Resumen en español

Los parasitoides africanos Cephalonomia stephanoderis Waterston (Bethylidae: Hymenoptera), Prorops nasuta Betrem (Bethylidae: Hymenoptera), y Phymastichus coffea LaSalle (Eulophidae: Hymenoptera) son agentes de control biológico de la broca del café (Coleoptera: Curculionidae). En este estudio, nosotros investigamos en laboratorio la respuesta comportamental de las hembras de esos parasitoides a 14 diferentes longitudes de onda (340–670 nm) contra un control (570 nm, amarillo). Cuando las hembras que no eligieron fueron incluidas en el análisis, ninguna de las especies de parasitoides mostró una preferencia entre 340, 350, 370, 460, 490, 520, 540, 590, 640, and 650 nm con respecto a la longitud de onda control. En contraste, las tres especies de parasitoides fueron más atraídos a longitudes de onda de 380, 400 y 420 nm que a la longitud de onda control. Phymastichus coffea y P. nasuta fueron atraídos a la longitud de onda de 400 y 420 nm comparado a C. stephanoderis. A 380 nm, las avispas P. coffea y C. stephanoderis mostraron la más alta respuesta en comparación con las hembras de P. nasuta. Cuando las avispas que no eligieron fueron excluidas del análisis, nosotros observamos otras diferencias entre las especies de parasitoides. Por ejemplo, P. coffea fue más atraído a 490–540 nm que a 570 nm, mientras que los betylidos no discriminaron entre 490–540 nm o 570 nm. Nuestros resultados son discutidos en relación a posibles implicaciones asociadas con la visión de estas especies de parasitoides.

Resumen en inglés

The African parasitoids Cephalonomia stephanoderis Waterston (Bethylidae: Hymenoptera), Prorops nasuta Betrem (Bethylidae: Hymenoptera), and Phymastichus coffea LaSalle (Eulophidae: Hymenoptera) are biological control agents of the coffee berry borer (Coleoptera: Curculionidae). In this study, we investigated in laboratory the female behavioral responses of these parasitoids to 14 different wavelengths (340–670 nm) against a control (570 nm, yellow). When nonchooser females were included in the analysis, none parasitoids species showed a preference between 340, 350, 370, 460, 490, 520, 540, 590, 640, and 650 nm with respect to the control wavelength. In contrast, the three species of parasitoids were more attracted to wavelengths of 380, 400, and 420 nm than the control wavelength. Phymastichus coffea and P. nasuta were more attracted to the wavelength of 400 and 420 nm compared to C. stephanoderis. At 380 nm, P. coffea and C. stephanoderis wasps showed the higher responses in comparison to P. nasuta females. When nonchooser wasps were excluded from the analysis, we observed other differences among the parasitoid species. For instance, P. coffea were more attracted to 490–540 nm than to 570 nm, whereas the bethylids did not discriminate between 490–540 nm or 570 nm. Our results are discussed in relation to possible implications associated with the vision of these parasitoid species.

Resumen en inglés

diversity of arthropods (myrmecophiles) thrives within ant nests, many of them unmolested though some, such as the specialized Eucharitidae parasitoids, may cause direct damage to their hosts. Ants are known to discriminate between nestmates and non-nestmates, but whether they recognize the strength of a threat and their capacity to adjust their behavior accordingly have not been fully explored. We aimed to determine whether Ectatomma tuberculatum ants exhibited specific behavioral responses to potential or actual intruders posing different threats to the host colony and to contribute to an understanding of complex ant-eucharitid interactions. Behavioral responses differed significantly according to intruder type. Ants evicted intruders that represented a threat to the colony’s health (dead ants) or were not suitable as prey items (filter paper, eucharitid parasitoid wasps, non myrmecophilous adult weevils), but killed potential prey (weevil larvae, termites). The timing of detection was in accordance with the nature and size of the intruder: corpses (a potential source of contamination) were detected faster than any other intruder and transported to the refuse piles within 15 min. The structure and complexity of behavioral sequences differed among those intruders that were discarded. Workers not only recognized and discriminated between several distinct intruders but also adjusted their behavior to the type of intruder encountered.

