Endemic grasshoppers (Orthoptera, Acridoidea) of the steppes of West Siberia and North-East Kazakhstan: how can we estimate their future?

open access: yesActa Biologica Sibirica
The distribution patterns of 3 rare acridid species, namely Asiotmethis jubatus (Uvarov, 1926) (Pamphagidae), Aeropedellus baliolus Mistshenko, 1951 and Mesasippus arenosus (Bey-Bienko, 1930), are described and compared. In the region, there are the type

Niche separation between two closely related species of the genus Lasiambia Anonym., 1937 (Diptera: Chloropidae) [PDF]

open access: yesКавказский энтомологический бюллетень, 2015
Habitat and types of feeding of larvae of the genus Lasiambia Anonym., 1937 are analyzed. Larvae of Lasiambia as opposite to most Chloropidae are not phytophagous and not associated with Poaceae grasses. Two groups of species are separated.

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

open access: yesOikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Antibacterial activity of lysozyme in the desert locust, Schistocerca gregaria (Orthoptera: Acrididae)

open access: yesEuropean Journal of Entomology, 2013
The ability of biocontrol agents to overcome the immune defense of pests is a crucial issue. This is the first study of lysozyme activity as an inducible humoral component of the defense of Schistocerca gregaria, which depends on the recognition of the ...

Representation of acoustic communication signals by insect auditory receptor neurons [PDF]

open access: yes, 2001
Despite their simple auditory systems, some insect species recognize certain temporal aspects of acoustic stimuli with an acuity equal to that of vertebrates; however, the underlying neural mechanisms and coding schemes are only partially understood.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.
