Semiochemicals are defined as informative molecules mainly used in plant-insect or insectinsect interactions alternative complementary components to insecticide approaches different integrated pest management strategies.They manipulate insect behaviour by affecting the survival and/or reproduction of pests for controlling their infestations on crops.The present review provides a basic summary utilization semiochemicals pests.Two main topics were explored this study.The first topic focuses description and types (pheromones allelochemicals).Pheromones represent an intraspecific communication amidst members same species.Allelochemicals, produced individuals one species, modify behavior species (i.e. interspecific effect).Allelochemicals include such as: allomones, kairomones, synomones, antimones apneumones.The second application IPM programs.Different included programs various ways monitoring, mass trapping, attract-and-kill, push-pull, disruption strategies.Pheromones promising can be singly integration with other control strategies monitoring agricultural systems.For example, sex pheromones have been applied attract-and-kill tactics programs.

Factors affecting catches of bark beetles and woodboring beetles in traps

Journal of Pest Science, Journal Year: 2024, Volume and Issue: 97(4), P. 1767 - 1793

Published: April 29, 2024

Abstract The use of semiochemical-baited traps for detection, monitoring, and sampling bark beetles woodboring (BBWB) has rapidly increased since the early 2000s. Semiochemical-baited survey are used in generic (broad community level) specific (targeted toward a species or group) surveys to detect nonnative potentially invasive BBWB, monitor established populations damaging native species, as tool natural communities various purposes. Along with expansion use, much research on ways improve efficacy trapping detection pests well BBWB general been conducted. In this review, we provide information intrinsic extrinsic factors how they influence detecting traps.

Exploiting common senses: sensory ecology meets wildlife conservation and management

Conservation Physiology, Journal Year: 2021, Volume and Issue: 9(1)

Published: Jan. 1, 2021

Abstract Multidisciplinary approaches to conservation and wildlife management are often effective in addressing complex, multi-factor problems. Emerging fields such as physiology behaviour can provide innovative solutions strategies for target species systems. Sensory ecology combines the study of ‘how animals acquire’ process sensory stimuli from their environments, ecological evolutionary significance respond’ this information. We review benefits that bring by discussing case studies across major taxa modalities. Conservation practices informed a approach include amelioration traps, control invasive species, reduction human–wildlife conflicts relocation establishment new populations endangered species. illustrate facilitate understanding mechanistic physiological explanations underlying particular issues also help develop ameliorate

Exploiting trap color to improve surveys of longhorn beetles

Journal of Pest Science, Journal Year: 2020, Volume and Issue: 94(3), P. 871 - 883

Published: Dec. 7, 2020

Abstract Longhorn beetles are commonly moved among continents within wood packaging materials used in trades. Visual inspections carried out at points of entry often fail to detect exotic longhorn as infested may have little or no sign colonization. Black-colored traps baited with pheromones and host volatiles thus improve chances detection. Here we tested whether existing surveillance protocols for can be further improved using trap colors different than black. Baited eight (i.e., grey, yellow, green, red, blue, brown, purple black) were deployed a randomized complete block design 16 sites northern Italy 2019. A total 6,001 individuals from 56 beetle species trapped. In general, yellow blue caught significantly higher number black traps. addition, color affected richness abundance the subfamily level, mixed response mostly linked habit visiting flowers food. Flower-visiting mainly exhibited clear preference flower-related colors, i.e., green whereas non-flower-visiting more attracted by dark long-wavelength-dominated like red brown. Our results clearly indicate that generic programs should not rely exclusively on use strongly chance detecting native potentially

Climatic and management‐related drivers of endemic European spruce bark beetle populations in boreal forests

Journal of Applied Ecology, Journal Year: 2024, Volume and Issue: 61(4), P. 809 - 820

Published: Feb. 15, 2024

Abstract Climate change is already reducing carbon sequestration in Central European forests dramatically through extensive droughts and bark beetle outbreaks. Further warming may threaten the enormous reservoirs boreal northern Europe unless disturbance risks can be reduced by adaptive forest management. The spruce ( Ips typographus ) a major natural agent spruce‐dominated overwhelm defences of healthy trees pheromone‐coordinated mass‐attacks. We used an dataset trap counts to quantify how climatic management‐related factors influence population sizes forests. Trap data were collected during period without outbreaks thus identify mechanisms that drive populations towards outbreak thresholds. most significant predictors size volume mature spruce, extent newly exposed clearcut edges, temperature soil moisture. For edge, moisture, 3‐year time lag produced best model fit. demonstrate incorporating predictors, with lag, useful management tool allowing spatial prediction future sizes.

Blends of Pheromones, With and Without Host Plant Volatiles, Can Attract Multiple Species of Cerambycid Beetles Simultaneously

Journal of Economic Entomology, Journal Year: 2018, Volume and Issue: 111(2), P. 716 - 724

Published: Jan. 5, 2018

Pheromone components of cerambycid beetles are often conserved, with a given compound serving as pheromone component for multiple related species, including species native to different continents. Consequently, single synthesized may attract trap simultaneously. Furthermore, our previous research in east-central Illinois had demonstrated that pheromones can be combined an even greater diversity species. Here, we describe the results field bioassays northeastern, midwestern, southeastern, south-central, and southwestern United States assessed attraction cerambycids 'generic' blend containing six known components, versus individual blend, how was influenced by plant volatiles. Nineteen were attracted significant numbers, attracting about twice many any components. The three subfamilies, whereas within one subfamily. However, some antagonistic interactions between identified. volatiles ethanol α-pinene usually enhanced blend. Taken together, these experiments suggest blends pheromones, if selected carefully minimize inhibitory effects, effective sampling generally enhance attraction. Such generic serve economical method detecting incursions exotic, potentially invasive

Insight into the Relationships Between Chemical, Protein and Functional Variables in the PBP/GOBP Family in Moths Based on Machine Learning

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(5), P. 2302 - 2302

Published: March 5, 2025

During their lives, insects must cope with a plethora of chemicals, which few will have an impact at the behavioral level. To detect these use several protein families located in main olfactory organs, antennae. Inside antennae, odorant-binding proteins (OBPs), as most studied family, bind volatile chemicals to transport them. Pheromone-binding (PBPs) and general-odorant-binding (GOPBs) are two subclasses OBPs evolved moths putative role. Predictions for OBP-chemical interactions remained limited, functional data collected over years unused. In this study, chemical, were curated, related datasets created descriptors. Regression algorithms implemented performance evaluated. Our results indicate that XGBoostRegressor exhibits best (R2 0.76, RMSE 0.28 MAE 0.20), followed by GradientBoostingRegressor LightGBMRegressor. our knowledge, is first study showing correlation among data, particularly context PBP/GOBP family moths.
