| 中文摘要:为明确丽草蛉Chrysopa formosa对柑橘木虱Diaphorina citri成虫的生物防控潜能，在实验室条件下测定丽草蛉1、2、3龄幼虫和成虫对柑橘木虱成虫的捕食功能、搜寻效应及其种内干扰效应，并测定其对不同猎物的捕食偏好。结果显示，丽草蛉1~3龄幼虫和成虫对柑橘木虱成虫均有捕食行为，捕食功能反应均符合Holling II模型。丽草蛉1、2、3龄幼虫和成虫对柑橘木虱成虫的瞬时攻击率分别为0.247、0.393、0.769和0.509，处理时间分别为0.228、0.048、0.015和0.013 d，理论日最大捕食量分别为4.386、20.833、66.667和76.923头，控害效能分别为1.083、8.188、51.267和39.154。各虫态丽草蛉对柑橘木虱成虫的搜寻效应均随着猎物密度的增加而降低，其中3龄丽草蛉幼虫的搜寻效应下降趋势最大。当柑橘木虱成虫密度固定时，单头丽草蛉的日捕食量随柑橘木虱密度的增加而逐渐降低，其捕食作用受到自身密度的干扰，干扰效应方程为E=0.260P-0.351。当存在柑橘木虱与豌豆蚜Acyrthosiphon pisum两种捕食对象时，丽草蛉3龄幼虫偏好捕食柑橘木虱。表明丽草蛉1~3龄幼虫和成虫对柑橘木虱成虫均有一定的防控能力，其3龄幼虫和成虫对柑橘木虱成虫的防控能力大于1、2龄幼虫。 |

| Abstract:To investigate the potential of beautiful lacewing Chrysopa formosa for controlling the adult of Asian citrus psyllid Diaphorina citri, the predatory functional response, searching efficiency, intraspecific interference and predation preference of C. formosa at the 1st, 2nd, 3rd instar larva and adult stages against the adult of D. citri were studied under laboratory conditions. The results showed that all stages of C. formosa preyed on the adult D. citri, and the functional response of all stages of C. formosa fitted the Holling II model. The instant attack rates of 1st, 2nd, 3rd instar larvae and adults of C. formosa against D. citri were 0.247, 0.393, 0.769 and 0.509, respectively; the handling time was 0.228, 0.048, 0.015 and 0.013 d, respectively; the maximum daily consumptions were 4.386, 20.833, 66.667 and 76.923 individuals, respectively, and the predation capacity were 1.083, 8.188, 51.267 and 39.154, respectively. The searching efficiency of C. formosa decreased with increasing density of D. citri, and the 3rd instar of C. formosa showed the most obvious decline. Under a given density of D. citri, the individual daily predation rate of the 3rd instar of C. formosa decreased with increasing density of itself. The predation of C. formosa was interfered by its own density, and the interference equation was E=0.260P-0.351. When both the adult of D. citri and the adult of Acyrthosiphon pisum were available, the 3rd instar of C. formosa showed a predation preference to D. citri. This study indicated that all stages of C. formosa had a good potential for controlling the adult of D. citri, and the 3rd instar and adult of C. formosa had a better pest control potential than the 1st and 2nd larvae. |
