Combined action of Derris indica Bennet either with a bacterium or with an insect growth regulator on mature larvae of Alphitobius diaperinus Panzer (Coleoptera: Enebrionidae)
Combined action of Derris indica Bennet either with a bacterium or with an insect growth regulator on mature larvae of Alphitobius diaperinus Panzer (Coleoptera: Enebrionidae)
The combined action of D. indica either with Bacillus thuringiensis var. kurstaki (Btk; at 25, 50, 100, 150, 200 and 300 ppm) or with triflumuron (0.125, 0.25, 1.25, 2.5, 3.75 and 5 ppm) on the mature larvae of A. diaperinus was investigated. Results showed that the efficacy of Btk was lower than that of triflumuron, the LD50 values being 131.372 and 8.618 ppm respectively.