Our results confirm the previously documented recognition capabilities of E. tuberculatum workers and reveal a very fine-tuned intruder discrimination response. Colony- level prophylactic and hygienic behavioral responses through effective removal of inedible intruders appears to be the most general and flexible form of defense in ants against a diverse array of intruders. However, this generalized response to both potentially lethal and harmless intruders might have driven the evolution of ant-eucharitid interactions, opening a window for parasitoid attack and allowing adult parasitoid wasps to quickly leave the natal nest unharmed.

Resumen en inglés

The Ichneumonoidea is a vast and important superfamily of parasitic wasps, with some 60,000 described species and estimated numbers far higher, especially for small-bodied tropical taxa. The superfamily comprises two cosmopolitan families - Braconidae and Ichneumonidae - that have largely attracted separate groups of researchers, and this, to a considerable extent, has meant that understanding of their adaptive features has often been considered in isolation. This book considers both families, highlighting similarities and differences in their adaptations. The classification of the whole of the Ichneumonoidea, along with most other insect orders, has been plagued by typology whereby undue importance has been attributed to particular characters in defining groups. Typology is a common disease of traditional taxonomy such that, until recently, quite a lot of taxa have been associated with the wrong higher clades. The sheer size of the group, and until the last 30 or so years, lack of accessible identification materials, has been a further impediment to research on all but a handful of ‘lab rat’ species usually cultured initially because of their potential in biological control. New evidence, largely in the form of molecular data, have shown that many morphological, behavioural, physiological and anatomical characters associated with basic life history features, specifically whether wasps are ecto- or endoparasitic, or idiobiont or koinobiont, can be grossly misleading in terms of the phylogeny they suggest. This book shows how, with better supported phylogenetic hypotheses entomologists can understand far more about the ways natural selection is acting upon them.

This new book also focuses on this superfamily with which the author has great familiarity and provides a detailed coverage of each subfamily, emphasising anatomy, taxonomy and systematics, biology, as well as pointing out the importance and research potential of each group. Fossil taxa are included and it also has sections on biogeography, global species richness, culturing and rearing and preparing specimens for taxonomic study. The book highlights areas where research might be particularly rewarding and suggests systems/groups that need investigation. The author provides a large compendium of references to original research on each group. This book is an essential workmate for all postgraduates and researchers working on ichneumonoid or other parasitic wasps worldwide. It will stand as a reference book for a good number of years, and while rapid advances in various fields such as genomics and host physiological interactions will lead to new information, as an overall synthesis of the current state it will stay relevant for a long time.

Resumen en inglés

Eucharitidae are parasitoids that use immature stages of ants for their development. Kapala Cameron is the genus most frequently collected in the Neotropics, but little is known about the biology and behavior of any of the species of this genus. We aimed to evaluate the effect of habitat type on eucharitid parasitism and to contribute to the knowledge of the host-parasite relationship between Kapala sp. and the poneromorph ant Ectatomma ruidum (Roger) in Colombia. Twenty E. ruidum colonies were extracted from two different habitat types (woodland and grassland), and larvae and cocoons (pupae) were examined in search for parasitoids in different stages of development. Globally, 60% of the colonies were parasitized, with 1.3% of larvae and 4% of pupae parasitized. Planidia (first-instar larvae), pupae, and adults of the parasitoid were observed. All of the pupae and adult parasitoids belonged to Kapala iridicolor Cameron. All the colonies collected in the woodlands were parasitized and contained more parasitized larvae (2%) and parasitized cocoons (8%) than those collected in grasslands (4/12 parasitized colonies, 0.5% parasitized larvae, 0.8% parasitized cocoons). The relationship observed between habitat type and parasitism prevalence is a novel aspect of the study of eucharitid impact on ant host populations.

