Severe Tick Infestation and Haemogregarina spp. Infection in a Captive African Rock Python (Python sebae): A Clinical and Parasitological Case from Nigeria

open access: yesVeterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Heavy Amblyomma latum infestation transmitted haemoparasites to a captive African rock python, causing anorexia, facial swelling and dysecdysis. Manual tick removal, povidone‐iodine cleansing and a single oral dose of ivermectin cleared both ecto‐ and haemoparasites.

Identification and Biocontrol of Mindarus japonicus Takahashi, a New Pest of Abies koreana E.H.Wilson Using Bacillus velezensis CE 100

open access: yesEntomological Research, Volume 56, Issue 7, July 2026.
ABSTRACT Subalpine conifers such as Abies koreana E.H.Wilson (Korean fir) play a significant ecological role but are increasingly endangered due to the effects of climate change, including the high prevalence of insect pests. This study identified for the first time, a notorious aphid pest on newly developed needles and twigs of A.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Offspring Dependency Is Not Reflected in the Social Immunity of Three Burying Beetle Species

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 625-638, July 2026.
Nicrophorus pustulatus, Nicrophorus vespilloides, and Nicrophorus orbicollis are three burying beetle species that differ both in their ecology and in the dependency of their offspring on parental care. This gradient of offspring dependency might be reflected in the parents' social immunity capabilities and/or investment.

Hairy Roadblock: Stem Trichomes Impede Herbivore Movement in a Species and Instar‐Dependent Manner

open access: yesJournal of Applied Entomology, Volume 150, Issue 6, Page 728-735, July 2026.
ABSTRACT Plants have evolved to deploy a vast set of defence mechanisms against insect herbivores, including physical barriers like leaf trichomes with pre and post ingestive effects. Yet, the role of stem trichomes in plant‐herbivore interactions, particularly mobility dynamics, is poorly understood.

The Mouthparts of Ants

open access: yes, 2001
Ant mandible movements cover a wide range of forces, velocities and precision. The key to the versatility of mandible functions is the mandible closer muscle. In ants, this muscle is generally composed of distinct muscle fiber types that differ in morphology and contractile properties.

Unearthing Mesozoic beetles through micro‐computed tomography: A new family of Archostemata and the first representatives of Ommatidae and †Notocupes from the Crato Formation

open access: yesSystematic Entomology, Volume 51, Issue 3, July‐September 2026.
First formally described Archostemata beetles from the Lower Cretaceous Crato Formation are reported, representing the earliest records of the suborder from western Gondwana. Micro‐computed tomography enabled three‐dimensional reconstruction of partially exposed fossils, revealing previously hidden dorsal and ventral morphological characters relevant ...
