FRONTAL GLAND DEHISCENCE IN THE BRAZILIAN TERMITE SERRITERMES-SERRIFER (ISOPTERA, SERRITERMITIDAE)

The primary function of the soldier caste in the Isoptera is the defense of the termite society. The simplest defense is mechanical with oversized mandibles. Besides the mandibles, some termite soldiers use exocrine glands as a means of chemical defense. These glands produce substances which are toxic and/or repellent to termites enemies. Here we report the only case in the Neotropical fauna of dehiscence of the frontal gland in the soldier caste of the Brazilian termite, Serritermes serrifer (Bates).
