AbstractFemale diphagous parasitoids are endoparasitic as larvae, whereas their males are ectoparasitic. It is possible that males, during their development, eliminate competitors, and this has been proposed as the selective advantage to male ectoparasitism. In this way resources would be partitioned between the sexes. The hypothesis was tested experimentally by observation of whether mated females were capable of recognizing parasitized hosts, and whether they then deposited male eggs on them (because ectoparasitic larvae are supposed to be good competitors). The behaviour of individual Coccophagus bartletti ANNECKE & INSLEY (Aphelinidae) wasps did not follow prediction, and an alternative hypothesis is proposed. Selection pressures from the environment (e.g. host) need not be the same for both sexes, and if male eggs of the pre-diphagous aphelinid were treated differently at oviposition from female eggs (as is found in at least one extant species of aphelinid with otherwise conventional host relationships), a host shift at speciation could account for the divergence in host relationships of the sexes.

Many insects harbour facultative symbiotic bacteria, some of which have been shown to provide resistance against natural enemies. One of the best-known protective symbionts is Hamiltonella defensa , which in pea aphid ( Acyrthosiphon pisum ) confers resistance against attack by parasitoid wasps in the genus Aphidius (Braconidae). We asked (i) whether this symbiont also confers protection against a phylogenetically distant group of parasitoids (Aphelinidae) and (ii) whether there are consistent differences in the effects of bacteria found in pea aphid biotypes adapted to different host plants. We found that some H. defensa strains do provide protection against an aphelinid parasitoid Aphelinus abdominalis. Hamiltonella defensa from the Lotus biotype provided high resistance to A. abdominalis and moderate to low resistance to Aphidius ervi , while the reverse was seen from Medicago biotype isolates. Aphids from Ononis showed no evidence of symbiont-mediated protection against either wasp species and were relatively vulnerable to both. Our results may reflect the different selection pressures exerted by the parasitoid community on aphids feeding on different host plants, and could help explain the maintenance of genetic diversity in bacterial symbionts.

AbstractAphelinidae are all insect parasitoids, and most species are associated with nymphal stages of Homoptera: Sternorrhyncha, either as primary parasitoids or hyperparasitoids. The occurrence of egg parasitism in aphelinids has been recorded in eight of the 38 valid genera and these records are reviewed; it is particularly common in the genus Centrodora, which is shown to be the most polyphagous in the family. One species, C. darwini (Girault), is given special attention because of its occurrence in three recent surveys for biological control agents of crop pests. It is briefly redescribed, diagnosed, and shown to be the most polyphagous aphelinid known. A checklist of Australian Centrodora spp. is given, including the new combination Centrodora grotiusi (Girault) comb. n. The purported evidence for the classification of certain Encarsia spp. associated with eggs of Lepidoptera as ‘heterotrophic parasitoids’ is re-examined and dismissed.

AbstractPrimers for DNA amplification using the polymerase chain reaction (PCR) were synthesized for a microsatellite locus isolated from a partial genomic library of the aphid parasitoid Aphelinus abdominalis (Dalman). Screening for genetic polymorphism at this locus in two laboratory strains of this wasp revealed the presence of two alleles different in the number of (GT) and (GGC) repeats. The relative frequencies of the two alleles were not significantly different between the two strains or between diploid females and haploid males. Heterozygosity at this microsatellite locus was estimated to be 0.40 which is within the range in other hymenopterous species. Given that A. abdominalis is a good candidate for augmentative release programmes in greenhouses against aphids, we suggest that microsatellite markers may have application in discriminating among aphelinid sibling species and strains. The markers provide a means for studying the performance and impact of selected parasitoid lines on pest dynamics in field release experiments.

