Abstract

VALDES HERRERA, Roberto et al. Myrtaceae species, an alternative for the control of Sitophilus oryzae. Ctro. Agr. [online]. 2020, vol.47, suppl.1, pp. 54-58.  Epub Dec 17, 2020. ISSN 0253-5785.

The experiments were conducted at the Center for Agricultural Research (CIAP) to demonstrate the allelopathic effect exerted by extracts of eight species belonging to the Myrtaceae family on Sitophilus oryzae L. The increase of insects in the mixtures of the grain with powders of the botanical species was calculated. Seven Myrtaceae species exerted an insectistatic effect on S. oryzae. The extracts of the botanical species Pimenta racemosa (Mill.) J.W. Moore also had an insecticidal effect. In the treatments with extracts of Syzygium malaccense L., P. racemosa and Piper auritum Kunth, the insect did not multiply.

Keywords : allelopathic effect; rice weevil; Myrtaceae.
