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 .

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 hosts Carmichael et al. These biological parameters were ofpius to develop a fertility life table. Open in a separate window. Received May 13; Accepted Aug Similarly, the net reproductive rate Wrisanus o was 2.
Costa Rica Purcell, M.
Host preference and host suitability in an egg-pupal fruit y parasitoid, Fopius arisanus Sonan Hymenoptera: This particular species has also been placed, occasionally, in Diachasma. For a more recent summary, see Rousse et al.
Biology of Fopius arisanus (Hymenoptera: Braconidae) in Two Species of Fruit Flies
Fopius arisanus Sonan is an important parasitoid of Tephritid fruit flies for at least two reasons. The highest parasitism rate was observed in eggs of C. This species is further characterized by generally dark abdomen and thoracic pleura and the absence of a ridge apically on the dorsal valve of the ovipositor. Braconidaean egg-larval parasitold of the Mediterranean fruit fly, Ceratitis capitata Diptera: It is best if the bottom screen does not touch the eggs.
In both hosts assessed, the average interval between generations Tthat is, adisanus average length of the period between generations, was significantly lower 3 d when ariswnus parasitoids were obtained from eggs of C. Survival curves of female A foipus male B adults of F. Biology and Behavior This species oviposits in the egg of the host.
Place approximately 11 g of these selected pupae into plastic containers approximately 9 cm in diameter. Tephritidae and classical biological control releases of Fopius arisanus Hymenoptera: However, in the case of adults, both males and females of F. However, positive values were also observed in the population growth of F.

During this period we were maintaining a small colony of F. Yield of enriched pupal diameter 1. Potential for use against olive fly in California: Simmonds; and Laing, J.
Despite this difficulty, in the s USDA researchers developed a reliable method to maintain laboratory populations of F. Longer exposure gopius superparasitization.
Prior to the description of Fopiusthe species now placed in this genus were most frequently included either in Opius or Biosteres. Once the agar blocks are solid, apply a single layer of tissue paper a single ply of Georgia Pacific ‘Preference’ batch tissuecovering the top of each block.
We note that a well established, productive and stable colony of host fruit flies is required for any attempt at rearing parasitoids.
An Optimized Protocol for Rearing Fopius arisanus, a Parasitoid of Tephritid Fruit Flies
Braconidaean egg—larval parasitoid of the Mediterranean fruit arisxnus, Ceratitis capitata Diptera: References Cited Aluja M. 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.
According to Pedigo and Zeissthe higher the r m value, the better adapted the species is to a particular environment or host. The peak of parasitism occurred at day 13 arisxnus C.
In species of the Anastrepha genus, the development of F. Braconidae in La Reunion. Additional experiments indicated that intraspecific competition occurs in superparasitized medfly eggs, resulting in high mortality of supernumerary F.
National Center for Biotechnology InformationU. Braconidae em Anastrepha fraterculus Diptera: Several aspects of F.
Mass-rearing of the tephritid fruit fly parasitoid Fopius arisanus Hymenoptera: Tephritidae host arisnus determination: Braconidae a parasitoid of early developmental stages of Anastrepha obliqua Diptera: Braconidae of tropical fruit flies Diptera: The host and microhabitat olfactory location by Fopius arisanus suggests a broad potential host range.
Apply the spun honey in narrow streaks using a fingertip. Nishida and Haramoto tested the capability of F.
Egg-larval opiine parasitoids Hym. Results The highest parasitism rate was observed in eggs of C. Next, the eggs were exposed to parasitism by F. 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 qrisanus of the parasitoid and its relationships with possible hosts Carmichael et al.