Resumen en español

Numerosos casos de asociaciones con hormigas han sido reportados para avispas de la familia Encyrtidae con anterioridad. Sin embargo, en la mayoría de estos casos, las asociaciones son indirectas (interferencia), a través del parasitismo primario de insectos trofobiontes (Coccoidea) que las hormigas explotan y protegen. Los casos de parasitismo directe sospechados son raros y ningún ataque directo por encírtidos sobre hormigas ha sido demostrado hasta la fecha. Aquí compilamos todos los casos conocidos de asociaciones entre avispas de la familia Encyrtidae y hormigas, y reportamos el primer registro de verdadero parasitismo primario de hormigas para esta familia. De dos colonias de la hormiga ponerina arbórea Pachycondyla goeldii (Forel) de Guyana Francesa que se examinaron, una tenía 3 pupas parasitadas por machos y hembras de un diminuto Encyrtidae gregario, identificado como Blanchardiscus pollux Noyes, y 2 pupas más presentaban señales de pararasitismo. Este primer registro de hospedero conocido para el género Blanchardiscus, el cual siempre ha sido considerado cercano a otros géneros de encírtidos parasitando escamas, tiende a apoyar la hipótesis de una deriva progresiva del parasitismo desde los mirmecófilos hacia las hormigas. Este reporte permite incrementar a 9 el número de familias de avispas parasitoides conocidas por parasitar a hormigas. Es muy probable que el examen cuidadoso de otras especies de hormigas arbóreas, en particular aquellas involucradas en las construcción de jardínes de hormiga o de nidos tejidos, lleve a la detección de nuevas asociaciones entre hormigas y parasitoides.

Resumen en inglés

Numerous cases of associations of encyrtid wasps with ants have already been reported. In the majority of these cases, however, wasps are associated only indirectly with ants (interference associations) through primary parasitism of the trophobionts (Coccoidea), which are exploited and protected by ants. Suspected direct parasitism cases are unusual and no direct attack of encyrtids on ants has ever been demonstrated. Here we provide both a revised list of all known cases of associations between encyrtid wasps and ants, and a report of the first record of a true primary encyrtid parasitoid of ants. Of two colonies of the arboreal ponerine ant, Pachycondyla goeldii (Forel), examined from French Guiana, one had 3 pupae parasitized by males and females of a gregarious, minute encyrtid wasp species, identified as Blanchardiscus pollux Noyes, and 2 other cocoons presented evidence of pararasitism. This first host record for the genus Blanchardiscus, which has always been placed near other genera that parasitize scale-insects, supports a hypothesis of a shift from a myrmecophilous host to an ant host. Our findings increase to 9 the number of parasitoid wasp families known to attack ants as primary hosts. A closer examination of other arboreal ants, particularly those involved in ant-garden building and nest weaving, will certainly yield new ant-parasitoid associations.

Resumen en inglés

The bethylid wasps Cephalonomia stephanoderis Betrem and Prorops nasuta Waterston are parasitoids of the coffee berry borer, Hypothenemus hampei (Ferrari), the most serious insect pest of coffee worldwide. Recent studies on the host location behaviour of these parasitoids have shown that females are attracted to volatile compounds released by immature stages and dust/frass of H. hampei. Also, these studies have reported that the locomotory behaviour of parasitoids is influenced by contact chemical cues from host dust/frass. In this study, we investigated the responses of females of both species to volatiles and contact cues from dust/frass from different sources. Volatiles from dust/frass from H. hampei-infested coffee and maize infested with Sitophilus sp were attractive to P. nasuta females. In contrast, C. stephanoderis females were only attracted to the volatiles from dust/frass from H. hampei-infested coffee.

Volatiles from an artificial diet used for rearing H. hampei were not attractive to females of both species. The effect of methanolic extracts from dust/frass from different sources on the patch-searching time of parasitoids was analysed using the Ethovision software. P. nasuta females spent more time in the patches treated with extracts of dust/frass from H. hampei-infested berries, artificial diet, and from maize infested with Sitophilus sp than on patches treated with dry coffee extract or solvent control. C. stephanoderis females spent more time on patches treated with dust/frass extracts from H. hampei-infested berries and artificial diet than on patches treated with an extract of dust/frass from maize infested with Sitophilus sp, an extract of dry coffee, and methanol control.
