Adult Tea Green Leafhoppers, Empoasca onukii (Matsuda), Change Behaviors under Varying Light Conditions.

摘要: Insect behaviors are often influenced by light conditions including photoperiod, intensity, and wavelength. Understanding pest insect responses to changing may help with developing alternative strategies for control. Little is known about the behavioral of leafhoppers (Hemiptera: Cicadellidae) conditions. The behavior tea green leafhopper, Empoasca onukii Matsuda, was examined when exposed different photoperiods or wavelengths. Observations included frequency locomotion cleaning activities, duration time spent searching. results suggested that under normal photoperiod both female male adults were generally more active in darkness (i.e., at night) than light. In continuous (DD), events Period 1 (7:00–19:00) significantly increased, compared (LD). Leafhoppers, especially females, changed their patterns a two day cycle DD. Under illumination (continuous quartz lamp light, yellow night, night), activities locomotion, cleaning, searching suppressed during night (19:00–7:00) females males increased (7:00–19:00), suggesting shift circadian rhythm. Our work suggests changes conditions, wavelength, can influence leafhoppers, potentially affecting other life history traits such as reproduction development, serve method leafhopper
