摘要
为明确不同剂型的人工饲料对七星瓢虫成虫的影响,为进一步优化七星瓢虫人工饲料的制作方法提供参考,采用两种剂型(干湿分离和微胶囊)人工饲料对七星瓢虫成虫进行饲喂,测定取食频次、取食量、交配频次、产卵频率和产卵量。研究结果表明:七星瓢虫成虫对干湿分离饲料的平均取食频次(0.72头/min)显著低于对微胶囊饲料的取食频次(1.58头/min),但干湿分离饲料组七星瓢虫成虫的平均取食量(0.04 g/对)显著高于微胶囊饲料组(0.02 g/对);干湿分离饲料组和微胶囊饲料组的平均交配频次无显著性差异;干湿分离饲料组的平均产卵频率、产卵量分别为19.00%、23.40粒/头,显著高于微胶囊饲料组的1.00%、2.40粒/头。总体来看,七星瓢虫成虫对两种剂型的人工饲料均能取食,干湿分离饲料更优于微胶囊饲料。
The effects of artificial diet formulation on the adults of Coccinella septempunctata were determined for the purpose of further optimization of the preparation of the artificial diets of C.septempunctata by feeding C.septempunctata adults with two formations,i.e.,dry-wet separation(DWS)and microcapsulation(MCS),of artificial diets and measuring the feeding frequency,food intake,mating frequency,oviposition frequency,and eggs deposition.The results showed that the feeding frequency of C.septempunctata adults on the DWS diet(0.72 insects/min)was significantly lower than that on the MCS diet(1.58 insects/min),but the feeding amount on the DWS diet(0.04 g/pair)was significantly higher than that on the MCS diet(0.01 g/pair).There was no significant difference in the mating frequency of C.septempunctata between the two groups.The oviposition frequency and egg deposition in the DWS diet group were 19.00%and 23.40 eggs/female,respectively,significantly higher than the values of 1.00%and 2.40 eggs/female in the counterpart,respectively.In general,the adults of C.septempunctata can feed on both formulations of artificial diet,but the dry-wet separation diet is better than the microcapsule diet.
