“…In the warmer interior valleys, fly population growth may be limited during periods of high summer temperature , which increases adult fly mortality and reduces their movement and oviposition success (Wang et al 2009a). This might also impact parasitoid establishment and effectiveness in California via direct mortality of Psyttalia as developing larvae or as foraging adults Sime et al 2006a;Yokoyama et al 2010). Similarly, the failure of P. concolor to establish in southern Europe was partly contributed to unsuitable climatic conditions (Raspi and Loni 1994).…”

Psyttalia lounsburyi (Silvestri) and P. humilis (Silvestri) (Hymenoptera: Braconidae) were evaluated in California for their potential to control the invasive olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae). Psyttalia lounsburyi is a specialist on B. oleae while P. humilis also attacks other tephritid species. Field cage trials, conducted from 2006 to 2009, were used to compare P. lounsburyi and two populations of P. humilis (Kenya and Namibia) in California's interior valley and coastal regions. Both parasitoid species reproduced on B. oleae in all trials. Under similar abiotic conditions, offspring production per female was higher in P. humilis than in P. lounsburyi, suggesting that host specificity by P. lounsburyi does not confer a higher efficiency on B. oleae in cultivated olives. Two abiotic factors were shown to impact parasitoid efficiency. First, adult parasitoid survival was poor during periods of high summer temperatures, common to the olive production areas in California's interior valleys. Second, parasitism levels were lower on B. oleae larvae feeding in larger Ascolano cv. fruit than in smaller Manzanillo cv. fruit. Results are discussed relative to biological control of B. oleae in commercial olives and the usefulness of natural enemies specialized to attack fruit flies in wild olives compared with the larger cultivated olive fruit.

“…All were supplied by Russell Messing at University of Hawaii, where they had been reared on Medfl y. Similarly, colonies of P. humilis maintained on Medfl y in Guatemala were sent to California, supplied by Pedro Rendon of the USDA APHIS Plant Protection and Quarantine program (Yokoyama et al 2008(Yokoyama et al , 2010.…”

“…Nonetheless, we consider P. concolor and P. humilis to be important to screen for use in California biological control. Their native range spans much of northern and eastern Africa (Wharton and Gilstrap 1983) and, given the diversity of habitats and climates encompassed, they likely comprise several biotypes, or even new species or genetically differentiated populations (Rugman-Jones et al 2009), some of which may be better suited to control olive fruit fly in California (Yokoyama et al 2010).…”

“…To date, P. lounsburyi has been released and recovered in fi eld-cage studies, but has not yet been shown to overwinter. More work has been done with P. humilis, which is easier to rear, and levels of up to 60% parasitism have been reported from cage studies (Wang, Johnson, Daane, Yokoyama 2009;Yokoyama et al 2008Yokoyama et al , 2010 Offspring per female establish and thrive without repeated augmentation.…”

“…In the same context, P. lounsburyi and P. humilis were evaluated in California for their potential to control the invasive olive fruit fly, B. oleae and it was demonstrated that adult parasitoid survival was low during summer because of the high prevailing temperatures (Wang et al 2011) causing high mortality of Psyttalia sp. as in different developmental stages (Daane et al 2008;Sime et al 2006a;Yokoyama et al 2010). As a matter of fact, temperature can lead BC programs to failure like the case of P. concolor which failed to establish in southern Europe Loni 1994 in Wang et al 2011).…”
