“…Whether the difference of phototaxis between male and female adults of E. castanea is related to compound eye structure, photosensitive mechanism, and opsin needs to be further studied in the future. On the other hand, we found that the difference of phototaxis between females and males in this study was not as large as that in the field [27], which may be related to the development, flight ability, mating status, and living habits of males and females. It needs to be confirmed by further research.…”

The phototaxis of insects is closely related to light source factors, such as spectrum and light intensity. The cane grub, Exolontha castanea Chang (Coleoptera: Melolonthidae), is an important underground pest of sugarcane in Guangxi province of China. To clarify the effect of spectral sensitivity and light intensity response on the phototactic behavior of E. castanea, the phototactic behavior responses of male and female adults to 13 monochromatic lights in the wavelength range of 365–630 nm and different light intensities were measured. We found that both male and female adults had positive phototaxis to 13 monochromatic lights. The phototactic response rate of males and females at ultraviolet and violet light was the highest in the wavelength range of 365–420 nm. Among them, the most sensitive spectrum of females and males was at 365 nm and 420 nm, respectively. From the intensity response of phototactic behavior to different spectrum, the G1 (strong phototaxis) response rates of females at 365 nm and males at 420 nm were the highest. In addition, the phototactic response rate of females and males increased with the light intensity, showing a significant positive correlation. This study showed that the spectrum and light intensity were the key factors affecting the phototactic behavior of E. castanea. The sensitive spectrum of males and females were different, with a similar trend in phototaxis.

“…Females accounted for more than 95% of the total adults trapped. However, this phenomenon was independent of the number of male and female individuals in the natural population [27]. At present, the mechanism of phototaxis difference between males and females of E. castanea is not clear.…”

“…In severe situations, about 70% of sugarcane seedlings are infested. Numerous cane grub species can cause damages to sugarcane roots, which drastically reduces the yield (10%–20%) loss and sugar content ( Shang et al., 2022 ). Guangxi has 20 counties, which are affected by pests, with Baise and Hechi experiencing the worst infestations and Yichou having a seedling mortality rate exceeding 40%.…”

“…Ratoon populations were more severely affected than sugarcane plantations ( Shang et al., 2014 ). Another grub called Exolontha castanea feeds on sugarcane, which results in lodging, drying, and losses of 32% and 23.3% in sugarcane production ( Shang et al., 2016 ). Grubs feeding on the roots of seedlings cause gaps in the field at the establishment stage.…”

Environmental stresses are the main constraints on agricultural productivity and food security worldwide. This issue is worsened by abrupt and severe changes in global climate. The formation of sugarcane yield and the accumulation of sucrose are significantly influenced by biotic and abiotic stresses. Understanding the biochemical, physiological, and environmental phenomena associated with these stresses is essential to increase crop production. This review explores the effect of environmental factors on sucrose content and sugarcane yield and highlights the negative effects of insufficient water supply, temperature fluctuations, insect pests, and diseases. This article also explains the mechanism of reactive oxygen species (ROS), the role of different metabolites under environmental stresses, and highlights the function of environmental stress-related resistance genes in sugarcane. This review further discusses sugarcane crop improvement approaches, with a focus on endophytic mechanism and consortium endophyte application in sugarcane plants. Endophytes are vital in plant defense; they produce bioactive molecules that act as biocontrol agents to enhance plant immune systems and modify environmental responses through interaction with plants. This review provides an overview of internal mechanisms to enhance sugarcane plant growth and environmental resistance and offers new ideas for improving sugarcane plant fitness and crop productivity.
