2011~2013年对我国南方林区捕食性天敌昆虫日本佳盾蜾蠃Euodynerus nipanicus(Schulthess)的营巢生物学及其巢穴结构进行了初步研究。采用目测、拍照和摄像等方法对雌性日本佳盾蜾蠃的整个筑巢过程和日活动规律进行了连续观察,采用室内解剖巢管对该蜂的巢穴结构进行观测,用游标卡尺对虫室、空室和前庭大小等数据进行测量。研究发现日本佳盾蜾蠃偏爱巢口方向为东南方向的巢箱,长度为21.03±3.75 cm,内径为0.88±0.13 cm的巢管;该蜂巢穴主要包括虫室、空室和前庭三个部分,每个巢管虫室数目平均4.75±1.83个,长度平均1.32±0.26 cm,空室数目平均5.67±1.97个,长度平均0.91±0.29 cm,前庭只有1个但不同巢管中差异较大,平均长度2.57±1.74 cm;晴好天气下,雌性成蜂一天内共出巢55±5.33次,一次捕食过程平均536.97±110.76 s,每次存放食物时间平均40.15±8.46 s,一次采泥过程所需时间平均39.07±11.15 s,筑巢时间平均68.56±13.59 s。日本佳盾蜾蠃不同的个体之间筑巢习性基本相近,但不同巢穴内部结构存在一定的差异。
From 2011 to 2013, we conducted a preliminary study on the nesting biology and nests of Euodynerus nipanicus (Schulthess), a predatory insect predominate in southern China. The observation of the nesting process and daily activities of the Japanese female Juglans regia was carried out by using the method of visual observation, photographing and video recording. The anatomy of the lair of the bee was observed with indoor anatomical nests. Room and vestibular size and other data were measured. The study found that Japan Jiandu 蜾 蠃 preferred Nest box southeast direction nest box, a length of 21.03 ± 3.75 cm, an inner diameter of 0.88 ± 0.13 cm nest tube; the bee hive mainly includes three parts of the worm room, empty room and the vestibule , The average number of worms in each nests was 4.75 ± 1.83, the average length was 1.32 ± 0.26 cm. The number of empty chambers was 5.67 ± 1.97, the average length was 0.91 ± 0.29 cm. There was only one vestibule but different in different nests. The average length was 2.57 ± 1.74 cm. In fine weather, the females spent 55 ± 5.33 times per day in one day, the average time of one predation was 536.97 ± 110.76 s, and the average time for storing food was 40.15 ± 8.46 s, Time average 39.07 ± 11.15 s, nesting time average 68.56 ± 13.59 s. Japan Jiandu 蜾 蠃 different habitats between different individuals are similar, but there are some differences between the internal structure of different lairs.
