“…Unlike vertebrate genomes, which are methylated globally up to 60-90% (of all CpG nucleotides in mammals) [80,81], methylation in insects is targeted to genes [82]. DNA methylation was empirically detected in many insect species [82][83][84], including a few Ortoptheran species such as Gryllotalpa fossor, Schistocerca gregaria, and Acheta domesticus [85][86][87]. In the genome of Acheta domesticus, the 'toolkit' for DNA methylation was detected.…”

The rising applicability of graphene oxide (GO) should be preceded by detailed tests confirming its safety and lack of toxicity. Sensitivity to GO of immature, or with different survival strategy, individuals has not been studied so far. Therefore, in the present research, we focused on the GO genotoxic effects, examining selected parameters of DNA damage (total DNA damage, double-strand breaks—DSB, 8-hydroxy-2′-deoxyguanosine-8-OHdG, abasic site—AP sites), DNA damage response parameters, and global methylation in the model organism Acheta domesticus. Special attention was paid to various life stages and lifespans, using wild (H), and selected for longevity (D) strains. DNA damage was significantly affected by stage and/or strain and GO exposure. Larvae and young imago were generally more sensitive than adults, revealing more severe DNA damage. Especially in the earlier life stages, the D strain reacted more intensely/inversely than the H strain. In contrast, DNA damage response parameters were not significantly related to stage and/or strain and GO exposure. Stage-dependent DNA damage, especially DSB and 8-OHdG, with the simultaneous lack or subtle activation of DNA damage response parameters, may result from the general life strategy of insects. Predominantly fast-living and fast-breeding organisms can minimize energy-demanding repair mechanisms.

“…When grasshoppers reproduce, they form a group, and when they die, they become decayed (Symmons & Cressman, 2001). The phases have distinct morphology (e.g., brain size, body size, and color), physiology (neuroendocrinological status), and behaviour (tendency to move with their crowd and reaction timing to moving objects) (Cabej, 2019). The phases of the locust are shown in Figure 1.…”

The desert locust [Schistocerca gregaria (Forskal)] (Orthoptera: Acrididae) is one of the world’s most dangerous and destructive migratory pests. It is a highly voracious and polyphagous insect. Its swarms can travel hundreds of kilometers per day and infest areas covering millions of square kilometers, resulting in substantial crop losses. We synthesize published research data and reports on the life cycle, behavior, phases, and damage of the desert locust, as well as its possible management practices, in this study. There are diffi-culties involved in estimating locust populations because locust swarms are highly mobile. Cultural control, baiting, dusting with insecticide, and spraying liquid insecticides (chemical or biological) using ultra-low volume (ULV) application are all options for control-ling locust swarms. Improved knowledge on pest biology, as well as more efficient monitoring and control strategies, are essential com-ponents of an effective management strategy.
