Table 2 Densities of Nesidiocoris tenuis nymphs and periods needed to control the entire population of Bemisia tabaci according to doses

From: Effect of the native strain of the predator Nesidiocoris tenuis Reuter and the entomopathogenic fungi Beauveria bassiana and Lecanicillium muscarium against Bemisia tabaci (Genn.) under greenhouse conditions in Tunisia

Efficacy of N. tenuis against B. tabaci nymphs Linear equation Y1= 43.43 X1 + 87.80 Y1 = 83.13 X1 + 51.71 Y1 = 7.78 X1+ 85.18 Y1 = 6.92 X1 + 83.09
Coefficient of determination R2 = 0.7947 R2 = 0.8083 R2 = 0.7524 R2 = 0.7459
Density of N. tenuis reduces 100% of nymphs 0.28 0.58 1.9 2.44
Efficacy of N. tenuis against B. tabaci nymphs as a function of time Linear equation Y2 = 0.8543 X2+ 87.6 Y2 = 0.7875 X2 + 88.348 Y2 = 0.8702 X2 + 87.454 Y2 = 0.8638 X2 + 87.636
Coefficient of determination R2 = 0.756 R2 = 0.7885 R2 = 0.6455 R2 = 0.853
Time required to reduce the B. tabaci population by 100% (Weeks) 14.51 14.79 14.41 14.31
