The field efficacy of Beauveria bassiana in comparison with the commercial formulation of B. bassiana (Daman) and standard check malathion 50 EC against Hydaphis coriandri and Aphis craccivora showed significant variations among pre-treatment and post-treatment counts. H coriandri, one day after treatment (DAT) a significant reduction (70.22%) in the aphid population was observed in malathion 50 EC (0.05%) followed by Daman (15.22%). At 7 DAT, the highest population reduction was 92.81% in malathion 50 EC followed by Daman (83.41%) was recorded, whereas in A.craccivora one-DAT, a significant reduction (68.42%) in the aphid population was observed in malathion 50 EC (0.05%) followed by Daman (10.70%). At 7 DAT, the highest population reduction was 90.0% in malathion 50 EC followed by Daman 81.34% were observed. Daman showed significantly high percent of reduction (54.60%) and (47.35%) in H coriandri and A.craccivora, respectively. However, the standard check, malathion 50 EC were highly toxic and showed significantly high percentage reduction (84.85%) and (82.55%) in the both the aphids population.Keywords

Laboratory bioassays were carried with seven different concentrations of Beauveria bassiana against Hyadaphis coriandri by using detached leaf bioassay technique with slight modifications. The mortality in treated aphids increased in conidial spore concentration. The highest concentration (1x1010 conidia ml-1) caused maximum cumulative mortality (96.85%) at 7 days after treatment compared to the lowest concentration (1×104 conidia ml-1) with 67.61 per cent mortality. The median lethal concentration (LC50) value recorded with B. bassiana was 1.5x104 conidia ml-1 in mixed H. coriandri population. Median lethal time (LT50) values were found to be inversely proportional to the spore concentration of B. bassiana and were observed as 45.70, 67.60, 71.30, 87.04, 97.72, 120.26 and 141.57 h for 1010, 109, 108, 107, 106, 105, 104 conidia ml-1, respectively.Keywords
