Figure 2 in Trophic relationship between Chrysoperla externa (Neuroptera: Chrysopidae) and Planococcus citri (Hemiptera: Pseudococcidae) associated with rose bushes

Figure 2 Proportion of second-instar nymphs of Planococcus citri consumed by second-instar larvae of Chrysoperla externa as a function of the nymph density of the mealybug and predator:prey ratio. Different letters at the end of the curves indicate significant differences by Tukey's multicomparison test (p <0.05).
