Survival and Food Detection by First-Instar \u3ci\u3eMelanoplus Femurrubrum\u3c/i\u3e (Orthoptera: Acrididae) [PDF]

open access: yes, 2017
Newly hatched Melanoplus femurrubrum (DeGeer) were evaluated for survival without food under various moisture, temperature, and light conditions. Although nymphs survived up to 113 h without food, they required food 48-W h after hatching to ensure ...

A Comparison of Three Approaches for Larval Instar Separation in Insects—A Case Study of Dendrolimus pini

open access: yesInsects, 2019
The number of larval instars is important from both theoretical and practical perspectives. Three previous studies based on head capsule widths (HCWs) have suggested that Dendrolimus pini larvae pass through seven instars, but the estimated HCW means ...

Gut microbiota is a potential factor in shaping phenotypic variation in larvae and adults of female bumble bees

open access: yesFrontiers in Microbiology, 2023
Host symbionts are often considered an essential part of the host phenotype, influencing host growth and development. Bumble bee is an ideal model for investigating the relationship between microbiota and phenotypes.

Transcriptional control of behaviour: engrailed knockout changes cockroach escape trajectories [PDF]

open access: yes, 2009
The cerci of the cockroach are covered with identified sensory hairs that detect air movements. The sensory neurons that innervate these hairs synapse with giant interneurons in the terminal ganglion that in turn synapse with interneurons and leg motor ...

Species and life stages of Odonata nymphs sampled with large drift nets in two Wisconsin rivers [PDF]

open access: yes, 2017
Because relatively few nymphs of Odonata are caught in most drift studies, they have been inconsistently reported and little is known about the species and life stages that are predisposed to drift.

Variation in honey bee gut microbial diversity affected by ontogenetic stage, age and geographic location [PDF]

open access: yes, 2015
Social honey bees, Apis mellifera, host a set of distinct microbiota, which is similar across the continents and various honey bee species. Some of these bacteria, such as lactobacilli, have been linked to immunity and defence against pathogens. Pathogen

Number of larval instars and sex-specific plasticity in the development of the small heath butterfly, Coenonympha pamphilus (Lepidoptera: Nymphalidae)

open access: yesEuropean Journal of Entomology, 2006
The number of larval moults, larval head capsule width and pupal weight were investigated in both direct-developing and diapausing individuals of a South-West European population of Coenonympha pamphilus.

Improved Monitoring of Grapholita molesta (Lepidoptera: Tortricidae) in Stone Fruit Orchards with a Pheromone-Kairomone Combination Lure

open access: yesInsects, 2020
Monitoring oriental fruit moth Grapholita molesta Busck (Lepidoptera: Tortricidae), populations based on counts in sex pheromone-baited traps within sex pheromone-treated orchards for mating disruption (MD) is challenging since male orientation to traps ...
