A regional upsurge affected countries along the Red Sea. It developed as a result of a cyclone in June 1996 and heavy rains in November. Infestations were primarily concentrated in Saudi Arabia and to a lesser extent Egypt, Eritrea, Ethiopia, northern Somalia, Sudan, and Yemen. Large-scale control operations in Saudi Arabia brought the upsurge to an end by the summer of 1998.
