Here, we investigated empirically the potential of boosting the SIT using spores of the entomopathogenic fungus, <i>Metarhizium anisopliae</i>. Laboratory bioassay confirmed the transmission potential of the fungus from inoculated males to males and females, with subsequent reductions in survival and fecundity. Inoculation, like sterility, nonetheless reduced male mating success. Semi-field tests (i.e., large outdoor cages) revealed greater costs of fungal inoculation on male competitivity than observed in the laboratory. Combined with effects of inoculation on male survival, these costs led to a lower reduction in female reproduction in the presence of inoculated sterile males compared to plain sterile males. As tested here, boosting the SIT with <i>M. anisoplae</i> spores to control <i>B. dorsalis</i> could reduce its efficacy.

In no-choice tests and contact-fumigation bioassays on third instar larvae, clove bud, fennel sweet, and lemongrass oils exhibited notable activities. Still, no direct correlation between insecticidal activity and feeding deterrence was observed. Second instar larvae were pre-exposed to those active oils to test the habituation effect. Larvae reared with lemongrass and clove bud oils showed gustatory habituation, whereas those with fennel sweet oil did not show any desensitization compared to the control. Comparable outcomes were observed in individuals exposed to the main constituents of the three oils. Additionally, the mixture of fennel sweet and clove bud oils showed a synergistic feeding deterrent effect. However, although statistically insignificant, potential habituation for the mixture was observed, and only robust inhibition of habituation was expected at physiologically high concentrations (FDI₉₀ + FDI₉₀). Electrophysiological studies showed that the response of the maxillary palp to citral decreased in the experienced group, while to <i>trans</i>-anethole, it was maintained at levels similar to the naive group.

Exposure of water to cold plasma significantly lowered pH and increased concentrations of H₂O_2, NO₂⁻, and NO₃⁻.

Preference bioassays revealed significant avoidance of settling and reduced oviposition by two-spotted spider mites on leaf discs from PAW-irrigated plants compared to those from untreated control plants. Performance bioassays showed a significant decrease in two-spotted spider mite populations on PAW-irrigated plants. Results presented in this study provide comprehensive support to the hypothesis that indirect effects of supplementary PAW irrigation significantly reduce host plant suitability to two-spotted spider mites. PAW 6.0 may be slightly better than PAW 9.4, and this difference in performance is discussed in this study.

Using the age-stage two-sex life table theory, we evaluated the impact of imidacloprid on the life table of the <i>O. similis</i> population. The results showed that the LC₁₀ and LC₂₀ values for each developmental stage of <i>O. similis</i> were lower under contact treatment than those under stomach toxicity treatment.

The results also indicated that the peak value of age-stage-specific fecundity of <i>O. similis</i> was delayed by 1–2 days after imidacloprid treatment. Predictions for population growth of <i>O. similis</i> under unrestricted conditions showed that at 60 days, the population size of the control treatment was 2.06 times and 3.20 times that of LC₁₀ contact and stomach toxicity treatment, respectively.

The aim of this study is to evaluate the effectiveness of adulticide spraying conducted at different times of the day to curb DENV transmission. Based on unique dataset of <i>Aedes aegypti</i> diel activity patterns in Miami-Dade County, Florida, and Brownsville, Texas, we developed a mechanistic model of DENV transmission, which simulates adulticide spraying interventions.

Moreover, in case of a local outbreak in Miami-Dade County, we estimated the median number of symptomatic infections after the identification of a local outbreak to be reduced from 67.0 (IQR: 25.5–103.0) in the absence of interventions to 1.0 (IQR: 0.0–2.0) when spraying adulticide for 14 consecutive days at 8 pm.

Models of pest response to temperature are integral to pest risk assessment and management, helping to inform surveillance and control measures. The widespread use of meteorological data as predictors in these models compromises their reliability as these measurements are not thermally coupled to the conditions experienced by pest organisms or their body temperatures. Here, we present how mechanistic microclimate models can be used to estimate the conditions experienced by pest organisms to provide significant benefits to pest risk modelling. These well-established physical models capture how landscape, vegetation and climate interact to determine the conditions to which pests are exposed. Assessments of pest risk derived from microclimate conditions are likely to significantly diverge from those derived from weather station measurements. The magnitude of this divergence will vary across a landscape, over time and according to pest habitats and behaviour due to the complex mechanisms that determine microclimate conditions and their effect on pest biology. Whereas the application of microclimate models was once restricted to relatively homogeneous habitats, these models can now be applied readily to generate hourly time series across extensive and varied landscapes. We outline the benefits and challenges of more routine application of microclimate models to pest risk modelling. Mechanistic microclimate models provide a heuristic tool that helps discriminate between physical, mathematical and biological causes of model failure. Their use can also help understand how pest ecology, behaviour and physiology mediate the relationship between climate and pest response.</p>","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"16 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140903015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The males are strongly attracted to methyl eugenol (ME). After consumption, ME is converted to metabolites that act as sex pheromones, which increase mating success. ME lure is instrumental in male annihilation technique (MAT) and sterile insect technique (SIT) applications to suppress or eradicate fruit fly populations. A simultaneous MAT-SIT concept is proposed to reduce operational costs and time-to-eradication. However, sterile males released to the field may respond to MAT’s ME-baited traps, reducing the efficacy of SIT. Here, we developed a ME-supplemented diet that reduces males’ response to ME without compromising mating efficiency and survivorship. We offered sugar-yeast diet supplemented with ME (0–5%) to 5-day-old males for 48 h and evaluated their response to ME, mating performance and pheromone production at 3-, 7-, 11- and 15-days post-treatment (DPT), while observing mortality for 60-DPT. Our results indicate that consuming a ME-supplemented diet reduces response to ME lures and enhances mating success, with the 5% ME diet showing the most promising results. The trend of pheromone production at different DPT after consuming various ME-supplemented diets corroborated with those of reduced lure response and mating enhancement. Although diet containing 3 and 5% ME affected males’ survival probability over 60-DPT, the treatment does not impact the survival of all treated males for at least 25-DPT.
