  The present experiment was conducted to evaluate the tritrophic effect of Metarhizium anisopliae on wheat aphids and its parasitoids. The experiment consisted of ten treatments having seven concentrations (1 ppm, 2 ppm, 4 ppm, 8 ppm, 16 ppm, 32 ppm and 64 ppm) of M. anisopliae and field recommended doses of confidor (Imidacloprid) + Hombre (Febuconazole + Imidacloprid) and control. No aphid infestation was observed during the 1st week of December to the 2nd week of the February. 1.5 aphids/tiller were observed where Hombre, Confidor and M. anisopliae at the rate of 64 ppm, 32 ppm and 16 ppm were applied. Maximum aphid population (10.5/tiller) was observed in the control area than the treated plots. M. anisopliae application at the rate of 1 ppm, 2 ppm, 4 ppm and 8 ppm demonstrated 64.0%, 64.50%, 64.55% and 64.51% percent adult emergence of aphids. Seed treatment method was found statistically more effective (3.8 aphids/tiller) than root dip method (3.0 aphid/tiller).
