Abstract Due to the absence of acquired immunity, insects primarily rely on their innate immune system resist pathogenic microorganisms and parasitoids in natural habitats. This can be classified into cellular immunity humoral immunity. Cellular is mediated by hemocytes, which perform phagocytosis, aggregation, encapsulation fight against invaders, whereas activates signaling pathways induces generation effectors. Existing studies have revealed that hemipteran aphids lack some crucial genes compared other insect species, indicating different mechanisms aphids. The current review summarizes adverse impacts aphids, introduces systems insects, analyzes differences between species. Furthermore, our also discussed existing prospects challenges aphid research, proposed potential application green pest management.

Globally, biotic factors like insect pests and diseases as well abiotic fire, windstorms, droughts influence the global forest ecosystem. Wood-boring (WBPs) pose a considerable threat to ecosystems worldwide owing their capacity of remaining unnoticed during early stages, resulting in vast pervasive infestations later eventually significant tree death. Therefore, it is crucial promptly effectively treat early-stage WBPs by timely detection. The prompt detection requires use advanced effective methods, such remote sensing. This paper provides an overview many uses several sensing devices, platforms, algorithms context monitoring infestations. Modern lightweight sensors light ranging (LiDAR), hyperspectral imagers, thermal cameras, radio (Radar) combined with unmanned aerial vehicles (UAVs) versatile capabilities offer comprehensive method for gathering data. purpose this study examine current capabilities, limits, potential future advancements accurately identifying WBPs.

Hemolymph enables communication between organs in insects and ensures necessary coordination homeostasis. Its composition can provide important information about the physiological state of an insect have diagnostic significance, which might be particularly case harmful subjected to biological control. Galleria mellonella Linnaeus 1758 (Lepidoptera: Pyralidae) is a global pest honey bee colonies. The hemolymph its larvae was examined after infection with soil fungus Conidiobolus coronatus (Constantin) Batko 1964 (Entomophthorales). It found that one hour contact fungus, volume increased while total protein content decreased. In high pathogen load, just before death, decreased nearly initial levels, synthesis (incorporation 35S-labeled methionine) increased. polypeptide profile (SDS-PAGE followed by autoradiography) infected significantly different from healthy larvae. Hemocytes did not surround fungal hyphae, although they encapsulated small foreign bodies (phase contrast microscopy). Infection had negative effect on hemocytes, causing oenocyte spherulocyte deformation, granulocyte degranulation, plasmatocyte vacuolization, hemocyte disintegration.

ABSTRACT Over millions of years interactions, plants have developed complex defense mechanisms to counteract diverse insect herbivory strategies. These defenses encompass morphological, biochemical, and molecular adaptations that mitigate the impacts herbivore attacks. Physical barriers, such as spines, trichomes, cuticle layers, deter herbivores, while biochemical include production secondary metabolites volatile organic compounds (VOCs). The initial step in plant's involves sensing mechanical damage chemical cues, including oral secretions herbivore‐induced VOCs. This triggers changes plasma membrane potential driven by ion fluxes across plant cell membranes, activating signal transduction pathways. Key hormonal mediators, jasmonic acid, salicylic ethylene, orchestrate downstream responses, VOC release biosynthesis. review provides a comprehensive analysis responses herbivory, emphasizing early late mechanisms, encompassing physical cascades, synthesis, phytohormone signaling, epigenetic regulation.
