对安吉竹博园内筛胸梳爪叩甲Melanotus cribricolls(Faldermann)的寄主危害进行调查,主要调查竹种隶属于刚竹属(Phyllostachys)、矢竹属(Pseudosasa)、大明竹属(Pleioblastus)、唐竹属(Sinobambusa)、短穗竹属(Brachystachyum)、少穗竹属(Oligostachyum)和箣竹属(Bambusa),共7个属,包括47个竹种,其中41种寄主都不同程度地受到筛胸梳爪叩甲幼虫期的危害,新发现受害寄主30余种。据筛胸梳爪叩甲幼虫在5个竹种林区间的空间分布表明:筛胸梳爪叩甲较大体型的幼虫在竹林土壤中主要为聚集分布。调查过程发现,除筛胸梳爪叩甲幼虫对竹种的危害以外,竹笋夜蛾Apamea spp.也是导致退笋的主要虫害之一,二者一并成为目前竹博园内竹笋退笋的主要害虫。此外,园内竹种也受到浙江栉蝠蛾Bipectilus zhejiangensi、叶甲、白蚁和腐生蝇的侵害。鉴于筛胸梳爪叩甲幼虫危害的竹种范围比以往报道的有扩大的趋势,在竹种移植、土壤改良及敏感品种的选育应考虑到这些方面。
To investigate the host damage of Melanotus cribricolls (Faldermann) in bamboo groves in Anji, the main species of bamboo belonging to Phyllostachys, Pseudosasa, Pleioblastus, Sinobambusa, Brachystachyum, Oligostachyum, and Bambusa, a total of seven genera, including 47 species of bamboo, of which 41 species of host were all sieved to varying degrees Breast cootstruck a larvae harm, the newly discovered victims host more than 30 species. According to the spatial distribution of the spermopod Larvae in five species of bamboo forest, the larger larvae of Larvae in the scripta were mainly aggregated in the soil of bamboo forest. During the investigation, Apamea spp. Was also one of the major insect pests causing the recovery of bamboo shoots, except for the damage caused by the squid thrips Larvae to bamboo species. Pests. In addition, bamboo species in the garden are also infested by Bipectilus zhejiangensi, leaf beetles, termites and saprophytic flies in Zhejiang Province. In view of the wide range of bamboo species harmed by the thorax, claw and rapamycin larvae, these aspects should be taken into consideration in bamboo species transplanting, soil improvement and breeding of sensitive species.
