Abstract

Under the current agricultural model, pesticides are almost indispensable for providing sufficient food for the global population. However, there are alternatives such as the use of plant essences oils that help reduce the concerns raised by this chemical control as the resurgence of new pests, impact on non-target species and increase in cases of resistance of pests in stored grain. Thus, the objective of the research was to analyze in the laboratory the biocidal and repellent activity of the essential oil of the master, Ageratum conyzoide L. (Asteraceae), on the adult of Zabrotes subfasciatus (Boheman, 1833) (Coleoptera: Chrysomelidae: Bruchinae). Lethal and sublethal concentrations were estimated by Probit analysis for contact and repellent effect. In patch testing the lethal concentration to kill 95% (LC95) and 50% (LC50) Z. subfasciatus population were 6.697 uL / 40g grains and 3.414 ul / 40g grain, respectively. In the repellency test, the concentrations used were based on the contact test results, with the concentrations: 0.24; 0.76; 1.67 and 2.41; 2.59 and 3.41 μL a neutral effect. Thus, essential oils of the stepfather plant have high biocidal activity, which allows us to redesign the current world production systems.
