Rhythms of volatile release from female and male sea buckthorn plants and electrophysiological response of sea buckthorn carpenter moths

Abstract

The sea buckthorn, Hippophae rhamnoides L., is a thorny, nitrogen-fixing, dioecious, and deciduous shrub which has been attacked by a catastrophic outbreak of Holcocerus hippophaecolus in the 'Three North Areas' of China recently. The behavioral responses of female individuals to their dioecious host sea buckthorn, H. rhamnoides ssp. sinensis, were tested by Y-tube bioassay, and intraspecific emission variations and the circadian rhythm of male and female sea buckthorn plants were compared, together with the electrophysiological responses of sea buckthorn carpenter moths to these parameters. Y-tube olfactometry indicated that mated female H. hippophaecolus individuals did not display a significant preference for either sex of sea buckthorns. Additionally, no unique chemical compound was found. Female antennae significantly responded to 1-octene, methyl salicylate, and (Z)-3-Hexen-1-ol acetate, among which methyl salicylate was more abundant in females than in males. In addition, the circadian variation of (Z)-3-Hexen-1-ol acetate suggested that it was an effective compound for host location.

Abundance of active ingredients in sea-buckthorn oil

“…Sea-buckthorn is also known as sandthorn, sallowthorn or seaberry [18]. The plant grows in Europe, Caucasus, Asia Minor and Central Asia, Siberia, China and Tibet [16, 19, 20]. Sea-buckthorn is the most common species in the Hippophae family: H. goniocarpa , H. gyantsensis , H. litangensis , H. neurocarpa , H. rhamnoides L., H. salicifolia , H. tibetana , H. sinensis , which grow from the Atlantic coast of Europe to northwestern Mongolia and northwestern China [20, 21].…”

Sea Buckthorn Oil—A Valuable Source for Cosmeceuticals

“…The only way to obtain the fruit is often to remove the entire branch of the shrub. This is the reason why berries can be harvested only once every two years [1][2][3].…”

“…Sea buckthorn (SB) (Hippophae rhamnoides L.) is a thorny, soil-adhering, deciduous shrub or small tree [1,2]. It is naturally found in Northern and Central Europe, Caucasus, and Asia (Siberia, China, and Tibet).…”

“…[1,3,4]. It is an anti-erosive plant that enhances the soil content since its roots have nitrogen-fixing properties [1][2][3]. In natural habitats, it may reach up to 4 m in height [3].…”

“…Since it has been recognized as a highly valuable plant, SB has been cultivated in different parts of the world, including many countries in Europe, Canada, Russia, and China. [1,3,4]. It is an anti-erosive plant that enhances the soil content since its roots have nitrogen-fixing properties [1][2][3].…”