A la suite de l'introduction accidentelle du puceron russe du ble diuraphis noxia (mordvilko, 1913) aux etats-unis en 1986, un programme de lutte biologique contre ce ravageur a ete mis en place. Les recherches ont ete realisees dans divers domaines pour mettre au point des strategies de lutte, telles que la selection et l'introduction de parasitoides, de predateurs et d'organismes pathogenes. L'etude presentee ici a ete realisee dans le but d'evaluer la pathogenicite de l'hyphomycete paecilomyces fumosoroseus (wise) brown & smith sur le puceron russe du ble, ainsi que les effets directs et indirects du champignon sur aphelinus asychis (walker), un endoparasitoide primaire du ravageur. Cette etude a ete conduite dans diverses conditions environnementales, en laboratoire et au champ. L'activite pathogene, basee sur une forte mortalite pendant les trois premiers jours apres l'application du champignon ainsi que sur le pourcentage eleve d'insectes mycoses, montre pour la premiere fois le potentiel represseur de p. Fumosoroseus contre d. Noxia. Les resultats de l'interaction hote-pathogene-parasitoide montrent que le comportement discriminatoire d'a. Asychis vis-a-vis de d. Noxia infecte par p. Fumosoroseus apres le sondage de l'hote reduit la possibilite de ponte dans les pucerons malades et augmente les chances de transmission du champignon. Par ailleurs, aucun effet negatif n'a ete observe, sur la longevite, la fecondite et la taille des femelles de la generation f1 emergees de d. Noxia, quel que soit l'intervalle de temps note entre l'application fongique et le parasitisme par a. Asychis. Ces constatations montrent bien l'effet combine entre p. Fumosoroseus et a. Asychis. Cependant, dans les conditions les plus favorables au champignon, p. Fumosoroseus provoque une forte mortalite des adultes d'a. Asychis et reduit la vitesse de marche et la distance parcourue des femelles survivantes traitees, ce qui pourraient entrainer dans les conditions naturelles une reduction du taux de parasitisme et/ou de predation du parasitoide. Contrairement a ce que l'on observe au laboratoire, le champignon n'a eu aucun effet defavorable sur le parasitoide quand les deux agents ont ete associes au champ. Ces nouvelles connaissances sur les interactions entre a. Asychis et les champignons entomopathogenes de d. Noxia pourront permettre de definir une meilleure strategie pour les programmes de lutte integree

The congeneric wasps, Encarsia formosa and E. pergandiella (Hymenoptera: Aphelinidae) are solitary endoparasitoids with an overlapping host range. Despite their similarities these wasps produce eggs that differ markedly in size. This dissertation details research conducted to determine differences in the egg provisioning strategies of these two wasp species and to understand how these differences correlate with differences in their early development. The use of the yolk protein, vitellogenin, was examined in the two wasps. A vitellogenin gene was isolated from E. formosa and the mature gene product observed in ovary extracts. Evidence for the use of vitellogenin was not found in an analysis of ovary extracts from E. pergandiella and a gene for vitellogenin was not detected in the genome of this wasp. Embryonic development times for the two parasitoids were studied in hosts of different ages. The embryonic development time of E. formosa is significantly shorter than that of E. pergandiella regardless of the host stage parasitized. This suggests that the rate of embryonic development of E. pergandiella is much more closely linked to that of the host than the development rate of E. formosa. The quantity and composition of amino acids in the eggs of the two wasps was followed over the course of embryonic development. The quantity of amino acid in the eggs of E. formosa does not increase during embryonic development while the eggs of E. pergandiella absorb more than 30 times the quantity of amino acids from the host hemolymph during embryonic development than is present in the eggs at the time oviposition. Only E. pergandiella appeared capable of absorbing and utilizing [¹⁴C]-labeled lysine in an in vitro system. The capacity of E. pergandiella eggs to absorb host nutrients is correlated with the development of a multinucleate extraembryonic membrane that grows to completely encompass the embryo at a very early stage of development. Evidence was found for pinocytosis of material by the embryo from the space bounded by the extraembryonic membrane. A similarly developed extraembryonic membrane was not observed in the eggs of E. formosa .

