Studies in the agricultural market area show that although chemical-dependent agriculture has made up the
majority of areas worldwide over the past 15 years, there is a disproportionate need for alternative residue-free food webs
and ecological production for new markets. Residue is a major problem especially in the export of agricultural products in
our country. The low residue threshold of the exporting countries and the unhealthy acceptance of these products cause
significant economic losses in terms of both domestic and foreign markets. Therefore, it is very important to produce residuefree
products and export them. Bio-pesticides are biological preparations with zero residue efficiency and their prevalence
is being tried to be increased all over the world.In the fight against insects, environmentally friendly, sustainable agents with
new and different mechanisms of action should be developed. In the last decade, the demand for natural biological actives,
namely bio-pesticides, which are seen as an alternative strategy to biodegradable pesticides that can be used in integrated
control programs and have appropriate potential, has been increasing intensively.For these reasons, plant-based pesticides
attract attention due to their environmental friendliness, compliance with integrated control approaches, and their GRAS
(Generally Regarded as Safe) status in terms of both the environment and human health. On the other hand, D-limonene
(1-methyl-4-(1-methylethenyl) cyclohexane) is one of the most common natural monocyclic monoterpenes. It contains the
highest amount of citrus varieties (orange, lemon mandarin, laym and goldentop), especially in fruit peels, and has a lemonlike
odor. D-limonene is accepted as a recyclable, sustainable natural ingredient with GRAS (Code of Federal Regulations as
generally recognized as safe) status, which is accepted as safe for human health, environment and ecological sense. It has also
been determined that D-limonene has antimicrobial, antifungal and antibacterial effects on many fungal species and some
bacterial species. In this study, orange peel essential oil was extracted and its content was analyzed to determine the possible
use of orange peel essential oil as a bio-pesticide. Orange peel essential oil was extracted from orange peels by the Soxhlet
method. The yield of D-Limonene was recorded as 9.46%.
