MicroRNA novel-miR-90-5p modulates larval molt development in Ostrinia furnacalis (Guenée) by targeting OfCYP18A1.

The hormone 20-hydroxyecdysone (20E) plays an important role in the physiological processes of insect growth, development, and ecdysis, whereas CYP18A1, a 20E hydroxylase, participates in 20E degradation and maintains its equilibrium state, which is an indispensable part of the 20E signaling pathway. MicroRNAs (miRNAs) are important post-transcriptional regulators of gene expression and mediate various biological processes. However, whether and how miRNAs regulate CYP18A1 remains unclear.

Identification and expression analysis of cathepsin B genes in (Hemiptera: Aphididae) and their response to environmental stresses.

Cathepsin B (CTSB) is a cysteine protease that is widely found in eukaryotes and plays a role in insect growth, development, digestion, metamorphosis, and immunity. In the present study, we examined the role of CTSB in response to environmental stresses in Sulzer (Hemiptera: Aphididae). Six genes, namely , and , were identified and cloned from .

Identification, expression analysis, and functional verification of three opsin genes related to the phototactic behaviour of Ostrinia furnacalis.

Ostrinia furnacalis is a disreputable herbivorous pest that poses a serious threat to corn crops. Phototaxis in nocturnal moths plays a crucial role in pest prediction and control. Insect opsins are the main component of insect visual system.

Integrated transcriptomic and proteomic analyses reveal the molecular mechanism underlying the thermotolerant response of Spodoptera frugiperda.

Spodoptera frugiperda (Lepidoptera: Noctuidae) is a highly destructive invasive pest with remarkable adaptability to extreme climatic conditions, posing a substantial global threat. Although the effects of temperature stress on the biological and ecological properties of S. frugiperda have been elucidated, the molecular mechanisms underlying its responses remain unclear.

Enzymatic activity and development of Frankliniella occidentalis (Thysanoptera: Thripidae) in response to exogenous calcium treatments of kidney bean plants.

Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) is an agricultural pest threatening various horticultural crops worldwide. Inducing plant resistance is an ecologically beneficial and potentially effective method for controlling F. occidentalis.

Expression and function of opsin genes associated with phototaxis in Zeugodacus cucurbitae Coquillett (Diptera: Tephritidae).

Background: Zeugodacus cucuribitae is a major agricultural pest that causes significant damage to varieties of plants. Vision plays a critical role in phototactic behavior of herbivorous insects. However, the effect of opsin on the phototactic behavior in Z.

Identification of Six Small Heat Shock Protein Genes in Ostrinia furnacalis (Lepidoptera: Pyralidae) and Analysis of Their Expression Patterns in Response to Environmental Stressors.

Ostrinia furnacalis (Guenée) is a major insect pest in maize production that is highly adaptable to the environment. Small heat shock proteins (sHsps) are a class of chaperone proteins that play an important role in insect responses to various environmental stresses. The present study aimed to clarify the responses of six O.

Molecular characterization of six heat shock protein 70 genes from Arma chinensis and their expression patterns in response to temperature stress.

Arma chinensis is an important predatory enemy of many agricultural and forest pests. Heat shock protein 70 (Hsp70) plays an essential role in insect adaptation to various stress factors. To explore the functions of Hsp70s in relation to thermal tolerance of A.

Induced heat shock protein 70 confers biological tolerance in UV-B stress-adapted Myzus persicae (Hemiptera).

As an environmental stress factor, ultraviolet-B (UV-B) radiation directly affects insect growth, development, and reproduction. Heat shock protein 70s kDa (Hsp70s) plays an important role in the environmental adaptation of insects. To determine the role of MpHsp70s in the UV-B tolerance of Myzus persicae (Sulzer), we identified the complete complementary DNA sequences of seven MpHsp70s.

Expression stability of candidate RT-qPCR housekeeping genes in Spodoptera frugiperda (Lepidoptera: Noctuidae).

Reverse-transcription quantitative polymerase chain reaction (RT-qPCR) is commonly used to quantify gene expression. For normalization, the expression of each gene is compared with a reference "housekeeping" gene that is stably expressed under relevant stress. Unfortunately, there have been no reports on the stability of such reference genes under various treatments of the Spodoptera frugiperda.

Identification of five small heat shock protein genes in Spodoptera frugiperda and expression analysis in response to different environmental stressors.

Spodoptera frugiperda (J. E. Smith) is a highly adaptable polyphagous migratory pest in tropical and subtropical regions.

Molecular Characterization and Expression of and in (Guenée) Under Different Environmental Stressors.

, an important pest of corn, has substantial detrimental effects on corn production. The mitogen-activated protein kinase (MAPK) signaling pathway plays a pivotal role in an insect's resistance to environmental stress. The expression levels of and have been well recorded in several insects under different environmental stressors, at different developmental stages, and in various tissue types; however, there is limited information on and in agricultural insects.

A proteomic analysis of Helicoverpa armigera adults after exposure to UV light irradiation.

Ultraviolet (UV) light (blacklight), which emits UV in the range of 320-400nm, has been used worldwide in light trapping of insect pests. To gain a better understanding of the response of Helicoverpa armigera adults to UV light irradiation, we carried out a comparative proteomic analysis. Three-day-old adults were exposed to UV light for 1h.

Ultraviolet light-induced oxidative stress: effects on antioxidant response of Helicoverpa armigera adults.

Ultraviolet (UV) light (blacklight), which emits UV in the range of 320-400 nm, has been used worldwide in light trapping of insect pests.
