Phase-dependent morphometric traits of the albino strain of Schistocerca gregaria (Orthoptera: Acrididae) [PDF]

open access: yesJournal of Orthoptera Research, 2017
Sugahara et al. (2017) reported that unlike the wild type, the albino strain of Schistocerca gregaria does not show phase-dependent shift in the morphometric ratio of F/C (= length of the hind femur/maximum width of the head [caput]). In contrast, my old,

Preliminary larvicidal effect of seed oil from Cleome arabica L. on fifth instar larvae of Schistocerca gregaria (Orthoptera: Acrididae)

open access: yesActa Zoológica Lilloana, 2022
In this present study, the toxicity of Cleome arabica L. (Capparidaceae) seed oils was tested on L5 larvae of Schistocerca gregaria, Forsk. (Orthoptera-Acrididae). The forced administration of 60 ?L/individual of this vegetable oil leads to the death of

Exploring the relationship between tychoparthenogenesis and inbreeding depression in the Desert Locust, Schistocerca gregaria [PDF]

open access: yes, 2017
Tychoparthenogenesis, a form of asexual reproduction in which a small proportion of unfertilized eggs can hatch spontaneously, could be an intermediate evolutionary link in the transition from sexual to parthenogenetic reproduction.

Cellulolytic Bacillus species isolated from the gut of the desert locust Schistocerca gregaria

open access: yesScientific African, 2021
The ability of many insects to thrive on wood, foliage, and detritus has stimulated an interest on the potential use of gut microbial flora of such species as a bioresource for industrial conversion of cheap cellulosic material into bioproducts.

Band movement and thermoregulation in Schistocerca cancellata

open access: yesJournal of Insect Physiology, 2022
At high density, juvenile locusts create marching hopper bands. Understanding the roles of temperature and vegetation on the movement of these bands shall allow to better forecast and control them. Following a hopper band in North Argentina in November 2019, we explored the thermoregulation behaviours of the South American locust, Schistocerca ...

The head direction circuit of two insect species

open access: yeseLife, 2020
Recent studies of the Central Complex in the brain of the fruit fly have identified neurons with activity that tracks the animal’s heading direction. These neurons are part of a neuronal circuit with dynamics resembling those of a ring attractor.
