초록

The potential of the predatory mite Phytoseiulus persimilis (Acarina : Phytoseiidae)to control two spotted spider mite Tetranychus urticae (Acarina : Tetranychidae)was investigated on sustainable strawberry fields in Jeonnam area. The density ofT. urticae increased from 4th and 7th weeks after single and two timings releaseP. persimilis, respectively. On the three timings of release plot, number(density) ofT. urticae on a leaf maintained fewer than 10 during the 15 weeks after release.
In the 1,000 release of P. persimilis per 100m2 plot, P. persimilis could notsuppress T. urticae. In the 2,000 release plot, P. persimilis could suppress T.
urticae with low density which was the similar in the 3,000 release plot. Twospottedspider mite, T. urticae, occurred from late March and increased density inHampyeong area. In the P. persimilis released field, T. urticae inhibited continuouslyafter release. In Boseong area, density of P. persimilis increased 50 per10 leaves through increasing of T. urticae. Percent of occurrence of T. urticaeshowed high 10.5~75.5% in none-release predatory mite but not high in releasetreatment. T. urticae on sustainable strawberry field could be inhibited by P.persimilis.
