LEYVA SILVA, Maureen Isabel et al. Insecticidal activity of essential oils against Blatella germanica (Linneaus, 1767) (Dictyoptera: Blattellidae). Rev Cubana Med Trop [online]. 2022, vol.74, n.2  Epub 01-Nov-2022. ISSN 1561-3054.

Blattella germanica (Linneaus, 1767) is a cockroach species considered a public health pest, since it is associated with a great number of disease-causing microorganisms in humans. For its control, different types of synthetic-based insecticidal formulations are used, to which it is mostly resistant. In this context, there is a growing interest in botanical insecticides. In this research, oils from Citrus aurantium (L., 1753), Ocimum basilicum (L., 1753), Piper aduncum subsp. ossanum (C.DC. Saralegui), and Eucalyptus globulus (Labill, 1800) were evaluated by topical application of 1 µL to the first abdominal sternum of the individuals. The four essential oils evaluated showed insecticidal activity against adult B. germanica with LC50 ranging from 58µg/µL for O. basilicum to 250µg/µL for P. aduncum.
