First Descriptions of Larva and Pupa of Bagous claudicans Boheman, 1845 (Curculionidae, Bagoinae) and Systematic Position of the Species Based on Molecular and Morphological Data

open access: yesInsects, 2019
In this paper, the mature larva and pupa of Bagous claudicans are described and illustrated for the first time. Measurements of younger larval instars are also given.

Transcriptomic and Epigenomic Dynamics of Honey Bees in Response to Lethal Viral Infection

open access: yesFrontiers in Genetics, 2020
Honey bees (Apis mellifera L.) suffer from many brood pathogens, including viruses. Despite considerable research, the molecular responses and dynamics of honey bee pupae to viral pathogens remain poorly understood.

Recently Evolved, Stage‐Specific Genes Are Enriched at Life‐Stage Transitions in Flies

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
We discovered that 20%–30% of protein‐coding genes in Drosophila melanogaster and Aedes aegypti are only expressed during specific stages of development. Surprisingly, many of these stage‐specific genes are newly evolved, unique to flies and mosquitoes, shedding light on how insect development has evolved over time.

Studies of the Habits and Development of Neocerata rhodophaga Coquillett [PDF]

open access: yes, 1904
About the year 1897, in the vicinity of Chicago, Illinois, certain varieties of roses grown under glass, notably the Meteor, were attacked by great numbers of minute cecidomyian larvae which destroyed the terminal leaf and blossom buds.

Low H2O2 and enhanced oxidative resistance in the diapause-destined pupa of silkworm, Antheraea mylitta (Lepidoptera:Saturniidae) suggest their possible involvement in dormancy and lifespan extension

open access: yes, 2018
BackgroundInsect diapause is associated with physiological dormancy, extension of life span and an altered developmental programme. Reactive oxygen species, oxidative damaged products and antioxidants are being increasingly linked to such processes in ...

Parasitoid wasp usurps its host to guard its pupa against hyperparasitoids and induces rapid behavioral changes in the parasitized host

open access: yesPLoS ONE, 2017
Some parasites have an ability to fabricate the behavior of their host and impel the host to guard parasites' offspring, which is popularly called as bodyguard manipulation.

Accessing the impact of harvest weights of Tenebrio molitor on amino acid digestibility and metabolizable energy in cecectomized laying hens

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The effects of harvest weights on composition, amino acid (AA) digestibility and metabolizable energy (MEN) of Tenebrio molitor (TM) were investigated using cecectomized laying hens. The partially defatted and dried TM variants comprised median individual frass‐free harvest weights of 60, 80, 100, and 120 mg of larvae, and a pupae ...

Bilateral Differentiation of Color and Morphology in the Larval and Pupal Stages of \u3ci\u3ePapilio Glaucus\u3c/i\u3e (Lepidoptera: Papilionidae) [PDF]

open access: yes, 2017
A sharply delineated, bilateral differentiation of color patterns and morphology were observed in a final (5th) instar larva of a subspecies backcross of a female Papilio glaucus glaucus with a hybrid male (P. g. glaucus x P. g. canadensis).

Comparative morphology of immature Trictenotoma formosana Kriesche, 1919 and systematic position of the Trictenotomidae (Coleoptera, Tenebrionoidea)

open access: yesEuropean Journal of Taxonomy, 2020
Detailed description and illustrations of immature Trictenotoma Gray, 1832 (Trictenotomidae Blanchard, 1845) are presented for the first time, based on larvae and pupae of T. formosana Kriesche, 1919.

Aspartate Decarboxylase is Required for a Normal Pupa Pigmentation Pattern in the Silkworm, Bombyx mori

open access: yesScientific Reports, 2015
The pigmentation pattern of Lepidoptera varies greatly in different development stages. To date, the effects of key genes in the melanin metabolism pathway on larval and adult body color are distinct, yet the effects on pupal pigmentation remains unclear.
