Parasitismo de billaea claripalpis sobre larvas de diatraea saccharalis en condiciones de campo

The main purpose of this research is find out the parasitism of gravid and non-gravid females of Billaea claripalpis larvaes of Diatraea saccharalis in sugarcane fields. At viru valley we can observed the treatments has the highest parasitism were T1: release of non-gravid B. claripalpis females at a dose of 40 pairs/ha and T2: release of gravid B. claripalpis females at a dose of 50 pairs/ha, with 57.56% and 57.94% respectively, likewise, the lowest parasitism occurred in T3: release of gravid B. claripalpis females at a dose of 40 pairs/ha with 50.93%. In desert conditions in the Alto Salaverry area, T1: release of non-gravid females of B. claripalpis at a dose of 60 pairs/ha, obtained the highest parasitism with 51%. Also, the treatments that obtained the least parasitism were T2: release of gravid females of B. claripalpis at a dose of 80 pairs/ha and T3: release of gravid females of B. claripalpis at a dose of 60 pairs/ha, with 32.01% and 37.66% respectively. In the linear regression tests, r = -0.81 and R2 = 0.8535, show a negative correlation.
