The second brood of stalk-borers does not exert such a decided influence, because the plant is then strong enough to resist the attack, for the burrows of the insect (Fig. 165, 3) are not sufficiently large to prevent the flow of sap. 405. Life History of the Stalk-borer.--There are two broods of Sesamia fusca and three of the other species of stalkborer, during the season. The last brood passes the winter as larvae within the stalks or in the cob, and in late-harvested ears they are often found wrapped up between the husk and the ear. These larvae pupate and then change into moths, which emerge between October and December. If maize plants are'available, the female moths begin to lay their eggs almost immediately, but always at night, hiding during the day. These eggs are deposited in clusters under the edges of the leafsheaths, and hence are protected from destroying agents; they are faintly visible through the sheaths, and vary in number from 5 or Io to over 100. The eggs hatch in seven to nine days. The young larvae begin feeding on the maize-stalk at once, quickly eating their way towards the centre; "they are very careful to remain under the sheath all the while, and it affords them perfect protection from rain or insecticides." CHAP. When the food supply of one plant is exhausted, the larvae x' leave it and search for fresh plants. On reaching maturity, about the first week in January, the larva clears out a portion of the burrow which it has tunnelled into the stalk, prepares an opening through which the adult can escape (Fig. 165, 3), and then transforms to a dark-brown pupa, as shown in Fig. 165, 7, and 7A. It remains in the pupal stage from ...
