土蜂是金龟子的重要天敌,在寄生金龟子时是成虫钻入土中寻找金龟子幼虫寄生,故寄主与寄生的关系不明。我们曾对北京郊区土蜂科scoliidae某些种的寄主做了初步调查,其中对大斑土蜂Scoliaclypeata Sickman生物学及寄主做了一些观察。在我国尚属初次报道。 大斑土蜂在北京自然条件下6月下旬始见,终见期在9月末或10月上旬。蜜源植物有柽柳Tamarix chinensis Lour.(柽柳科)、薄荷Mentha arvensls L.(唇形科)、留兰香Mentha spicata L.(唇形科)、草木樨Melilotus suaveolens Ledeb.(豆科)、苜蓿Medicago sativa L.(豆科)、一枝黄花Solidagosp.(菊科)、金光菊Rudbeckia laciniata var.hortensia Bailey(菊科)、旱柳Salix matsudana Koidz.(杨柳科)、荆条Vitex negundo L.var.heterophylla(Frauch.)Rehd.(马鞭草科)。
Bumblebee is an important predator of chafer, parasites scarabs are adults drilling into the soil looking for beetle larvae parasites, so the relationship between host and parasites unknown. We conducted a preliminary investigation of the host species of some species of Scoliidae in the suburb of Beijing. Some observations were made on the biology and hosts of Scoliaclypeata Sickman. It is still the first time in our country. Large bumblebee in Beijing natural conditions in the beginning of June saw, the final period in late September or early October. The source plants are Tamarix chinensis Lour., Mentha arvensls L., Mentha spicata L., Melilotus suaveolens Ledeb., Medicago sativa L. (legume), Solidagosp. (Compositae), Rudbeckia laciniata var. hortensia Bailey (Asteraceae), Salix matsudana Koidz (Salix matsudana Koidz.), Vitex negundo L.var.heterophylla ( Frauch.) Rehd. (Verbenaceae).
