Abstract BACKGROUND Phototactic behavior and oviposition site selection in phytoseiid predators are crucial for understanding their ecological interactions optimizing use agricultural pest management. This study investigated the phototactic responses preferences of seven species proven or potential importance biocontrol: Amblydromalus limonicus (Garman & McGregor), Amblyseius herbicolus (Chant), lentiginosus Denmark Schicha, Neoseiulus barkeri Hughes, cucumeris (Oudemans), womersleyi (Schicha), Phytoseiulus persimilis Athias‐Henriot. We hypothesized that these light as a cue, with aligning respective lifestyles. RESULTS By presenting adults two choices ( i.e. dark) acrylic arenas, we found P. exhibited significant preference light. In contrast, other showed no preference. The were similar between genders all six sexually reproducing tested this study. Furthermore, varied significantly among species. Gravid females As. , N. preferred dark sites egg laying, whereas Ad. preference, oviposition. CONCLUSION highlights an factor influencing suggests adaptations to specific environmental niches. These findings have practical implications enhancing effectiveness phytoseiids Further research should investigate mechanisms driving perception predators. © 2024 Society Chemical Industry.

Interactions Between High-Intensity Light and Unrestricted Vision in the Drive for Hyperopia

Investigative Ophthalmology & Visual Science, Год журнала: 2024, Номер 65(14), С. 22 - 22

Purpose: To evaluate the impact of optical vs. illuminance factors and their duration-dependency on lens-induced hyperopia (LIH) in chick eyes. Methods: Hyperopia was induced one eye chicks (10 groups; n = 126) from day 1 after hatching until 8 using +10-diopter lenses with fellow eyes as controls. One group served control without any interventions. The remaining groups were exposed to 2, 4, or 6 hours unrestricted vision (UnV), high-intensity light (HL; 15,000 lux), both (HL + UnV). Ocular axial length (AL), refractive error, choroidal thickness measured days 1, 8. Inter-ocular difference (IOD experimental − contralateral eye) ± SEM used express outcome measures. Results: By 8, LIH decreased AL (−0.42 0.03 mm) produced hyperopic refraction (+3.48 0.32 diopters) thickening (+85.81 35.23 µm) (all P < 0.001). Exposure UnV reduced (i.e., refraction, shortening, thickening) a duration-dependent manner, whereas HL potentiated development manner. When combined, overpowered HL, resultant being close alone, except at hours, when shorter compared alone (P 0.03). Conclusions: Daily exposure UnV, altered manner producing competing signals. signal generated by generally stronger than combined exposure, yet longer durations affected drive for emmetropization UnV.

Abstract Purpose Ambient light exposure is linked to myopia development in children and affects susceptibility animal models. Currently, it unclear which signals mediate the effects of on myopia. All- trans retinoic acid (atRA) dopamine (DA) oppositely influence experimental may be involved retino-scleral signaling cascade underlying myopic eye growth. However, how ocular atRA responds different lighting whether DA interact remains unknown. Methods Dark-adapted C57BL/6J mice (29-31 days old) were exposed Dim (1 lux), Mid (59 or Bright (12,000 lux) ambient for 5-60 minutes. Some also systemically administered precursor, LDOPA, prior exposure. After exposure, retina back-of-the-eye (BOE) collected analyzed levels atRA, DA, metabolite, DOPAC. Results turnover (DOPAC/DA ratio) increased magnitude after only five minutes higher luminance but was minimal BOE. In contrast, BOE significantly decreased with longer duration Intriguingly, LDOPA-treated had a transient reduction retinal compared saline-treated mice, whereas treatment no effect DA. Conclusions Ocular affected by Overall, these data suggest specific interactions between lighting, that could have implications
