ThebraconidparasitoidFopiusarisanus(Sonan)(Hymenoptera:Braconidae)isacandidate for augmentative biological control of tephritid fruit ßies. In the Puna district of Hawaii Island, F. arisanus parasitized 41Ð72% of oriental fruit ßies, Bactrocera dorsalis (Hendel), in wild common guava, Psidium guajava L.; strawberry guava, Psidium cattleianum Sabine; and tropical almond, Terminalia catappa L. In...

This study quantitatively describes the host-searching behavior of Fopius arisanus (Sonan) (Hymenoptera: Braconidae), an important egg-larval parasitoid of tephritid fruit fly pests, on coffee berries infested with host eggs of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). We also investigate the parasitoid’s response to local variation in host patch qualit...

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). Or...

This study investigated the interactions of the pupal fruit ßy parasitoid, Dirhinus giffardii Silvestri, with each of four eggor larval-pupal fruit ßy parasitoids: Fopius arisanus (Sonan), Diachasmimorpha longicaudata (Ashmead), Diachasmimorpha kraussii Fullaway, and Psyttalia concolor (Szépligeti) in Hawaii. F. arisanus attacks host eggs, whereas the other three attack host larvae; all four pa...

Pachycrepoideus vindemmiae Rondani is an ectoparasitic idiobiont parasitoid attacking puparia of many cyclorrhaphous Diptera. This study investigated its potential impact as a facultative hyperparasitoid of four other primary tephritid fruit Xy parasitoids in Hawaii, Fopius arisanus (Sonan), Diachasmimorpha longicaudata (Ashmead), Diachasmimorpha kraussii Fullaway, and Psyttalia concolor (Szépl...

Abstract Fopius arisanus is a parasitoid of Bactrocera fruit flies. In sub‐tropical Australia, it can cause >30% parasitism Queensland fly, tryoni . There has been minimal research effort globally, and none in to determine how the abundance this species be maintained increased through conservation biological control. We carried out three activities aimed at conserving landscape: (i) testing ...

Area-wide control of the Mediterranean fruit fly (=medfly), Ceratitis capitata (Wiedemann), typically involves sterile insect technique (=SIT), and at present the ‘‘Temperature Sensitive Lethal’’ (=TSL) strain is commonly mass-reared for such releases. In theory, and with some experimental support, the augmentative addition of parasitoids to sterile releases can suppress pest populations to a g...

Fopius arisanus and Psyttalia fletcheri are egg and larval parasitoids, respectively, of tephritid fruit flies including the melon fly, Bactrocera cucurbitae. We investigated the consequences of parasitization when eggs or larvae of melon flies were exposed to F. arisanus or P. fletcheri alone, or to both in succession. In addition, we evaluated the effect of fruit substrates on host preference...
