Fig. 2From: Girdling behavior of the longhorn beetle modulates the host plant to enhance larval performanceObservations on girdling behavior of Phytoecia rufiventris. (a) Behavioral sequence of girdling and oviposition of P. rufiventris. (b) Girdle angles of lower and upper girdling (N = 100). Box indicates 1st and 3rd quantiles. (c) Morphology of naturally girdled E. annuus. Two girdles are indicated with white triangles. (d) Trypan-blue staining of the experimentally girdled and non-girdled stem of E. annuus at 1 and 3 wpg. Blue staining indicates cell deathBack to article page
