The Capability of Some Butterflies as Carriers of Common Milkweed Pollen [PDF]

open access: yes, 2017
The common milkweed, Asclepias syriaca L., is remarkably adapted for cross pollination by insects. Its pollen sacs (pollinia) are often found attached to the appendages of bees, wasps, butterflies, and other insects that visit milkweed for its nectar ...

Studies on neotropical Phasmatodea XXI: Sigaruphasma, a new genus of Hesperophasmatini Bradley & Galil, 1977, from Hispaniola with the descriptions of two new species (Phasmatodea: Cladomorphinae)

open access: yesNovitates Caribaea, 2020
The new Hesperophasmatini–genus Sigaruphasma gen. nov. from Hispaniola is described and illustrated. It is remarkable for violating several of the previously stated diagnostic features of the tribe Hesperophasmatini Bradley and Galil, 1977.

Cytochrome P450 Genes Expressed in Phasmatodea Midguts

open access: yesInsects, 2022
Cytochrome P450s (CYPs) are xenobiotic detoxification genes found in most eukaryotes, and linked in insects to the tolerance of plant secondary chemicals and insecticide resistance. The number and diversity of CYP clans, families, and subfamilies that an

Biosynthesis of Quinoline by a Stick Insect

open access: yesJournal of Natural Products, 2021
The Peruvian stick insect Oreophoetes peruana is the only known animal source for unsubstituted quinoline in nature. When disturbed, these insects discharge a defensive secretion containing quinoline. Analysis of samples obtained from l-[2',4',5',6,'7'-2H5]tryptophan-fed stick insects demonstrated that the insects convert it to [5,6,7,8-2H4]quinoline ...

Force dynamics and synergist muscle activation in stick insects: the effects of using joint torques as mechanical stimuli.

open access: yesJ Neurophysiol, 2018
Many sensory systems are tuned to specific parameters of behaviors and have effects that are task-specific. We have studied how force feedback contributes to activation of synergist muscles in serially homologous legs of stick insects.

The response of neotropical dragonflies (Insecta: Odonata) to local and regional abiotic factors in small streams of the Amazon [PDF]

open access: yes, 2019
Since the relative role of local and regional abiotic factors on the Odonata diversity in rainforest streams is still poorly understood, we evaluated the effects of these factors on adult Odonata (Insecta) from preserved and altered streams in the ...

DNA methylation differences between stick insect ecotypes

open access: yesMolecular Ecology, 2023
AbstractEpigenetic mechanisms, such as DNA methylation, can influence gene regulation and affect phenotypic variation, raising the possibility that they contribute to ecological adaptation. Beginning to address this issue requires high‐resolution sequencing studies of natural populations to pinpoint epigenetic regions of potential ecological and ...

A kinematic model of stick‐insect walking [PDF]

open access: yesPhysiological Reports, 2019
Animal, and insect walking (locomotion) in particular, have attracted much attention from scientists over many years up to now. The investigations included behavioral, electrophysiological experiments, as well as modeling studies. Despite the large amount of material collected, there are left many unanswered questions as to how walking and related ...

Eggs of Stick Insects [PDF]

open access: yesNature, 1938
JUDGING by a recent correspondence in NATURE1, a number of readers are interested in rearing the common stick insect (Carausus). In any quantitative work on Carausus, it is a tedious operation to secure the eggs which are deposited among the debris of the breeding cage where, on account of their 'protective' devices, they may easily escape observation.
