Malaria is one of the commonest and major parasitic infections of public health interest in the globe especially in the tropics and sub-tropics. It still remains the principal cause of morbidity and mortality in all sub-saharan countries up to this day. Malaria accounts for 10% - 30% of all hospital admissions, and is responsible for 15% - 25% of all deaths in children under the age of 5 years. Pregnant women are not be exonerated from the risk of malaria infections as the disease is also said to be responsible for a substantial number of miscarriages and underweight births (WHO, 1996; RMB, 2007). Globally, only mosquitoes of the genus Anopheles have been incriminated as the vectors of this life-threatening disease. Therefore the control of malaria invariably implies sustainable control of its vectors.

One of the best control measures is the application of intervention methods. Such intervention methods involve the use of insecticides, larvicides, topical repellents among others, to intercept the vector-host interactions or contact. Cutting off or breaking the link between mosquito vectors and human hosts consequently disrupts the life cycle of malaria parasite. The overall result is the reduction in morbidity and mortality rates following reduced transmission of the disease (Toure, 2002). Beside from the use of insecticide treated nets (ITNS), many other different types of substances, natural and synthetic, have been discovered and adopted to protect human hosts against mosquito bites. These substances keep mosquitoes from biting humans and make human hosts undetectable, or are anti-mosquito cloak that conceal or hide the host from recognition by mosquitoes, as a meal source (Jacobson, 1990; Foster and Duke, 1990; ICMR, 2003). Today citrus essential oils as well as extracts from other plants such as Cedar wood, Citronella, Eucalyptus, Pennyxoyai, Turpentine, Winter green (Sadik, 1973), have been identified as very important natural resource of either pesticides or insecticides (Raguraman and Singh, 1997; Gbolade, 2001), or repellent (Sadik, 1973; Thorsell et al., 1998; Oyedele et al., 2000; Govere et al., 2000; Girgenti and Suss, 2003). They have been used as both topical preparations and combustible products like incense sticks to repel insects such as mosquitoes.

 In some places, dried citrus fruit peels are burnt on charcoal fire to repel and/or destroy mosquitoes in homes.The global preference of phytochemicals in malaria vector control may be based on their unique properties which include environmental sustainability, easily biodegradable, readily available and cheap andnon-toxicity to man and his domestic animals (Herrera and Vieto, 1980; Duke, 1992). Repellent and attractant properties of phytochemicals from plants other than citrus plant species have been investigated by various scholars (Tyagi et al., 1994; Ansari and Razdam, 1995; Trigg, 1996; Pathak et al., 2000; Moore et al., 2002).

Mosquitoe insecticides are quick and powerful way to get rid of mosquitoes but unfortunately they are only temporary. The effect usually lasts only as long as the insecticide is present, as soon as it drift away or dries out, the mosquitoes are back. Mosquitoes control officials use insecticides only in combination with other form of mosquito control. The same method should apply to use around the house. Insecticides are not long-term solution. Insecticides are commonly dispersed through a fog or ultralow volume mist. Insecticides are available at most home and garden stores, and it come in hand- held applicator or devices that can be attached to a lawn mower. Example of two popular insecticides are Malathion and Permethrin.

Malathion is an organophosphate often used to treat crops against a wide array of insects. It can be sprayed directly onto vegetation such as bushes where mosquitoes like to rest, or used in a 5% solution to fog in the yard. In small amount used for mosquito control , it poses no threat to humans or wide life. In fact, Malathion is also used to kill headlice.

Permethrin is one of the group of chemicals called Pyrethroids. It is a synthetic form of a natural insecticides found in Chrysanthemus flowers. It usually mixed with oil or water and applied as a mist about 1/100th of a pond per acre. Like Marathion, permethrin kills mosquitoes by disrupting their nervous systems. Not harmful to humans and animals in small quantity, but toxic to fishes and bees.

Both Malathion and permethrin are also available in sprays for use inside the home. The insecticides works for several days when applied to shrubbery or grass, but will breakdown overtime, especially in rain. When released into air through fog or mist. They are usually good for few hours before they become too dissipated to be effective.


