To accomplish this, evaluation was carried out using a
DNSA assay to screen gut and head fluids from the different life stages
of D. carolina, using CMC or MCC as cellulase substrates. Activities
against CMC were about 10-fold higher and significantly different
(Kruskal–Wallis ANOVA on ranks, Pb0.001) than against MCC for
both gut and head-derived samples from all stadia (Fig. 1). No
significant differences (Kruskal–Wallis ANOVA on ranks) were
detected when comparing activity against CMC or MCC in gut and
head-derived fluids within a specific life stage
