Insecticides- Chemicals used to manage insects and other related creatures, such as ticks, spiders, and centipedes. Microbial Insecticides- Naturally occurring insect-disease microorganisms that are lethal to a specific group of insects. Molluscicides- Chemicals used to control snails or slugs. Pheromones- Chemicals used to attract insects. Carnivorous predators especially (for example, oviparous spiders of corn ear worm eggs), do not eat plants, and have little resistance to many chemicals, naturally occurring or otherwise. Once natural predator populations are down, more pesticides must be used, and hence resistance builds up much more quickly, predator populations decline.

Several of the esters derived from these acids and m -phenoxybenzyl or α-cyano- m -phenoxybenzyl alcohols were found to be effective insecticides.

Even for these, pyrethrum, nicotine, rotenone, hellebore, ryania, and sabadilla, there is a paucity of information on mammalian toxicology and environmental by: The existence of naturally occurring biological control agents is one reason that many plant-feeding insects do not ordinarily become economic pests.
The importance of such agents often becomes quite apparent when pesticides applied to control one pest cause an outbreak of other pests because of the chemical destruction of important natural Cited by: The handbook of naturally occurring insecticidal toxins Opender Koul.

Esters of chrysanthemic acid are naturally occurring insecticides. This book provides an overview on a large variety of pesticide-related topics, organized in three sections.
The first part is dedicated to the "safer" pesticides derived from natural materials, the design and the optimization of pesticides formulations, and the techniques for pesticides application.
The second part is intended to demonstrate the agricultural products, Cited by: The first section of the book covers chemistry and biological activity of major classes of naturally occurring pesticides, including the development of more potent insecticides based on natural lead-in structures.
The second section consists of monographs on each compound by by: This book reviews the uses and toxicology of insecticides. Chapters are as follows: classification and formulations of insecticides; inorganic insecticides; naturally occurring insecticides; organochlorines; organophosphates; carbamates; synthetic pyrethroids; miscellaneous insecticides; bio-pesticides; toxicity and synergism of insecticides; bioassays; mode of action of insecticides Cited by: 6.

Some fungicides and insecticides are made of naturally occurring ingredients and are considered acceptable for organic gardening.

Natural and synthetic methylxanthines inhibit insect feeding and are pesticidal at concentrations known to occur in plants.
These effects are due primarily to inhibition of phosphodiesterase activity and to an increase in intracellular cyclic adenosine monophosphate. At lower concentrations, methylxanthines are potent synergists of other pesticides known to Cited by: the benefits derived from naturally occurring biological controls, through the elimination or reduction in the use of pesticides toxic to natural enemies.
The main objective of this book chapter studying the insecticide side effects on development. One of the most commonly used naturally-occurring pesticides are the pyrethrins. The pyrethrins are natural insecticides extracted from chrysanthemums.
Certification programs usually allow the use of pyrethrums, rotenone, ryania, and. Insecticide, any toxic substance that is used to kill insects. Such substances are used primarily to control pests that infest cultivated plants or to eliminate disease-carrying insects in specific areas.

Mercury is a heavy metal that occurs naturally in minerals and rocks. Release of mercury from natural sources has been relatively constant over time. However, anthropogenic release of mercury has increased significantly in recent years primarily due to increased fossil fuel mining and combustion.

Natural toxins are a source of new chemical classes of pesticides, as well as environmentally and toxicologically safer molecules than many of the currently used pesticides.
Furthermore, they often have molecular target sites that are not exploited by currently marketed pesticides. Naturally Occurring Insecticides.
Marcel Dekker; New York Cited by: Biopesticides are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals.
For example, canola oil and baking soda have pesticidal applications and are considered biopesticides. As of Aprilthere are registered biopesticide active ingredients and active biopesticide.
Biological Insecticides “Biologicals” are naturally-occurring insecticidal organisms, usually bacteria, which attack only specific pests.
Biologicals are and always have been central to organic pest control because they are highly effective, insect-specific, biodegradable and non-toxic to humans, animals, beneficial insects and the environment. The contact insecticides can be divided into two main groups: naturally occurring compounds and synthetic organic ones.
The naturally occurring contact insecticides include nicotine, developed from tobacco ; pyrethrum, obtained from flowers of Chrysanthemum cinerariaefolium and Tanacetum coccineum ; rotenone, from the roots of Derris species.
Other natural analogues of nicotine have been shown to have significant insecticidal properties and one, anabasine or neonicotine (Fig. 2), has been produced as an insecticide from the shrub, Anabasis aphylla, in the Soviet Union. Synthetic variations of nicotine such as 5'-methylnornicotine have been demonstrated to be effective insecticides.

Many organic compounds are produced by plants for the purpose of defending the host plant from predation. A trivial case is tree rosin, which is a natural ically, the production of oleoresin by conifer species is a component of the defense response against insect attack and fungal pathogen infection.