Avec l'arrivee recente en europe d'un nouveau ravageur, bemisia tabaci (gennadius) (homoptera, aleyrodidae), des etudes ont ete entreprises afin de controler ses populations en melange ou non avec trialeurodes vaporariorum (westwood) (homoptera, aleyrodidae) a l'aide de parasitoides (hymenoptera, aphelinidae). Des travaux ont ete realises sur les caracteristiques biologiques de b. Tabaci sur ageratum conyzoides, issu de populations du sud-est de la france. Cette espece s'est averee mieux adaptee a des temperatures plus hautes que t. Vaporariorum. A 22c, la duree de developpement de b. Tabaci est de 25 jours, la longevite de 33 jours avec une fecondite de 164 ufs. Sa strategie de colonisation verticale des plants de tomate en serre est egalement originale par l'emplacement de ses populations dans les parties basse et mediane. Les modalites d'elevage des aleurodes et des parasitoides ont ete definies pour standardiser les conditions experimentales. Afin d'etudier les caracteristiques biologiques des adultes de parasitoides, des experimentations ont ete menees sur encarsia formosa gahan, pour determiner un modele de pondoir et les facteurs influant sur la biologie. Dans les conditions les plus favorables, la longevite des femelles est de 39 jours, la fecondite de 264 ufs et la predation de 67 larves. Des resultats interessants ont ete obtenus en serre sur les populations de b. Tabaci en melange avec t. Vaporariorum avec des lachers d'e. Formosa eleves pendant plusieurs generations sur b. Tabaci. Des resultats encourageants ont egalement ete obtenus avec eretmocerus mundus haldeman, espece qui ne parasite que b. Tabaci. Enfin, e. Pergandiella howard montre sa capacite de controler des la premiere generation de l'hote les populations d'aleurodes ; cependant, son comportement d'hyperparasitoide tend a diminuer son efficacite dans le temps. L'ensemble de ces resultats laisse entrevoir la possibilite de controler les populations de b. Tabaci en serre sous forme de traitements inondatifs de parasitoides

Publicación a texto completo no autorizada por el autor
Coccophagus rusti Compere, 1928 es un hymenóptero perteneciente a la familia Aphelinidae, que actúa como parasitoide de queresas. Esta especie fue introducida al Perú por Flanders en 1968 para el control biológico de Saissetia spp. (Hemiptera: Coccidae) en plantaciones de olivo. A pesar de su efectividad como parte del conjunto de controladores introducidos para el control de dicha plaga durante la década de 1970, en el Perú no se han realizado estudios sobre el ciclo biológico o la crianza de este parasitoide, bajo condiciones de laboratorio ni de campo, lo cual limita su empleo en el control biológico de plagas de cóccidos en nuestro país. Por tal razón el presente trabajo de investigación realizado durante las estaciones de primavera y verano de los años 2007 y 2008 en las instalaciones del Laboratorio del área de la Unidad de Producción de Insectos Benéficos de la Subdirección de Control Biológico (SCB) – Servicio Nacional de Sanidad Agraria en Vitarte, tuvo como objetivo determinar el ciclo biológico y la capacidad de parasitación de C. rusti bajo condiciones de laboratorio, como punto de partida para subsecuentes estudios e investigaciones. Los resultados sugieren que bajo condiciones controladas, el parasitoide es un eficiente controlador de la queresa S. coffeae.

Helytoky is a type of parthenogenesis whereby females produce only female offspring without the involvement of males, even where males are occasionally produced. In the last few years, strong circumstantial evidence has implied that thelytoky can be caused by micro-organisms called Wolbachia in at least some species of wasps. The thelytoky can be "cured" by treatment with antibiotics. Further Wolbachia-like organisms can be found in microscopic examinations and genetically identified through their DNA. The aphelinid wasps, and especially species in the genus Aphytis, are among the most important of all classical biological control agents. Aphytis species are critical in the biological control of scale insect pests in commercial orchards and ornamental plantings. About 30% of Aphytis species are thelytikous, of which we were able to study three in detail. In all three, thelytoky was curable by treatment with antibiotics and Wolbachia were identified morphologically and through their DNA. In contrast, Wolbachia were not detectable in biparental species of Aphytis. Studies of Wolbachia gene sequences obtained from Aphytis showed that they were most closely related to those from a very distantly related wasp, Muscidifurax uniraptor, strongly implying that the Wolbachia can be horizontally transferred. As revealed by electron microscopy, the Wolbachia show a strong association with the nurse and follicle cells of the female wasps.
