Injury to petioles.—Melon fly larvas, which had recently hatched, were found within the petioles of leaves, but nearly, full-grown maggots were never observed within this part of the plant. In order to ascertain whether the pest could complete its larval period within a petiole, ten maggots of different sizes were placed within a half dozen leaf-stalks. All of the larvae obtained sufficient nourishment from the wall of the petioles to complete their development. While most of the maggots bored out of the petioles to pupate, others pupated within the leaf-stalks close to the node of the stem. 7. Injury to flowers.—The larvae that hatch from the eggs deposited in the anthers, first feed upon and destroy these structures (plate XXIX, fig. 28); then they may eat out the.
