Fifty greenhouse whitefly (Trialeurodes) were placed in each of 10, one-meter square nylon chiffon cages containing nine regal geraniums in 6-inch pots. After allowing the whitefly to reproduce for 2 weeks, the treatments tested were Delphastus pusillus alone, Azatin sprays alone, D. pusillus and Azatin together, and no control method. Two repetitions for each treatment were conducted. The Azatin, 14 oz/100 gallons, and a spreader/sticker were applied weekly with a mist sprayer. Delphastus pusillus, nine per cage, were released every 2 weeks. Sampling was conducted weekly by placing yellow sticky traps into each box for a 24-hour period, then counting the number of adults caught. All treatments gave statistically significant fewer whitefly than the cages with no control method. The cages with Azatin and/or D. pusillus were not statistically different from each other. Results indicate that D. pusillus can control whitefly as well as a growth regulator/botanical insecticide.

AbstractThe placement of yellow sticky traps in relation to greenhouse-grown tomato plants affected the number of greenhouse whiteflies captured on traps. Whiteflies were caught on traps close to the ground when the traps were 1.0 m or more from plants, and were caught on traps level with the point from which they started flight when the traps were 0.5 m from plants. Traps 1.0 m from plants primarily caught whiteflies less than 5 days old, and trap catches were not correlated with numbers on plants; traps 0.5 m from plants caught whiteflies of all ages, and trap catches were correlated with numbers on plants. These results suggest that under field conditions greenhouse whiteflies would behave much like other species of whitefly, and would tend to be caught on traps close to the ground. In greenhouses, monitoring traps should be placed close to and slightly below the tops of the plants. Trap counts could be treated as samples from individual plants and used to make an estimate of population size in the greenhouse. Traps placed further from the plants monitor flight activity only.

Winter Time

In the unheated plastic greenhouses of Crete, the control of the greenhouse whitefly Trialeurodes vaporariorum Westwood using chemicals is usually needed during winter time. The systemic insecticide Vydate when applied as soil granules at the highest dose (2g/plant), gave protection for young eggplants against whitefly for a period of 5 weeks. Experiment with different chemicals showed that the new insect growth regulator Nomolt, is fairly effective in controlling the greenhouse whitefly when used in combination with Actellic. It gave equally good results when compared with a mixture of Applaud and Actellic.
