Surveys in northern Utah for egg parasitoids of Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) detect Trissolcus japonicus (Ashmead) (Hymenoptera: Scelionidae) [PDF]

open access: yesBiodiversity Data Journal, 2020
The highly polyphagous and invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), has become a significant insect pest in North America since its detection in 1996.

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

open access: yesAdvanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Field Control Effect of Telenomus remus Nixon and Trichogramma chilonis Ishii Compound Parasitoid Balls against Spodoptera frugiperda (J. E. Smith)

open access: yesInsects
Although the release of egg parasitoids has proven to be an effective strategy for the control of the fall armyworm (FAW), a single egg parasitoid, however, has exposed some deficiencies in practice, and it is worthwhile to explore whether the ...

Loss, persistence and reversal of phenotypic traits

open access: yesBiological Reviews, EarlyView.
ABSTRACT The irreversibility of complex trait loss has long been a tenet of evolutionary biology. However, this idea is increasingly at odds with the numerous documented exceptions across the Tree of Life. We synthesise this growing body of evidence across a diverse array of taxa and traits, exploring the evolutionary conditions that enable ...

Population fluctuation of Spodoptera frugiperda eggs and natural parasitism by Trichogramma in maize - doi: 10.4025/actasciagron.v35i3.16769

open access: yesActa Scientiarum. Agronomy, 2013
This study aimed to evaluate the fluctuation of S. frugiperda eggs and natural parasitism by Trichogramma and identify and quantify parasitoid species in maize fields in the state of Rio Grande do Sul, Brazil.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

First record of Gonatocerus litoralis (Haliday) (Hymenoptera: Mymaridae) from Anoplotettix putoni Ribaut (Hemiptera: Cicadellidae)

open access: yesJournal of Entomological and Acarological Research, 2013
The mymarid Gonatocerus litoralis (Haliday) is recorded for the first time as an egg parasitoid of the leafhopper Anoplotettix putoni Ribaut. A study of the main morphological characters shows unusual variation in distribution of the multiporous plate ...

Host Sex Discrimination by an Egg Parasitoid on Brassica Leaves

open access: yesJournal of Chemical Ecology, 2011
Egg parasitoids are able to find their hosts by exploiting their chemical footprints as host location cues. In nature, the apolar epicuticular wax layer of plants that consists of several classes of hydrocarbons serves as the substrate that retains these contact kairomones. However, experiments on chemical footprints generally have used filter paper as

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Paratelenomus anu Rajmohana, Sachin & Talamas (Hymenoptera, Scelionidae): description and biology of a new species of phoretic egg parasitoid of Megacopta cribraria (Fab.) (Hemiptera, Plataspidae) [PDF]

open access: yesJournal of Hymenoptera Research, 2019
Paratelenomus anu Rajmohana, Sachin & Talamas, sp. nov. (Hymenoptera: Scelionidae) is an egg parasitoid of the kudzu bug, Megacopta cribraria (Fab.) (Hemiptera: Plataspidae). It is morphologically and genetically distinct from P.
