Leaf hopper, Amrasca biguttula biguttula, and whitefly, Bemisia tabaci are the most economical sucking pests of cotton (Gossypium spp.) causing stunting, shortening of internodes and transmitting plant pathogenic viruses. The management of these pests is primarily based on application of synthetic pesticides, which not only triggers resistance to insecticide molecules but also contributes to environmental pollution. We aimed to study the attraction of A. biguttula and B. tabaci toward six natural essential oils (NEOs) viz., sandalwood, basil, grapefruit, rose, clove and mint oils using yellow sticky traps under field conditions. The results showed that traps treated with sandalwood and basil oils attract significant numbers of A. biguttula and B. tabaci as compared to the other traps during the seasons 2016-2017 and 2017-2018. Further, the Attractive Index (AI) of sandalwood and basil oils to these pests were significantly higher (i.e., >1). In addition, the traps treated with sandalwood and basil oils caught relatively lower numbers of natural enemies. The GC-MS analysis specified the presence of vital attractive volatile compounds, viz., santalene, funebrene and pentadecane in sandalwood; and linalool, β-farnesene, caryophyllene and methyl eugenol in basil oil. Based on the results obtained it can be concluded that application of sandalwood and basil oils increased the attracting efficacy of sticky traps for the management of A. biguttula and B. tabaci in cotton.
