Distribution and abundance of Dacus dorsalis (Diptera: Tephritidae) in native and exotic forest areas on Kauai
Environmental Entomology 12 (4), 1185-1189
Abstract: The distribution and relative abundance of the oriental fruit fly, Dacus dorsalis Hendel, were determined in native forests and surrounding areas on Kauai. Generally, relatively low numbers were captured in native forests. Low numbers were trapped at high elevations (>800 m), intermediate numbers at middle elevations (400 to 800 m), and high numbers at low elevations (<400 m). Low populations in areas of native forest appeared to be associated primarily with infestation of (1) strawberry guava, Psidium cattleianum Sabine, in nearby middle and upper elevation localities, and (2) common guava, P. guajava L., in upland and lowland exotic forest areas.
