Repellent Effect of Herb Extracts on the Population of Wingless Green Peach Aphid, Myzus persicae Sulzer (Hemiptera: Aphididae)

Abstract

Investigation of the repellent and insecticidal effects of 8 kinds of herb extracts (chives, dokudami, eucalyptus, lavender, peppermint, cherry sage, sweet pepper and tansy) against wingless green peach aphids were conducted in laboratory and field test.In laboratory repellent tests, 20 aphids were placed between a radish leaf and filter paper for 16 h and aphids on radish leaf were calculated. In laboratory insecticide tests, 20 aphids were placed on a radish leaf treated with herb extract, and live aphids were counted after 16 h. In field tests, the number of aphids that propagated on radish leaves treated with each herb extract was assessed every 3 days.In the laboratory, dokudami, tansy and sweet pepper extracts repelled aphids, while chives, sweet pepper and tansy extracts killed them. In particular, sweet pepper and tansy extracts proved to be a potent insecticide against aphids.In the field test, the results found that extracts from dokudami, cherry sage and lavender had repellent effect on aphids. In particular, dokudami extract was a highly effective repellent against aphids. These findings suggest that dokudami extract can be used to control wingless green peach aphids in the field.

Repellence of Myzus persicae (Sulzer): evidence of two modes of action of volatiles from selected living aromatic plants

“…Nana only acted on their olfactory orientation in the presence of or via the host plant ( C. annuum ). Contrary to other studies, our findings demonstrated that none of the headspace volatiles from L. latifolia , M. piperita or R. officinalis plants exhibited significant negative effects against M. persicae . Differences between results were probably related to qualitative (presence/absence of specific VOCs) and quantitative variations among the chemical composition of volatiles perceived by aphids .…”

“…VOCs from rosemary ( Rosmarinus officinalis L.) plants are effective as a good aphid repellent . Similar properties have been reported for volatiles from lavender ( Lavandula latifolia L.) and peppermint ( Mentha piperita L.) …”

“…Contrary to other studies, our findings demonstrated that none of the headspace volatiles from L. latifolia, M. piperita or R. officinalis plants exhibited significant negative effects against M. persicae. 9,10,[13][14][15][16] Differences between results were probably related to qualitative (presence/absence of specific VOCs) and quantitative variations among the chemical composition of volatiles perceived by aphids. 18 Variations in volatile profiles of the same plant species can be related to genetic differences and to various biotic and abiotic factors linked to plant nutritional status, stress conditions, and phenological stages.…”

“…9,13 Similar properties have been reported for volatiles from lavender (Lavandula latifolia L.) and peppermint (Mentha piperita L.). 9,[14][15][16] Scientists have put great effort into understanding CP volatile effects on pests. The properties of plant VOCs against aphids, such us repellency, have been frequently discussed in previous studies.…”

Effect of Water Extract From Mint on Selected Crop Pests Feeding and Survival

“…The studies so far indicate the effectiveness of peppermint extracts in certain aphid species combating, e.g. peach-potato aphid (Myzus persicae Sulzer) [Ikeura et al 2012]. In turn, the essential oils of peppermint were tested for toxicity against mosquitoes, as reported by Ansari et al [2000] and Kumar et al [2012].…”
