The genus Nealiolus Mason, 1974 (Hymenoptera: Braconidae, Brachistinae) is recorded for the first time in the Atlantic forest remnants and traditional cocoa agroforests, Theobroma cacao (Malvaceae) in the northeastern Brazilian region. A new species Nealiolus seb Silva, Shimbori and Fernandes sp. n. is described and named in honor of the "Sociedade...
Abstract: In South America, the resident pupal parasitoid Trichopria anastrephae Costa Lima (Hymenoptera: Diapriidae) is a potential biological control agent of the pest Drosophila suzukii Matsumura (Diptera: Drosophilidae). In the present study, we (1) examined the behavior of T. anastrephae towards diferent host (D. suzukii) and host-substrate (s...
Global change is affecting plant-insect interactions in agroecosystems and can have dramatic consequences on yields when causing non-targeted pest outbreaks and threatening the use of pest natural enemies for biocontrol. The vineyard agroecosystem is an interesting system to study multi-stress conditions: on the one hand, agricultural intensificati...
The parasitoid wasp Leptopilina boulardi is a major natural parasite of Drosophila melanogaster. However, the regulation of Drosophila humoral immunity against parasitoids is not clearly illustrated. In this thesis, I investigated the humoral immune mechanisms underlying Drosophila resistance to parasitoid infections, as well as the evolution of hu...

Before the introduction of Bactrocera dorsalis (Hendel) to sub-Saharan Africa, Ceratitis cosyra (Walker) was economically the most important pest in mango farming. Its native natural enemy, the solitary parasitoid Psyttalia cosyrae (Wilkinson), played a crucial role in C. cosyra bio-control, later complemented by the exotic parasitoids Diachasmimor...

The brinjal fruit and shoot borer (BFSB), Leucinodes orbonalis Guenée (Lepidoptera: Crambidae), is a very detrimental pest that causes significant economic losses to brinjal crop worldwide. Infested brinjal fruits were collected from vegetable fields located at the ICAR-Indian Agricultural Research Institute (ICAR-IARI), New Delhi, India, during tw...
The objective of this work was to evaluate the infestation of the flow-er-bud-fly in different sizes of flower buds and to relate the infestation with the plant phenology and weather variables. In the 2017/18 and 2018/19 seasons, flower buds of plants were collected to obtain pupae, adults, and parasitoids in a commercial orchard of sour passion fr...
Depuis une quinzaine d’années, l’étude du rôle des symbiontes bactériens présents chez certains insectes passionne les scientifiques. Chez le puceron, il a été clairement établi que des bactéries symbiotiques conféraient à leur hôte une protection contre un important ennemi naturel utilisé en lutte biologique : les parasitoïdes. Cependant, l’évolut...

In many parts of the world, chemical pesticides are the primary method of pest control in maize ( Zea mays L .) crops. Concerns about the negative consequences of chemical pesticide use on people’s health and the environment, as well as the emergence of insecticide resistance, have accelerated attempts to discover alternatives that are effective, l...

Biological control and taxonomy are continuously developing fields with remarkable impacts on society. At least 80 years of literature have documented this relationship, which remains essentially the same in its mutualistic nature, as well as in its major challenges. From the perspective of Brazilian taxonomists, we discuss the impacts of important...
