Screening of Five Lamiaceae Essential Oils as Repellents for Sweet Potato Weevil, Cylas Formicarius (F.) (Coleoptera: Brentidae)

In this research, the repellent activity of five Lamiaceae essential oils, Agastache rugosa, Elsholtzia blanda, Elsholtzia ciliata, Elsholtzia penduliflora, and Plectranthus ovatus, was evaluated against sweet potato weevil, Cylas formicarius using a two-choice test between the essential oil-treated filter paper and the control. E. blanda and A. rugosa essential oils have some sweet potato weevil attractant properties at low dose (<47.16 nl/cm2),while N,N-diethyl-3-methylbenzamide (DEET), P. ovatus, E. penduliflora, and E.ciliata essential oils have repellent properties at doses ranging from 15.72 nl/cm2 to 196.49 nl/cm2. The effect of type of essential oil and their dose were interactively associated with repellent efficacy. There was a increase in repellent efficacy as the dose increased for all essential oils. The repellent activities of P. ovatus essential oil and E. penduliflora were higher than the others, and the repellent effects of E. ciliata essential oil and DEET were more dose-dependent than others, indicating that at low dose, P. ovatus and E. penduliflora essential oils have stronger repellent efficacy, but at higher dose DEET and E. ciliata have greater effects. Our findings clearly demonstrate that P. ovatus, E. penduliflora, and E. ciliata essential oils are candidate materials for future investigation as repellent compounds against sweet potato weevil control.

<p>The efforts of production enhancement of sweet potato are limited by some constraints including some pest. One of the important pests is sweet potato weevil (Cylas formicarius Fabr.). The use fertilizer and kind of variety are important factors determining the yield of sweet potato. This study aims to examine the effect of manure on three varities of sweet potato and evaluate the yield of varieties test on sweet potato weevil, through choice test and no choice test. The research in field used Randomized Completely Block Design (RAKL) with two treatments. The varieties (Korea, Manohara, Madu) and manure (control, cow manure, chicken manure). Research in laboratory used three varieties and adult of C. formicarius. The result showed that granting of chicken manure on Manohara varieties gave the best response on a length of stem, number of leaves, fresh weight and weight of tubers. Granting of cow manure on Manohara and Madu Varieties give the weight of tuber stricken was less than Korea varieties. Choice test in Manohara varieties show the high population and in no choice test show Korea Varieties had high population of C. formicarius.</p>

Cymbopogon Schoenanthus

The plants of genus Cymbopogon are well known for their use in traditional medicine and for their high content of essential oils that are widely used as flavoring agents, fragrances, cosmetics, and pharmaceuticals. Essential oils isolated from the dried stems and inflorescence of cultivated Cymbopogon schoenanthus (L.) Spreng. (Poaceae) collected from Khartoum state (Sudan) in two periods were studied. The results of chemical analysis of C. schoenanthus revealed that this plant is rich in essential oil which is a valuable source of the commercially important monoterpene, piperitone (47.7-71.5%). Other abundant constituents of the oils were intermedeol (6.1-17.3%), ?-2-carene (4.5-10.0%) and elemol (2.7-9.0%). The essential oil from the inflorescence was tested for spasmolytic activity using three different experimental models: against spontaneous contractions, contractions induced with acetylcholine and contractions induced with potassium chloride. The oil exhibited strong, significant and dose-dependent spasmolytic activity, indicating the possibility for further investigations of this essential oil for its medicinal purposes or application in food industry.
