Abstract:
Some plants are more attractivee to agricultural, pests than the crop to which they are a pest. The use of these plants as indicator plants to monitor pest populations is examined. Bean plants were found to be effective indicators for forecasting the growth of carmine spider mite, Tetranychus sinnabarintus (Boisduval), on greehouse tomatoes, Lycopersicum exculentum L. Spider mite populaton growth rates were the same on both host plants, but because they became estabilished up to 5 wk earlier on beans, Phaseolus culgaris L., monitoring carmine spider mite population growth on beans provides enough time to order and distribute natural enemies for their control on tomatoes. The oviposition and developmental rates of mites did not differ on the 2 host plants. However, the temperature threshold for oviposition was 7°C lower on beans than tomatoes, in earlier establishment and onset of population growth in the spring on the indicator plants. The potential for using indicator plants to establish bioligical control agents was investigated with the predatory mite Phytosciulus persimilis Athias-Henriot. P. persimilis became established equally well when broadcast on the crop (with its much lower prey population density) as when released only on infested indicator plants. Best control of carmine spider mites by Phytosciulus was obtained when the predators were released when spider mite density reached 12 per tomato leaf, which occurred when the mite density on beans was 100 per leaf, 5 wk after reaching 12 mites per bean leaf. Acting on this threshold, a grower would have ample time to order, recieve, and release predatory mites. Predation of spider mites by Phytosciulus was higher on the tomatoes than the beans. Phytosciulus populations dipped after introduction on both host plants but recovered more rapidly on beans. The different predation and survival rates on the 2 host sustaining the population interactions.
