Aspidiotus destructor Signoret, an armored scale pest new to the Hawaiian Islands.
Aspidiotus destructor Sign. was not known to be established in Hawaii until 1968, when it was discovered infesting coconut palms on Windward Oahu. Since then the species has been found in many places on Oahu, mainly near the coast, and appears to be spreading, though it has not been recorded from any of the other islands of Hawaii. The damage caused by the insect, its life-history and its natural enemies are discussed. In Oahu, the principal predators observed were the introduced Coccinellids Telsimia nitida Chapin and Lindorus lophanthae (Blaisd.), while two species of Aphytis, A. chrysomphali (Merc.) and a species near A. lingnanensis Comp., were reared. A key to the mature females of species of Aspidiotus known to occur in the Hawaiian islands is provided.
