| Housefly (Musca domestica) maggots with different instars and under different culture conditions were
stimulated at different temperature, supplemented by a certain time of recovery training, and then the antibacterial activity
was measured. The results showed that the appropriate degree of heat shock could significantly improve the antibacterial
ability, and had different effects on the antibacterial ability by different temperatures, different hot shock time, different
recovery time after heat shock, and different instar maggot. The optimum condition was 10 min at 65益heat shock
treatment, and then recovery for 3 h at 22益. The antibacterial activity increased by about 53 times under the condition
compared to the control. Multiple batch repeatable experiments for different materials showed that the treatment had good
reproducibility and high stability for the optimum condition. Different handling capacity test showed that heat treatment for
large quantities of material would cause the efficiency and stability for induction effect of antibacterial activity getting
lower; however, appropriate packaging for bulk material could effectively solve this problem. |
