Bactrocera dorsalis (Hendel), Bactrocera papayae Drew & Hancock, Bactrocera philippinensis Drew & Hancock, and Bactrocera carambolae Drew & Hancock are pest members within the B. dorsalis species complex of tropical fruit flies. The species status of these taxa is unclear and this confounds quarantine, pest management, and general research. Mating studies carried out under uniform experimental ...

Males of some species included in the Bactrocera dorsalis complex are strongly attracted to methyl eugenol (ME) (1,2-dimethoxy-4-(2-propenyl) benzene), a natural compound occurring in a variety of plant species. ME feeding of males of the B. dorsalis complex is known to enhance their mating competitiveness. Within B. dorsalis, recent studies show that Asian and African populations of B. dorsali...

Forced infestation studies were conducted to determine whether northern or southern highbush blueberries, Vaccinium corymbosum L., are hosts for the invasive tephritid fruit flies in Hawaii. Fruit were exposed to gravid female flies of Bactrocera dorsalis Hendel (oriental fruit fly), Ceratitis capitata (Wiedemann) (Mediterranean fruit fly), or Bactrocera cucurbitae Coquillet (melon fly) in scre...

The current study describes seven species that are new to the lichen mycota of South Korea. A taxonomic description of Arthonia excipienda, A. radiata, Arthothelium ruanum, Enterographa leucolyta, Fissurina elaiocarpa, Rinodina oleae, and Thelotrema porinaceum was given and supported by distribution, ecology, and illustrations. Each species was compared with a species showing close resemblance.

A survey in olive orchards Istria (Croatia) was carried out from 2016 to 2018 investigate pathogens potentially associated with decline and dieback. In nine orchards, canker-like symptoms were recorded on trunks branches. Six fungal species isolated cankers: Geosmithia sp., Diaporthe Diatrype stigma, Diplodia seriata, Neofusicoccum parvum, Pseudophaeomoniella oleae. Pathogenicity tests conducte...
