The hexane extracts of scales of male and females of Earias vitella F. and Corcyra chephalonica Stainton were evaluated along with standard octacosane on the performance of Trichogramma chilonis under laboratory conditions and potted plants. Results revealed that eggs of C. cephalonica treated with hexane extract of female E. vitella and C. cephalonica scales at 10000 ppm resulted in maximum parasitism of 81.99% and 75.99% by T. chilonis, respectively, as against 40.66% in untreated (only hexane). Maximum emergence of 71.03% was observed in eggs treated with female extracts of C. cephalonica female followed by E. vitella (70.08%). Similar was the trend with fecundity and longevity with extract of female C. cephalonica. The effect of kairomones on parasitism evaluated with potted plants revealed significantly more parasitism when stapled egg cards of C. cephalonica on cotton and pigeonpea were treated with extract of female E. vitella scales (66.66 and 70.05%, respectively).
