Asante, S. K. | Kumar, R.
In Ghana, females of Temnoschoita quadrimaculata [T. quadripustulata] were observed to lay eggs singly in wounds cut into the fronds and trunk of oil palms. The feeding activity of larvae sometimes killed young palms. Mated females had a mean preoviposition period of 16 days and a mean lifespan of 106 days in the laboratory (at 21.5-35.6øC). The mean number of eggs per female was 325. The incubation period of eggs was 3-5 days. In the field, the developmental period of the larvae was 25-46 days, and there were 6 overlapping generations of the curculionid. The alternative food-plants were observed to be coconut palms, raffia palms, banana trees and sugarcane. Natural enemies of the curculionid included a species of ant in the genus Paltothyreus, an unidentified tabanid larva, the reduviids Pisilus tipuliformis, Acanthaspis bilineolata, Aulacosphodrus leucocephalus, Rhynocoris sp., R. albopilosus, Santosia maculata, Vestula lineaticeps and Sphedanovarus sp. and an unidentified hymenopterous parasite.
