Contrasting reproductive traits of competing parasitoids facilitate coexistence on a shared host pest in a biological control perspective. [PDF]
Pest Manag Sci, 2022 This study examined the role played by parasitoid reproductive capacities and host clutch size on the outcome of extrinsic competition between Trissolcus basalis and Ooencyrtus telenomicida, two egg parasitoids of the pest Nezara viridula. Results showed that contrasting reproductive capacities of two competing egg parasitoid species facilitate ...

A temporal trophic shift from primary parasitism to facultative hyperparasitism during interspecific competition between two coevolved scelionid egg parasitoids. [PDF]
Ecol Evol, 2021 Competition between two co‐evolved scelionid egg parasitoids was evaluated to better understand the competitive strategies that allow these two species to coexist on the same host. Not only was Trissolcus cultratus the superior intrinsic competitor when it was the first species to parasitize an egg mass, but it was also able to develop as a facultative

Reproductive attributes and functional response of Anastatus japonicus on eggs of Antheraea pernyi, a factitious host. [PDF]
Pest Manag Sci, 2022 Single 1‐day‐old mated Anastatus japonicus females exhibited a type II functional response to increasing host densities (1–50 Antheraea pernyi eggs), with an inverse host density‐dependent pattern of percent parasitism. The upper limit to the daily attack rate was estimated as 7.6 Antheraea pernyi eggs.

Entomologia Experimentalis et Applicata, Volume 171, Issue 10, Page 739-744, October 2023., 2023 The Mediterranean ants Crematogaster scutellaris and Tapinoma magnum (Hymenoptera: Formicidae) can significantly increase the mortality of nymphs of the stink bug Nezara viridula (Hemiptera: Pentatomidae). At the same time, they do not damage the eggs and do not interfere with the parasitization activity of Trissolcus basalis (Hymenoptera: Scelionidae),

Journal of Morphology, Volume 282, Issue 11, Page 1616-1658, November 2021., 2021 The sexual dimorphism of ants is understudied, relative to the within‐sex polyphenism of females. Through comparison of male and female Dorylus, we discovered that the reproductives share specific head features to the exclusion of workers—a previously unrecorded phenomenon which suggests that there is an additional axis of morphogenetic variation in ...

Systematic Entomology, Volume 46, Issue 4, Page 1088-1113, October 2021., 2021 We use a combination of morphological, multi‐locus Sanger sequencing, and whole‐genome sequences to infer the phylogeny of the parasitoid wasp superfamily Platygastroidea. The ancestral hosts of platygastroids were the eggs of Orthoptera. Numerous subsequent host shifts have led to the use of other hosts from an additional eight insect orders and ...

Parasitoids of the invasive Nezara viridula (Linnaeus) in Bulgaria [PDF]
Journal of Central European Agriculture, 2022 The southern green stink bug Nezara viridula (Linnaeus) is a polyphagous species that causes economic damages to many crops in Bulgaria. The aim of this study was to identify the parasitoid species that could suppress the populations of Nezara viridula ...

Tiny but mighty? Overview of a decade of research on nectar bacteria. [PDF]
New PhytolSummary An emerging focus of research at the intersection of botany, zoology, and microbiology is the study of floral nectar as a microbial habitat, referred to as the nectar microbiome, which can alter plant–pollinator interactions. Studies on these microbial communities have primarily focused on yeasts, and it was only about a decade ago that ...

Complementary effects of pollination and biocontrol services enable ecological intensification in macadamia orchards. [PDF]
Ecol ApplAbstract In many crops, both pollination and biocontrol determine crop yield, whereby the relative importance of the two ecosystem services can be moderated by the landscape context. However, additive and interactive effects of pollination and biocontrol in different landscape contexts are still poorly understood. We examined both ecosystem services in

Pesquisa Agropecuária Brasileira, 2012 O objetivo deste trabalho foi avaliar a influência de voláteis de soja, induzidos pela herbivoria dos percevejos Euschistus heros e Nezara viridula, no comportamento de busca de hospedeiros dos parasitoides Telenomus podisi e Trissolcus basalis.
