Humans and insects inhabit very different perceptual worlds, so human experimenters need to be aware of their biases when investigating insect behaviour. In applied entomology have been a barrier the rational design, manufacture, improvement pest control devices that effectively exploit visual This review describes how influence bias on this area is being reduced by our expanding understanding perception use modelling methods, highlights several important challenges are yet overcome.

Opsin mutants alter host plant selection by color vision in the nocturnal invasive pest Tuta absoluta

International Journal of Biological Macromolecules, Год журнала: 2024, Номер 265, С. 130636 - 130636

In insects, vision is crucial in finding host plants, but its role nocturnal insects largely unknown. Vision involves responses to specific spectra of photon wavelengths and opsins plays an important this process. Long-wavelength sensitive opsin (LW opsin) blue-sensitive (BL are main visual proteins play behavior regulation.We used CRISPR/Cas9 technology mutate the long-wavelength-sensitive blue wavelength-sensitive genes explored invasive pest Tuta absoluta. Light wave experiments revealed that LW2 (−/−) BL(−/−) mutants showed abnormal wavelength tropism. Both BL mutations affected preference T. absoluta for green environment. Mutations necessary inhibit attraction. The elimination leaf moths both induced a white plants. Behavioral changes resulting from LW2(−/−) were not by sense smell, further supporting regulatory insect behavior. To best our knowledge, first study reveal vision, host-seeking at night, which key factors. These findings will drive development "vision-ecology" theory.

Looking across the gap: Understanding the evolution of eyes and vision among insects

BioEssays, Год журнала: 2024, Номер 46(5)

Abstract The compound eyes of insects exhibit stunning variation in size, structure, and function, which has allowed these animals to use their vision adapt a huge range different environments lifestyles, evolve complex behaviors. Much our knowledge eye development been learned from Drosophila , while visual adaptations behaviors are often more striking better understood studies other insects. However, recent insects, including bees, beetles, butterflies, have begun address this gap by revealing the genetic developmental bases differences morphology key new aspects structure function. Furthermore, technical advances facilitated generation high‐resolution connectomic data insect species that enhances understanding information processing, impact changes processes on evolution behavior. Here, we review breakthroughs propose future integrated research function systems within among represents great opportunity understand remarkable diversification vision.

Morphology and spectral sensitivity of long visual fibers and lamina monopolar cells in the butterfly Papilio xuthus

The Journal of Comparative Neurology, Год журнала: 2024, Номер 532(2)

Abstract Extensive analysis of the flower‐visiting behavior a butterfly, Papilio xuthus , has indicated complex interaction between chromatic, achromatic, and motion cues. Their eyes are spectrally rich with six classes photoreceptors, respectively sensitive in ultraviolet, violet, blue, green, red, broad‐band wavelength regions. Here, we studied anatomy physiology photoreceptors second‐order neurons P. focusing on their spectral sensitivities projection terminals to address where early visual integration takes place. We thus found blue all terminate distal region second optic ganglion, medulla. identified five types based arborization first lamina, shape medulla terminals. sensitivity is independent morphological but reflects combination pre‐synaptic photoreceptors. The results indicate that most plausible for integration.
