Introduction
My main interest is the study of the biology and ecology of parasitoid (Hymenoptera and Diptera), in particular those associated with phytophagous hemipteran pests (Pentatomidae). My studies have focused on analyzing the dynamics of the interactions between the pest and its natural enemies, with particular interest in multispecies interactions as multiparasitism. Through laboratory tests and field experiences, I investigate the performance of different parasitoids that share a common host.

Many animals lay their eggs in clusters. Eggs on the periphery of clusters can be at higher risk of mortality. We asked whether the most commonly occurring clutch sizes in pentatomid bugs could result from geometrical arrangements that maximize the proportion of eggs in the cluster's interior. Although the most common clutch sizes do not correspond...
Article
Invasive stink bugs (Hemiptera: Pentatomidae) are responsible for high economic losses to agriculture on a global scale. The most important species, dating from recent to old invasions, include Bagrada hilaris (Burmeister), Halyomorpha halys (Stål), Piezodorus guildinii (Westwood), Nezara viridula (L.), and Murgantia histrionica (Hahn). Bagrada hil...
Article
When searching for hosts, parasitoids may experience competition between adults exploiting the same host (extrinsic), or between larvae developing inside the host (intrinsic competition). Differences in competitive abilities like host location and resource utilisation promote coexistence. In this sense, extrinsically superior parasitoids better loc...

Several parasitoids attacking the same host may lead to competition. Adult parasitoids’ abilities to find, parasitize and defend hosts determine resource’s retention potential. In soybean, two egg parasitoid species, Telenomus podisi and Trissolcus urichi (Hymenoptera: Platygastridae), compete on the egg masses of Piezodorus guildinii (Hemiptera: P...
Conference Paper
Full-text available
In the search for hosts, parasitoids may experience competition between adults exploiting the same host (extrinsic), or between larvae developing inside the host (intrinsic competition). An intrinsically inferior competitor may coexist with an intrinsically superior one, if it has better abilities to locate host. Adult parasitoids´ abilities to fin...
Article
A trade-off is a relationship between two life history characteristics principally reproduction and adult longevity that are fundamental in predicting the optimal life history in any given environment. Mating is indispensable for sexual reproduction, but also can impose risks to females. Nevertheless, in the majority of insects, females allow multi...
Article
Aphids are common herbivores in the strawberry crop that can reduce plant vigor and fruit quality and also transmit viruses. Aphid species prefer diverse plant organs, which represent particular habitats of different quality for aphids and for the development of natural enemies’ populations. Different habitat units (young leaves, mature leaves, bud...

Piezodorus guildinii (Hemiptera: Pentatomidae) is an important soybean pest, and one of its main natural enemies is Telenomus podisi (Hymenoptera: Platygastridae). To rear the parasitoid is constrained by hosts' quality, which deteriorates after few generations in laboratory, so cold-stored host eggs utilization could be a useful tool for augmentat...
Article
Full-text available
Parasitoid's performance is subject to parasitism decisions influenced by host quality and parasitoid's age. We evaluated parasitism, emergence, and the progeny sex ratio proportions of Telenomus podisi (Ashmead), Trissolcus urichi (Crawford), and Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae) females of different age attacking Piezod...
Article
Piezodorus guildinii Westwood and Nezara viridula (L.) (Hemiptera: Pentatomidae) are important soybean pests. P. guildinii causes more injury and is less susceptible to insecticides compared to N. viridula. N. viridula egg parasitoids are well studied; however, little is known about parasitoids of P. guildinii. Alfalfa, soybean and red clover were...
Article
Trissolcus basalis has been used as a biological control agent of its main host, Nezara viridula, in many countries. However, estimations of its functional and numerical responses in the field are lacking. We estimated the density of N. viridula eggs, the proportion of parasitized N. viridula eggs, and the number of T. basalis adults/trap in the fi...
Article
Egg masses of Nezara viridula (L.) are commonly parasitized by Trissolcus basalis (Woll.), and we investigated the role of size of egg masses on parasitization by T. basalis . Sentinel egg masses were exposed to parasitism in the field for 6–7 days, when they were collected for evaluation of parasitoid emergence. We recorded the number of eggs per...

Among the herbivorous arthropods that feed on strawberry, the most important are the two-spotted spider mite (TSSM), Tetranychus urticae Koch, and several species of aphids. Mites and aphids belong to different guilds that coexist in the field and feed on the undersides of strawberry leaflets. However, the occurrence of large numbers of individuals...
Thesis
The soybean crop has undergone a major expansion in several countries over the past 10 years. Phytophagous hemipterans of the family Pentatomidae, known as bugs, cause significant damage on seeds due to their feeding habits. In Argentina, the most important species are Piezodorus guildinii, Nezara viridula, Edessa meditabunda and Dichelops furcatus...
Article
Multiparasitism involves competition between larvae inside the host. Telenomus podisi (Ashmead) and Trissolcus urichi (Crawford) (Hymenoptera: Platygastridae) are solitary egg parasitoids of Piezodorus guildinii Westwood (Hemiptera: Pentatomidae), an important soybean pest. Egg masses partially parasitized by one species were offered to females of...
Article
We developed and validated a management plan for Tetranychus urticae in strawberries, based on the natural control exerted by Neoseiulus californicus and on acaricide applications made only when necessary. The plan has two components: a sampling protocol and a decision chart. Systematic presence–absence sampling of active T. urticae and N. californ...

Los trabajos realizados en la Estación Experimental Julio Hirschhorn se enmarcan en el plan de tesis doctoral de la Lic. M. Fernanda Cingolani, y aportaron al estudio de dos de los objetivos planteados en dicha tesis: 1. Estimar la eficiencia en la detección de posturas, la eficiencia y el impacto del parasitismo de Trissolcus basalis, Trissolcus u...
Article
The aim of this work is to analyze the institutional and political framework in which the University Extension works. For this purpose, the politics of the Extension Department of the UNLP and the Natural Sciences and Museum College were analyzed. Though concrete actions to promote its development were observed in both institutions, the lack of hie...
Article
The main pest of the strawberry crops is the “Two spotted spider mite”, Tetranychus urticae. Its control consists of preventive applications of acaricides, wich are many times unnecessary. In the crops also is an predator mite, Neoseiulus californicus, that can control the pest. Our objective was to transfer to the small and medium growers, of the...
Article
The aim of this work is to introduce different theoretical and educational approaches by which rural Extension can be conceived. In this case, these approaches are then applied to make a self-criticism of the carried out extension activities. We see that we often reproduce old practices of Extension, without obtaining the appropriation of the knowl...

Project
The knowledge about the economic importance of Argentinean Heteroptera is fragmented, and only refers to isolated species in each particular crop. The aim of this project is provide an integral vision on the distribution, host plants, natural enemies, and biology to the important and less important economic species of Heteroptera in Argentina.
