Repellent activity of Tanacetum parthenium (L.) and Tanacetum vulgare (L.) essential oils against Leptinotarsa decemlineata (Say)

Abstract

The Colorado potato beetle, Leptinotarsa decemlineata (Say), is one of the most destructive pest species to have developed resistance to most chemical insecticides. We determined the composition and evaluated the potential of Tanacetum parthenium L. and Tanacetum vulgare L. (Asteraceae family) essential oil (EO) application as an alternative eco-friendly control strategy against L. decemlineata. We assessed the antifeedant activity for L. decemlineata larvae and adults by estimating the damage to potato leaves treated with three concentrations of EOs dissolved in ethanol (0.125, 0.25 and 0.5%). Results showed that T. parthenium EO was more effective against larvae, and T. vulgare was more effective against adults. In an olfactometer assay, the time required to choose an untreated leaf disc did not depend on the Tanacetum species, or life stage examined. However, the concentration of EO exhibited a significant effect on the behaviour of both developmental stages. At higher EO concentrations, both third instar larvae and adults require less time to choose an untreated leaf disc. Additionally, T. parthenium EO provoked more rapid movement away from the treated leaf disc than T. vulgare, especially at the highest concentration. Successful modification of L. decemlineata behaviour by the two Tanacetum oils suggests that they possess the potential for use in potato protection.

“…Lazarević et al reported that at higher EO concentrations, both third instar larvae and adult T. parthenium and T. vulgare required less time to choose an untreated leaf disc. Additionally, EO provoked rapid movement away from the treated leaf disc especially at the highest concentration [ 40 ].…”

A Comparison between Bulgarian Tanacetum parthenium Essential Oil from Two Different Locations

“…According to different studies, T. parthenium extracts exhibit anti-nociceptive [13][14][15], antioxidant [13,[16][17][18][19][20][21], antibacterial [22], insecticidal [23], anti-inflammatory, neuromodulatory, antispasmodic, and uterine stimulant activity [24,25]. Investigations on feverfew EO have indicated antimicrobial [26][27][28][29][30][31], antioxidant [32], repellent [33], cytotoxic, and low anti-inflammatory [34] properties. Parthenolide, a sesquiterpene lactone isolated from the plant, has been reported to demonstrate antiinflammatory [35][36][37][38][39][40][41][42][43][44][45], neuroprotective [46,47], cholesterol-lowering [48], antiviral [49], antileishmanial [50], and antitumor [51][52][53][54][55][56][57] effects.…”
