generic phytosanitary radiation treatment for tephritid fruit flies provides quarantine security for bactrocera latifrons (diptera: tephritidae).bactrocera latifrons (hendel) (diptera: tephritidae) is a quarantine pest of several solanaceous crops and tropical fruits that are treated using irradiation before export from hawaii to the u.s. mainland. a dose of 150 gy is approved as a generic irradiation treatment for tephritid fruit flies, but no confirmation of efficacy has been reported for b. latifrons. dose response of b. latifrons was used to determine the most tolerant life stage and identify a dose that prevents adult emergence. dat ...201122066179
managing oriental fruit fly (diptera: tephritidae), with spinosad-based protein bait sprays and sanitation in papaya orchards in hawaii.the efficacy of gf-120 nf naturalyte fruit fly bait in combination with field sanitation was assessed as a control for female oriental fruit fly, bactrocera dorsalis (hendel) (diptera: tephritidae), in papaya (carica papaya l.) orchards in hawaii. three different bait spray regimes were evaluated: every row (high use of the bait), every fifth row (moderate use), and every 10th row (low use). orchard plots in which no bait was applied served as controls. for five of the seven biweekly periods tha ...200919610428
evaluation of splat with spinosad and methyl eugenol or cue-lure for "attract-and-kill" of oriental and melon fruit flies (diptera: tephritidae) in hawaii.specialized pheromone and lure application technology (splat) methyl eugenol (me) and cue-lure (c-l) "attract-and-kill" sprayable formulations containing spinosad were compared with other formulations under hawaiian weather conditions against oriental fruit fly, bactrocera dorsalis (hendel), and melon fly, bactrocera cucurbitae (coquillett) (diptera: tephritidae), respectively. field tests were conducted with three different dispensers (min-u-gel, acti-gel, and splat) and two different insectici ...200818613576
weathering and chemical degradation of methyl eugenol and raspberry ketone solid dispensers for detection, monitoring, and male annihilation of bactrocera dorsalis and bactrocera cucurbitae (diptera: tephritidae) in hawaii.solid male lure dispensers containing methyl eugenol (me) and raspberry ketone (rk), or mixtures of the lures (me + rk), and dimethyl dichloro-vinyl phosphate (ddvp) were evaluated in area-wide pest management bucket or jackson traps in commercial papaya (carica papaya l.) orchards where both oriental fruit fly, bactrocera dorsalis (hendel), and melon fly, bactrocera cucurbitae (coquillett), are pests. captures of b. dorsalis with fresh wafers in jackson and bucket traps were significantly highe ...201526470301
vision-mediated exploitation of a novel host plant by a tephritid fruit fly.shortly after its introduction into the hawaiian islands around 1895, the polyphagous, invasive fruit fly bactrocera (zeugodacus) cucurbitae (coquillett) (diptera: tephritidae) was provided the opportunity to expand its host range to include a novel host, papaya (carica papaya). it has been documented that female b. cucurbitae rely strongly on vision to locate host fruit. given that the papaya fruit is visually conspicuous in the papaya agro-ecosystem, we hypothesized that female b. cucurbitae u ...201728380069
irradiation as a phytosanitary treatment for white peach scale (homoptera: diaspididae).irradiation was examined as a potential phytosanitary treatment to control white peach scale, pseudaulacaspis pentagona (targioni-tozzetti) (homoptera: diaspididae), a serious quarantine pest of papaya, carica papaya l., in hawaii. dose-response tests were conducted with second-stage nymphs, adult females without eggs, and adult females with eggs at a series of irradiation doses between 60 and 150 gy to determine the most tolerant stage. the adult female with eggs was the most tolerant stage. in ...200617195662
