Insecticides (General Overview)
\n
Insecticide is a substance or a mixture of substances used for killing insects. It is well known fact that many protozoal bacteria diseases are transmitted from man to man by insects. One may combat these diseases not only by means of prohylactic drugs but also by the destruction of the insects carriers.
\n
Insecticide is a chemical compound that is lethally toxic to insects either by ingestion or by body contact. It is applied to vegetation, crops and insect breeding areas either as liquid spray or as dry powder.
\n
They are used in agriculture, medicine, industry and household. The use of insecticides is believed to be one of the major factors behind the increase in agricultural productivity in 20th century.
\n
Nearly, all insecticides have the potential to significantly after ecosystem, many are toxic to human and others are concentrated in food chain. It is necessary to balance agricultural needs with environmental and health issues when using insecticides. It is crucially important that all the rural areas in Nigeria are being educated on the need to eradicate insects especially mosquitoes that might breed around the environment and transmit malaria to people living within the enclave.
\n
Integrated Pest Management (IPM) in the home being with restricting the availability of insects of three vital commodities; shelter, water and food. If insects become a problem despite such measures, IPM seeks to control them using the safest possible methods targeting the approach to the particular pest.
\n
Years now, efforts are geared towards controlling malaria infestation both in urban and rural areas. A lot of measures are being taken to reduce the number of death as a result of malaria.
\n
We hear now and then that numbers being quoted by the analyst that died of malaria attack. Thus, free mosquitoes treated nets are always distributed to families and individuals all in a bid to reduce malaria attack from mosquito bite.
\n
In the light of this, it is necessary to study God-given substances in this case, plant that has embedded substances that will help man combat mosquitoes or at least reduce infestation to the barest minimum.
\n
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitation of the study and Definition of technical terms.
