Resumo: | In this study, we aimed to determine the spatial distribution of Quesada gigas (Hemiptera: Cicadidae) nymphs in parica (Schizolobium parahyba var. amazonicum, Fabaceae) plantations, as well as their most commonly found stages of development and gallery depths in the soil. Two plots were selected according to damage intensity – greater or smaller visible damages. An area of 10 × 12 m subdivided in quadrats of one square meter was chosen randomly in each plot. In these quadrats, we counted the number of nymphs and galleries, and measured their distances from the axes (X and Y) and their depths (Z). An approach to spatial distribution was performed with indexes of variance-to-mean. We observed that the nymphs of Q. gigas present gregarious habits, not necessarily around the attacked tree; are most commonly found at the fourth and fifth instars; and that gallery depths ranged from eight to 35 cm regardless of the attack intensities.i |
