The aphid Myzus persicae (Sulzer) and Aphis gossypii (Clover) (Hemiptera: Aphidiae) are considered to be the most significant arthropod pests affecting greenhouse pepper crops in Argentina as a result of their frequent presence and the seriousness of the damage caused by feeding on phloem and conveying virus, mainly on horticultural crops. Since the integrated pest management is currently an alternative strategy based on ecological practices, the objective of this research was to determine the effectiveness of a variety of botanical products to control aphids in greenhouse pepper crops in Concordia, Argentina. Thus, four bio-rational pest control formulations were tested, namely: (1) neem essential oil (EO), cinnamon EO, clove EO and oregano EO and copete EO (Formulation 1); (2) garlic EO and cinnamon EO (Formulation 2); (3) garlic PE and ruda PE (Formulation 3); 4) adjuvant lecithin soybean and, finally, (4) control (water spray method). For this research, the distribution pattern of plants was carried out according to a completely randomized design replicated 3 times. The variety of treatments was applied by means of a backpack sprayer straight to the foliage on a weekly basis until the end of this trial. Subsequently, the total average number of aphids on every leaf was recorded. The results showed that the treatment with Formulation 1 and Formulation 3 recorded a lower number of aphids compared to the other treatments. However, the highest number of parasitized aphids (mummies) was found on leaves treated with water and lecithin.
