摘要:

樱桃实叶蜂幼虫蛀食野生樱桃幼果,导致樱桃提前落果。国内多个省区有报道樱桃实叶蜂危害严重,但其种类均尚待澄清。本文记述采自甘肃省、幼虫蛀食大樱桃幼果的叶蜂科一新种:武氏樱实叶蜂Analcellicampa wui Niu & Wei,sp.nov.。本种与陕西、河南、湖北、湖南、四川等地分布的丹凤樱实叶蜂近似,其区别是:各足基节端部、转节全部和后足胫节大部黄褐色,触角第2节浅褐色;中胸胸腹侧片被毛,无明显光裸区;前翅Sc脉游离段位于1M脉上端内侧并远离1m脉,R+M脉段等长于1m-cu脉,显著短于1M脉;后翅2A脉很短,约等长于cu-a脉;腹部第1背板缺口深三角形,内缘直;锯腹片亚端部锯节明显宽于中部锯节,中部锯节节缝显著,锯基腹索踵宽大。对3种樱实叶蜂的COI基因进行测序,其中武氏樱实叶蜂与丹凤樱实叶蜂COI序列的K2P距离为7.29%,武氏樱实叶蜂与黄褐樱实叶蜂COI序列的K2P距离为8.54%。为方便害虫鉴定,提供实叶蜂族分属检索表和3种樱实叶蜂分种检索表。

Abstract:

The larvae of Analcellicampa spp. (Hymenoptera, Tenthredinidae) are fruit borer of Cerasus spp. (Rosaceae). It has been reported in many provinces and regions in China that Cerasus spp. fruits are damaged severely by sawfly borers, but the name of the sawfly was unknown or misidentified. In this paper, a new species of Tenthredinidae collected from Gansu, Analcellicampa wui Niu & Wei, sp. nov., the larvae bore and eat the young fruits of Cherry, is described. The new species, A. wui, is similar to A. danfengensis (Xiao, 1994) from Shaanxi, Henan, Hubei and Hunan Provinces but differs from the latter by the followings: the apex of each coxa and entire trochanter yellowish brown; the hind tibia largely and antennomere 2 pale brown; the epicnemium of mesepisternum pilose and without naked area; the free abscissa of vein Rs basad the apex of vein 1M and remote from it, vein R+M as long as 1m-cu and much shorter than vein 1M; vein 2A of hind wing very short and about as long as cu-a; the abdominal tergite 1 deeply and triangularly incised with inner margins almost straight; lancet with large tangium, middle segments with distinct annuli and narrower than subapical segments. The K2P distance between the COI sequences of A. wui and A. danfengensis, and between those of A. wui and A. xanthosoma, are 7.29% and 8.54% respectively. A key to genera of Hoplocampini and 3 known Chinese species of Analcellicampa are also provided to facilitate the identification of the pests.
