Predatory Behavior of Long-Legged Flies (Diptera: Dolichopodidae) and Their Potential Negative Effects on the Parasitoid Biological Control Agent of the Asian Citrus Psyllid (Hemiptera: Liviidae)

Apparently because of mulch buildup and abstinence from pesticide use, an organically managed citrus grove in Vero Beach, Florida, can support large populations of long-legged flies (Diptera: Dolichopodidae) that impose predation pressure on inundative releases of Tamarixia radiata (Waterston) (Hymenoptera: Eulophidae) parasitoid wasps to control the Asian citrus psyllid (Hemiptera: Liviidae). During peak activity, flies on wing...
