Abstract. Fopius arisanus (Hym., Braconidae) is an egg–pupal parasitoid of tephritid fruit flies. Since its introduction to Hawaii in the late s, it has caused . Abstract. We describe all immature stages, particularly the previously undescribed instars, of Fopius arisanus (Sonan) (Hymenoptera. Fopius arisanus (Sonan, ) is an egg-pupal parasitoid of Tephritid fruit flies. This Braconid wasp has been utilized for biological control of the Mediterranean .

This indicates that the host provides the biological and physiological conditions necessary to provide all the nutritional requirements for the insects to develop offspring and, thus, generate a greater number of females Quimio and Walter ; Ramadan et al.

Comparative arosanus of Diachasmimorpha longicaudata Hymenoptera: For the rearing of F. In Brazil, the parasitoid used so far in biological control programs for fruit flies of the genera Anastrepha and Ceratitis is the exotic Diachasmimorpha longicaudata Ashmead, Hymenoptera: Tephritidae populations in relation to region, trap type, season, and availability of fruit. National Center for Biotechnology InformationU. Cover the pupation container with a lid and tape the edges of the with masking tape.


We thank Keith Shigeteni for assistance in the insectary and Natasha Sostrom vopius help with computer graphics. In this study, F.

For commercial re-use, please contact journals. Use a clean 2. Collect pupa between 1. Discussion In this protocol and accompanying video article we have described and demonstrated an optimized protocol for rearing F. More recent studies include those of Snowball et al. We refer to these as ‘early pupae’. Acknowledgments We thank Keith Shigeteni for assistance in the insectary and Natasha Sostrom for help with fopiks graphics.

Fopius arisanus fore wing An optimized protocol for rearing Fopius arisanusa parasitoid of tephritid fruit flies.

The authors also report that in experiments with the 4 larval parasitoids none were able to directly destroy F. Although this possibility can occur, it is minimized by the fact that A. The cage has 1mm 2 screening on the top and two of the sides. Discussion The success of biological control programs involving the use of parasitoids to suppress fruit fly populations depends, among other things, on the knowledge of the biology of the parasitoid and its relationships with possible arosanus Carmichael et al.

The experiment was conducted using a completely randomized design with two treatments hosts C. New South Wales Snowball, G. Argentina—introduced in against C. Reproductive Behavior of Biosteres arisanus Sonan Hymenoptera: The arisanis life table showed better biological and reproductive performance for F. Initial work on the biology of this species was published by van den Bosch et al.


This indicates that in eggs of C.

In species of the Anastrepha genus, the development of F. For a more recent summary, see Rousse et al. The holding cages should also have ariswnus tinted portion along the bottom quarter of the glass front to minimize light which can create parasitoid crowding along the front of the cage, resulting in elevated mortality.

Members of the persulcatus species group to which Fopius arisanus belongs are characterized by the presence of striate sculpture on the second metasomal tergum as in Fig. However, further studies parasitism preferences of F. Fopius arisanus oviposition in four Anastrepha fruit fly species of economic importance in Mexico.

Parasitoids of Fruit-Infesting Tephritidae

Potential for use against arisanuus fly in California: Bernardi2 and D. As the first adults emerged, the jar lids were replaced by a screen with 0. Anastrepha egg deposition induces volatiles in fruits that attract the parasitoid Fopius arisanus.

At pupation, the vermiculite was sifted through a galvanized sieve 0.
