Abstract In Brazil, the common earwig Doru luteipes (Scudder) (Dermaptera: Forficulidae) is considered an important biocontrol agent for maize crop, consuming fall armyworm Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae) eggs and caterpillars from 1st to 3rd instar. Despite this, several aspects of interaction between these species have not yet been studied.

Predators are dependent on the capture of prey to meet their energetic and nutritive requirements, imposing a regime predation risk. Consequently, experience both consumptive non-consumptive effects. Non-consumptive effects may manifest through altered growth ontogenetic trajectories species, dynamic modulated by olfactory or other sensory cues from predators. Bactrocera dorsalis Hendel represents great invasive threat global horticulture. While earlier research has primarily centered interactions between B. its natural enemies, potential consequences development have been overlooked. In this study, we investigated impact risk effects, induced visual exposure predatory mantis Hierodula patellifera Serville associated odor, life history traits dorsalis. Female demonstrated reduced time in presence isolated H. yet evidenced significantly increased fecundity. Conversely, males displayed no significant change time. Additionally, neither female nor male body weight at death was influenced predators predator odor. These results indicated adaptive developmental strategies when faced with risks highlight important role which lay groundwork for improving biological control efforts innovative approaches within pest control.

Predation reduces the population density of prey, affecting its fitness and dynamics. Few studies have connected trait changes with consequences in prey molecular basis metabolic mechanisms such bat-insect systems. This study focuses on responses Helicoverpa armigera to different predation risks, focusing echolocating bats their calls. Substantial modifications were observed nocturnal diurnal activities H. under risk, enhanced evasion behaviors. Accelerated development decreased risks. Transcriptomic metabolomic analyses indicated that exposure induced upregulation amino acid metabolism- antioxidant pathway-related genes, reflecting shifts resource utilization response oxidative stress. Exposure bat risks activity DNA damage repair pathways suppressed energy metabolism, contributing decreases. The current results underscore complex adaptive strategies species evolve enhancing our understanding predator–prey dynamic offering valuable insights for innovative ecologically informed pest management strategies. shows increased evasion, accelerated development, Molecular reveal metabolism stress linked these changes.

Abstract Animals use predation encounters or risk experiences to influence their future antipredator responses. Such carryover effects of can benefit them by enhancing behaviour and thereby decreasing mortality through predation. Despite these fitness benefits, behavioural carryovers past may not be a common phenomenon in complex life cycles. Complex cycles pose unique evolutionary physiological challenge since every stage is distinct morphology, physiology, function. Each cycle expected evolve its independent response based on the real-time threat level manage trade-offs accordingly. Along with challenge, barriers hamper carryovers, especially holometabolous insects, where we observe extensive tissue remodelling developmental compartmentalisation. We investigated mosquito model system, Aedes aegypti . asked whether during carries over subsequent stage, influencing behaviour, if next responds according environment. has four major stages– egg, larva, pupa, adult. examined effect predation-risk experience across larval pupal stages.

An increasing body of research has underscored the significant impact non-consumptive effects on dynamics prey pests, encompassing growth, development, reproduction, and metabolism across various vertebrate invertebrate taxa, rivaling influence consumption effects. In our investigation, we delved into exerted by natural predatory enemy Harmonia axyridis reproductive capacity Spodoptera frugiperda adults. Our findings revealed a substantial decrease in ability S. adults when exposed to H. axyridis. Concurrently, observed an elevation hydrogen peroxide (H2O2) content activities antioxidant enzymes such as superoxide dismutases (SODs), catalases (CATs), peroxidases (PODs). Furthermore, notable alterations were detected energy metabolism, characterized heightened triglyceride levels diminished glycogen trehalose concentrations. These outcomes adaptive response pest aimed at mitigating adverse augmenting enzyme activity counteract oxidative stress minimize cellular damage. Nonetheless, this defensive mechanism entails expenditure resources, resulting shifts utilization. Elevated reduced concentrations diminish available resources for processes, egg laying, ultimately culminating decreased fecundity. This study contributes novel insights insects, while also furnishing valuable mechanisms underlying insect responses.

The effects of predatory natural enemies on their prey or hosts involve both consumption and non-consumptive effects. This study investigated the predator, Harmonia axyridis (Coleoptera: Coccinellidae) 1st, 2nd 3rd instar larvae Spodoptera frugiperda. We exposed different instars to predator assessed various parameters using a combination biological biochemical methods. Exposure significantly affected growth development S. frugiperda caterpillars. Firstly, developmental duration in 1st–3rd pupal stage were notably prolonged. Moreover, we observed significant mass, abnormality rate emergence rate. These gradually weakened with an increase larval predator. Antioxidant enzyme activities including catalase (CAT) peroxidase (POD) superoxide dismutase (SOD) activity increased significantly. Additionally, organismal triglyceride, trehalose glycogen content altered by effects, while protein showed no change. antioxidant enzymes response potential predators mitigate oxidative stress reduce cellular tissue damage. resources redistribution towards survival may inhibit species further exacerbate these findings highlight importance considering pest-management strategies optimize control measures agricultural systems.
