A new model formulation for host depletion in parasitoids
(Elsevier, 2023-01)A new model of host depletion in the functional response of parasitoids is presented. Most existing models describe the dynamics of prey consumption as a sequential-memoryless/Markovian process of searching for, handling, ... -
Caso Diagnóstico Nº 10 “Parasitosis gastrointestinal mixta en borregas”
(EEA Bariloche, INTA, 2021-08)En esta edición damos a conocer una presentación clásica de un caso de parasitosis gastrointestinal en borregas de reposición. El sobrepastoreo, como también la falta de diagnóstico y control de las cargas parasitarias en ... -
Classical biological control of an invasive forest pest : a world perspective of the management of Sirex noctilio using the parasitoid Ibalia leucospoides (Hymenoptera: Ibaliidae)
(2015-02)Classical biological control is a key method for managing populations of pests in long-lived crops such as plantation forestry. The execution of biological control programmes in general, as the evaluation of potential ... -
A comparative analysis of host feeding and life-history traits in parasitoid wasps
(2016-05)Feeding in insect parasitoids can have significant implications from behavioral and evolutionary ecology standpoints. Females of many species not only search for hosts to lay their eggs on, but also may use them as a food ... -
Effect of Drosophila suzukii on Blueberry VOC’s: Chemical Cues for a Pupal Parasitoid, Trichopria anastrephae
(Springer, 2021-07)Biocontrol agents such as parasitic wasps use long-range volatiles and host-associated cues from lower trophic levels to find their hosts. However, this chemical landscape may be altered by the invasion of exotic insect ... -
Effect of egg production dynamics on the functional response of two parasitoids
(Plos ONE, 2024-03)Functional response describes the number of hosts attacked by a parasitoid in relation to host densities and plays an important role by connecting behavioral-level processes with community-level processes. Most functional ... -
Food and Host Searching Decisions Made by Ibalia leucospoides (Hymenoptera: Ibaliidae), a Parasitoid of Sirex noctilio (Hymenoptera:Siricidae)
(2012-07)During their adult life, parasitoids—insects that lay eggs in or on other arthropods eventually killing them- spend a significant proportion of their lifetime searching for hosts, this behavior will determine their future ... -
Host selection by Ibalia leucospoides based on temporal variations of volatiles from the hosts’ fungal symbiont
(2016-12)Insect parasitoids locate hosts via reliable and predictable cues such as volatile emissions from hosts and/or host plants. For insects that depend on mutualistic organisms, such as many wood-boring insects, symbiont-derived ... -
Host-related volatile cues used by a parasitoid wasp during foraging for its woodboring host
(Wiley, 2018-12)Parasitoids relymainly on infochemicals to search for their herbivore hosts to oviposit on. Megarhyssa nortoni (Cresson) (Hymenoptera: Ichneumonidae) is a parasitoid of siricid wasp larvae which are concealed inside tree ... -
Influence of competition and intraguild predation between two candidate biocontrol parasitoids on their potential impact against Harrisia cactus mealybug, Hypogeococcus sp. (Hemiptera: Pseudococcidae)
(Springer Nature, 2021-06-28)When two or more parasitoid species, particularly candidates for biocontrol, share the same target in the same temporal window, a complex of behaviors can occur among them. We studied the type of interactions (competition ... -
Influencia de los rasgos de historia de vida y del uso de información en la adquisición de recursos y dispersión en el parasitoide Ibalia leucospoides Hochenwarth (Hymenoptera: Ibaliidae)
(Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2014-07)El objetivo central de esta tesis es estudiar como la selección natural moldea los rasgos de historia de vida y el comportamiento de los animales de acuerdo al entorno ecológico en el que viven. Este marco teórico nos ... -
Intra-host interspecific larval parasitoid competition solved using modelling and bayesian statistics
(Elsevier, 2018-07)Intraguild competition is a complex phenomenon that shapes parasitoid communities. When several species of parasitoids oviposit within the same individual host, a complex phenomenon of larval competitive interaction occurs. ... -
Linking reproductive and feeding strategies in the parasitoid Ibalia leucospoides: does feeding always imply profit?
(2013-05)Adquisición y asignación de recursos a diferentes funciones biológicas a lo largo de la vida tienen fuertes implicaciones para el éxito reproductivo de los animales. Los animales pueden experimentar diferentes condiciones ... -
Modelling the distribution of forest pest natural enemies across invaded areas: Towards understanding the influence of climate on parasitoid establishment success
(Elsevier, 2019-05)Classical biological control is a pest management practice frequently deployed against invasive insects. However, introduced natural enemies too often fail to establish, and this has been partly explained by climatic ... -
Olfactory attraction of the larval parasitoid, Hyposoter horticola, to plants infested with eggs of the host butterfly, Melitaea cinxia
(Entomological Society of America, 2010-01)Parasitoids locate inconspicuous hosts in a heterogeneous habitat using plant volatiles, some of which are induced by the hosts. Hyposoter horticola Gravenhost (Hymenoptera: Ichneumonidae) is a parasitoid of the Glanville ... -
Patch choice from a distance and use of habitat information during foraging by the parasitoid Ibalia leucospoides
(2012-06)1. In environments in which resources are distributed heterogeneously, patch choice and the length of time spent on a patch by foragers are subject to strong selective pressures. This is particularly true for parasitoids ... -
Patch exploitation behaviour by a parasitoid of a forest pest: The influence of host cues and intra- and interspecific interactions
(Wiley, 2024-03)For parasitoids, host foraging is the most significant activity for their reproductive success, as it directly translates into offspring production. Therefore, foraging behaviour and patch-use decisions by parasitoids still ... -
Resident Hymenopteran Parasitoids with Potential Drosophilid Associations in Andean North Patagonia: Implications for the Biological Control of the Spotted Wing Drosophila
(Springer, 2023-09)The spotted wing drosophila, Drosophila suzukii Matsumura, is native to Southeast Asia and has become a serious pest of soft-skinned fruits worldwide. Several control methods are being tested worldwide as part of an ... -
Revisiting the influence of learning in predator functional response, how it can lead to shapes different from type III
(Wiley, 2022-02)Predator/parasitoid functional response is one of the main tools used to study predation behavior, and in assessing the potential of biological control candidates. It is generally accepted that predator learning in prey ... -
Sex, life history and morphology drive individual variation in flight performance of an insect parasitoid
(2017-08)1. The movement of organisms can be driven by multiple factors and has implications for fitness and the spatial distribution of populations. Insects spend a large proportion of their adult lives foraging by flying for ...
