Evaluation of different induced molting methods in Callinectes ornatus (Crustacea, Decapoda, Portunidae) as a tool for the commercial production of soft-shell crabs [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2021
We investigated the effects of eyestalk ablation and cheliped autotomy in inducing molting in Callinectes ornatus. The specimens in intermolt stage were divided into two size classes: 1 (30-50 mm) and 2 (51-70 mm) and were further divided into four ...

Evidence for a conserved CCAP-signaling pathway controlling ecdysis in a hemimetabolous insect, Rhodnius prolixus

open access: yesFrontiers in Neuroscience, 2013
A vital feature in the success of Ecdysozoa is their ability to shed their exoskeleton (a process called ecdysis) such that they can grow or change their morphology.

Drosophila Zic family member odd-paired is needed for adult post-ecdysis maturation [PDF]

open access: yesOpen Biology, 2019
Specific neuropeptides regulate in arthropods the shedding of the old cuticle (ecdysis) followed by maturation of the new cuticle. In Drosophila melanogaster, the last ecdysis occurs at eclosion from the pupal case, with a post-eclosion behavioural ...

Regenerative agriculture: merging farming and natural resource conservation profitably [PDF]

open access: yesPeerJ, 2018
Most cropland in the United States is characterized by large monocultures, whose productivity is maintained through a strong reliance on costly tillage, external fertilizers, and pesticides (Schipanski et al., 2016).

A Life History Study of Caecilius Aurantiacus (Hagen) (Psocoptera: Caeciliidae) [PDF]

open access: yes, 2017
Caecilius aurantiacus is a common, widely distributed psocid in well established forested areas of North America. Published information on this species is fragmentary and limited primarily to taxonomy.

Arrhythmic adult ecdysis but rhythmic emergence from the host chorion in Trichogramma embryophagum (Hymenoptera: Trichogrammatidae)

open access: yesEuropean Journal of Entomology, 2008
In many insect species with a pupa covered by various "shells" (puparium, host remains, etc.) pupal-adult ecdysis and emergence to the open air represent two discrete steps.

First Record of \u3ci\u3eHippodamia variegata\u3c/i\u3e (Coleoptera: Coccinellidae) in Illinois, U.S.A., and Relation to Its Other Midwestern Collection Records [PDF]

open access: yes, 2017
Hippodamia variegata (Goeze) (Coleoptera: Coccinellidae) is an Afro-Eurasian lady beetle first discovered in North America near Montreal, Canada, in 1984. Subsequent records of H. variegata have occurred over a gradually expanding area radiating from the

Transcriptomic analysis of crustacean neuropeptide signaling during the moult cycle in the green shore crab, Carcinus maenas

open access: yesBMC Genomics, 2018
Background Ecdysis is an innate behaviour programme by which all arthropods moult their exoskeletons. The complex suite of interacting neuropeptides that orchestrate ecdysis is well studied in insects, but details of the crustacean ecdysis cassette are ...

Notes on the Biology and Parasitoids of the Sweet Fern Underwing (Lepidoptera: Noctuidae) in Michigan [PDF]

open access: yes, 2017
(excerpt) The sweet fern underwing, Catocala antinympha (Hubner), sometimes called the wayward nymph (Holland, 1968), is one of several lepidopterous defoliators of sweet fern, Comptonia peregrina (L.) Coult.

Stereotyped responses of Drosophila peptidergic neuronal ensemble depend on downstream neuromodulators

open access: yeseLife, 2016
Neuropeptides play a key role in the regulation of behaviors and physiological responses including alertness, social recognition, and hunger, yet, their mechanism of action is poorly understood.
