家蚕摄食反应的个体差异研究

从同一蚕品种中通过人工饲料育选拔出摄食性高的个体与低的个体，探讨了其摄食反应的差异。结果表明，无论是对摄食刺激物质还是抑制物质，低食性蚕均比高食性蚕敏感，对无机盐、酸和水的感受性以及环境因子对摄食性的影响，也存在显著差异，但这种差异随着龄期增进而减小。据此，分析了提高家蚕对人工饲料摄食性和发育整齐度的有效途径。

STUDIES ON INDIVIDUAL DIFFERENCE OF SILKWORM IN FEEDING RESPONSE

Through artificial diet rearing,silkworm individuals with high and low feeding habit were selected respectively from the same variety and the individual difference of feeding response was studied. The result showed that whether to stimulant matters or to inhibit ing ones in the diet,the individuals with low feeding habit was more sensitive than the high ones. They also showed very obvious difference in the sensibility to inorganic salt,acid and water,and the response to environmental factors. But this difference decreased with the incresasing of instars. According to these, the effective solutions to improvefeeding habit and developmental uniformity of silkworm were analysed.
