| Sumario: | This study was conducted to evaluate the potency of aqueous A. indica leaf powder extract (LPWE) against A. tubercularis infesting mango. Field experiments were conducted in Ethiopia at two experimental sites, western Oromia. Randomized Complete Block design was laid in four replications with four blocks consisting of sixteen treatment plots. The treatments were 0.05, 0.1 and 0.15 mg/ml spray concentrations made from A. indica LPWE. The treatments were applied 3 times at 10-day interval and the mortality count was carried out 10 days after 1st, 2nd and 3rd treatment applications. The results of the study confirmed that among the tested three different concentration of A. indica LPWE 0.15 mg/ml concentration significantly (p < 0.05) reduced the population of sessile A. tubercularis at both experimental sites. The results also indicated that male adults and nymphs were more affected than females. The population of sessile A. tubercularis significantly decreased as the concentration of A. indica LPWE increased in comparison with the check plots. Thus, the use of A. indica LPWE at high concentrations led to a notable population reduction of sessile A. tubercularis and its effects. Hence, the use of A. indica LPWE can be recommended for A. tubercularis management as part of integrated pest management. |
