Density-dependent phenotypic plasticity in the South American Locust, Schistocerca cancellata (Orthoptera: Acrididae)
(Entomological Society of America, 2019-09)
Historically, the South American locust, Schistocerca cancellata (Serville, 1838), has been considered the most serious agricultural pest in Argentina. An outbreak of a magnitude not recorded since 1954 started in 2015 ...
Infectivity of Paranosema locustae (Microsporidia) against gregarious-phase South American locust (Orthoptera) when treated en masse
(Academic Press Inc Elsevier Science, 2020-11)
En masse inoculations with Paranosema locustae, an intracellular parasite of adipose tissue of grasshoppers and locusts and the only microsporidium registered as a biocontrol agent, were conducted against crowded fourth-instar ...
Two identified looming detectors in the locust: Ubiquitous lateral connections among their inputs contribute to selective responses to looming objects
(Nature Publishing Group, 2016-10)
In locusts, two lobula giant movement detector neurons (LGMDs) act as looming object detectors. Their reproducible responses to looming and their ethological significance makes them models for single neuron computation. ...
Morphometric differentiation in a field population of Dichroplus maculipennis (Orthoptera: Acrididae: Melanoplinae) under outbreak and non-outbreak situations
(Orthopterists' Society, 2015-12)
Dichroplus maculipennisis one of the most damaging grasshopper species of Argentina. Individuals of this species at high density are historically known to show aggregation behavior and dispersal flights, attributes that ...
