Studies on biological control of Pigeonpea Pod Borers in India
Anzeiger für Schädlingskunde, Pflanzenschutz, Umweltschutz 67 (5), 103-106
Abstract: Results of two field experiments, one on SA 1 pigeonpea in rainfed and the other on Co.5 pigeonpea in irrigated conditions revealed that Bacillus thuringiensis var.kurstaki (B.t.k.) (Delfin), its combinations with nuclear polyhedrosis virus of Heliothis armigera and Chrysoperla carnea were as effective as endosulfan in reducing the pod borers, Heliothis armigera and Exelastis atomosa. However, B.t.k. 1.25 kg+endosulfan 175 g/ha or B.t.k. 2.5 kg+HaNPV, 250 LE/ha gave better control of damage to flowers and pods than B.t.k. applied alone on SA 1 pigeonpea. The yield differences between these treatments were not significant. A combination of HaNPV 250 LE/ha+endosulfan 175 g/ha was superior to B.t.k. Similar trend was seen on Co.5 pigeonpea. Release of C. carnea second instar larvae 1 lakh/ha was not effective in increasing the yield of pigeonpea.
