“…GST and β-glucosidase activity increased in A. pomi after 24 h of the experiment ( Figure 2 A,B). The GST induction suggested that the increase in temperature caused the accumulation of toxic lipid peroxidation products and GST was involved in their inactivation [ 11 , 36 ], which was observed in A. pomi from 48 h. An increase in GST activity was also observed as a result of a change in the host plant in R. padi and S. avenae cereal aphids [ 18 ], and C. tujafilina [ 37 ], which were treated with secondary plant metabolites [ 18 ]. The increase in GST activity is an essential indicator of the adaptation of insects to changes in xenobiotics, including phenols, present in plants [ 17 ].…”

“…The increase in GST activity is an essential indicator of the adaptation of insects to changes in xenobiotics, including phenols, present in plants [ 17 ]. Changes in β-glucosidase and GST activity were noted in migration from primary to secondary host of winged R. padi females [ 38 ] and after the change of host plant in C. tujafilina [ 37 ]. β-glucosidase activity is strongly associated with the chemical composition of the host plant.…”

“…An increase in temperature in the range from 10 to 35 °C caused an increase in β-glucosidase activity in Eurygaster maura [ 39 ], while an increase in temperature above 30 °C in A. gifuensis caused an increase in GST activity [ 35 ]. β-glucosidase is associated with carbohydrate metabolism, the activity strongly linked with the composition of the sap in host plant, particularly sucrose concentration [ 37 ]. β-glucosidase hydrolyzes o-glycosyl bonds carbohydrates such as sucrose [ 39 ].…”

Climate change, and in particular the increase in temperature we are currently observing, can affect herbivorous insects. Aphids, as poikilothermic organisms, are directly exposed to temperature increases that influence their metabolism. Heat stress causes disturbances between the generations and the neutralization of reactive oxygen species (ROS). The aim of this work is focused on explaining how the aphid, using the example of Aphis pomi, responds to abiotic stress caused by temperature increase. The experiment was carried out under controlled conditions at three temperatures: 20, 25, and 28 °C. In the first stage, changes in the activity of enzymatic markers (superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST), β-glucosidase, polyphenol oxidase (PPO), and peroxidase (POD)) were determined in aphid tissues, at each temperature. In the second stage, microcalorimetry monitored changes in heat emitted by aphids, at each temperature. Our results showed that A. pomi defense responses varied depending on temperature and were highest at 28 °C. The flexible activity of enzymes and increase in the metabolic rate played the role of adaptive mechanisms and ran more effectively at higher temperatures. The A. pomi thus protected itself against ROS excessive induction and the aphids were able to respond quickly to environmental stress.

“…Numerous abiotic factors, such as temperature above the thermal optimum [ 24 ], treatment with pesticides or adverse response of the host plant [ 25 , 26 ] may lead to imbalance between the production of reactive oxygen species (ROS) and antioxidant processes in both plants and aphids [ 27 , 28 ]. The sudden increase in ROS levels is toxic to cells and leads to the destruction of proteins, lipids, and DNA [ 29 , 30 ].…”

The hemp aphid Phorodon cannabis Passerini is a well- known (Asia, Europe) or newly emerging (North America) insect. It is a monophagous insect pest causing considerable damage in field and glasshouse cultivations. The aim of this work was to study the effects of meteorological (temperature) and agronomical (herbicide) factors on the biology of the hemp aphid. In one experiment, hemp plants were kept at constant temperatures ranging from 20 to 30 °C, and aphid survival and fecundity were measured. In a related experiment conducted at 20 °C, plants were treated with field-appropriate rates of a selective graminicide containing quizalofop-P-tefuryl (40 gL−1, 4.38%, HRAC group 1), commonly used to control weeds in hemp, and aphid enzyme activity was measured in addition to population parameters. We found that hemp aphids could live, feed and reproduce within the whole studied range of temperatures, demonstrating its great evolutionary plasticity. However, the optimal temperature for development was 25 °C, at which the insect lived and reproduced for 25 and 15 days, respectively, with an average fecundity of 7.5 nymphs per reproduction day. The herbicide treatment increased the activity of superoxide dismutase (SOD), catalase (CAT), β-glucosidase, S-glutathione transferase (GST), oxidoreductive peroxidase (POD), and polyphenol oxidase (PPO) in the aphids, but only on certain days after treatment, which indicates a mild stress in aphid tissues, related to a higher reproduction and changed feeding behavior; aphids moved from the actively growing tips compared to untreated plants. The results of these experiments are discussed in terms of the impact on the future management of this pest.
