Influence of Host Plant Species on the Fecundity Rate of the Two-Spotted Spider Mite, Tertranychus Urticae Koch
MetadataShow full item record
The Two-spotted spider mite, Tetranychus urticae Koch is a serious pest to greenhouse cultivation. Attempts at controlling the mite have been unsuccessful. This study was designed to measure fecundity rates of the spider mite on different species of host plants commonly grown in greenhouses. The basic hypothesis of the study was that spider mites would tend to reproduce more quickly on some types of host plants than on others. The purpose of finding if there are differences in fecundity rates on different host plant species is to determine if different biological control methods need to be applied to the separate host plant species. The host plants used in this study were bean, rose, Schefflera, and Diefenbachia. The mites seemed to reproduce quickly on rose and bean plants and slowly on Schefflera and Diefenbachia plants, under the specific conditions of this study.
