The peach twig borer is the major pest of peaches in Central Texas. Although it is present in the eastern portions of the State, it is usually of minor significance. The name of this insect should not be confused with that of the peach tree borer which attacks the trunks of peach and plum trees in East Texas. Early generations of the peach twig borer larvae feed in the twigs of peach and plum trees.
Damage is similar to that caused by the oriental fruit moth.
Varieties which mature fruit late in the season are damaged most severely. Early maturing plums are rarely attacked. The adults are dark gray moths with lighter gray markings. The young larvae are light brown with black heads. As an immature larvae, the peach twig borer passes the winter beneath the bark in a hollowed- out cell called a hibernaculum.