Over the years, mosquitoes pose a great threat to humans' health. So, need arise to develop a lasting solution to the invasion of mosquitoes in our environment. Different methods had been detected to control mosquitoes but there is need to develop a cheap, easy to produce, and long lasting solution.


The main objectives of the study is the production of mosquito repellant insecticides using plant extracts which will be cheap, effective and readily available for everyone even in rural area.


1. What is an insecticides?

2. What is the effect of plants extract on mosquito?

3. Is mosquito repellant insecticides a lasting solution to mosquito invasion?


Overtime and repeated use of insecticides resistance can occur in mosquito population. Scientists researching the subject believe that the ability of mosquitoes to resist insecticides represent a serious threat to the prevention of diseases such as Malaria, dengue, Chikunginya. This threaten effort to prevent epidermis.

Mosquitoes can be reduced or controlled around our homes naturally through the use of natural or biological means. Predatory fish (Gambusia), Dragonflies, plant repellant, bacteria and even other mosquitoes that are mosquito eaters. Citrosa, Lemon thyme, and Rosemary plants are known to be good  insect repellant. Bacillus Thurigiesis Israelensis is a Natural occurring bacteria used as a larvacide in ponds and other areas where mosquitoes are breeding. These are poisonous to mosquito larvae when they feed on it in the water. Mosquito trap are also good method of controlling mosquitoes on our area.Orange peel also known as Cestrum is a wonderful hybrid derived from Cestrum diurnum and Cestrum Nocturnum. Cestrum is a veritable living bouquet of pure orange blossoms that strives well in warm climates. Orange peel is a fragrant orange flower, it need low maintenance and strives in hot weather. Orange peel contains oil known as Limonene oil which has a lethal effect on mosquito and some other insects. Hence, Cestrum can be used as an active ingredient to produce mosquito coil, which when ignited will repel mosquitoes within the limit of the smoke.

How To Write Chapter Three Of Your Research Project (Research Methodology)

  • Methodology In Research Paper

    Chapter three of the research project or the research methodology is another significant part of the research project writing. In developing the chapter three of the research project, you state the purpose of research, research method you wish to adopt, the instruments to be used, where you will collect your data, types of data collection, and how you collected it.

    This chapter explains the different methods to be used in the research project. Here you mention the procedures and strategies you will employ in the study such as research design, study design in research, research area (area of the study), the population of the study, etc. You also tell the reader your research design methods, why you chose a particular method, method of analysis, how you planned to analyze your data.

    Your methodology should be written in a simple language such that other researchers can follow the method and arrive at the same conclusion or findings.

    You can choose a survey design when you want to survey a particular location or behavior by administering instruments such as structured questionnaires, interviews, or experimental; if you intend manipulating some variables.

    The purpose of chapter three (research methodology) is to give an experienced investigator enough information to replicate the study. Some supervisors do not understand this and require students to write what is in effect, a textbook.

    A research design is used to structure the research and to show how all of the major parts of the research project, including the sample, measures, and methods of assignment, work together to address the central research questions in the study. The chapter three should begin with a paragraph reiterating the purpose of research. It is very important that before choosing design methods try and ask yourself the following questions: Will I generate enough information that will help me to solve the research problem by adopting this method?

    Method vs Methodology

    I think the most appropriate in methods versus methodology is to think in terms of their inter-connectedness and relationship between both. You should not beging thinking so much about research methods without thinking of developing a research methodology.

    Metodologia or methodology is the consideration of your research objectives and the most effective method and approach to meet those objectives. That is to say that methodology in research paper is the first step in planning a research project work.

    Design Methodology: Methodological Approach

    Example of methodology in research paper, you are attempting to identify the influence of personality on a road accident, you may wish to look at different personality types, you may also look at accident records from the FRSC, you may also wish to look at the personality of drivers that are accident victims, once you adopt this method, you are already doing a survey, and that becomes your metodologia or methodology.

    Your methodology should aim to provide you with the information to allow you to come to some conclusions about the personalities that are susceptible to a road accident or those personality types that are likely to have a road accident.

    The following subjects may or may not be in the order required by a particular institution of higher education, but all of the subjects constitute a defensible in metodologia or methodology chapter.
