Release strategies of Telenomus podisi for control of Euschistus heros: a computational modeling approach [PDF]

open access: yesPest Management Science, 2022
AbstractBACKGROUNDThe egg‐parasitoid wasp Telenomus podisi has received attention as a biological‐control agent for one of the most important soybean pests in Brazil, the stink bug Euschistus heros. As yet, no studies have conclusively established strategies for the release of T. podisi. We developed a computational model using cellular automata in the

Attenuation of ultraviolet (UV) radiation does not impede host location in egg parasitoids with positive UV phototaxis

open access: yesEcological Entomology, Volume 48, Issue 4, Page 445-457, August 2023., 2023
We investigated how ultraviolet (UV) radiation affects the foraging behaviours of two species of female stink bug egg parasitoids. UV‐exposed microhabitats were attractive to parasitoids and reduced their daily walking activity in the laboratory. UV attenuation did not reduce parasitoid host discovery and host exploitation rates on soybean plants in ...

BeeDNA: Microfluidic environmental DNA metabarcoding as a tool for connecting plant and pollinator communities

open access: yesEnvironmental DNA, Volume 5, Issue 1, Page 191-211, January 2023., 2023
Microfluidic metabarcoding of eDNA derived from the surfaces of flowers was able, to a degree, to document pollinator communities. Abstract Pollinators are declining globally, and this loss can reduce plant reproduction, erode critical ecosystem services and resilience, and drive economic losses.

Differential impacts of pesticides on Euschistus heros (Hem.: Pentatomidae) and its parasitoid Telenomus podisi (Hym.: Platygastridae). [PDF]

open access: yesSci Rep, 2019
AbstractEuschistus heros (Fabricius) (Hemiptera: Pentatomidae) primarily attack the pods and seeds of soybean plants, causing severe economic losses in Neotropical Region, and chemical control is essential to avoid these losses. Thus, insecticides more effective against this pest and less toxic to Telenomus podisi Ashmead (Hymenoptera: Platygastridae) -

Telenomus podisi Parasitism on Dichelops melacanthus and Podisus nigrispinus Eggs at Different Temperatures [PDF]

open access: yesFlorida Entomologist, 2019
Dichelops melacanthus (Dallas) (Heteroptera: Pentatomidae) is the most important stink bug species that feeds on maize in South America, and it is frequently controlled with chemical pesticides. As an alternative, more sustainable management strategies can be applied, among which the egg parasitoid Telenomus podisi Ashmead (Hymenoptera: Scelionidae ...

Insects in agroecosystems – an introduction

open access: yesEntomologia Experimentalis et Applicata, Volume 168, Issue 1, Page 3-6, January 2020., 2020
Agroecology is the study of linkages in agricultural systems and it derives from the need to understand and restore natural connections and ecological complexity to control insect and other pest populations. The present special issue addresses a rich variety of agroecosystems spanning the globe, involving the roles of a range of insects on a great many

Defesas induzidas por herbivoria e interações específicas no sistema tritrófico soja-percevejos-parasitoides de ovos

open access: yesPesquisa 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.

Transcriptome-Based Identification of Highly Similar Odorant-Binding Proteins among Neotropical Stink Bugs and Their Egg Parasitoid. [PDF]

open access: yesPLoS ONE, 2015
Olfaction plays a fundamental role in insect survival through resource location and intra and interspecific communications. We used RNA-Seq to analyze transcriptomes for odorant-binding proteins (OBPs) from major stink bug pest species in Brazil ...
