Population dynamics of the yellow spider mite in raspberry fields have been studied in 1992. The relationship was established between leaflet and leaf occupation. Timing of sampling was defined and thresholds were proposed. The most efficient strategy was a treatment after the harvest just before the yellow spider mite entered diapause.

Huang Jian | Huang Bangkan | Luo Xiaonan (Fujian Agricultural Univ., Fuzhou (China). Dept. of Plant Protection)
The scale insects are very important pests on fruit trees. Using natural control by the hymenopterous parasites is the major way to biological control and integrated management of the scale insects on fruit trees. This paper deals with studies on parasitic resources of the scale insects on fruit trees and records 5 families, 25 genera and 63 species of hymenopterous parasites
