanoid insecticides
Ryanoids are synthetic analogues with the same mode of action as ryanodine, a naturally occurring insecticide extracted from Ryania speciosa (Flacourtiaceae).
Ryanoids are a class of insecticides which share the same mechanism of action as the alkaloid ryanodine.

Tebufenozide

A more recent type of IGR is the ecdysone agonist tebufenozide (MIMIC), which is used in forestry and other applications for control of caterpillars, which are far more sensitive to its hormonal effects than other insect orders.
Tebufenozide is an insecticide that acts as a molting hormone.

Arsenic

AsAs 2 yellow arsenic
DDT was introduced to replace lead and arsenic-based compounds, which were in widespread use in the early 1940s.
Arsenic and its compounds, especially the trioxide, are used in the production of pesticides, treated wood products, herbicides, and insecticides.

Toxaphene

chlorocamphene
These include: aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex and toxaphene.
Toxaphene was an insecticide used primarily for cotton in the southern United States during the late 1960s and 1970s.

Malaria

cerebral malariamalarial fevermalarial
It has no observable acute toxicity in rats and is approved by World Health Organization (WHO) for use in drinking water cisterns to combat malaria.
The risk of disease can be reduced by preventing mosquito bites through the use of mosquito nets and insect repellents, or with mosquito control measures such as spraying insecticides and draining standing water.

Endrin

Endrin aldehyde
These include: aldrin, chlordane, DDT, dieldrin, endrin, heptachlor, mirex and toxaphene.
It was primarily used as an insecticide, as well as a rodenticide and piscicide.
