摘要
对广西蔗区蠼螋种类的发生与分布进行了调查。结果表明,广西蔗区蠼螋主要有3种:黄足肥螋,黄翅绵跗螋和一种待鉴定的灰色蠼螋。其中,黄足肥螋和黄翅绵跗螋在调查的12个广西蔗区均有分布,而灰色蠼螋则在部分蔗区发现。蠼螋发生量初步调查结果表明,江洲区的蠼螋发生量较大,甘蔗生长前期百株蠼螋量为30.7头,在甘蔗生长中、后期高达98头。在各个蔗区,甘蔗生长中、后期蠼螋发生量均明显高于甘蔗生长前期,并且在同一蔗地甘蔗生长前期和中、后期的蠼螋种类以及其各自发生量所占比列亦有区别。
Occurrence and distribution of earwigs were investigated in Guangxi sugarcane planting areas. The results showed that there were three main species of earwigs, Euborellia pallipes Shiraki, Proreus simulans St覽l and one grey earwig（unidentified）. E. pallipes and P. simulans were distributed widely in 12 areas investigated, while the grey earwigs were only found in partial areas. Preliminary survey of quantity revealed that the largest amount of earwigs occurred in Laituan of Chongzuo with about 30.7 individuals per 100 sugarcanes in early stage of plantation, up to 98 individuals in middle-late stage. And amount of earwigs in middle-late stage of sugarcane were significantly larger than that in early stage（May to June）. Species of earwigs and their proportion were different in early and late growth stage of sugarcane.
