The serpentine sting bug preys on Lepidoptera larvae on the fern
Shanghai Chenshan Botanical Garden (Shanghai Chenshan Plant Science Research Center, Chinese Academy of Sciences) Pteridophyte Molecular Ecology and Functional Evolution Research Group has made new progress in the research of indirect defense of ferns, and discovered that there is a chemical relationship between the fern fern and the serpentine stink bug Communication mechanism
Insects Ferns and insects are two very ancient organisms.
In the process of evolution, plants have established various defense mechanisms against herbivorous insect feeding, such as the thickening of plant epidermis, the formation of epidermal spines, and the synthesis of toxic body fluids.
The assassin bug is a ubiquitous predatory insect of the Hemiptera Assassinidae, and the Pteridophyllum is a common fern in southern China in the Pteridophyte family
To this end, the researchers conducted field observations, analysis of plant volatile components, electrophysiological experiments, and behavioral experiments.
Experts said that this study not only confirmed the existence of the indirect defense mechanism of ferns, but also the first report of this mechanism
