Fruit flies

Eurytoma tephritidis Fullaway (Hymenoptera: Eurytomidae) is an exotic solitary larval endoparasitoid that has been recorded to parasitize gall-forming tephritids in Hawaii. We surveyed E. tephritidis parasitism of Tetreuaresta obscuriventris (Loew.), Ensina sonchi (L.), Acinia picturata (Snow), Procecidochares utilis Stone, P. alani Steyskal, Trupanea sp. nr. cratericola, and T. dubautiae (Bryan) (Diptera: Tephritidae) on four major Hawaiian islands. No wasps emerged from T. obscuriventris and E. sonchi. Among other species, percent parasitism ranged from less than 1% […]

Populations of successfully established exotic organisms rarely reach noticeable densities in their new environment, and little information is currently available on the population dynamics of the exotic insects released on the Hawaiian islands. In the present study, we surveyed present incidence of a tephritid fly of New World origin, Tetreuaresta obscuriventris (Loew.), on the island of Kauai.

The flower-head feeding fly Acinia picturata (Diptera: Tephritidae) was deliberately introduced from Mexico into Hawaii in 1959 for biological control of the exotic weed Pluchea odorata (Snow) (Asteraceae). Neither field efficacy nor possible non-target effects of the fly have been evaluated in the 40 years since the introduction. We assessed the impact of the fly on both its target

We performed a series of laboratory experiments to determine the effects of shade, soil moisture, and soil compaction on the selection of pupation habitats by wandering late instar Oriental fruit flies, Bactrocera dorsalis (Hendel). Larvae showed a strong preference towards pupating in shaded rather than brightly lit areas, in moist rather than dry soil, and in soil

An effective lure-and-kill trap is a potentially important instrument in monitoring and controlling Oriental fruit flies, Bactrocera dorsalis(Hendel). A number of experiments were performed in a commercial guava (Psydium guajava L.) orchard to determine how fly captures are affected by combining visual and olfactory stimuli, and by the timing of trap deployment relatively to host phenology.
