Distribution of First Instar Gypsy Moths (Lepidoptera: Lymantriidae) Among Saplings of Four Tree Species Common in the Great Lakes Region [PDF]

open access: yes, 2018
We examined the inter-tree distribution of first instar gypsy moth larvae under natural dispersal conditions in the field in Michigan in 1991. The study focused on saplings of northern red oak (Quercus rubra), white oak (Q. alba), red maple (Acer rubrum),

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.

LARVAL SPECIFIC CHARACTERS AND INSTARS OF ENGLISH BOMBIDAE

open access: yesProceedings of the Royal Entomological Society of London. Series A, General Entomology, 1949
FOURTH instar larval characters of American BOMBIDAE (BREMIDAE) were described by Ritcher (1933) for nine species of Bombus (Bremus) and one species of Psithyrus. These two genera were separated on the shape of the mandibles. An attempt was made to separate the species of Bombus (Bremus) on the characters of the mesothoracical spiracles and the pleural

Intracellular Aβ42 Sequestration by a Serine Protease Mitigates Neurotoxicity in a Drosophila Alzheimer's Disease Model

open access: yesAdvanced Science, EarlyView.
Emerging evidence suggests that intraneuronal Aβ accumulation represents an early pathogenic event in Alzheimer's disease (AD). Using Drosophila AD model, this study shows that a nonsecreted serine protease Yip7 physically interacts with Aβ. This causes intraneuronal Aβ accumulation but surprisingly reduces the associated neurotoxicity, arguing that ...

Microbial Gut Diversity of Africanized and European Honey Bee Larval Instars

open access: yesPLoS ONE, 2013
The first step in understanding gut microbial ecology is determining the presence and potential niche breadth of associated microbes. While the core gut bacteria of adult honey bees is becoming increasingly apparent, there is very little and inconsistent information concerning symbiotic bacterial communities in honey bee larvae.
