Chemical constituents and insecticidal activities of the essential oil from Alpinia blepharocalyx rhizomes against Lasioderma serricorne

Abstract

The aim of this research was to determine the chemical constituents and toxicities of the essential oil derived from Alpinia blepharocalyx rhizomes against the cigarette beetle, Lasioderma serricorne (Fabricius). The essential oil of A. blepharocalyx rhizomes was obtained by hydrodistillation and was investigated by gas chromatography-mass spectrometry (GC-MS). A total of 46 components of the essential oil of A. blepharocalyx rhizomes were identified. The principal compounds in A. blepharocalyx essential oil were camphor (23.13 %), sabinene (11.27 %), α-pinene (9.81 %) and eucalyptol (8.86 %) followed by camphene (8.05 %), sylvestrene (5.61 %) and α-phellandrene (5.00 %). Among them, the four active constituents, predicted with a bioactivity-test, were isolated and identified as camphor, sabinene, α-pinene and eucalyptol. The essential oil of A. blepharocalyx possessed strong contact toxicity against the cigarette beetle with ad LD 50 value of 15.02 μg adult -1 , and exhibited strong fumigant toxicity against L. serricorne adults with an LC 50 value of 3.83 mg L -1 air. The results indicate that the essential oil of A. blepharocalyx shows potential in terms of contact and fumigant toxicities against stored product insects.

Chemical Composition and Insecticidal Activity of Essential Oils from Zanthoxylum dissitum Leaves and Roots against Three Species of Storage Pests

“…dissitum roots exhibited stronger contact toxicity against L. serricorne , e.g., essential oils of Litsea cubeba (LD 50 = 27.3 μg/adult) [22], Cinnamomum camphora (LD 50 = 21.3 μg/adult) [23], Myristica fragrans (LD 50 = 19.3 μg/adult) [7]. The essential oil showed similar contact toxicity to the essential oils of Alpinia blepharocalyx (LD 50 = 15.0 μg/adult) and Artemisia stolonifera (LD 50 = 12.7 μg/adult) [24,25]. Meanwhile, the essential oil of Z .…”

An overview of the chemical composition and biological activities of essential oils fromAlpiniagenus (Zingiberaceae)

“… 3 A. blepharocalyx is a pseudostem, reaching a height of up to 3 meters and used as a flavor and fragrance. 123 In Chinese traditional medicine, A. blepharocalyx rhizomes are used to treat abdominal pain and abdominal distension. 123 The juice obtained from the fruits, rhizomes and seeds of this plant has been used as Vietnamese traditional remedies to cure stomachache digestive disorders and abdominal aches due to the cold.…”

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

“…It can have up to four generations per year and it overwinters as larvae. Extracts of the botanical species O. acutidens seemed to be the most effective in terms of fumigant activities against this pest [124], followed by Artemisia mongolica [81], Alpinia blepharocalyx [50] and Perilla frutescens [127]. P. frutescens (L.) [127], Z. planispinum [127] and Artemisia stolonifera [59] extracts and ingredient components were also very promising as alternative and greener fumigants.…”

“…For the most part, the references on plant extracts used to combat P. interpunctella report on essential oils. In this context, when the fumigant toxicity of the C. copticum EO was assessed against growth stages of P. interpunctella, it was concluded that the adults were about 500 times (LC 50 [226]. In a choice test of P. interpunctella using an olfactometer, the strongest repellency was exhibited by the essential oil of A. graveolens (100%), Thymus vulgaris (100%) and R. officinalis L. (93.33%) and the weakest repellency by Hyossopus officinalis (7.69%) and P. sativum (9.48%) [152].…”
