Methanolic extracts of Isodon rugosus Wall. ex Benth (Labiatae), Boenninghausenia albiflora (Hook.) Rchb. ex Meisn. ( Rutaceae ) , Calotropis procera Aiton (Dryand) ( Apocynaceae ) , Daphne mucronata Royle (Thymelaeaceae), Tagetes minuta L. (Asteraceae), Cinnamomum camphora (L.) J. Presl ( Lauraceae ) and Eucalyptus sideroxylon A. Cunn. ex Woolls ( Myrtaceae ), grown in lower Himalayan regions of Pakistan were evaluated at 2% concentration against Peach fruit fly Bactrocera zonata Saunders, 1842 (Diptera: Tephritidae). Tagetes minuta extract showed maximum of 73% mortality against male fruit flies and in case of female maximum mortality shown by C. camphora and I. rugosus was only 16.6%. Boenninghausenia albiflora extract had maximum repellence of 44.4% followed by 42% by D. mucronata extract and the minimum number of flies were settled on these two plant extracts as compared to the others. The lowest number of pupae 3.3% as collected from guavas treated with T. minuta extract; this was significantly lower than the 62.6% pupae recovered from untreated guavas. The lowest numbers of adults (0.33%) were recovered from guavas treated with T. minuta extract compared to 45.3% adults from untreated guavas. The pupae inhibition was highest (94.6%) for T. minuta extract. Inhibition of adult emergence was highest i.e. 99.2% for T. minuta extract. Tagetes minuta can be exploited as a potent source of pesticide against fruit fly, B. zonata , due to maximum pesticidal potential as compared to all other plant extracts applied. The results are discussed in relation with potential benefits of incorporating plant based insecticides in integrated pest management strategies against B. zonata .
