Human activities are accelerating rates of biological invasions and climate-driven range expansions globally, yet we understand little how genomic processes facilitate the invasion process. Although most literature has focused on underlying phenotypic correlates invasiveness, advances in technologies showing a strong link between variation success. Here, consider ability tools to (i) inform mechanistic understanding (ii) solve real-world issues predicting managing invasions. For both, examine current state field discuss genomics can be leveraged future. In addition, make recommendations pertinent broader research issues, such as data sovereignty, metadata standards, collaboration, science communication best practices that will require concerted efforts from global community.

Spodoptera frugiperda (J.E. Smith) (Noctuidae: Lepidoptera) is a notable insect pest that invades major cereal crops, causing significant damage and loss. Resistances of 2nd instar larvae two Egyptian field populations S. frugiperda, collected from the Fayoum Giza governments, were measured against eight insecticides, including traditional insecticides (profenofos cypermethrin), bio-insecticides (emamectin benzoate, spinosad, Bacillus thuringiensis), growth regulators (IGRs) (lufenuron, diflubenzuron, methoxyfenozide). In addition, synergistic effects three synergists (Piperonyl butoxide (PBO), diethyl maleate (DEM), triphenyl phosphate (TPP) assessed, activities detoxification enzymes (acetylcholine esterase (AChE), cytochrome P-450 (CYP-450), carboxylesterase (CarE), glutathione-s-transferase (GST) also determined. Resistance surveillance revealed population showed moderate resistance to cypermethrin (RR = 5.75-fold), followed by spinosad 2.62-fold), lufenuron (2.01-fold). On other hand, exhibited only 3.65-fold). Our results emamectin benzoate was most effective insecticide, with an LC50 value 0.003 mg/L for 0.001 population, compared susceptible strain (0.005 mg/L). Among biological thuringiensis least toxic insecticide all tested strains. Synergism assays indicated DEM TPP had effect on (SR 8.00-fold both), PBO 5.71-fold) alone. The assay GST activity significantly (p < 0.05) increased in strains strain. However, no changes observed among CYP-450, CarE, or AChE. findings this study provide substantial insights into tracking managing development Egypt.

Light traps are a useful method for monitoring and controlling the important migratory pest, fall armyworm, Spodoptera frugiperda. Studies have shown that S. frugiperda is sensitive to blue, green, or ultraviolet (UV) light, but conclusions inconsistent. Furthermore, conventional black light less effective trapping To improve efficiency of this it crucial determine specific wavelength which measure its flight capability under wavelength. This study investigated effects on phototaxis performance The results showed blue was most among three different LED lights unaffected by gender. varied significantly in conditions, especially speed. fastest speed observed whereas slowest UV compared dark conditions. During 12 h period, declined more rapidly slowly UV, remained stable Meanwhile, proportion fast-flying individuals highest higher than light. Therefore, use equipped with can These also provide insights further research pollution insects.

The fall armyworm (FAW), Spodoptera frugiperda, is a worldwide agricultural pest that invaded China in 2018, and has developed resistance to multiple insecticides. evolution of insecticide facilitated by mutations target genes responsible for conferring resistance. In this study, amplicon sequencing analyzed 21 sites six genes. addition known mutations, unknown variants were also found, including novel variants: F290C (ace-1 gene, 0.1% frequency), I1040T/V (CHSA A309T (GluCl I4790T/V (RyR frequency). Additionally, molecular docking was employed investigate the impact aforementioned new on binding proteins. analyses indicated abilities reduced, similar reported, implying these may confer transitional This study provide foundation understanding functions evolutionary processes drive emergence invasive species.

Insect glutathione S-transferases (GSTs) serve critical roles in insecticides and other forms of xenobiotic chemical detoxification. The fall armyworm, Spodoptera frugiperda (J. E. Smith), is a major agricultural pest several countries, especially Egypt. This the first study to identify characterize GST genes S. under insecticidal stress. present work evaluated toxicity emamectin benzoate (EBZ) chlorantraniliprole (CHP) against third-instar larvae using leaf disk method. LC50 values EBZ CHP were 0.029 1.250 mg/L after 24 h exposure. Moreover, we identified 31 genes, including 28 cytosolic 3 microsomal SfGSTs from transcriptome analysis genome data frugiperda. Depending on phylogenetic analysis, sfGSTs divided into six classes (delta, epsilon, omega, sigma, theta, microsomal). Furthermore, investigated mRNA levels qRT-PCR stress Interestingly, SfGSTe10 SfGSTe13 stood out with highest expression treatments. Finally, molecular docking model was constructed between most upregulated (SfGSTe10 SfGSTe13) least (SfGSTs1 SfGSTe2) larvae. showed have high binding affinity SfGSTe10, energy -24.41 -26.72 kcal/mol, respectively, sfGSTe13, -26.85 -26.78 respectively. Our findings are important for understanding role GSTs regarding detoxification processes CHP.

Abstract Continuous and long‐term use of traditional new pesticides can result in cross‐resistance among pest populations different fields. Study on the mechanism related genes will help resistance management field control. In this study, pesticide‐resistance Spodoptera frugiperda (FAW) was studied with 3 locations South China. Field FAW were highly resistant to insecticides, chlorpyrifos (organophosphate) deltamethrin (pyrethroid), had higher levels cytochrome P450 activity than a non‐resistant laboratory strain. Inhibition by piperonyl butoxide significantly increased sensitivity chlorpyrifos, chlorantraniliprole (amide), type insecticide, suggesting that detoxification is critical factor for insecticide populations. Transcriptomic analysis indicated 18 upregulated collected regions 2 consecutive years, CYP321A8 , most one. Knockdown messenger RNA interference resulted an tested insecticides FAW.

ABSTRACT Cyclaniliprole, a type of the third‐generation anthranilic diamide insecticide, was mainly used for management various pests. Myzus persicae (Hemiptera: Aphididae), known as peach‐potato aphid, is an economically essential pest with worldwide distribution. However, risk assessment cyclaniliprole in M. unclear. The showed 2.56‐fold resistance to after 26 generation selection comparison initial susceptible population. cross‐resistance experiment revealed that low imidacloprid (4.2‐fold) cyclaniliprole‐selected strain observed when comparing Realized heritability ( h 2 ) 0.0362. When mean slope = 2.217 and 0.0362, then 31–69 generations would be required increase LC 50 s ten times at 90%–50% intensity. fecundity (the number offspring per female) had no significant difference mRNA expression target gene ryanodine receptor significantly enhanced strain. absence fitness costs, minimal risk, very levels provide strong support designing effective strategies against .
