Abstract：In order to screen and select the insecticides with best control effect over Pantana simplex larvae for pollution-free P. simplex larvae control, the indoor virulence determination of insecticides and the prevention andcontrol experiments in forests were carried out in 2017 in Shaxian, Fujian Province, with 5 kinds of botanical insecticides over P. simplex larvae. The results of the indoor virulence determination showed that 1% Celangulins solution, 4% rotenone EC, 0.5% veratridine soluble liquid, 1.2% matrine nicotine missible soluble liquid, and matrine 1.5% LC50 solution of P. simplex larvae were 1.27, 1.06, 1.31, 0.482, 0.736 mg/L, respectively. The 5 kinds of botanical insecticides had the insecticidal effect on P. simplex larvae and the 1.2% matrine nicotine missible oil had the strongest toxicity on P. simplex larvae. The control test in forests showed that, 3 d after treatment, the control effect of 5 kinds of botanical insecticides were all above 90%, while the matrine type had the best chemical control effect, and the best concentration of 2 kinds of matrine agents are 1 500 times liquid; the 1 000 times liquid of 1% Celangulins solution and 0.5% veratridine soluble liquid concentration was the best use in the forest; the optimal concentration of 4% EC for best control effect was 1 200 times liquid. The 5 kinds of botanical insecticides tested had good insecticidal activity over P. simplex larvae, and could be used as pollution free and effect insecticides to prevent and control P. simplex larvae.
