Abstract:From August to October in 2018, the economic threshold of the countermeasures of the wild boar (Sus scrofa) damages has been carried out using the sound of the Amur tiger (Panthera tigris altaica), the screaming of S. scrofa and the solar blinker in Hunchun Area, Jilin Province. Four experimental groups (5 plots per group) including the sound of the screaming of P. t. altaica (15 s), S. scrofa (15 s) and superposition of them (30 s) with 5 min interval repeatedly (group A), the sound of P. t. altaica for 1 min with 5 min interval (group B), the 1 000 mA red solar blinker (group C) and blank matched group (group D), were set. All the plots were set in the farmland adjacent to the forest. The sounds were played continuously from dusk to dawn, and the solar blinker was controlled by light switch. The damage of S. scrofa within 24 h on farmland within 50 m of the countermeasures was recorded from 07:00 to 07:30 each day. The effect of countermeasures was analyzed by Mann-Whitney U test, and the relationship between corn (Zea mays) loss rate and the number of S. scrofa were analyzed by the regression fitting analysis. The results showed that: (1) There were significant differences in the validity period between the experimental groups and the control group (P=0.001). The validity periods of groups A and C were longer (27.00 d±1.87 d and 31.80 d±3.56 d) than the control group (1.80 d±0.75 d); (2) The corn loss rate (4.41%±2.24%) and economic loss (639.04 yuan±289.15 yuan) were the lowest in group A, while the highest values were detected in the control group (48.33%±5.42% and 6 703.38 yuan±412.20 yuan, respectively); (3) The regression equation between the loss rate of corn (y) and the number of S. scrofa (x) was y=0.095-0.116x+0.048x2; (4) When the number of S. scrofa per hectare reached 2.09±0.28 and 2.15±0.18, the countermeasures in groups A and C should be taken respectively. This study provides a reference for the effective control of S. scrofa damages and the decrease in the management cost and also contributes to the research on the other wildlife damage control.
