A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

open access: yesInsect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Triangular fecundity function and ageing in ladybird beetles [PDF]

open access: yesEcological Entomology, 2002
Abstract 1. In insects, the age schedules of fecundity tend to be triangular and this has been attributed more to temporal patterns of mortality than to fecundity. The objective of the work reported here was to test the assumption that senescence shapes the fecundity function in ladybird beetles, and in ...

Comparing time‐lapse photography and traditional human observation in collecting crop pollinator visitation data Ajastetun valokuvauksen ja perinteisen suoran havainnoinnin vertailu kerättäessä tietoa pölyttäjien kukkakäynneistä viljelykasveilla

open access: yesAgricultural and Forest Entomology, EarlyView.
Time‐lapse photography with commercially available trail cameras provides a competitive alternative to direct human observations for documenting pollinator flower visits, but its performance varies between crops. In apple, the cameras recorded more diverse pollinator assemblages than the human observer due to larger temporal coverage of the camera ...

New data on ladybird beetles (Coleoptera: Coccinellidae) of Wigry National Park [PDF]

open access: yes, 2016
Ladybird beetles were surveyed in 2014-2016 in Wigry National Park (NE Poland). Thirty three species were recorded. The most abundant were Subcoccinella vigintiquatuorpunctata (20% of all ladybird individuals) and Coccinella quinquepunctata (17% of all ...

Automatic Potato Crop Beetle Recognition Method Based on Multiscale Asymmetric Convolution Blocks

open access: yesAgronomy
Five beetle species can occur in potato fields simultaneously, including one quarantine pest (the Colorado potato beetle (CPB)), one phytophagous pest (the 28-spotted potato ladybird beetle), and three predatory ladybird beetles (the 7-spotted lady ...

Storying Multispecies‐Life‐and‐Death: Becoming‐Grief‐Able in Educational Spaces for Post‐Necrocene Futures

open access: yesChildren &Society, EarlyView.
ABSTRACT We situate this article from/with/in the Necrocene, a geological period marked by the systematic production of human and more‐than‐human death to an extent that ecological destruction, extinction, loss and harm have become a structural feature of modern life.

Glyphosate residues in soil alter herbivore‐induced plant volatiles and affect predatory insect behaviour

open access: yesPlant Biology, EarlyView.
Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.

Geographical proliferation of ongoing novel host use by the herbivorous ladybird beetle Henosepilachna vigintioctopunctata (Coleoptera: Coccinellidae)

open access: yesEntomological Science, Volume 29, Issue 4, December 2026.
The geographical extent of occurrence of the Solanaceae‐feeding Henosepilachna vigintioctopunctata on the novel fabaceous host Centrosema molle and the ability of larvae from several beetle populations to develop on C. molle were investigated to depict the incipient phase in the speciation continuum of herbivorous ladybird beetles.

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2298-2314, September 2026.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.
