Abstract:The pecan nut case-bearer is the most important insect that attacks the pecan in Texas. A study of the life history is essential to an approach at control methods. The following article summarizes the main points in the life history which has been studied for six years at several points in the state of Texas. There are either two or four generations of this insect a year which fact probably depends 011 the food supply. The larva spends the winter in a hibernaculum which it spins on the side of a bud. The first larva emerges from its hibernaculum in March or April and bores into the new growth. The larval and pupal period of the spring brood is passed within this growth, The adult deposits the eggs on tip of the nut or in grooves on the sides. The young larva hollows out the interior of the nuts and pupates within one. The larvae o(the second generation also hollows out the nut but the larval stage of the third generation is usually passed within the shuck.
