研究不同温度对三星黄萤叶甲(Paridea angulicollis Motschulsky)幼虫、成虫取食量的影响.结果表明,在26℃时幼虫、成虫取食量最大,幼虫期总取食量为9.99 mg,雌性成虫日取食面积为60,51 mm2、雄性成虫则为55.28 mm2;23℃和29℃时幼虫、成虫取食量次之.温度过高或过低均抑制幼虫、成虫的取食.与幼虫相比,成虫取食受温度影响较大,且雌虫取食量大于雄虫.在此基础上,建立温度与取食量之间的模型,经检验能较好拟合试验数据.
Effect of Temperature on the Feeding of Paridea angulicollis Motschulsky
The effect on the feeding of Paridea angulicollis Motschulsky larvae and adult was studied at different temperature rates, the result indicated that the maximum feeding amount of larvae and adult was detected at 26 ℃. The feeding amount of the larvae was 9. 99 mg,the daily feeding area of the female and male were 60. 51 mm2 and 55. 28 mm2, respectively. Less appropriate temperature was 23 ℃ and 29 ℃. The feeding of the larvae and adult was suppressed at the high or low temperature. Compared with the larvae,the leaf area of the adult consumption influenced obviously by temperature, the leaf area of the female consumption was greater than that of the male. The models between the temperature and the daily consumption leaf area for the adult male and female were constructed.
