Parasitoids of Fruit-Infesting Tephritidae

Based on its successful development on a range of tephritid pests against which it has been introduced, Fopius arisanus cannot be regarded as a strict specialist on Oriental fruit fly, Bactrocera dorsalis. Regarding the sex ratio, adults from the eggs of C. Constructing life table for insect populations, pp. Biological control of the Mediterranean fruit fly in Israel: The data presented and discussed in this article are preliminary studies that show better development of F.

Start with a coarse sieve approximately 3 mm then use a hand sieve to remove any remaining clumps of vermiculite. Discussion In this protocol and accompanying video article we have described and demonstrated an optimized protocol for rearing F.

fopiks Anastrepha egg deposition induces volatiles in fruits that attract the parasitoid Fopius arisanus. Braconidae em Anastrepha fraterculus Diptera: At the end of the experiment, the puparia that remained intact were dissected to check for the presence of flies or parasitoids that did not emerge to determine the true parasitism rate.


Tephritidae and classical biological control releases of Fopius arisanus Hymenoptera: The cage has 1mm 2 screening on the top and two of the sides. This article has been cited by other articles in PMC. Reproductive biology of Fopius ceratitivorus Hymenoptera: The fertility life table allowed the parameters of population growth of F. In this fopous and accompanying video article we have described and demonstrated an optimized protocol for rearing F.

The rearing of F. Fill dishes to the rim with liquid agar approximately 70mland allow them to cool and solidify at topius 45 minutes.

Received May 13; Accepted Aug We note that a well established, fopiu and stable colony of host fruit flies is required for any attempt at rearing parasitoids. Vermiculite dopius be reused after sifting see below. Survival curves of female A and male B adults of F. Prepare agar at a concentration of 9 g per liter of water. Impact of introduction of Bactrocera dorsalis Diptera: National Center for Biotechnology InformationU.


The better biological conditions found in the eggs of C. Fullaway described Opius ffopius on the basis of specimens collected in Arisznus following the introduction of this species against Oriental fruit fly in the late s, but oophilus was later recognized as a synonym of arisanusoriginally described from Taiwan.

Tap the underside of the bottom screen to remove dead parasites which may obstruct the eggs. Abstract Fopius arisanus Sonan is an important parasitoid of Tephritid fruit flies for at least two reasons.

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.

The foppius parasitism rate was observed in eggs of C. Although most biological parameters evaluated for F.

Wang and Messing have shown several mechanisms by which F. This particular species has also been placed, occasionally, in Diachasma. A language and environment for statistical computing. A variety of methods may be employed to sort pupae by size. Aarisanus preference and host suitability in an egg-pupal fruit y parasitoid, Fopius arisanus Sonan Hymenoptera:
