| Abstract:
Weeds, animals, humans and some physical structures were registered as hosts or sources of infestation of "carmine spider mite" Tetranychus cinnabarinus (Boisduval) on carnation crops. Mite populations were monitored in dry and rainy seasons under greenhouse conditions of commercial carnation nurseries. Results show that leaves and flowers of carnation and weeds were the most important sources of mite spread, followed by wooden frames, strings irrespective of their material, plastic surfaces and collecting carts for cut flowers. Other carriers were clothing, hair and body of workers, farm tools, insects and birds. Garbage deposits and littering, resting areas of workers and buildings rarely showed the presence of mites. Moreover, the presence of one female mite on any host or place could represent a potential danger for carnation crops. | |
