大豆品种(系)和种植密度对豆天蛾幼虫存活及生长发育的影响

豆天蛾Clanis bilineata tsingtauica Mell幼虫，是一种食用昆虫，富含蛋白质、维生素和矿质元素，具有很高的营养、药用和经济价值。了解适宜豆天蛾幼虫生长发育的大豆品种（品系）和种植密度，可为豆天蛾幼虫规模化饲养提供理论基础。研究通过设置两因素裂区实验，在10个品种（品系）大豆和2个种植密度水平下，测定豆天蛾幼虫生物学参数，明确适宜豆天蛾幼虫养殖的大豆品种（品系）和种植密度。结果表明，不同大豆品种（系）和种植密度对豆天蛾幼虫存活及生长发育均有显著影响；其中使用连151、淮豆9号、东辛3号和H0573大豆饲养的豆天蛾幼虫产量和存活率较高，虫体长度较长，发育历期较短；大青豆饲养的豆天蛾幼虫产量较低，幼虫发育整齐度较差，发育历期长。当种植密度为40 cm×30 cm时，豆天蛾幼虫存活和发育历期整齐度均显著高于种植密度40 cm×15 cm。综上所述，较适宜豆天蛾幼虫养殖的大豆品种（品系）为连151、淮豆9号、东辛3号和H0573，种植密度为40 cm×30 cm。

Effects of soybean varieties (lines) and planting density on survival and development of larvae of Clanis bilineata tsingtauica Mell

Larvae of Clanis bilineata tsingtauica Mell is rich in protein, vitamins and minerals as an edible insect. It has high nutritional, medical and economic value and could provide theoretical basis in mass rearing procedure through finding out opportune soybean varieties (lines) and planting density during growth and development of larvae of Clanis bilineata tsingtauica Mell. To define the opportune soybean varieties (lines) and planting density, the study was conducted by setting up a two-factor split plot experiment and measuring biological characteristics of larvae of Clanis bilineata tsingtauica Mell under the codition of 10 soybean varieties (lines) and 2 planting densities. The main results were as follows: There were significantly influences of different soybean varieties (lines) and planting density on sunrvival and growth of larvae of Clanis bilineata tsingtauica Mell. There was a high level of yield, survival rate and body length of larvae of Clanis bilineata tsingtauica Mell under the raising condition of Lian 151, Huaidou 9, Dongxin 3 and H0573, which existed shorter developmental duration. While there were lower yield and larval developmental uniformity and the longest developmental duration of larvae of Clanis bilineata tsingtauica Mell under the raising condition of Big green soybean. The survival and uniformity of developmental duration under 40 cm×30 cm planting density were all significantly higher than under 40 cm×15 cm planting density. Through comprehensive analysis of above, the suitable culture of larvae of Clanis bilineata tsingtauica Mell breeding were Lian 151, Huaidou 9, Dongxin 3 and H0573 with 40 cm×30 cm planting density.
