InsecticidesInsecticides (from Latin insectum – insect and caedo - kill) are chemicals from the pesticides group for killing insects – plant pests, their eggs (ovicides) and larvae (larvicides). Insecticides are also used for fighting against insects which are disease carriers and animal ectoparasites as well as with household insects for the protection of the food supply.

Many insecticides are quite toxic therefore their usage at home should be reasonable. Please, study safety requirements for work with toxicants before using insecticides.

Insecticides are divided into three groups by the nature of penetration into the body of the insect-pests (it is necessary to note that most of insecticides use several ways of penetration at the same time). So:

Contact insecticides kill harmful insects with an external contact with any part of their body. These insecticides protect only those parts of the plants to which they are applied to, they depend on precipitation at a great extent and have only a protective effect.

Intestinal insecticides penetrate into insect bowels through its organs while feeding. As a result poison is absorbed into insect body killing it.

Systemic insecticides are able to move through the vascular system of the plant. Their damaging effect occurs when an insect ingests poisoned parts of the plant. In this sense, systemic insecticides are similar to intestinal insecticides. They are quickly absorbed by the plant and, therefore, their effectiveness depends on precipitation quite slightly.

Some insecticides cause obstruction of the respiratory tract of an insect, in consequence of which it dies from asphyxiation.

Insecticides of a wide spectrum of action are used against different types of insect-pests at the same time.

Selective insecticides are used only against a specific type of pests.

Note: systematic application of insecticides of one and the same group inevitably leads to the so called resistance of harmful organisms. The term “resistance” means immunity of different organisms toward some chemicals. Such resistance is often observed in fast-reproducing species that have a very short cycle of development. It is necessary to alternate insecticides of different groups in order to prevent such resistance. Therefore, if there’s a pest which can’t be removed by appropriate means, then it is worth trying to apply the insecticide used against the same pest but from another group.
