GIO-TRUJILLO, José Alberto  y  CAMARA-ROMERO, José Luis. Repellent effect of three plant extracs on pests of the crop of Capsicum chinense. Ecosistemas y recur. agropecuarios [online]. 2023, vol.10, n.spe3, e3614.  Epub 26-Ago-2024. ISSN 2007-901X.  https://doi.org/10.19136/era.a10niii.3614.

The objective was to evaluate the repellent effect of ethanolic extracts of Azadirachta indica, Pachyrhizus erosus and Gliricidia sepium, on Capsicum chinense pests. A randomized complete block design was used with three treatments (T1 = A. indica; T2 = P. erosus; T3 = G. sepium) and a control, with 15 plants per treatment. The maceration-infusion method in EtOH was used for the extraction of the treatments. Applying every 7 days at a dose of 15 mL L-1/water. 12 diurnal samplings were carried out with a frequency of seven days. The incidence of 576 pest individuals was recorded, distributed in eight species. The species with the highest incidence was recorded in Bermisia tabaci, Epitrix spp. and Myzus persicae. Treatments T3 and T2 represent the extracts with the lowest incidence of fruit suckers and perforators. The repellent effect of the evaluated extracts will allow the integration of local botanical resources as part of sustainable management of agricultural phytosanitary.
