types of insecticides with examples
These can be inorganic insecticides, which are metals and include the commonly used sulfur, and the less commonly used arsenates, copper and fluorine compounds. Example of Insecticide application in the, This page was last edited on 21 December 2020, at 12:03.  However, research into the causes of CCD was inconclusive as of June 2007. Spraying of especially wheat and corn in Europe is believed to have caused an 80 per cent decline in flying insects, which in turn has reduced local bird populations by one to two thirds.. The inorganic are the ones made from the … Continue reading TYPES OF INSECTICIDE AND THEIR APPLICATION , Pyrethroid pesticides mimic the insecticidal activity of the natural compound pyrethrum, the biopesticide found in pyrethrins. The types of insecticides in this category are: Insecticidal Soap is made of detergent or ivory liquid and can be sprayed on plants to protect it from being eaten by insects. It provides another way of classifying insecticides. Many of the major insecticides are inspired by biological analogues. Type I, among other physiological responses, have a negative temperature coefficient, resembling that of DDT. Botanical insecticides, also known as organic insecticides, are derived from plant extracts. For instance, a gene that codes for a specific Bacillus thuringiensis biocidal protein was introduced into corn (maize) and other species. Contact – These type of insecticides act like bullets that aim only at a particular target to kill insects by its application. Pesticides include all materials that are used to prevent, destroy, repel, attract or reduce pest organisms. There are three different types of insecticides. Milky spore is an example of this type of natural pesticide. Globally they are controlled via the Stockholm Convention on persistent organic pollutants. reed aphids image by Adrian Hillman from Fotolia.com. Systemic insecticides become incorporated and distributed systemically throughout the whole plant. The plant manufactures the protein, which kills the insect when consumed.. Examples of specific synthetic chemical pesticides are glyphosate, Acephate, Deet, Propoxur, Metaldehyde, Boric Acid, Diazinon, Dursban, DDT, Malathion, etc. Insecticides represent a major area of emphasis. Although the classic risk assessment considered this insecticide group (and flupyradifurone specifically) safe for bees, novel research have raised concern on their lethal and sublethal effects, alone or in combination with other chemicals or environmental factors. Some insecticides kill or harm other creatures in addition to those they are intended to kill. They are broad-spectrum systemic insecticides, with rapid action (minutes-hours). The most successful insecticides in this class are the juvenoids (juvenile hormone analogues). Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Therefore, the resistance builds up rapidly. The first insecticide from this class to be registered was Rynaxypyr, generic name chlorantraniliprole.. Efficacy can be related to the quality of pesticide application, with small droplets, such as aerosols often improving performance.. Some insecticides become concentrated as they spread in the food chain. Organochlorines are very slowly decomposing chlorinated organic compounds, which are lipophilic (show much affinity for the fatty tissue of animals). Kaolin clay is a type of clay that, according to the U.S.EPA, was approved as an organic pesticide in 1998. Solid bait and liquid insecticides, especially if improperly applied in a location, get moved by water flow. . , Ryanoids are synthetic analogues with the same mode of action as ryanodine, a naturally occurring insecticide extracted from Ryania speciosa (Salicaceae). Data requirement is less. , Neonicotinoids are synthetic analogues of the natural insecticide nicotine (with much lower acute mammalian toxicity and greater field persistence). The near-worldwide ban on agricultural use of DDT and related chemicals has allowed some of these birds, such as the peregrine falcon, to recover in recent years. Herbicides kill weeds and other plants that grow where they are not wanted. These chemicals are acetylcholine receptor agonists. All are either natural (organic), man-made (synthetic) formulas, or preparations that are used to control or kill unwanted insects. Also, DDT may biomagnify, which causes progressively higher concentrations in the body fat of animals farther up the food chain.

Organophosphates interfere with the enzymes acetylcholinesterase and other cholinesterases, disrupting nerve impulses and killing or disabling the insect. 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. Types of Pesticides • Bactericides for the control of bacteria • Herbicides for the control of weeds • Fungicides for the control of fungi • Insecticides for the control of insects - these can be Ovicides, Larvicides or Adulticides • Miticides for the control of mites • Nematicides for the control of worms • A number of organochlorine pesticides have been banned from most uses worldwide.  The contemporaneous rise of the chemical industry facilitated large-scale production of DDT and related chlorinated hydrocarbons.
