Plodia interpunctella (Lepidoptera: Pyralidae): Intoxication with essential oils isolated from Lippia turbinata (Griseb.) and analysis of neuropeptides and neuropeptide receptors, putative targets for pest control

Abstract

The Indian meal moth Plodia interpunctella is a pest of stored products worldwide. Plant-derived essential oils with insecticidal activity could be safe products to control this species. The scarce information about the mode of action of most plant-derived products limits their use for the control of insect pests. Here, we demonstrate that an essential oil distilled from Lippia turbinata ("poleo") has insecticidal activity on P. interpunctella larvae. Furthermore, we performed a comprehensive characterization of P. interpunctella neuroendocrine system, in comparison with other lepidopteran species.

Insecticidal and repellent effects of the essential oils obtained from Argentine aromatic flora

“…The EO caused mortality in larvae in a dosedependent manner, with an LC 50 value of 432.9 mg/L. Furthermore, the EO caused a delay in the pupation day in the surviving larvae, which was correlated with a low expression of the neuropeptides responsible for regulating the postembryonic development in lepidopterans (Corzo et al, 2020).…”

“…The moth Plodia interpunctella is a major economic insect pest of stored products and processed food commodities found worldwide. Corzo et al (2020) evaluated the insecticidal activity of L. turbinata EO in P. interpunctella third-instar larvae. The EO caused mortality in larvae in a dosedependent manner, with an LC 50 value of 432.9 mg/L.…”

Taxonomic Description, Distribution, and Control Measures of Plodia interpunctella (Hübner, 1813) in Kashmir Valley, India

“…Corzo (2020) demonstrated that the essential oil from Lippia turbinata, known as "poleo," has been shown to have an insecticidal effect on P. interpunctella larvae [39]. In addition, they thoroughly characterized the neuroendocrine system of P. interpunctella in contrast to other lepidopteran species.…”

Controlling Stored Products’ Pests with Plant Secondary Metabolites: A Review

“…This formulation can increase the insecticidal efficacy of EO twofold [192]. The essential oil distilled from Lippia turbinata ("poleo") was insecticidal on P. interpunctella larvae [198]. In a recent study, the essential oils (O. vulgare, P. anisum and Tanacetum cinerariifolium) and four plant extracts (Agastache rugosa, Capsicum annuum, C. reticulata and Ginkgo biloba) were proven to be repellent against P. interpunctella.…”
