Table 4 Results of the multivariate analysis of variance for the walking behavior of the 3rd instar larvae of key lepidopteran pests (i.e., S. frugiperda and A. gemmatalis) in arenas treated with either the LC10 or LC50 of the oil of S. guianensis.

From: Essential oil of Siparuna guianensis as an alternative tool for improved lepidopteran control and resistance management practices
