- Abstract
Flight mills were used to investigate flight capabilities of Allograpta obliqua (Say) (Diptera: Syriphidae), an important predator of Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), in California. Specifically, distance by which A. obliqua can fly in 24 h, and the effect of sex and feeding treatment (fed or starved) on flight capabilities were investigated. A total of 17 (7 females, 10 males) laboratory-reared flies were flown. There was no significant effect of sex on distances flown. Out of a total of 3,487 flight bouts, 7 consisted of A. obliqua flying 1 to 2 m, and 5 bouts consisted of A. obliqua flying over 5 m. The remaining bouts (99.7%) were less than 1 m and were considered 'hovering' because they consisted of extremely short bursts of flight activity (< 10 s). The 5 bouts over 5 m were conducted by 2 fed females, and the mean distance flown and mean flight bout time were 39 ± 13 m and 113 ± 24 s, respectively.
