Symbiont‐Induced HSP83 Establishes Two‐Tiered Control of Antifungal Immunity in an Invasive Beetle–Fungus Complex

open access: yesAdvanced Science, EarlyView.
In an invasive beetle–fungus complex, the mutualist Leptographium procerum induces host HSP83 and modulates Toll‐dependent antifungal immunity. HSP83 mediates two‐tiered control by associating with selected fungal recognition receptors and restraining Dorsal‐driven antimicrobial peptide transcription.

Ecological and physiological aspects of aestivation-diapause in the larvae of two Pyralid stalk borers of maize in Kenya [PDF]

open access: yes, 1978
Stalk borers are highly destructive to a large number of important graminaceous crops all over the world. Some examples of economically important stalk borers and a general description of their life-cycle are mentioned in chapter 1.

Guidelines for High‐Throughput Screening for Natural Products With Anti‐Aging Activity Based on Drosophila Intestinal Homeostasis

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
ABSTRACT Aging represents a critical risk factor for chronic diseases, driving an urgent demand for interventions promoting healthy longevity. This study establishes standardized guidelines for high‐throughput screening (HTS) of anti‐aging natural products using Drosophila melanogaster, leveraging its intestinal homeostasis as a biomarker.

Influence of baculovirus AdorGV on the mortality of larvae and pupae of summer fruit tortrix Adoxophyes orana in laboratory conditions

open access: yesPlant Protection Science, 2007
The mortality of larvae and pupae of Adoxophyes orana was examined by keeping larvae of each larval instar (L1-L5) on an artificial diet in laboratory conditions. Larvae were infected by using an artificial diet containing AdorGV-based CAPEX® 2.

ULTRASTRUCTURE OF MID-GUT OF THE THIRD LARVAL INSTAR OF GASTEROPHILUS INTESTINALIS (DIPTERA: GASTEROPHILIDAE) [PDF]

open access: yesVeterinary Medical Journal - Giza, 2004
Mid-gut of both early and late third larval instar of Gasterophilus intestinalis was investigated by electronmicroscop. Electronmicrographs of early and late larval instars illustrate difference in the structures of apical border, the microvilli, basal ...

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Dusky-like Is Critical for Morphogenesis of the Cellular Protuberances and Formation of the Cuticle in Henosepilachna vigintioctopunctata

open access: yesBiology, 2023
Dusky-like (Dyl) is a transmembrane protein containing a zona pellucida domain. Its physiological roles during metamorphosis have been well explored in Drosophila melanogaster and have also been documented in Tribolium castaneum.

Hypertrehalosaemic and hyperlipaemic responses to adipokinetic hormone in fifth larval instar locusts, Locusta migratoria [PDF]

open access: yes, 1984
In fifth instar larvae of Locusta migratoria the haemolymph lipid concentration is elevated after injection of adipokinetic hormone (AKH). This hyperlipaemic response in larvae remains substantially lower than in adults; over 75% of the mobilized lipid ...
