Preliminary checklist of the orthopteroid insects (Blattodea, Mantodea, Phasmatodea, Orthoptera) of Texas [PDF]

open access: yes, 2001
Texas has one of the most diverse orthopteroid assemblages of any state in the United States, reflecting the varied habitats found in the state. Three hundred and eighty-nine species and 78 subspecies of orthopteroid insects (Blattodea, Mantodea ...

Estado actual de la langosta Schistocerca cancellata paranensis (Burm.) en la República Argentina. Nuevos aportes a su bioecología

open access: yesActa Zoológica Lilloana, 2020
Hace algunas décadas, Schistocerca cancellata paranensis (Burm.) mostraba todas sus fases aparentemente bien definidas. Actualmente, no alcanza la fase gregaria, probablemente por el estricto control de sus poblaciones; según las condiciones imperantes,

Biophysics of object segmentation in a collision-detecting neuron

open access: yeseLife, 2018
Collision avoidance is critical for survival, including in humans, and many species possess visual neurons exquisitely sensitive to objects approaching on a collision course.

Regulatory mechanisms of reproduction in locusts and grasshoppers

open access: yesNew Plant Protection, EarlyView.
Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

A role of corazonin receptor in larval-pupal transition and pupariation in the oriental fruit fly Bactrocera dorsalis (Hendel) (Diptera: Tephritidae) [PDF]

open access: yes, 2017
Corazonin (Crz) is a neuropeptide hormone, but also a neuropeptide modulator that is internally released within the CNS, and it has a widespread distribution in insects with diverse physiological functions.

Evaluating the potential of RNA interference for control of striped cucumber beetle, Acalymma vittatum (Fabricius) (Coleoptera: Chrysomelidae)

open access: yesPest Management Science, EarlyView.
SCB has a robust RNAi response to injected dsRNA, but oral RNAi is less efficient. Nucleases do not appear to be responsible for the discrepancy, suggesting other factors are involved. Abstract BACKGROUND The striped cucumber beetle (SCB) is a serious pest of cucurbit crops, causing damage both by feeding on plants and by vectoring plant diseases ...

Identification and Characterization of the Corazonin Receptor and Possible Physiological Roles of the Corazonin-Signaling Pathway in Rhodnius prolixus. [PDF]

open access: yes, 2016
Neuropeptides control many physiological and endocrinological processes in animals, acting as neuroactive chemicals within the central and peripheral nervous systems.

DsiRNA‐mediated silencing of Ceratitis capitata transformer or transformer‐2 leads to masculinization of XX embryos and systemic gene silencing in ovaries

open access: yesInsect Science, EarlyView.
We carried out functional studies using Dicer‐substrate small interfering RNAs (DsiRNAs), targeting the sex determination genes Cctransformer (Cctra) and Cctransformer‐2 (Cctra‐2) in the Mediterranean fruit fly (Ceratitis capitata). Microinjection of DsiRNAs into XX embryos (0‐1 h old) rapidly triggered the expression of male‐specific Cctra isoforms ...

The synthesis of an analogue of the locust CRF-like diuretic peptide, and the biological activities of this and some C-terminal fragments. [PDF]

open access: yes, 2003
The synthesis is described of an analogue of the locust CRF-like diuretic peptide in which methionine in positions 1,3, and 13 is replaced by isosteric methyl-homoserine residues.

The phytochemical composition of Melia volkensii and its potential for insect pest management [PDF]

open access: yes, 2020
Due to potential health and environmental risks of synthetic pesticides, coupled with their non-selectivity and pest resistance, there has been increasing demand for safer and biodegradable alternatives for insect pest management.
