A -d-glucan exohydrolase was purified from the cell walls of developing maize Zea mays L. shoots. The cell wall enzyme preferentially hydrolyzes the non-reducing terminal glucosyl residue from 13--d-glucans, but also hydrolyzes 12-, 16-, and 14--d-glucosyl units in decreasing order of activity. Polyclonal antisera raised against the purified exo--d-glucanase ...

Vermiculite worked well, but made separating puparia from rearing medium difficult and was expensive 0.60pan. Possibly because of the added rigor of separating puparia from the medium, eclosion was also lower with vermiculite, 57 vs. 75 for wood shavings. Cottonwood shavings were comparable to vermiculite, but at times difficult to procure.
