Plant essential oils have long been recognized as an important natural source of pesticides and repellants. Their wide distribution in nature and their biological capacity allows them to be considered for both industrial and home use against pest control. The different activities of the human being are affected by pathogens such as fungi, bacteria, viruses and insects, the latter being the ones that most influence agricultural production and health. Much of the research has focused on the use of synthetic products that have characteristics of repellency and elimination of pathogenic species and the problems they cause in the environment and the health of those who produce it, apply it and finally consume it. When carrying out a treatment or application of organic products such as essential oils in this case, these can have positive as well as negative effects, the research shows that when making a comparison of the essential oils present in plants, it will have a dependence on the dose that is applied for which the study would help in the control of different pests that greatly affect the plantations, the doses of these will depend on the percentage of purity of the oil and can range from five to thirty five per cent varying likewise its mortality rate up to ninety five per cent as occurs in the case of lemon that has sixty per cent limonene.
