“…B. oleae was previously recovered from overwintered fruit collected in coastal regions (Yokoyama et al 2006, Burrack et al 2011, but not in the interior valleys. Avidov (1954) reported that adult B. oleae are inactive below 16.7ЊC.…”

“…In CaliforniaÕs coastal and interior olive growing regions, adult B. oleae have been caught in baited traps throughout the year, although in relatively low numbers during the winter and spring seasons (Yokoyama et al 2006, Burrack et al 2011). This current study shows that B. oleae can indeed survive and overwinter as an adult in CaliforniaÕs interior valley; female ßies held in Þeld cages beginning in October survived up to 273 d (until June the following year) when supplied with food and water ( Table 1).…”

“…B. oleae larvae have been collected from overwintered fruit in the spring and baited traps caught adult ßies in both winter and early spring periods (Yokoyama et al 2006, Burrack et al 2011. In CaliforniaÕs interior valley, baited traps also caught low numbers of adult B. oleae in winter and early spring (Yokoyama et al 2006), but it is unknown how long the adult survives in the Þeld.…”

Overwintering Survival of Olive Fruit Fly (Diptera: Tephritidae) and Two Introduced Parasitoids in California

The overwintering survival and development of olive fruit fly, Bactrocera oleae (Rossi), and the endoparasitoids, Psyttalia humilis Silvestri and P. lounsburyi (Silvestri), were investigated at sites in California's interior valley and coastal region. In the interior valley, adult flies survived up to 4-6 mo during the winter when food was provided. Adult female flies could oviposit in late fall and early winter on nonharvested fruit and, although egg survival was low (0.23-8.50%), a portion of the overwintered cohort developed into adults the following spring; percentage of survival was negatively correlated to daily minimum temperature. P. humilis and P. lounsburyi successfully oviposited into host larvae in late fall, and their progeny developed into adults the following spring, although with a low percentage (0-11.9%) survivorship. Overwintering survival of puparia of the olive fruit fly and immature larvae of P. humilis and P. lounsburyi (inside host puparia), buried in the soil, were tested at an interior valley and coastal site. Survival of olive fruit fly ranged from 0 to 60% and was affected by the trial date and soil moisture. Overwintering survival of both the fruit fly and tested parasitoids was lower at the colder interior valley than the coastal site; P. humilis immature stages had the highest mortality levels while B. oleae pupae had the lowest mortality levels. The spring emergence pattern of the tested insects was well predicted by a degree-day model. We discuss factors potentially impeding establishment of introduced olive fruit fly parasitoids in California and elsewhere.

“…However, in the S3 station inwards away from the influences of the ocean, the pre-imaginal stages were not observed until early September, and the summer genera-tion is not registered. [14] reported that weather conditions significantly affect the course of the growing season of the olive and consequently the bio-ecology of the pest Bactrocera oleae. Indeed, climate conditions change between the different study sites, especially as it approaches the coast.…”

The Bactrocera oleae Rossi fly is the most important olive pest. It is of major economic importance in the olive production area of Essaouira, where weather conditions are optimal for the conduct of the various stages of its life cycle. The lack of phytosanitary treatments worsens this situation. The development of the larval stages and different generations are related to the phenological stages of the olive and are controlled by changes in habitat conditions. Trapping of adult males by Deltas traps baited with sex pheromone, at the four study sites, has identified some characteristics of the evolution of the adult populations' flight dynamics. Our main results show a decreasing gradient of early emergences of different stages from the coast to the continental areas as well as the absence of the summer generation at the inner station. Soil analysis in the two stations showed that the hypogenous pupae wintering in the soil survive until June. Knowledge of the factors involved in the bio-ecology of the olive fly and the phenology of the host allows the elaboration of monitoring/ warning calendars, and phytosanitary measures in order to establish an IPM program adapted to the requirements of olive orchards in the region.

“…Daane and Johnson (2010) reviewed the olive fruit ßy control literature and included studies of the pest in California. The distribution of olive fruit ßy in different olive production regions of the state has been delineated with trapping programs (Burrack et al 2011) and different trapping techniques . In general, high populations of olive fruit ßy occur in cool, humid coastal areas, and low numbers of the pest are found in the hot, arid areas of California, such as the San Joaquin Valley where olives are grown for canning.…”

The biology of olive fruit fly, Bactrocera oleae (Rossi), was studied in the laboratory, greenhouse, and in canning olives, Olea europaea L., in relation to California regional climates. Adults survived in laboratory tests at constant temperatures and relative humidities of 5 degrees C and 83%; 15 degrees C and 59%; 25 degrees C and 30%; and 35 degrees C and 29% for 15, 6, 3, and 2 d without provisions of food and water and for 37, 63, 25, and 4 d with provisions, respectively. In a divided greenhouse, adults survived for 8-11 d in the warm side (36 degrees C and 31% RH daytime); and in the cool side (26 degrees C and 63% RH daytime) 10 d without provisions and 203 d with provisions. A significantly greater number of adults survived in the cool side than the warm side, and with provisions than without. First and last eggs were oviposited in olive fruit when females were 6 and 90 d old, respectively. The highest number of eggs was 55 per day in 10 olive fruit oviposited by 10 28 d-old females, with maximum egg production by 13-37 d-old females. A significantly greater number of ovipositional sites occurred in all sizes of immature green fruit when exposed to adults in cages for 5 d than 2 d. Adults emerged from fruit with a height of > or = 1.0 cm or a volume of > or = 0.2 cm3. More than seven adults per 15 fruit emerged from field infested fruit with a height of 1.1 cm and volume of 0.1 cm3. Larval length was significantly different among the first, second, and third instars and ranged from 0.7 to 1.6, 2.4-4.3, and 4.8-5.6 mm at 14 degrees C; 0.8-1.1, 1.9-2.9, and 3.9-4.4 mm at 21 degrees C, and 0.7-1.3, 2.4-2.9, and 4.4-4.8 mm at 26 degrees C, respectively. Survival of pupae to the adult stage was significantly lower at 26 degrees C than 14 degrees C or 21 degrees C. The period of adult emergence began at 38, 14, and 11 d over a period of 8, 5, and 1 d at 14, 21, and 26 degrees C, respectively. Findings were related to the occurrence and control of California olive fruit fly infestations.
