Impact of Spodoptera frugiperda (Lepidoptera: Noctuidae), on maize yield in humid tropical zones of Central Africa.

The fall armyworm damage incidence in the untreated was very highly significant (LR χ 2 = 17.17; df = 1; P < 0.001—LR χ 2 = 7.68; df = 1; P = 0.005), significant (LR χ 2 = 6.53; df = 1; P = 0.011—LR χ 2 = 4.04; df = 1; P = 0.044), or similar (LR χ 2 = 2.42; df = 1; P = 0.119—LR χ 2 = 0.277; df = 1; P = 0.599) to treated plots in 50.00%, 12.50%, or 37.50% of the cases, respectively when the data where considered per sites and the sampling dates.
