Introduction
I studied mainly the invasive stink bug Bagrada hilaris and one of its native egg parasitoids Gryon gonikopalense, especially their oviposition behavior, and the evaluation of G. gonikopalense as a biocontrol agent in the U.S. Now I'm working on the use of Trissolcus japonicus and T. mistukurii as biocontrol agent of Halyomorpha halys in hazelnut orchards.

Article
The cold storage of host eggs has been utilized in the production of egg parasitoids used in biological control programs. However, similar stockpiling methods can lead to various responses depending on the parasitoid species considered. Hence, standardization of storage methods is difficult. The egg parasitoid Gryon gonikopalense Sharma, is current...
Thesis
In a context of globalization and climate change, more and more insects are becoming invasive, particularly affecting agriculture on a global scale. At the heart of this network of invasions, the United States of America is experiencing the arrival of many species, mainly from Asia. Among them, stink bugs (Pentatomidae) threaten most American agros...

Host detection and parasitism by egg parasitoids involve host chemical recognition, spatial overlapping, and the ability to overcome physical barriers. Within the context of importation biological control, we examined the potential of Gryon gonikopalense (Hym.: Scelionidae), against the stinkbug pest, Bagrada hilaris (Hem.: Pentatomidae). Bagrada i...
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
The pentatomid bug Bagrada hilaris is a severe invasive alien pest of Brassicaceae crops, which first appeared in California in 2008 and is expanding to several southern U.S. states and South America. To answer the demand of growers for sustainable management methods, a biological control program started in 2015. The egg parasitoid Gryon gonikopale...

Phytophagous insects evolving in agroecosystems express numerous defences when faced with myriads of natural enemies. Such defensive traits might impair the effectiveness of biological control relying on these natural enemies, mostly parasitoids. In the case of parasitoid threat, these defences consist of the avoidance of the parasitoid (reduced ex...
Conference Paper
First reported in California in 2008, Bagrada hilaris (Hem.: Pentatomidae), a major pest of Brassicaceae, has now spread to several U.S. states and Mexico. We studied host phylogeography by sequencing CO1 from 20 bagrada populations and determined that Pakistan is the likely origin for invasive US populations. Sentinel host eggs were used to collec...

This proceedings contains papers dealing with issues affecting biological control, particularly pertaining to the use of parasitoids and predators as biological control agents. This includes all approaches to biological control: conservation, augmentation, and importation of natural enemy species for the control of arthropod targets, as well as oth...
Article
Full-text available
Archipelagoes are considered as “natural laboratories” for studying processes that shape the distribution of diversity. The Lesser Antilles provide a favorable geographical context for divergence to occur. However, although morphological subspecies have been described across this archipelago in numerous avian species, the potential for the Lesser A...

Project
Study of several life history traits of the egg parasitoid Gryon sp. (Hymenoptera: Platygastridae), on the North American invasive pest, Bagrada Hilaris (Burmeister) (Hemiptera: Pentatomidae) in order to a better understanding of the life cycle and the rearing process of a potential biocontrol agent of Bagrada Hilaris in the United States.
