Large-scale brown moths in Shandong Rongcheng area 1a occurred a generation, with pupa in the soil overwintering. The beginning of April next year the adults began to emerge; female moths only one mating, male moths can be mated 1 or 2 times. Individual fecundity of 10 5 4 ~ 170 2 tablets. Egg stage 28 ~ 46d.

The results showed that: 2.5% deltamethrin, 10% cypermethrin EC 60 0 0, 50% monocrotophos EC 1500 times and 80% DDVP emulsion 90% crystal trichlorfon 10 0 0 times dilution spray, the effect of more than 97.5%.
