Status of Zapriotheca nr. nudiseta as a biocontrol agent for Passiflora tarminiana in Hawaii

Zapriotheca nr. nudiseta (Diptera: Drosophilidae) larvae feed on flower buds of Passiflora tripartita var. mollissima (banana poka) and appear to have potential to disrupt the reproductive cycle of this plant. The fly passed host specificity testing, but was not proposed for release. The colony in quarantine was highly inbred. Further importation of the insect was needed to overcome genetic problems and complete host screening. It will be extremely difficult to assess the impact of this insect because large plants are needed, and the logistics of handling such plants in quarantine are unrealistic. Field studies in South America are not currently feasible (2000). (info from http://www.hear.org/bibliography/references/9451_smith_2002/)
