Study of bioinsecticidal activity of linalool derivative.

The aim of this study was to evaluate the insecticidal properties of a linalool derivative against Eurygaster integriceps and Eurygaster maura, the main pest insects of cereal crops. We investigated the insecticidal properties of a linalool derivative as an analog of a synthetic plant-based insecticide.

Plants such as Coriandrum sativum L., Apiaceae, Juniperus, and Artemisia annua are rich sources of compounds with insecticidal activity. Plants accumulate various metabolites that can play a protective role against pest insects and other plant-feeding organisms.

Linalool, a plant-derived monoterpene alcohol, is a promising compound with a variety of uses. Linalool indicating its potential usage in the control of pathogens and growing pest insects has proven antimicrobial and insecticidal properties.

Linalool was isolated from Coriandrum sativum L., Apiaceae seeds, modified into linalyl monomethyl succinate. In conditions of Coriandrum sativum L., Apiaceae hydrodistillation, an essential oil were yielded with a high up to 75% consisting of linalool. After we obtained a derivative of linalool as linalyl monomethyl succinate.

Modified linalool, as linalyl monomethyl succinate, tested for contact toxicity on insects of Eurygaster integriceps and Eurygaster maura. An aqueous solution of linalyl monomethyl succinate caused effective and rapid 100% mortality in insects within the first three days of the test period when applied topically. The testing linalyl monomethyl succinate solution possessed toxic properties and altered insect behavior to varying degrees, depending on its concentration.

Our experiments of plant-based compound insecto-toxicity are ongoing.
