Evaluation of synergism / antagonism in the efficacy of entomopathogenic fungi against selected mealybugs through co-administration with some adjuvants under both laboratory and pot conditions

Rajesh Illathur, R Philip Sridhar and JS Kennedy

Mealybugs (Hemiptera: Pseudococcidae) are important insect pests in worldwide. Forty one different treatments were tested against Phenacoccus solenopsis in laboratory. Among the treatments, lemongrass oil in combination with Lecanicillium lecanii (Zimm.) Zare & W. Gams (LlMO2) recorded the highest mortality of 93.10 per cent at 7 DAT, followed by citronella oil in combination with L. lecanii (LlMO2) showed the mortality of 89.65 per cent at 7 DAT. As per the results obtained, lemongrass oil, citronella oil, neem oil, pungam oil, mustard oil, sweet flag oil and castor soap shows synergistic effect with L. lecanii against meaybugs.
