AbstractCompetitive displacement of fruit fly parasitoids has been a serious issue in the history of fruit fly biological control in Hawaii. This concern regarding competitive risk of new parasitoids has led to an overall tightening of regulations against the use of classical biological control to manage fruit flies. Fopius arisanus (Sonan), an egg–larval parasitoid, is the most effective natural enemy of tephritid fruit flies in Hawaii. This study evaluated the competitive risk of two recently introduced larval parasitoids, Diachasmimorpha kraussii Fullaway and Psyttalia concolor (Szépligeti), to F. arisanus attacking the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). Fopius arisanus won almost all intrinsic competitions against both larval parasitoids through physiological suppression of egg development. 83.3% of D. kraussii eggs and 80.2% of P. concolor eggs were killed within three days in the presence of F. arisanus larvae within the bodies of multi-parasitized hosts. The mechanism that F. arisanus employs to eliminate both larval parasitoids is similar to that it uses against three other early established larval fruit fly parasitoids: F. vandenboschi (Fullaway), D. longicaudata (Ashmead) and D. tryoni (Cameron). It suggests that introduction of these larval parasitoids poses minimal competitive risk to F. arisanus in Hawaii.

Abstract Different densities prerelease packing and times of lethargy in the fruit fly parasitoids Diachasmimorpha longicaudata (Ashmead) were evaluated in order to standardize the process of chilled insect technique for this species. Adults were kept at densities of 0.048, 0.072, 0.096, 0.120, and 0.144 parasitoids/cm2 before release in a México tower, where thermal lethargy was induced at a temperature of 2 ± 2°C for 45 min. Samples of parasitoids were collected to evaluate mortality, survival, fecundity, and flight capacity. All densities showed a similar mortality, both for males (ca. >10%) and females (ca. <7). There was no effect of density on survival and flight capacity in both sexes. On the other hand, fecundity increased with density, 1.66 sons/♀/day, similar to the control. We conclude that a density of 30,000 pupae per cage (0.144 parasitoids/cm2) is adequate for the massive prerelease packaging of the parasitoid D. longicaudata. Regarding the thermal lethargy period, 180 min under 2 ± 2°C conditions, considered as time for management, does not affect the survival, fecundity, and flight capacity of adults. The results obtained are of great utility to establish prerelease packaging parameters for D. longicaudata used in the biological control of Tephritidae fruit fly populations.

Fruit Fly Parasitoids

Fruit flies are economically important pests that infest a wide variety of host trees. The environmental damage caused by traditional pesticide-based control methods has prompted scientists to seek less damaging alternatives such as biological control by native species. Parasitoids, especially Braconidae species, have excellent potential as biological control agents for fruit flies, being both generalists and well distributed geographically. Native fruit trees that support medium or high levels of these parasitoids could therefore play an important role in biological control strategies. A good potential example is Spondias mombin L. in the Brazilian Amazon, which hosts several species of fruit flies and associated parasitoids. Here, we provide a unique synthesis of over nearly two decades of data from the east Amazon, clearly demonstrating the potential of S. mombin to act as a source and reservoir of fruit fly parasitoids. This important ecosystem service (biological control) provided by the parasitoids and supported by S. mombin could be further enhanced through conservation of this plant species in its natural environment.

Fruit Fly Parasitoids

 Fruit-bearing plants in the Brazilian Amazon are mainly attacked by species of Anastrepha, of which about half are endemic to the region. However, tritrophic relations (fly/plant/parasitoid) have only been established for some 25% of the species of Anastrepha in the region. At present, 11 species of hymenopterous parasitoids (Braconidae and Figitidae) have been recorded in the Brazilian Amazon. Parasitoids in general, especially those of the family Braconidae, stand out as the most effective natural enemies of fruit flies of the genus Anastrepha. Doryctobracon areolatus is the most abundant parasitoid and it is associated with the largest number of Anastrepha species in the region. Some fruiting species, for example Bellucia grossularioides (L.) Triana and Geissospermum argenteum Woodson, have been studied aiming at biological control of fruit flies, because they act as reservoirs or multipliers of fruit fly parasitoids. Although research has advanced significantly in the past 20 years, there is a shortage of studies in nearly all states in the region, due to the huge area of the Brazilian Amazon.

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]
