Differences in the phototaxis of pollen and nectar foraging honey bees are related to their octopamine brain titers

open access: yesFrontiers in Physiology, 2014
The biogenic amine octopamine is an important neuromodulator, neurohormone and neurotransmitter in insects. We here investigate the role of octopamine signaling in honey bee phototaxis.

THE FREEZING OF INSECTS [PDF]

open access: yesThe Canadian Entomologist, 1898
In the 22nd Report of the Entomological Society of Ontario, being that for 1891, there appeared a paper from my pen under the title “Can Insects Survive Freezing?”I have recently come across further records of observations upon this subject, and deem them of sufficient interest to be republished in the Canadian Entomologist.In looking over and ...

A Rhodnius prolixus Insulin Receptor and Its Conserved Intracellular Signaling Pathway and Regulation of Metabolism

open access: yesFrontiers in Endocrinology, 2018
The insulin signaling pathway is a modulator of metabolism in insects and can regulate functions associated with growth and development, as well as lipid and carbohydrate balance. We have previously reported the presence of an insulin-like peptide and an

Closely Related Tree Species Differentially Influence the Transfer of Carbon and Nitrogen from Leaf Litter Up the Aquatic Food Web [PDF]

open access: yes, 2014
Decomposing leaf litter in streams provides habitat and nutrition for aquatic insects. Despite large differences in the nutritional qualities of litter among different plant species, their effects on aquatic insects are often difficult to detect.

“Hearing of Insects” [PDF]

open access: yesNature, 1878
I AM able to confirm the accounts given by Mr. Simson in your last number as to the probability of the hearing of insects. When travelling on the River Magdalena, New Granada, in 1861, the mode of which is by a long boat, arched over with bamboo, on which the sailors (bogas) passing from one extremity to the other, propel it with long poles, hugging ...

Self‐Aligned Waveguide Array Integrated with Flat Microlenses for Environment‐Adaptive and High‐Resolution Compound Eye Vision

open access: yesAdvanced Optical Materials, EarlyView.
For an amphibious high‐resolution compound eye vision system, environment‐adaptive self‐aligned waveguides are integrated with high‐density flat microlenses. Fabrication, optical performance, and environmental adaptability are investigated, demonstrating stable focusing, efficient light collection, and enhanced spatial resolution.
