Fig. 1 in Virulence of two entomopathogenic nematode species, Steinernema sp. (strain PQ16) and Heterorhabditis indica (strain KT3987), to nymphs of the coffee cicada Dundubia nagarasingna

Fig. 1. Mortality of coffee cicada nymphs, Dundubia nagarasingna, treated with entomopathogenic nematodes, Steinernema sp. (strain PQ16) and Heterorhabditis indica (strain KT3987), at inoculation doses of 100, 200, 300, 400, 500 and 600 infective juveniles (IJ) nymph−1 at A: 24 h, B: 48 h, C: 72 h after inoculation. Values are means ± SE; different letters in each figure represent means that are statistically different between nematode concentrations (Tukey's HSDtest, P <0.05). Thecorrectedcumulative mortality axis indicates nymphal mortality increasing with IJ inoculation doses and exposure time. Mortality data were corrected by Abbott's formula (Abbott, 1925).
