柑橘大实蝇复眼结构及趋色光谱
Compound eye structure and spectral sensitivity of Chinese citrus fruit fly Bactrocera minax
摘要
Abstract
To elucidate the color preference and its physiological basis in Chinese citrus fruit fly Bactro-cera minax,we conducted both field and greenhouse assays to assess the fruit flies'behavioral responses to color stimuli.Paraffin,semithin,and ultrathin sections of compound eyes of the flies were generated,and their internal structures were examined using a super-depth microscope and transmission electron microscopy.In addition,electroretinogram(ERG)recordings were performed to determine the spectral sensitivity of the compound eyes.Results showed that in citrus orchards,green spherical traps captured an average of 23.00 flies,significantly higher than the 7.43 flies captured by yellow traps.In the greenhouse,the capture rate of green traps reached 40.87%,compared with 15.87%for yellow traps,indicating a highly significant difference.The compound eyes of B.minax were composed of aggre-gated ommatidia,with approximately 56 corneal lamellae,and rhabdomeres arranged in a dispersed pat-tern.ERG analysis revealed two sensitivity peaks in both sexes:a major peak in the green wavelength region and a secondary peak in the ultraviolet region.Female flies peaked at 529.8 nm and 373.5 nm,while males peaked at 529.8 nm and 374.7 nm.These findings indicate that the green preference of B.minax is closely linked with the structural features of their compound eyes and the physiological traits of their photoreceptor cells.关键词
