Description of a New Cruranthura Species from the Miyako Islands, Japan, with Its DNA Barcode (Isopoda: Anthuroidea: Paranthuridae)

Species Diversity
We describe Cruranthura viridis sp. nov. based on four specimens collected from the subtidal zone near Irabu Island, Miyako Islands, Okinawa, Japan. This species differs from four congeneric species in having (1) small body size (2.53–3.38 mm), (2) moss ...

Diversification of insects since the Devonian: a new approach based on morphological disparity of mouthparts

Scientific Reports, 2018
The majority of the analyses of the evolutionary history of the megadiverse class Insecta are based on the documented taxonomic palaeobiodiversity. A different approach, poorly investigated, is to focus on morphological disparity, linked to changes in ...

Comparative morphology and evolutionary implications of larval mouthparts in ten lineages of Scarabaeoidea (Coleoptera) [PDF]

Arthropod Systematics & Phylogeny
Larvae of the megadiverse Scarabaeoidea play important economic and ecological roles, and their mouthparts provide valuable morphological clues for species identification and dietary inference.

Evidence for a defensive ceiling in the effectiveness of plant silicon defences against an insect herbivore

Ecological Entomology, EarlyView.
Silicon‐mediated resistance in wheat reaches a defensive plateau; accumulating silicon beyond 2mM provides no additional benefit for suppressing insect herbivore relative growth rates. Silicon supplementation significantly increases wheat biomass and effectively ameliorates plant mass losses caused by Helicoverpa armigera herbivory. Lower mandible wear

Caste‐Associated Social Context Modulates Behavioural Interactions With Insecticide‐Exposed Individuals in Nasutitermes corniger (Termitidae: Nasutitermitinae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Termites are eusocial insects that maintain cohesion and exchange information through frequent physical interactions among nestmates. This social organisation underlies the principle of horizontal insecticide transfer, which is widely exploited as a termite control strategy.

Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination

Journal of Integrative Plant Biology, EarlyView.
Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

Plant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

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.

First observation on the antennal cleaning behaviour in Archaeognatha (Insecta) [PDF]

Deutsche Entomologische Zeitschrift
Antennal cleaning behaviour in Archaeognatha is documented for the first time, supported by photographs and video observations of a male Petrobiellus akkesiensis (Machilidae, Petrobiellinae) collected from Hokkaido, Japan.

Impact of cultural practices on two‐spotted spider mite (Tetranychus urticae Koch) infestation in tomato cultivation in the Central Rift Valley of Ethiopia

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract The two‐spotted spider mite (TSSM; Tetranychus urticae Koch) is a major pest of tomato (Solanum lycopersicum L.), causing substantial yield and quality losses in Ethiopia and worldwide. The present study evaluated the impact of tomato branch pruning and trellising on TSSM populations and yield in the Central Rift Valley tomato production area ...
