Comparative analysis of immune responses in ovipositing and non‐ovipositing females of European earwig Analyse comparative de la réponse immunitaire avant et après la ponte chez le forficule européen

Physiological Entomology, EarlyView.
Oviposition and care decrease the total haemocyte concentration. Oviposition and care affect haemocyte type proportions. Serratia marcescens challenge does not affect the immune cell parameters. Abstract Reproduction and immunity are essential biological processes that compete for resources and energy.

Defecation in preparation for ecdysis drives microplastic clearance in cricket nymphs

Physiological Entomology, EarlyView.
In preparation for ecdysis, cricket nymphs cease feeding and gradually clear their gut contents via frass production, which removes most ingested MPs from their digestive tract. Following exoskeletal moulting, the foregut lining, including any remaining MPs, is shed and excreted alongside frass approximately 6 h later.

Distribution of Orthoptera across the river valley (Kaluga-Aleksin canyon, European Russia) and their dynamics under the overgrowing of meadows

Nature Conservation Research: Заповедная наука
Orthoptera insects (hereinafter – orthopterans) play a key role in grassland ecosystems and are often used as indicators of their condition. To conserve these insects and to model their habitat preferences, we need to know patterns of their distribution ...

Planted grasslands have equivalent or higher arthropod biomass than native grassland important to nesting Sprague's Pipits (Anthus spragueii) early in the breeding season

Restoration Ecology, EarlyView.
Abstract Introduction Grassland species are declining globally. Sprague's Pipit (Anthus spragueii), a native grassland‐obligate, nests in planted grasslands in some regions. How food resources in planted grassland compare with those in native grassland is important to determine the relative benefits of creating new grassland by seeding cropland with ...

Phylogenetic characteristics of novel Bacillus weihenstephanensis and Pseudomonas sp. to desert locust, Schistocerca gregaria Forskål (Orthoptera: Acrididae)

Egyptian Journal of Biological Pest Control, 2019
Thirty bacterial isolates were isolated from the gut contents of diseased/dead locust. Their pathogenicity was tested against 4th instar nymphs of desert locust, Schistocerca gregaria Forskål (Orthoptera: Acrididae). Two isolates, designated DL2 and DL6,

The Effect of Relevance on Children's Multiple Text Reading: Evidence From Eye Movements

Scandinavian Journal of Psychology, EarlyView.
ABSTRACT We examined how Finnish children read and integrate information across multiple expository texts when given an inquiry task. We were interested in how task‐relevance of text information affects readers' eye movements and whether the eye movements are connected to the quality of an essay written after reading.
